(17) The first cutting portion 100 is disposed in order to cut a target, and includes a first cutting blade 110, 111, 112, 113 or 114, and a first 120, 121, 122, 123 or 124. Each of the first cutting blades 110, 111, 112, 113 and 114 includes a cutting surface inclined in one direction in order to cut the target.

(18) The first supporter 120, 121, 122, 123 or 124 extends from one end of the first cutting blade 110, 111, 112, 113 and 114 for supporting the first cutting blade 110, 111, 112, 113 or 114 and is formed integrally with the first cutting blade 110, 111, 112, 113 or 114. At least one first supporter 120, 121, 122, 123 or 124 may be formed according to the look of the first cutting blade 110, 111, 112, 113 or 114.

(19) The second cutting portion 200 cuts a target in contact with one surface of the first cutting portion 100, and includes a second cutting blade and a second supporter. The second cutting blade cuts the target in contact with one surface of the first cutting blade 110, 111, 112, 113 or 114, and includes a cutting surface inclinedly formed at one side thereof in one direction.

(20) The first frame portion 300 is joined with the first supporter 120, 121, 122, 123 or 124 of the first cutting portion 100 so as to support the first cutting portion 100, and may extend from one side of the first cutting portion 100 so as to be formed integrally with the first cutting portion 100 or may be formed separately from the first cutting portion 100 and joined with the first cutting portion 100.

(21) In the case that the first frame portion 300 is formed separately from the first cutting portion 100 and joined to the first cutting portion 100, the first frame portion 300 includes a fixing plate 310, 311 or 312 which fixes the first supporter 120, 121, 122, 123 or 124, and a fixing groove formed in one side of the fixing plate 310, 311 or 312 so that the first supporter 120, 121, 122, 123 or 124 is inserted and joined to the fixing plate 310, 311 or 312.

(22) The second frame portion 400 is joined with the second supporter of the second cutting portion 200 so as to support the second cutting portion 200, and may extend from one side of the second cutting portion 200 so as to be formed integrally with the second cutting portion 200, or may be formed separately from the second cutting portion 200 and be joined with the second cutting portion 200.

(23) In the case that the second frame portion 400 is formed separately from the second cutting portion 200 and joined with the second cutting portion 200, the second frame portion 400 includes at least one fixing plate 410, 411 or 412 which fixes the second supporter and a fixing groove formed in one side of the fixing plate 410, 411 or 412 so that the second supporter is inserted and joined to the fixing plate 410, 411 or 412.

(24) In the meantime, according to forms of the first cutting blades 110, 111, 112, 113 and 114 and the second cutting blades, a plurality of supporters which support the cutting blades may be formed, and thus, the number of he fixing plates or the fixing grooves for fixing the supporters may be changed.

(25) In the case that the first frame portion 300 and the second frame portion 400 are formed separately from the first cutting portion 100 and the second cutting portion 200, the first cutting blades 110, 111, 112, 113 and 114 or the second cutting blades which are worn out due to a long-term use can be easily replaced. Moreover, because the first cutting portion 100, the second cutting portion 200, the first frame portion 300 and the second frame portion 400 are hingedly coupled by one coupling portion 500, the rounded blade scissors 10 can be easily manufactured and can be reduced in manufacturing cost.

(26) Meanwhile, the first frame portion 300 and the second frame portion 400 respectively have circular gripping means formed at one end thereof so that a user can grip the scissors with his or her fingers, and the first cutting portion 100 and the second cutting portion 200 are respectively formed at right angles to the gripping means relative to the plane of the gripping means.

(27) The coupling portion 500 joins the first frame portion 300 and the second frame portion 400 by a hinge so as to cut the target by getting in contact with the second cutting portion 200 by rotation of the first cutting portion 100. That is, the first cutting portion 100 and the second cutting portion 200 are rotatable on the coupling portion 500 in right and left directions.

(28) The contact preventing members 130, 131, 132, 230 or 231 are disposed on at least one of the first cutting portion 100 and the second cutting portion 200, and separate a portion of the first cutting portion 100 or the second cutting portion 200 when the first cutting portion 100 gets in contact with the second cutting portion 200. Furthermore, a plurality of the contact preventing members 130, 131, 230 or 231 may be formed according to forms of the first cutting portion 100 and the second cutting portion 200.

First Embodiment

(29) The first cutting blade 110 according to the first preferred embodiment of the present invention is formed in a hook which is bent roundly with a predetermined curvature, and the second cutting blade 210 is formed in a closed annular shape so as to surround the outer circumferential surface of the first cutting blade 110. As shown in FIG. 2, in the case that the first cutting blade 110 is in contact with the second cutting blade 210, the first cutting blade 110 is close to the bottom of the second cutting blade 210 of the annular shape.

(30) The contact preventing member 130 according to the first preferred embodiment of the present invention is located between the first cutting blade 110 and the first supporter 120. When the outer circumferential surface of the first cutting blade 110 comes in contact with the inner circumferential surface of the second cutting blade 210, the contact preventing member 130 is bent from the outer circumferential surface of the first cutting portion 100 toward the inner circumferential surface so that a portion of the first cutting portion 100 is separated from the second cutting portion 200, thereby creating an empty space between the second cutting portion 200 and the contact preventing member 130.

(31) In other words, only the first cutting blade 110 and the second cutting blade 210 which respectively have the cutting surfaces are in contact with each other and an empty space is formed between the first cutting portion 100 and the second cutting portion 200 by the contact preventing member 130 formed on the first cutting portion 100, such that the rounded blade scissors according to the preferred embodiment of the present invention can prevent deterioration of cutting efficiency by nose hair getting in the remaining portion except the first cutting blade 110.

(32) On one side of the second cutting blade 210 which is in contact with the first cutting blade 110, an uneven portion 240 of a zigzag shape is formed on one side of the second cutting blade 210 which is in contact with the first cutting blade 110. In FIG. 2, the uneven portion 240 is formed in a serrated shape, but the uneven portion may adopt any shape if it is formed in the zigzag shape having a curve, and as occasion demands, the first cutting blade 110 which comes into contact with the uneven portion 240 of the second cutting blade 210 may also have such an uneven portion 240.

(33) Meanwhile, as shown in FIG. 4, the first cutting blade 110 is formed in such a manner that a straight distance in a radial direction from a central point 600 of the second cutting blade 210 to the first cutting blade 110 is gradually reduced from one end of the first cutting blade 110 to the other end of the first blade 110 toward the contact preventing member. Here, the central point 600 of the second cutting blade 210 means a point for forming a substantially annular circumference of the second cutting blade 210.

(34) Therefore, when the outer circumferential surface of the first cutting blade 110 comes into close contact with the inner circumferential surface of the second cutting blade 210 by the user, a predetermined pressure is generated while the first cutting blade 110 comes into close contact with the second cutting blade 210, and in this instance, the cutting efficiency is increased by the generated pressure.

(35) As shown in FIG. 5, the fixing plate 310 of the first frame portion 300 is located between the two fixing plates 410 of the second frame portion 400 and rotates on the coupling portion 500 so as to carry out a cutting action.

(36) In the meantime, because the first cutting blade 110 and the second cutting blade 210 respectively have the cutting surfaces inclined in one direction, if the user's nose hair is located on the uneven portion of the second cutting blade 210, the first cutting blade 110 slides along the inclined cutting surface of the second cutting blade 210 in the state where it is in contact with the second cutting blade 210 so as to carry out the cutting action, thereby enhancing cutting efficiency.

Second Embodiment

(37) The cutting blade 111 according to the second preferred embodiment of the present invention is formed in a hook and the second cutting blade 211 is formed in a closed annular shape.

(38) As shown in FIG. 7, the contact preventing means 230 of the second preferred embodiment is located between the second cutting blade 211 and the second supporter 221, and has a separation groove recessed from the inner circumferential surface of the second cutting portion 200 in a direction of the outer circumferential surface. That is, the contact preventing means 230 separates a portion of the second cutting portion 200 from the first cutting portion 100 when the outer circumferential surface of the first cutting blade 111 comes into contact with the inner circumferential surface of the second cutting blade 211.

(39) It is also possible that the first cutting blade 111 or the second cutting blade 211 of the second preferred embodiment has the same uneven portion 240 as the first preferred embodiment. The first cutting blade 111 is formed in such a manner that a straight distance from a central point 600 of the second cutting blade 211 to the first cutting blade 111 is gradually reduced from the first cutting blade 111 to the first supporter 121.
