DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(7) Please refer to FIGS. 1 to 11 for a preferable embodiment of the present invention. A stapler 1 of the present invention includes a main body 10, a holder 20 and a positioning member 30.

(8) The main body 10 includes a front end portion 11, the front end portion 11 includes a staple outlet 12 and a plate member 13, and the plate member 13 includes a concave 14 adjacent to the staple outlet 12. The holder 20 is switchably disposed on the main body 10, and the holder 20 includes a plurality of notches 21 with different sizes and a plurality of first positioning portions 22. The positioning member 30 is disposed on the main body 10, and the positioning member 30 is releasably positioned with one of the plurality of first positioning portions 22 so that one of the plurality of notches 21 corresponds to the concave 14 in a front to rear direction, for receiving a portion of a cable. Whereby, after a required one of the plurality of notches 21 is chosen by switching the holder 20, the holder 20 is stably positioned so that the cable can be stably held for stapling.

(9) The main body 10 further includes a striker 15 configured to strike a staple 100. The holder 20 is disposed on the front end portion 11, and the plate member 13 includes a guiding slot 131. The striker 15 is slidably received within the guiding slot 131, which stabilizes the strike to the staple 100. In this embodiment, the holder 20 is rotatably disposed on the front end portion 11, and each of the plurality of notches 21 corresponds to one of the plurality of first positioning portions 22 on a radial direction of the holder 20.

(10) Specifically, each of the plurality of notches 21 includes two straight sides 211 opposite to each other, two shoulders 212 and a concave portion 213. The two shoulders 212 are laterally connected to the two straight sides 211, respectively. The concave portion 213 is connected to an end of each of the two shoulders 212. An extension of the two shoulders 212 divides the notch 21 into a rectangular region 214 and a segment region 215 (FIG. 4). The rectangular region 214 is configured to be applied to a cable 200 which is rectangular or flat (FIG. 10), and the segment region 215 is configured to be applied to a cable 300 which is circular (FIG. 11).

(11) The positioning member 30 includes at least one second positioning portion 31, one of the first positioning portion 22 and the second positioning portion 31 includes a recess, and the other of the first positioning portion 22 and the second positioning portion 31 includes a protrusion releasably positioned within the recess releasably. In this embodiment, the first positioning portion 22 includes the recess, and the second positioning portion 31 includes the protrusion. The recess and the protrusion are simple in structure and stably positionable with each other.

(12) The holder 20 further includes a plurality of size indicative portions 23, and each of the plurality of size indicative portions 23 corresponds to one of the plurality of notches 21 radially, for indicating the size of the notch 21 which is selected. The positioning member 30 further includes a positioning slot 32, and each of the plurality of size indicative portions 23 is releasably engaged within the positioning slot 32. Through rotating the holder 20 to make one of the plurality of size indicative portions 23 engaged within the positioning slot 32, the notch 21 which is required can be selected quickly.

(13) The positioning member 30 is movably disposed on the front end portion 11. Specifically, the plate member 13 further includes a groove 132, the positioning member 30 further includes a projection 33, a base 34 and a shaft 35, and the projection 33 and the shaft 35 extend from the base 34 and are lateral to each other. The projection 33 is slidably received within the groove 132 so that the projection 33 can operate smoothly, stably and precisely.

(14) The stapler 1 further includes an elastic member 40, and the elastic member 40 is disposed between the front end portion 11 and the positioning member 30. Specifically, the elastic member 40 is a coil spring and disposed around the shaft 35, and the at least one second positioning portion 31, the shaft 35 and the coil spring are arranged in line so that the elastic member 40 can stably and effectively urge the positioning member 30 to provide good positioning and recovering effects. Preferably, an end of each of the plurality of size indicative portions 23 is outwardly tapered and includes two bevels 231, and each of the two bevels 231 urges the positioning member 30 and moves into the positioning slot 32 when the holder 20 is switched. Specifically, when the positioning member 30 is moved or the holder 20 is rotated, the bevel 231 of one of the plurality of size indicative portions 23 urges the positioning member 30 to move so that the second positioning portion 31 disengages from the positioning slot 32; when the holder 20 is kept rotating, the bevel 231 of another one of the plurality of size indicative portions 23 urges the positioning member 30 to move so that the another one of the plurality of size indicative portions 23 engages into the positioning slot 32 automatically (FIGS. 5-9), thus being easy and quick to operate.

(15) Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
