DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0042]
[0043] A key improvement of this example is that the handle 2 is pivotally connected to the work head 1 by means of a pivotal connection mechanism, so that the connection angle of the two is adjustable to suit different usage environments. The aforementioned pivotal connection mechanism comprises an angle locking structure that can lock and unlock the connection angle of the work head 1 and the handle 2 in a plurality of angular positions.
[0044] The angle locking structure comprises: a plurality of first engaging teeth fixed to the work head 1 and spaced apart in the circumferential direction, a plurality of second engaging teeth fixed to the handle 2 and spaced apart in the circumferential direction, a ring gear adapted to the first and second engaging teeth, and a ring gear drive assembly that drives the ring gear to move so as to be selectively in a first position or a second position.
[0045] When the ring gear is in the first position, the first and second engaging teeth simultaneously mesh with the ring gear, thereby locking the connection angle of the work head 1 and the handle 2 to make the work head 1 and the handle 2 unable to rotate relative to each other. When the ring gear is in the second position, the first engaging teeth mesh with the ring gear while the second engaging teeth are separated from the ring gear, making the work head 1 and the handle 2 relatively rotatable.
[0046] The handle 2, having a substantially C-shaped structure, comprises two spaced work head connection ends 201. The handle 2 is made of a plastic material, so that it has a certain deformability. When an external force is applied to the handle 2, the two work head connection ends 201 are capable of moving toward/away from each other.
[0047] The handle 2 has a C-shaped structure, and the work head 1 can be flipped inside the handle 2 (to get the tool closed), thus reducing the occupation space of the care tool and facilitating package and storage.
[0048] More specifically, with reference to
[0049] The two circular grooves 101 are disposed one in the left and one in the right, with their opening directions away from each other. The circular groove 101 is provided on the circular groove wall with a plurality of axially extending linear inner teeth 103 (i.e., the first engaging teeth described above), which are uniformly spaced apart in the circumferential direction of the circular groove wall of the circular groove 101.
[0050] The two outer ring gears 3 respectively project into the two circular grooves 101 and are respectively movably sleeved outside the two pin shafts 102. The outer ring gear 3 comprises a circular ring body 301, a plurality of linear outer teeth 302 integrally formed on the periphery of the ring body 301 and extending along the axial direction of the ring body 301, and a limit inner flange 303 integrally formed at an axially outer end of an inner hole of the ring body 301. The linear outer teeth 302 are uniformly spaced apart along the outer circumferential direction of the ring body 301.
[0051] The two springs 4 are respectively sleeved outside the two pin shafts 102, and axially clamped between the limit inner flange 303 and the bottom wall of the circular groove 101. The spring 4 exerts an axially outward elastic force on the outer ring gears 3, so that the two outer ring gears 3 have a tendency to move away from each other in the axial direction.
[0052] The two unlocking buttons 5 are respectively axially movably connected to the two work head connection ends 201, and comprise three bosses 501 movably disposed through the side holes 204. The unlocking button 5 is connected to the work head connection end 201 specifically by a screw 6. Specifically, the pin shaft 102 is provided at the end with an axially inwardly extending screw connection hole 104, into which the screw 6 is locked by sequentially going through the unlocking button 5 and the central hole 202. The depth of the screw 6 locked into the screw connection hole is limited, so that the size of the screw 6 outside the screw connection hole is large, making the unlocking button 5 have a certain axial displacement space. Further, a metal gasket is disposed between the screw 6 and the unlocking button 5, and a decorative cover 8 for covering the screw head of the screw 6 is embedded in the unlocking button 5.
[0053] The outer ring gear 3 and the handle 2 are respectively of an integral structure.
[0054] Normally, the outer ring gear 3, under the elastic force of the spring 4, is in the first position moved axially outward, while the linear outer teeth 302 on the outer ring gear 3 mesh simultaneously with the linear inner teeth 103 and the limit engaging teeth 203. Thereby, the connection angle of the work head 1 and the handle 2 is locked, and the work head 1 and the handle 2 cannot be rotated relative to each other.
[0055] When an operator presses the unlocking buttons 5 axially inward, the two unlocking buttons 5 axially approach each other against the elastic force of the spring, and the bosses 501 on the unlocking buttons 5 axially press the outer ring gear 3 such that the outer ring gear 3 moves axially inward to the second position, with the linear outer teeth 302 on the outer ring gear 3 disengaged from the limit engaging teeth 203 and only meshing with the linear inner teeth 103. At this time, the outer ring gear 3 no longer restricts the rotation of the handle 2, and the work head 1 and the handle 2 are relatively rotatable.
[0056] After the unlocking button 5 is released, the outer ring gear 3 is returned to the first position under the elastic force of the spring 4. The connection angle of the work head 1 and the handle 2 is locked again.
[0057] Certainly, the example described above is only intended to illustrate the technical concept and features of the present invention, with the purpose of enabling those skilled in the art to understand and implement the present invention instead of limiting the protection scope of the present invention. Any equivalent alteration or modification made according to the spiritual substance of the main technical solution of the present invention will all fall within the protection scope of the present invention.
