[0037] Further, the positioning pin 342 includes a rod portion 3421 and a head portion 3422 fixedly connected to the same axis, and the diameter of the end face where the head portion 3422 and the rod portion 3421 are connected is larger than the diameter of the rod portion 3421, and the elastic member 343 is fitted outside the rod portion 3421, and one end of the elastic member 343 abuts against the head portion 3422 and the other end abuts against the inner wall of the case 11. Along the direction away from the rod portion 3421, the cross-sectional area of ​​the head portion 3422 gradually decreases, and the head portion 3422 of the positioning pin 342 can be inserted into the groove 33221. Accordingly, the shape of the groove 33221 has an opening that is arc-shaped and faces upward so as to match the shape of the head portion 3422 of the positioning pin 342.

[0038] Preferably, a plurality of grooves 33221 are provided, and the plurality of grooves 33221 are spaced apart along the length of the rack 332. When the push button 323 is pressed, the push button 323 immediately causes the push rod 321 to slide, the push rod 321 causes the rack 332 to slide in the slide groove 3412, the rack 332 immediately causes the gear screw 331 to rotate and move, and while the gear screw 331 rotates, the comb plate 311 moves perpendicularly to the rotation direction of the gear screw 331. That is, the reciprocating pushing of the push button 323 finally produces the reciprocating extension and retraction movement of the comb teeth 312. The grooves 33221 in the rack 332 are used to position the rack 332 when the rack 332 slides back and forth, and thus affect the rotation angle and number of rotations of the gear screw 331, and thus affect the up and down sliding stroke of the comb teeth 312, thereby controlling the length of the comb teeth 312 protruding from the face plate 12. By setting the number and positions of the grooves 33221 in the rack 332, the extension stroke and position of the comb teeth 312 can be adjusted and controlled.
