Wherein, the abutment portions 52 may be provided with two, two abutment portions 52 are provided on opposite sides of the hinge 5, specifically on opposite sides of the body portion 54, and accordingly, the pressing portions 41 are preferably provided with two, two pressing portions 41 are provided on opposite sides of the button 4, and each abutment portion 52 is adapted to abut against one pressing portion 41, so that the pressing force can uniformly act on the hinge 5 when the pressing portion 41 abuts against the hinge 5 and applies the pressing force to the opposite sides of the hinge 5.

The driving part 53 may serve as a force application end of a lever structure formed by the hinge 5, and the driving part 53 may serve to drive the panel assembly 3 to move. Specifically, when the button 4 abuts against the abutting portion 52 of the hinge 5 and a pressing force is applied to the abutting portion 52, the driving portion 53 of the button 4 rotates about the hinge portion 51, for example, the driving portion 53 rotates toward the panel assembly 3 to drive the panel assembly 3 to move. Wherein the driving part 53 may apply a driving force to the middle position of the panel assembly 3 to improve the smoothness of the panel assembly 3 when moving.

Compared with the fact that the button is arranged in the middle of the panel assembly 3 and is inconvenient for a user to operate (when the user holds the handle, the pressed finger, generally the thumb, is far away from the button and is inconvenient to apply force to press, so that two hands are required to be matched for use, the operation is complex, and the experience is poor), the hinge 5 is arranged to form a lever structure, the pressure is applied by pressing the button 4 which is not arranged in the middle of the panel assembly 3 (but is close to the handle 2), the lever structure can enable the other position (the driving part 53) of the lever structure to move, and the pressure is applied to the middle of the panel assembly 3. Accordingly, the user can apply a pressing force to a position adjacent to the handle joint 2 by one hand to press the button 4 while holding the handle, and apply a pressing force to the middle position of the panel assembly 3 through the hinge 5, driving the panel assembly 3 to move smoothly.

In some embodiments, the driving portion 53 and the hinge portion 51 are disposed at opposite ends of the abutment portion 52, for example, the hinge portion 51 and the driving portion 53 are disposed at both ends of the body portion 54, specifically, the abutment portion 52 is disposed at a middle position of the body portion 54, the hinge portion 51 is disposed at an end of the body portion 54 near the handle joint 2, and the driving portion 53 is disposed at an end of the body portion 54 facing away from the hinge portion 51. Therefore, the distance from the driving portion 53 to the hinge portion 51 is greater than the distance from the abutment portion 52 to the hinge portion 51, and the moment at the driving portion 53 is greater, at which time the lever structure formed by the hinge 5 is in the form of a laborious lever. Since the driving portion 53 is further away from the hinge than the abutting portion 52, when the hinge 5 rotates around the hinge portion 51 by a certain angle, the rotation path of the driving portion 53 is more than that of the abutting portion 52, and therefore, the abutting portion 52 is driven by the button 4 to move less by a displacement, the driving portion 53 can realize a more mobile displacement, the movement amount of the abutting portion 52 is proportional to the movement amount when the button 4 is pressed, the movement amount of the driving portion 53 is proportional to the movement distance of the panel assembly 3, that is, a small amount of movement amount when the button 4 is pressed, that is, the panel assembly 3 can be driven to move more distance. Specifically, after the button 4 moves by one unit distance in the pressing direction, the abutting portion 52 of the hinge 5 is pressed by the button 4 to move by one unit distance in the pressing direction of the button 4, and the driving portion 53 moves by 1.6 to 5 unit distances in the pressing direction of the button 4, at which time the panel assembly 3 is driven by the driving portion 53 to move by 1.6 to 5 unit distances in the pressing direction of the button 4, that is, the distance by which the panel assembly 3 moves in the pressing direction of the button 4 is 1.6 to 5 times the distance by which the button 4 moves in the pressing direction thereof.

In the existing comb, the moving distance of the panel assembly 3 is the same as or similar to the pressed distance of the button 4, the maximum displacement of the button 4 when pressed is generally about 4mm, the maximum displacement of the panel assembly 3 in the existing comb is also about 4mm, and the maximum displacement of the panel assembly 3 about 4mm is also about 4mm, so that the cleaning effect of the panel assembly 3 on hairs attached to comb teeth is reduced. The hinge piece 5 is in a laborious lever structure, so that the panel assembly 3 can be moved more distance by pressing the button 4 by a smaller amount, and the cleaning effect of the panel assembly 3 on hairs attached to the comb teeth is improved. Specifically, the maximum displacement of the panel assembly 3 in the pressing direction of the button 4 is 1.6 to 5 times the maximum displacement of the button 4 in the pressing direction of the button 4 when the button 4 is pressed, specifically, the maximum displacement of the panel assembly 3 in the pressing direction of the button 4 when the button 4 is pressed may be 2 to 6mm, preferably 4mm, and the maximum displacement of the panel assembly 3 in the pressing direction of the button 4 may be 6 to 14mm, preferably 10mm.
