In some embodiments, the pushing block 310 can be directly pushed by one hand to integrally move the sliding member 300, and the limiting block 320 abuts against the inner peripheral edge of the guide hole 110 through itself to play a limiting role, so that the sliding member 300 is prevented from falling out of the guide hole 110, and the sliding member 300 can normally operate.

In some embodiments of the present invention, the top surface of the pushing block 310 is provided with a plurality of anti-slip grooves 311. By arranging the anti-slip groove 311, the friction coefficient of the top surface of the push block 310 is improved, so that the sliding of the sliding member 300 is more convenient and effective.

In some embodiments of the present invention, the limiting comb body 200 includes comb teeth 210 and a limiting plate 220, the comb teeth 210 are fixedly connected to the limiting plate 220, the first rack 240 is disposed on an upper end surface of the limiting plate 220, and the limiting plate 220 can cover the receiving groove 160. The comb teeth 210 are a core portion of the limiting comb body 200 and are used for limiting a cutter head of the hair clipper, and the limiting plate 220 can cover the accommodating groove 160, so that the accommodating groove 160 forms a closed chamber, and limit internal components such as the slider 300, the second gear 420 and the first gear 410, and prevent the internal components such as the slider 300, the second gear 420 and the first gear 410 from falling out of the accommodating groove 160.

Further, in some embodiments of the present invention, as shown in fig. 6, two sides of the position-limiting plate 220 are respectively abutted against two side walls of the accommodating groove 160, the position-limiting plate 220 divides the accommodating groove 160 into an accommodating chamber 161 and an installation groove 162, and the second gear 420, the first gear 410, the second rack 130 and the first rack 240 are all disposed in the accommodating chamber 161. The inner wall of the accommodating chamber 161 can limit the internal components such as the sliding member 300, the second gear 420 and the first gear 410, and prevent the internal components such as the sliding member 300, the second gear 420 and the first gear 410 from falling out of the accommodating chamber 161, the mounting groove 162 is used for connecting and matching the hair clipper with the fixing shell 100, and in practical application, the shell of the hair clipper is inserted and fixed in the mounting groove 162 in a sliding and inserting manner, so that the limiting comb adjusting mechanism is fixed on the hair clipper.

In some embodiments of the present invention, a plurality of positioning protrusions 140 are disposed on the sidewall of the receiving groove 160.

Specifically, the hair clipper has a housing that is removably connected to a stationary housing 100 of the spacing comb adjustment mechanism to enable installation of the spacing comb adjustment mechanism. More specifically, in combination with some embodiments described above, the fixing shell 100 is provided with a mounting groove 162, the housing of the hair clipper is inserted and fixed in the mounting groove 162, so as to implement the mounting of the limiting comb adjusting mechanism, and the housing of the hair clipper is provided with a positioning groove for the positioning protrusion 140 on the side wall of the receiving groove 160 to cooperate, so that the fixing shell 100 and the housing are more stably and reliably connected.

When the spacing comb body 200 is adjusted, the sliding member 300 is pushed, the sliding member 300 drives the second gear 420 and the first gear 410 to move synchronously, the second gear 420 is engaged with the second rack 130 on the fixed shell 100, so that the second gear 420 rotates during the moving process, and the second gear 420 and the first gear 410 are fixed concentrically, thereby driving the first gear 410 to rotate, the first gear 410 is engaged with the first rack 240 on the spacing comb, so that the first rack 240 moves in the same direction as the sliding member 300 and drives the spacing comb body 200 to move in the same direction, since the moduli of the second gear 420 and the first gear 410 are different, the moving distance of the sliding member 300 and the moving distance of the spacing comb body 200 are not the same in the same time, and adjustment of various different strokes can be realized, for example, when the modulus of the second gear 420 is greater than the modulus of the first gear 410, that the pitch of the second gear 420 is greater than the pitch of the first gear 410, the rotation angles of the second gear 420 and the first gear 410 are the same, and the maximum moving stroke of the sliding part 300 is larger than that of the limiting comb, so that the limiting comb can be finely adjusted more accurately, and the adjustment accuracy of the limiting comb is improved; when the module of the second gear 420 is smaller than that of the first gear 410, the second gear 420 and the first gear 410 rotate by the same angle, and the maximum moving stroke of the slider 300 is smaller than that of the limit comb, so that the limit comb has a larger adjusting stroke, and the flexibility of adjusting the limit comb is improved. It can be seen that, since the modules of the second gear 420 and the first gear 410 are different from each other, the sliding member 300 and the spacing comb body 200 are not moved synchronously due to the gear change conversion, so that more adjustment conditions can be adapted, and the applicability of the hair clipper is improved.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The present embodiment has been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above-described embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the present invention.
