Description

Technical Field

[0001] This utility model belongs to the field of electric clipper technology, and in particular relates to an auxiliary adjustment and protection device for the tooth pitch of an electric clipper head. Background Technology

[0002] With the rapid development of the times, people's pursuit of products is increasingly sophisticated and diverse. To meet the various demands of users, enterprises not only attach great importance to product quality but also develop various user-friendly features. Currently, some electric hair clippers on the market have a fixed tooth pitch that cannot be adjusted. When users use this type of electric hair clipper, out of curiosity about the blades, they may disassemble it for research. However, since they are not professionals, they may encounter a problem during reassembly where the tooth pitch exceeds the fixed tooth pitch, affecting the user experience. Returning the clippers to the manufacturer for repair is time-consuming and costly, resulting in a poor user experience. Therefore, there is an urgent need to design an auxiliary adjustment and protection device for the tooth pitch of electric hair clippers that can solve one or more of the above problems. Utility Model Content

[0003] To address one or more problems existing in the prior art, this utility model provides an auxiliary adjustment and protection device for the tooth pitch of electric clipper heads.

[0014] To make the above-mentioned objectives, features, and advantages of this utility model more readily understood, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model, and the positions (front, back, left, right) are only relative to the components and should not be considered limiting. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0015] like Figs. 1-3 As shown, this utility model provides an auxiliary adjustment and protection device for the tooth pitch of electric clipper heads. The auxiliary adjustment and protection device for the tooth pitch of electric clipper heads includes:

[0016] The cutter head assembly 1 and the protective cover 2 that can be fitted onto the cutter head assembly;

[0017] The cutter head assembly 1 is provided with a first spring 10, which is fully or partially embedded in the movable cutter holder 11. The bottom end of the movable cutter holder 11 is connected to the moving cutter 12, the bottom surface of the moving cutter 12 is connected to the fixed cutter 13, and one end of the fixed cutter is connected to the fixed bracket 14.

[0018] The protective cover 2 has an adjustment hole 20 and a window 21 at its front end. The adjustment hole 20 allows a special screwdriver 22 to pass through. The top of the screwdriver 22 abuts against the first spring 10. With the help of external force, the first spring is forced to move, thereby driving the moving blade 11 to move. The window 21 allows observation of the blade teeth. The protective cover 2 has an assisting block 23 and a limiting block 24 at its rear end. The protective cover 2 can be fitted onto the blade assembly 1.

[0019] Specifically, the cutter head assembly 1 is fitted into the protective cover 2, with the cutting teeth portion fitting around the front end of the protective cover 2. The rear end of the protective cover is equipped with an assisting block 23 and a limiting block 24 that restricts the movement of the cutter head assembly. The protective cover 2 serves to protect the cutter head assembly. When the cutter head assembly needs to detach from the protective cover, external force is applied to the assisting block 23, which forces the limiting block 24 to detach from the cutter head assembly, thus allowing the cutter head assembly to leave the protective cover.

[0020] A window 21 is provided in the middle of the front end of the protective cover, through which the tooth distance between the fixed blade 13 and the moving blade 12 can be observed. Adjustment holes 20 are provided on the left and right sides of the front end of the protective cover. One end of the screwdriver 22 can pass through the adjustment hole 20 and abut against the first spring 10. When an external force is applied to the first spring 10 through the screwdriver 22, the first spring 10 is connected to the movable blade holder 11, and the movable blade holder locks the moving blade 12. Therefore, the first spring 10 can only move forward, thereby driving the moving blade 12 to move.

[0021] Since one end of the first spring is fixed to the fixed bracket 14 by a screw, the spring can move when an external force is applied, or the first spring can be moved by the screw 22 under the action of the screwdriver by loosening the screw, and then fixed. The second spring in the cutter head assembly 1 controls the left and right movement of the movable cutter holder. Its special design does not affect the forward and backward movement of the first spring.

[0022] In some embodiments, the protective cover 2 is integrally injection molded.

[0023] Specifically, the protective cover 2 is integrally injection molded, with a simple and reasonable structure that can be easily fitted into the cutter head assembly to protect the cutter head.

[0024] In some embodiments, the first spring 10 has a crossbar 101 at its front end, and the screwdriver 22 abuts against the crossbar 101.

[0025] Specifically, the front end of the first spring is provided with a crossbar 101, which is partially or completely embedded in the movable tool holder 11. When the crossbar moves, it can drive the movable tool holder 11 to move. When one end of the screwdriver abuts against the crossbar through the adjustment hole 20, external force can be applied to the crossbar 101 through the screwdriver 22, forcing the first spring 10 to move, thereby driving the movable tool holder 11 to move. The movable tool holder then engages the moving blade 12, causing the moving blade to move, thus achieving the purpose of fine adjustment of the tooth pitch.

[0026] In summary, this utility model provides an auxiliary adjustment and protection device for the tooth pitch of electric clipper heads, comprising a blade assembly 1 and a protective cover 2 that can be fitted onto the blade assembly. The blade assembly 1 is provided with a first spring 10, which is wholly or partially embedded in a movable blade holder 11. The bottom end of the movable blade holder 11 is connected to a movable blade 12, and the bottom surface of the movable blade 12 is connected to a fixed blade 13. One end of the fixed blade is connected to a fixed bracket 14. The front end of the protective cover 2 is provided with an adjustment hole 20 and a window 21. The adjustment hole 20 allows a special screwdriver 22 to pass through, with the top end of the screwdriver 22 abutting against the first spring 10. By using external force, the first spring is forced to move, thereby driving the movable blade 11 to move. The window 21 allows observation of the blade teeth. The rear end of the protective cover 2 is provided with an assisting block 23 and a limiting block 24. The protective cover 2 can be fitted onto the blade assembly 1. The device is simple and reasonable in design. This protective cover can both protect the cutter head and allow the moving cutter to move, so as to achieve the purpose of fine adjustment of the tooth pitch. Even non-professional users can quickly and easily adjust the tooth pitch, thereby meeting user needs.

[0027] The structure is reasonably designed, allowing even non-professional users to quickly and easily disassemble, assemble, and adjust the gear pitch without the need for any tools, thus meeting user needs.

[0028] The embodiments described above are merely illustrative of one or more implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
