[0034] Combination Figures 1-8 As shown, this utility model provides a wrench adjustment structure for electric clippers, including a wrench assembly 2, a blade holder assembly 3, and a moving blade 4 disposed at the head end of the electric clipper body 1. The blade holder assembly 3 is slidably mounted on the electric clipper body 1, and the moving blade 4 is movably disposed at one end of the electric clipper body 1 and engages with the fixed blade of the blade holder assembly 3 for shearing. The wrench assembly 2 is used to drive the blade holder assembly 3 to move, thereby adjusting the haircutting length.

[0035] See Figures 3 to 5 The wrench assembly 2 includes an adjusting wrench 21 rotatably mounted on one side of the blade holder assembly 3, a limiting shaft 22 connected to the electric clipper body 1, and a sliding connector 23 slidably mounted inside the adjusting wrench 21. The adjusting wrench 21 is sleeved on the limiting shaft 22 and can rotate around the limiting shaft 22. The adjusting wrench 21 is driven by the blade holder assembly 3 and is used to drive the blade holder assembly 3 to move. One end of the limiting shaft 22, which is located inside the adjusting wrench 21, is provided with a gear part 221, and the gear part 221 and the limiting shaft 22 are designed as an integral structure. The sliding connector 23 has a toothed part 231 at one end facing the gear part 221, which can mesh with the gear part 221. The direction of movement of the sliding connector 23 is perpendicular to the axial direction of the limiting shaft 22.

[0036] Compared to the complex structure of existing technologies that employs numerous components and two gear parts, this wrench assembly consists only of main components such as an adjusting wrench, a limiting shaft, and a sliding connector. This reduces the number of components, making the overall structure simpler and lowering manufacturing costs. By directly meshing the gear part of the limiting shaft with the toothed part of the sliding connector, the complex fixed and moving gear structure is replaced, further simplifying the design, reducing manufacturing difficulty, and lowering production costs.

[0037] In some embodiments, such as Figure 5 and Figure 6 As shown, the wrench assembly 2 also includes a spring 24 installed between the sliding connector 23 and the adjusting wrench 21. Under normal conditions, the spring 24 engages the toothed portion 231 and the gear portion 221. This structure, by adding a spring, keeps the toothed portion and gear portion engaged under normal conditions. When the adjusting wrench rotates, the spring is compressed, disengaging the toothed portion 231 and the gear portion 221, allowing the adjusting wrench to rotate smoothly. When rotation stops, the toothed portion 231 and the gear portion 221 engage under the force of the spring, thereby locking the adjusting wrench 21 and preventing accidental rotation during the use of the electric clipper, thus improving the stability and reliability of its use.

[0038] In some embodiments, such as Figure 5 , Figure 6 and Figure 8 As shown, the end of the sliding connector 23 opposite to the toothed portion 231 has a recessed spring limiting groove 232. The adjusting wrench 21 has a limiting block 211 opposite to the spring limiting groove 232. The spring 24 is placed within the spring limiting groove 232, with one end of the spring 24 abutting against the limiting block 211 and the other end abutting against the bottom of the spring limiting groove 232. This structure, with the spring limiting groove and limiting block working together to limit the spring, makes the sliding of the sliding connector more stable, thereby ensuring the stability of the meshing between the gear portion and the toothed portion, resulting in a stable and reliable structure.

[0039] In some embodiments, such as Figure 5 and Figure 6 As shown, a sliding groove 212 for sliding connector 23 is formed on one side of the limiting block 211. A cover plate 27 is fixed on one side of the sliding groove 212. The cover plate 27 covers the sliding groove 212 and is used to restrict the sliding connector 23 from coming out of the sliding groove 212. It also facilitates the installation of the sliding connector 23. The cover plate 27 is fixed to the limiting block 211 by a first fastener 25. The first fastener 25 can be a fastening screw. The limiting block 211 is provided with a threaded hole that is threaded to the fastening screw.

[0040] In some embodiments, such as Figure 3 and Figure 4 As shown, a limiting insertion part 222 is provided at the end of the limiting shaft 22 away from the gear part 221, and a limiting insertion groove 101 adapted to the limiting insertion part 222 is provided on the side wall of the electric clipper body 1. Both the limiting insertion part 222 and the limiting insertion groove 101 are regular polygons. This structure, with the limiting insertion part and the limiting insertion groove being regular polygons, not only facilitates installation and positioning but also effectively prevents the limiting shaft from rotating during use, ensuring the stability and adjustment accuracy of the adjustment structure.

[0041] In some embodiments, such as Figure 3 and Figure 4As shown, the adjusting wrench 21 has a receiving space 213 for accommodating the gear part 221, and the limiting insertion part 222 is located outside the receiving space 213. A second fastener 26, which can be a screw, passes through the limiting shaft 22. One end of the second fastener 26 is threadedly connected to the electric clipper body 1, thereby locking the electric clipper body 1, the adjusting wrench 21, and the limiting shaft 22 together. In this structure, the limiting shaft is fitted into the limiting insertion groove on the side wall of the electric clipper body through the limiting insertion part, and the second fastener passing through the limiting shaft is threadedly connected to the electric clipper body. This ensures that the electric clipper body, the adjusting wrench, and the limiting shaft are tightly locked together, guaranteeing the overall stability of the wrench adjustment structure and preventing loosening during long-term use, thus improving the reliability of the product.

[0042] In some embodiments, such as Figures 3 to 5 As shown, the end of the adjusting wrench 21 facing the blade holder assembly 3 is provided with a driving protrusion 214. The blade holder assembly 3 is provided with a protrusion groove 301 adapted to the driving protrusion 214, and the driving protrusion 214 is placed in the protrusion groove 301. The blade holder assembly 3 includes a blade holder 31 slidably mounted on the electric clipper body 1 and a fixed blade 32 fixed on the blade holder 31. The moving blade 4 is arranged adjacent to the fixed blade 32 to achieve shearing engagement. The protrusion groove 301 is provided on the blade holder 31, and the blade holder 31 is provided with a clearance waist-shaped groove 302 for avoiding the limiting shaft 22. In this structure, the driving protrusion of the adjusting wrench is adapted to the protrusion groove of the blade holder assembly, which can accurately transmit the driving force of the adjusting wrench, ensure the smooth movement of the blade holder assembly, and achieve accurate adjustment of the haircut length. When the adjusting wrench 21 is rotated, the adjusting wrench 21 drives the blade holder 31 to move through the driving protrusion 214, which in turn drives the fixed blade 32 to move.

[0043] In some embodiments, such as Figure 3 As shown, symmetrical inclined grooves 102 are provided on both sides of the head end of the electric hair clipper body 1. Sliding blocks 303 are formed by bending on both sides of the blade holder 31, and the sliding blocks 303 are placed within the inclined grooves 102. In this structure, the blade holder of the blade holder assembly is placed within the inclined grooves on both sides of the head end of the electric hair clipper body via the sliding blocks on both sides. The inclined grooves guide the blade holder 31, allowing it to slide smoothly on the electric hair clipper body, further ensuring the stability and reliability of the adjustment process.

In particular, the descriptions of the embodiments described later are relatively simple, and relevant parts can be referred to the descriptions of the foregoing embodiments.

[0045] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
