Technical Field

[0001] This utility model relates to the field of hairdressing technology, specifically to a connecting structure for the swing head of a hair clipper. Background Technology

[0002] Hair clippers, as products used for cutting hair, are technologically mature products. However, some of their components break after prolonged use, indicating that the product's structure and material design need improvement. In existing hair clippers, the connection between the motor and the swing head is fixed using a film. However, the film generates resistance during the swinging motion, which occurs at high speeds. Over time, the film cracks or breaks, requiring replacement of parts. This results in a short product lifespan, and non-professionals are hesitant to disassemble it. Therefore, we need to redesign a new structure to address the problems in existing technology and solve the issue of swing arm breakage. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a connecting structure for the swing head of a hair clipper, replacing the film with a supporting swing rod. The supporting swing rod experiences no resistance during swinging, thus preventing cracking or breakage.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-7 This utility model provides a technical solution: it includes a hair clipper body 1 and a blade assembly 3. The hair clipper body 1 houses a motor 2, and a fixed housing 21 is located on one side of the motor 2. Movable support swing rods 5 are connected to both ends of the fixed housing 21. A movable swing head 4 is connected to one end of the support swing rod 5. An eccentric shaft 22 driven by a motor is connected to the middle of the swing head 4. A swing block 41 is located at the front end of the swing head 4. A moving blade 31 is connected to the swing block 41, and a fixed blade 32 is attached to the lower surface of the moving blade 31. By replacing the film with the support swing rod 5, the film generates resistance during swing, which can cause it to crack or break. Cracks and breaks require replacement, resulting in a shorter lifespan and higher long-term replacement costs. The support swing rod 5, however, provides no resistance during swing and is less prone to cracking or breakage, resulting in a longer lifespan and reduced costs.

[0015] read Figure 6 As shown, a bearing 23 is provided at the front end of the eccentric shaft 22, and the bearing 23 is adapted to and movably connected to the groove 401 of the swing head 4. The swing head 4 is driven to swing by the bearing 23. The swing head 4 and the swing block 41 are an integral structure, so when the swing head 4 swings, it will also drive the swing block 41 to swing.

[0016] read Figure 3 As shown, screws or pins are provided between the swing head 4 and the supporting swing rod 5, and screws or pins are provided between the fixed shell 21 and the supporting swing rod 5. The two supporting swing rods 5 are symmetrically arranged. Both the fixed shell 21 and the two supporting swing rods 5 are provided with through holes, so the two supporting swing rods 5 can be movably connected to the fixed shell 21 by inserting screws or pins. The two ends of the swing head 4 are also provided with through holes corresponding to the two supporting swing rods 5, so the two supporting swing rods 5 can be movably connected to the swing head 4 by inserting screws or pins.

[0017] The swing block 41 has a buffer groove 411 in its middle, and the moving blade 31 has a through groove 311 in its middle. The swing block 41 and the moving blade 31 are inserted into and connected to each other through groove 311. The swing block 41 and the swing head 4 are an integral structure, so the swing head 4 will also drive the swing block 41 to swing during the swinging process. The swing block 41 is inserted into and connected to the moving blade 31 through groove 311, so the moving blade 31 will swing along with the swing block 41. The buffer groove 411 can absorb the impact and alleviate pressure fluctuations.

[0018] A spring piece 321 is provided on one side of the fixed blade 32. One end of the spring piece 321 is fixedly connected to the fixed blade 32, and the other end is elastically connected to the moving blade 31. A V-shaped groove 312 is provided on the surface of the moving blade 31, and the end face of the spring piece 321 abuts against the surface of the V-shaped groove 312. The abutment between the end face of the spring piece 321 and the surface of the V-shaped groove 312 tightly presses the moving blade 31 against the outer surface of the fixed blade 32, reducing hair residue and jamming between the blades by eliminating excess gaps.

[0019] It should be noted that the V-groove 31 designed in this patent can be designed as a U-shape or other groove shape, as long as it can be pressed against by the spring piece 321, in order to prevent the moving tool from separating from the fixed tool.

[0020] A limiting metal block 6 is provided on the outer side of the swing block 41. The limiting metal block 6 is connected to the outer surface of the fixed blade, and a torsion spring mechanism is provided between the limiting metal block 6 and the fixed blade 32. The limiting metal block 6 limits the swing range of the swing block 41 and prevents excessive swing.

[0021] The hair clipper body 1 is equipped with a circuit board, control buttons and a battery. The circuit board, control buttons and battery are connected to the motor 2 by wires. These are all conventional design features of hair clippers, so no description is given of these control details.

[0022] Working principle; The motor 2 is electrically connected to a control button, circuit board, and battery. The control button turns on the motor 2. A fixed housing 21 is located on one side of the motor 2, and a movable swing head 4 is connected to one end of the fixed housing 21. The motor 2 drives an eccentric shaft 22 on its outer surface to rotate. A bearing 23 is fitted to the front end of the eccentric shaft 22, and the bearing 23 is movably connected to a groove in the middle of the swing head 4. The swing head 4 and the supporting swing rod 5 are movably connected and fixed by screws or pins. The fixed housing 21 and the supporting swing rod 5 are also movably connected and fixed by screws or pins. Therefore, when the motor 2 starts to drive the eccentric shaft 22 to rotate, the swing head 4 will also swing. The swing head 4 swings and drives the support swing rod 5 to swing as well. During the swing of the swing head 4, the swing block 41 is inserted into the through slot of the moving blade 31. When the swing block 41 swings, it drives the moving blade 31 to move left and right. In addition, when the moving blade 31 swings, its upper surface abuts against the surface of the V-groove 312 of the power through the spring piece 321, so that the moving blade 31 abuts against the upper surface of the fixed blade 32. This working principle can make the gap between the two blades smaller and the shearing effect better.
