[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment:

[0024] Please refer to Figures 1-5 , the present utility model provides a technical solution:

[0025] A hair clipper with replaceable push heads, comprising a handle 1. An installation bracket 2 is clamped at the top of the handle 1. A fixed cutter head 3 is fixedly installed at the top end of the installation bracket 2. The fixed cutter head 3 is fixedly connected to the installation bracket 2 through a fixing mechanism 4. A movable cutter head 5 is movably installed at the bottom end of the fixed cutter head 3. A movable cutter holder 6 is fixedly connected to the bottom of the movable cutter head 5. A reset elastic frame 7 is installed between the outer side of the movable cutter holder 6 and the installation bracket 2. The top end of the handle 1 and inside the installation bracket 2 is rotatably connected to an eccentric shaft 8, and the top end of the eccentric shaft 8 extends to the inside of the movable cutter holder 6.

[0026] First, a silica gel anti-slip sleeve 101 is sleeved on the outer side of the handle 1. A plurality of anti-slip vertical grooves 102 are opened on the outer side of the silica gel anti-slip sleeve 101. When holding the handle 1 to use the hair clipper, with the cooperation of the silica gel anti-slip sleeve 101 and the anti-slip vertical grooves 102 on its outer side, the grasping force of the handle 1 can be effectively improved, avoiding sliding and slipping off during operation, thereby improving the stability of the hair clipper during operation.

[0027] Furthermore, a plurality of positioning strips 201 are fixedly connected to the outer side of the installation bracket 2. Clamping protrusions 202 are fixedly connected to the bottom ends of the plurality of positioning strips 201. Clamping grooves 203 are opened at the positions corresponding to the plurality of clamping protrusions 202 on the outer side of the handle 1. When installing the installation bracket 2, after passing its center through the eccentric shaft 8, the installation bracket 2 is sleeved on the top end of the handle 1 through the plurality of positioning strips 201, so that the clamping protrusions 202 at the bottom ends of the plurality of positioning strips 201 are clamped into the inside of the clamping grooves 203, thereby fixing the installation bracket 2. Subsequently, by pulling the installation bracket 2 to move the clamping protrusions 202 out of the inside of the clamping grooves 203, disassembly can be carried out, and thus it is convenient to disinfect the installation bracket 2.

[0028] Then, the fixing mechanism 4 includes two groups of sliding rods 401 symmetrically and slidably connected to the inside of the top end of the installation bracket 2. Clamping blocks 402 are fixedly connected to the opposite ends of the two groups of sliding rods 401. A spring 403 is fixedly connected between the two groups of clamping blocks 402. An activity groove 404 is opened at the position corresponding to the clamping block 402 inside the installation bracket 2. A clamping groove 405 is opened at the position corresponding to the clamping block 402 inside the fixed cutter head 3. When using the fixed cutter head 3 and the movable cutter head 5, install the fixed cutter head 3 at the top end of the installation bracket 2. First, pinch the two groups of sliding rods 401 to make the two groups of clamping blocks 402 move relatively inside the activity groove 404. Then, after installing the fixed cutter head 3 at the top end of the installation bracket 2, release the sliding rods 401. Under the reset of the spring 403, the clamping blocks 402 are clamped into the inside of the clamping groove 405, thereby facilitating the disassembly and assembly of the fixed cutter head 3. After the hair clipper completes preoperative skin preparation, after releasing the fixation of the fixed cutter head 3, replace the fixed cutter head 3 and the movable cutter head 5 together, and then disinfect the installation bracket 2. This is not only simple to operate but also can avoid the risk of cross-infection.

[0029] Further, a slider 501 is fixedly connected to the bottom end of the back surface of the movable cutter head 5. The slider 501 is slidably connected to the fixed cutter head 3 through a chute 502. When performing preoperative skin preparation, the rotation of the eccentric shaft 8 drives the movable tool holder 6 to move left and right, thereby driving the movable cutter head 5 to move left and right to shear hair. During this process, the slider 501 slides within the chute 502, thereby improving the stability of the left and right movement of the movable cutter head 5 and avoiding discomfort caused by pulling the hair.

[0030] Secondly, receiving grooves 601 are formed at both the left and right ends inside the movable tool holder 6. The top end of the reset elastic frame 7 abuts against the inner side of the receiving groove 601. The rear end of the reset elastic frame 7 is snap-connected to the mounting bracket 2 through a fixed end 701. The top end of the reset elastic frame 7 abuts against the movable tool holder 6 through the receiving groove 601, enabling the movable cutter head 5 to move left and right close to the fixed cutter head 3, thereby stably shearing hair. The rear end of the reset elastic frame 7 is snap-connected to the mounting bracket 2 through the fixed end 701 for convenient assembly. When the movable cutter head 5 moves left and right, the reset elastic frame 7 always resets the movable cutter head 5 to the middle position, enabling the movable cutter head 5 to continuously move left and right to shear hair.

[0031] Finally, a motor is fixedly installed at the top end inside the handle 1. The driving end of the motor is fixedly connected to the eccentric shaft 8. The eccentric shaft 8 is rotatably connected to the mounting bracket 2 through a bearing 801. The motor inside the handle 1 drives the eccentric shaft 8 to rotate. After the mounting bracket 2 is installed at the top end of the handle 1, the eccentric shaft 8 passes through the mounting bracket 2 and rotates inside the mounting bracket 2 under the connection of the bearing 801, thereby stably shearing hair.

[0032] In this embodiment, the implementation scenario is specifically as follows: When performing preoperative skin preparation, first install the mounting bracket 2 at the top of the handle 1. After passing its center through the eccentric shaft 8, sleeve it on the top of the handle 1 through multiple positioning strips 201, so that the clamping protrusions 202 at the bottom of the multiple positioning strips 201 are clamped into the inner side of the clamping groove 203, thereby fixing the mounting bracket 2. Subsequently, by pulling the mounting bracket 2, the clamping protrusions 202 can be removed from the inner side of the clamping groove 203 for disassembly, and then it is convenient to disinfect the mounting bracket 2. When using the fixed cutter head 3 and the movable cutter head 5, install the fixed cutter head 3 at the top of the mounting bracket 2. First, pinch the two sliding rods 401 so that the two clamping blocks 402 move relatively inside the movable groove 404. Subsequently, after installing the fixed cutter head 3 at the top of the mounting bracket 2, release the sliding rods 401. Under the reset of the spring 403, the clamping blocks 402 are clamped into the inner side of the clamping groove 405, thus facilitating the disassembly and assembly of the fixed cutter head 3. The motor inside the handle 1 drives the eccentric shaft 8 to rotate. Under the rotation of the eccentric shaft 8, the movable tool rest 6 will be driven to move left and right, thereby driving the movable cutter head 5 to move left and right to shear the hair. When the movable cutter head 5 moves left and right, the movable cutter head 5 is always reset to the middle position by the reset elastic frame 7, so that the movable cutter head 5 can continuously move left and right to shear the hair. After the hair clipper completes preoperative skin preparation, release the fixation of the fixed cutter head 3 and then replace the fixed cutter head 3 and the movable cutter head 5 together. Subsequently, disinfect the mounting bracket 2. The entire operation process is simple and convenient. Compared with the existing hair clippers, the present utility model designs a convenient way to replace the disposable cutter head, thereby avoiding the risk of cross-infection.

[0033] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
