[0036] Specifically, when using the adjustable charging speed electric clipper charger, first, the size of the current can be adjusted by pressing the adjustment button 3. When the adjustment button 3 is pressed, the increase pin of the microcontroller will detect a low-level signal. The microcontroller recognizes this signal through programming, then increases the duty cycle of the pulse width modulation corresponding to the charging current, thereby increasing the charging speed. Correspondingly, when the current needs to be reduced, the microcontroller will reduce the duty cycle of the pulse width modulation corresponding to the charging current, thereby slowing down the charging speed. In addition, the size of the charging current can be displayed in real time through the display screen 2, enabling the user to intuitively understand the current charging status, achieving the effect of accurately adjusting the charging speed of the electric clipper. When winding the connecting line 16, the user can rotate the turntable 14 to achieve this. The turntable 14 will drive the rotating column 9 on one side to rotate when it is under stress. When the rotating column 9 rotates, the coil 15 and the ratchet wheel 8 on its outer wall will also rotate. With the rotation of the coil 15, the connecting line 16 will be wound on its outer wall, thereby achieving the winding of the connecting line 16. When rotating the turntable 14 clockwise, the user can pull the tab 10, which will drive the first clamping plate 13 to rotate, causing the teeth on one side of the first clamping plate 13 to be clamped on the outer wall of the ratchet wheel 8, preventing the turntable 14 from reversing. When reverse rotation is needed, the user can pull the tab 10 to the other side, causing the teeth previously clamped on the ratchet wheel 8 to disengage, and clamping the teeth on the other side on the outer wall of the ratchet wheel 8, thereby achieving reverse locking. To further lock the first clamping plate 13, the user only needs to clamp the slot at the top of the first clamping plate 13 on the outer wall of the clamping ball 12. The clamping ball 12, through the pushing force provided by the first spring 11, can stably clamp the first clamping plate 13, preventing the ratchet wheel 8 from rotating, ensuring that the connecting line 16 does not fall off during winding, achieving the effect of preventing the connecting line 16 from loosening.

[0037] Referring to Figure 1 , Figure 4 and Figure 5The inner wall of the shell 1 is fixedly connected with a clamping groove 21, and the outer wall of the shell 1 is provided with a heat dissipation fin 6 made of high-thermal-conductivity aluminum alloy and having excellent heat conduction performance, which can quickly dissipate the heat generated inside the charger to the outside, effectively reduce the working temperature of the equipment, prolong the service life, and the inner wall of the heat dissipation fin 6 is slidably connected with a connecting column 18 made of stainless steel and having high hardness, corrosion resistance and wear resistance, which can maintain stable mechanical properties during frequent sliding and rotating, the bottom of the connecting column 18 is rotatably connected to the top of the heat dissipation fin 6, the outer wall of the connecting column 18 is rotatably connected to the inside of the heat dissipation fin 6, the outer wall of the connecting column 18 is fixedly connected with a handle 17 made of high-strength nylon material and having excellent wear resistance and tensile strength, which can withstand frequent pulling operation without being easily damaged, while providing a comfortable operation feeling, the outer wall of the connecting column 18 is slidably connected to the inside of the heat dissipation fin 6, the outer wall of the connecting column 18 is provided with a second spring 19, one end of the second spring 19 is fixedly connected to the bottom of the heat dissipation fin 6, the other end of the second spring 19 is fixedly connected with a second clamping plate 20 made of zinc alloy material and having high strength and corrosion resistance, which can withstand large mechanical stress to ensure stable sliding and locking in the clamping groove 21, the side wall of the second clamping plate 20 is rotatably connected to the inner wall of the clamping groove 21, and the side wall of the second clamping plate 20 is slidably connected to the inner wall of the clamping groove 21.

[0038] Specifically, when adjusting the heat dissipation fin 6, the handle 17 needs to be pulled first, and the movement of the handle 17 will drive the internal connecting column 18 to slide. When the connecting column 18 is retracted, the second spring 19 on the outer wall thereof will also be retracted, thereby providing elastic support for the movement of the connecting column 18. With the movement of the connecting column 18, the second clamping plate 20 will be abutted against the inner wall of the clamping groove 21 to ensure that the heat dissipation fin 6 remains stable during normal use. When it is necessary to add or reduce the heat dissipation fin 6, the user can rotate the handle 17 while pulling it. By rotating the handle 17, the connected second clamping plate 20 will change from horizontal to vertical, thereby causing it to be separated from the inner wall of the clamping groove 21. Once the second clamping plate 20 is separated from the clamping groove 21, the user can pull out the second clamping plate 20, thereby increasing or reducing the heat dissipation fin 6, making the disassembly and installation of the heat dissipation fin 6 simple and fast, and the user can flexibly adjust the number of heat dissipation fins 6 according to actual needs to achieve the best heat dissipation effect. The increase and decrease of the heat dissipation fin 6 is very convenient, which not only ensures the stability of the heat dissipation system, but also improves the user experience, not only improves the heat dissipation efficiency of the equipment, but also enhances the adaptability and maintenance convenience of the equipment.

[0039] Working principle: when using the adjustable charging speed electric clipper charger, first, the size of the current can be adjusted by pressing the adjustment button 3, and at the same time, the increase pin of the microcontroller detects the low level signal, then the microcontroller identifies the signal by programming, and increases the duty cycle of the pulse width modulation corresponding to the charging current, and when reducing the current, the duty cycle of the pulse width modulation corresponding to the charging current is reduced, and the size of the current can be displayed on the display screen 2, achieving the effect of adjusting the charging speed of the electric clipper.

[0040] Then when winding the connecting wire 16, rotate the rotating disc 14, and the rotating disc 14 drives the rotating column 9 on one side to rotate, and then the rotating column 9 rotates the coil 15 and the ratchet wheel 8 on the outer wall, and then the connecting wire 16 is wound on the outer wall after the coil 15 rotates, and in this process, when rotating clockwise, pull the paddle 10, and the first clamping plate 13 is rotated and the teeth on one side of the first clamping plate 13 are clamped on the outer wall of the ratchet wheel 8, and then when rotating counterclockwise, pull the paddle 10 to the other side, so that the teeth on the previous side are separated from the ratchet wheel 8, and the teeth on the other side are clamped on the outer wall of the ratchet wheel 8, and when locking the first clamping plate 13, only need to clamp the slot at the top of the first clamping plate 13 on the outer wall of the clamping ball 12, and the clamping ball 12 provides a pushing force through the first spring 11 to stably clamp the first clamping plate 13, achieving the effect of preventing the connecting wire 16 from falling off.

[0041] Then when adjusting the cooling fins 6, first pull the handle 17 to drive the connecting column 18 inside to slide, then the connecting column 18 will shrink the second spring 19 on the outer wall when shrinking, and then the movement of the connecting column 18 will make the second clamping plate 20 abut against the inner wall of the clamping groove 21, and then when adding the cooling fins 6, pull the handle 17 while rotating it, which can rotate the connected second clamping plate 20, so that it changes from horizontal to vertical, so that it can be separated from the inner wall of the clamping groove 21, and then the second clamping plate 20 can be pulled out, so that the cooling fins 6 can be increased or decreased, achieving the effect of disassembling the cooling fins 6.
