[0063] In the above embodiment, the bottom cover 101 is further provided with a mounting groove for mounting the battery 9 , and a shockproof soft glue 10 is provided in the mounting groove.

[0064] It is understandable that a mounting groove is provided on the bottom cover 101 to install the battery 9, and a shockproof soft rubber 10 is provided on the periphery of the battery 9 to prevent the battery 9 from colliding with the bottom cover 101 due to vibration when the hair clipper is running, thereby wearing the bottom cover 101 and damaging the battery 9.

[0065] The shockproof soft rubber 10 may also adopt other structures, such as shockproof gaskets, etc., without limitation, as long as the above-mentioned technical effects can be achieved.

[0066] On the basis of the above-mentioned embodiment, the bottom cover 101 is provided with a charging base, which is fixed to the bottom cover 101 via a power socket pressing plate 11 , and the charging base is connected to the battery 9 .

[0067] It should be noted that the battery 9 of the hair clipper is connected to the power source through the charging stand, so as to charge the battery 9. The charging stand is fixedly mounted on the bottom cover 101 through the power socket pressure plate 11 and tightened by screws. When the hair clipper is running, the battery 9 discharges, so that each component on the circuit board 2 is powered on and started. When the battery 9 is out of power, the battery 9 is charged through the cooperation of the power source and the charging stand to ensure the next operation of the hair clipper.

[0068] Optionally, the battery 9 may also be a non-rechargeable battery.

[0069] In the above embodiment, a motor 12 is provided on the circuit board 2 , and an output end of the motor 12 is connected to the cutter head assembly 132 .

[0070] It is understandable that the circuit board 2 is powered on by the switch 3 to start the motor 12, and the motor 12 drives the cutter head assembly 132 13 to start, thereby trimming the hair.

[0071] As a preferred embodiment, the cutter head assembly 132 includes a cutter head seat 131 and a cutter head assembly 132 . The cutter head seat 131 is connected to the output end of the motor 12 , and the cutter head assembly 132 is disposed on the cutter head seat 131 .

[0072] It should be noted that the cutter head assembly 132 includes a fixed cutter and a movable cutter. The fixed cutter is fixed to the cutter head seat 131 through a fixed cutter holder. The movable cutter is movably arranged on the fixed cutter holder through a movable cutter holder. The movable cutter can perform horizontal shearing motion relative to the fixed cutter with the movable cutter holder. The front ends of the movable cutter and the fixed cutter are both provided with cutter teeth. The cutter teeth of the movable cutter are retracted relative to the cutter teeth of the fixed cutter. The fixed cutter holder is provided with an isolation structure for separating the cutter teeth of the fixed cutter from the skin. The isolation structure is provided with a plurality of gaps or notches for hair to pass through the fixed cutter and the movable cutter. The adjacent gaps or notches are spaced apart. The motor 12 is operated to drive the movable cutter holder on the cutter head seat 131 to move, thereby driving the movable cutter to perform horizontal shearing motion relative to the fixed cutter to achieve hair trimming.

[0073] In the above situation, a cutter head adjustment rod 133 connected to the cutter head group 132 is provided on one side of the bottom cover 101. The cutter head adjustment rod 133 is L-shaped. The cutter head adjustment rod 133 includes a long rod and a short rod arranged vertically. The long rod of the cutter head adjustment rod 133 is a hand-held part, which is located on one side of the bottom cover 101. The short rod of the cutter head adjustment rod 133 is a transmission part, which is connected to one side of the moving knife holder. The cutter head adjustment rod 133 is used to adjust the distance between the moving knife and the fixed knife of the cutter head group 132.

[0074] It is understandable that the distance between the cutter head assembly 132 and the scalp during the haircutting process can be controlled by adjusting the cutter head adjustment rod 133 to trim hair styles of different lengths.

[0075] Furthermore, the short rod of the cutter head adjustment rod 133 is connected to one side of the movable cutter holder, and the distance between the movable cutter and the fixed cutter is adjusted by rotating the long rod of the cutter head adjustment rod 133 up and down to control the length of the hair trimmed each time.

[0076] In the above embodiment, the bottom cover 101 is an aluminum alloy cover.

[0077] It should be noted that, in the present embodiment, the bottom cover 101 is an aluminum alloy cover, but in practical applications, there is no limitation on the material of the bottom cover 101 .

[0078] In summary, the utility model provides a hair clipper that is easy to adjust the speed with one hand. In the first step, the switch 3, the motor 12 and the battery 9 are welded to the circuit board 2. In the second step, the panel decoration, the lens 7 and the display screen 6 are installed on the surface cover 103 and the inner bottom cover 102 in sequence. In the third step, the shockproof soft rubber 10 is installed on the bottom cover 101, and the semi-finished product installed in the first step is installed on the semi-finished product completed in the third step, and then the semi-finished product completed in the second step is installed. In the fourth step, the completed semi-finished product is installed on the cutter head group 132 pieces 13 and the screws are tightened. After the whole machine is assembled, try to turn on the switch 3, manually adjust the scroll wheel 5 for controlling the speed, observe the changes in the numbers on the display screen 6, and observe whether the cutter head has an obvious fast and slow rhythm.

[0079] When in use, turn on the switch 3, the whole machine starts to work, and the display screen 6 displays various parameters. When the scroll wheel 5 is rolled up and down, the speed icon on the display screen 6 changes significantly, and the speed sound of the motor 12 can be clearly felt by the human body, and the shearing speed of the cutter head group 132 can also be felt. The whole process depends on the scroll wheel 5 rolling up and down, and when rolling, the resistance of the encoder 4 on the circuit board 2 changes, so that the current output from the circuit board 2 to the motor 12 has a size to control the speed of the motor 12. The device has a simple structure, is easy to operate, and has strong practicality.
