The insert block 32 can be inserted into the first limiting rod 23, and the cutter head 3 can achieve multi-point support and be more stable. The bottom of the cutter head 3 is connected to a mounting block 4, which can be inserted into the first limiting groove 22. The hair clipper body 1 is installed inside There is an installation box 6, and a second connecting rod 61 is connected to one side of the installation box 6. The second connecting rod 61 is movably connected to the first limit block 5, and one side of the first limit block 5 is fixedly connected to the first connecting rod 51. The knob 54 is gently pressed to make the third connecting rod 64 drive the insertion rod 66 to move to the nearest point of the slide groove 63. At this time, the first spring 65 restores the elastic force, so that the second connecting rod 61 pushes the first limit block 5 to move forward until the first limit block 5 is in contact with the second limit groove 41, so that the installation block 4 cannot move, and the installation is completed.

[0034] See also Figure 1 - Figure 2 A knob 54 is installed at one end of the first connecting rod 51, and a second limiting rod 52 is fixedly connected to one side of the first limiting block 5. The knob 54 can rotate the second limiting rod 52 outside the hair clipper body 1 to unlock the fixed component inside the hair clipper body 1.

[0035] See also Figure 4 and Figure 5 An arc-shaped opening 42 is provided at the bottom of the mounting block 4, and the arc-shaped opening 42 coincides with the arc of the first connecting rod 51. A second limiting groove 41 is provided on one side of the mounting block 4, and a third limiting groove 43 is provided on one side of the second limiting groove 41. The arc-shaped opening 42 and the third limiting groove 43 are connected. When the cutter head 3 reaches a position flush with the mounting base 2, the arc-shaped opening 42 at the bottom of the mounting block 4 can be fitted with the first connecting rod 51, and the second limiting rod 52 can vertically enter the third limiting groove 43. The knob 54 is rotated 90° to fix the mounting block 4. Finally, the first limiting block 5 is snapped into the second limiting groove 41 to fix the knob 54.

[0036] See also Figure 4 and Figure 5 A second limit block 62 is installed inside the installation box 6, and a slide groove 63 is provided on one side of the second limit block 62.

The insert rod 66 limits the third connecting rod 64 to move within the range of the slide groove 63. Pressing the knob 54 can utilize the irregular shape of the slide groove 63. When the insert rod 66 is at the farthest point, the knob 54 can be limited to the installation position. Pressing the knob 54 again, the insert rod 66 will move to the nearest point, and the knob 54 can be restored to the locked position.

[0037] See also Figure 4 - Figure 6 A mounting plate 7 is installed inside the hair clipper body 1, and a second spring 71 is installed above the mounting plate 7. When the fixing component inside the hair clipper body 1 is unlocked, the second spring 71 can bounce the cutter head 3 upward, and the cutter head 3 is naturally separated from the mounting base 2, making it convenient to take the cutter head 3.

[0038] See also Figure 1 and Figure 2 A hole 101 is opened on one side of the hair clipper body 1, and a shielding plate 53 is installed inside the hole 101. Broken hair can easily fall into the interior of the hair clipper body 1 through the hole 101. The shielding plate 53 can completely block the hole 101, so that broken hair will not enter the interior of the hair clipper body 1.

[0039] See also Figure 4 and Figure 5 A third connecting rod 64 is installed on one side of the mounting box 6, and a first spring 65 is installed inside the mounting box 6. When the knob 54 is pressed, the contraction and extension of the first spring 65 can be used to realize the natural rebound of the knob 54. The third connecting rod 64 can limit the telescopic distance of the knob 54, and will not cause the knob 54 to exceed the outer wall of the hair clipper body 1, nor will it cause the knob 54 to sink into the interior of the hair clipper body 1, which is convenient to use.

[0040] The working principle of the present utility model is as follows: when the cutter head 3 needs to be disassembled, the knob 54 is pressed to make the first connecting rod 51 push the first limit block 5 to move backward, so that the first limit block 5 and the mounting block 4 are completely separated, and then the first limit block 5 pushes the second limit block 62 to squeeze the first spring 65, and then the knob 54 is rotated 90° to make the second limit rod 52 move to a vertical position in the third limit groove 43. At this time, the mounting block 4 loses its restriction, and the second spring 71 restores the elastic force to push the mounting block 4 upward, so that the cutter head 3 moves vertically upward until the second spring 71 is stable. At this time, the cutter head 3 exceeds the surface of the mounting base 2. Pinch the two sides of the cutter head 3 with your hands to take out the cutter head 3, and the disassembly is completed.

[0041] When the cutter head 3 needs to be installed, the knob 54 needs to be kept in a pressed state. Since the groove 63 on the second limit block 62 is an irregular shape, the insertion rod 66 can stay at the farthest point of the groove 63, so that the first spring 65 remains in a compressed state, so that the second connecting rod 61 connected to one end of the second limit block 62 will pull the first limit block 5 to a state separated from the mounting block 4, and then the mounting block 4 installed at the bottom of the cutter head 3 is inserted into the first limit groove 22 opened on the fixing plate 21 until the arc-shaped opening 42 is in contact with the first connecting rod 51. At this time, the second limit rod 52 also enters the third limit groove 43, and then the knob 54 is rotated 90° to move the second limit rod 52 to a horizontal position.

[0042] Finally, gently press the knob 54 so that the third connecting rod 64 drives the insertion rod 66 to move to the nearest point of the slide groove 63. At this time, the first spring 65 restores its elastic force, causing the second connecting rod 61 to push the first limit block 5 forward until the first limit block 5 is in contact with the second limit groove 41, so that the installation block 4 cannot move, and the installation is completed.
