Technical Field
[0001] This utility model relates to the field of electric clipper heads, specifically an electric clipper head adjustment device. Background Technology
[0002] Electric hair clippers are a common tool in beauty salons and are familiar to the public when getting haircuts. Currently, a few electric hair clippers lack a blade adjustment mechanism to limit the length of hair cut. However, most rechargeable electric hair clippers are equipped with a blade adjustment mechanism, allowing adjustment of the relative position of the moving and stationary blades to control the length of hair left after cutting. Traditional electric hair clippers primarily have an adjustment mechanism built into the body, containing a push rod that works in conjunction with the moving blade. During use, pushing a key on the outside of the casing moves the push rod, driving the moving blade back and forth, thus adjusting its position.
[0003] This can lead to inaccurate gear selection, difficulty in judging whether the gear is slipping, and a lack of gear feel. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an electric clipper head adjustment device to solve the problems mentioned in the background art, such as inaccurate gear selection, difficulty in determining whether the gear is slipping, and lack of gear selection feel.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an electric clipper head adjustment device, comprising a carbon steel clipper head and a base, a connecting seat fixedly mounted on the outer surface of the base, an adjustment knob rotatably connected to the outer surface of the connecting seat, a small worm gear fixedly mounted on the outer surface of the adjustment knob, a large worm gear meshing with the outer surface of the small worm gear, a slider provided on the outer surface of the large worm gear, the outer surface of the slider slidingly connected to the outer surface of the connecting seat, the outer surface of the slider fixedly connected to the carbon steel clipper head, a plurality of through holes being formed on the outer surface of the carbon steel clipper head, a fixing member fixedly mounted on the base through the through holes, a connecting member fixedly mounted on the outer surface of the fixing member, and the hollowed-out clipper head being disposed on the outer surface of the limiting member.
[0006] Preferably, the hollow cutter head is slidably connected to the carbon steel cutter head, a mounting base is fixedly installed on the outer surface of the hollow cutter head, a mounting bolt is provided on the outer surface of the mounting base, the hollow cutter head and the connecting member are fixedly connected by the mounting bolt, a limiting member is fixedly installed on the outer surface of the connecting member, an eccentric shaft is rotatably connected to the outer surface of the limiting member, a spring is fixedly installed on the outer surface of the connecting member, and the other end of the spring away from the connecting member is fixedly connected to the base through the through hole.
[0007] Preferably, the slider is rectangular, and the outer surface of the adjustment knob is provided with a gear position mark.
[0008] Preferably, the spring is disposed on both sides of the limiting seat, and the connecting member is made of plastic.
[0009] Compared with the prior art, the beneficial effects of this utility model are:
[0010] 1. The electric clipper head adjustment device is controlled by rotating the adjustment knob, which drives the small worm gear to rotate in conjunction with the large worm gear. The slider moves back and forth under the constraint of the connecting seat, which drives the carbon steel cutter head fixedly installed on the outer surface of the slider to slide. The staggered distance between the carbon steel cutter head and the hollow cutter head is adjusted, thereby preventing inaccurate gear position, making it easy to judge whether the gear is slipping, and providing a gear position feel.

[0018] Example 1:
[0019] Please refer to Figures 1-4.
[0020] An electric clipper head adjustment device includes a carbon steel clipper head 1, a hollowed-out clipper head 2, and a base 15. A connecting seat 10 is fixedly installed on the outer surface of the base 15. An adjustment knob 11 is rotatably connected to the outer surface of the connecting seat 10. A small worm gear 12 is fixedly installed on the outer surface of the adjustment knob 11. A large worm gear 13 is meshed with the outer surface of the small worm gear 12. A slider 14 is provided on the outer surface of the large worm gear 13. The outer surface of the slider 14 is slidably connected to the outer surface of the connecting seat 10. The outer surface of the slider 14 is fixedly connected to the carbon steel clipper head 1. A plurality of through holes 8 are opened on the outer surface of the carbon steel clipper head 1. A fixing member 7 is fixedly installed on the base 15 through the through holes 8. A connecting member 3 is fixedly installed on the outer surface of the fixing member 7. The hollowed-out clipper head 2 is disposed on the outer surface of the limiting member 5.
[0021] Specifically, by controlling the rotation of the adjustment knob 11, the small worm gear 12 is driven to rotate in conjunction with the large worm gear 13. The slider 14 moves back and forth under the constraint of the connecting seat 10, which drives the carbon steel cutter head 1 fixedly installed on the outer surface of the slider 14 to slide. The staggered distance between the carbon steel cutter head 1 and the hollow cutter head 2 is adjusted, thereby preventing inaccurate gear positions, making it easy to judge whether the gear is slipping, and providing a gear position feel.
[0022] In this embodiment: the slider 14 is rectangular, and the outer surface of the adjustment knob 11 is provided with a gear position mark.
[0023] Specifically, because the slider 14 is rectangular, the output motion will not be linear and the rotation will be unstable. The outer surface of the adjustment knob 11 is marked with a gear position. The rotary adjustment dial integrates a tactile feedback gear, which triggers a gear position sound every 45° to ensure the accuracy of the adjustment.
[0024] Working principle: A connecting seat 10 is fixedly installed on the outer surface of the base 15. An adjusting knob 11 is rotatably connected to the outer surface of the connecting seat 10. A small worm gear 12 is fixedly installed on the outer surface of the adjusting knob 11. A large worm gear 13 is meshed with the outer surface of the small worm gear 12. A slider 14 is set on the outer surface of the large worm gear 13. Input end: small worm gear 12, 1 lead, lead t1, pitch diameter D1; Output end: large worm gear 13, 2 leads, lead t2=2t1, pitch diameter D2=2D1. The output moves at a speed of 1 revolution t1. The outer surface of the slider 14 is slidably connected to the outer surface of the connecting seat 10, and the outer surface of the slider 14 is fixedly connected to the carbon steel cutter head 1. The outer surface of the carbon steel cutter head 1 is opened. There are several through holes 8, and because the base 15 is fixedly installed with a fixing member 7 through the through holes 8, a connecting member 3 is fixedly installed on the outer surface of the fixing member 7, and the hollowed-out cutter head 2 is set on the outer surface of the limiting member 5. The control adjustment knob 11 is rotated, which drives the small worm gear 12 to rotate in conjunction with the large worm gear 13. The slider 14 moves back and forth under the restriction of the connecting seat 10, which drives the carbon steel cutter head 1 fixedly installed on the outer surface of the slider 14 to slide, and adjusts the staggered distance between the carbon steel cutter head 1 and the hollowed-out cutter head 2. Compared with related technologies, the electric clipper head adjustment device provided by this utility model has the following beneficial effects: it can prevent inaccurate gear position, facilitate the judgment of whether the gear is slipping, and provide a gear position feel.

A spring 6 is fixedly installed on the outer surface of the connecting piece 3. The other end of the spring 6 away from the connecting piece 3 is fixedly connected to the base 15 through a through hole 8.
[0028] Specifically, the eccentric shaft 4 rotates, and the connecting piece 3 swings left and right under the restriction of the limiting piece 5, so that the carbon steel cutter head 1 and the hollow cutter head 2 slide and alternate for cutting. Moreover, the other end of the spring piece 6 away from the connecting piece 3 is fixedly connected to the base 15 through the through hole 8. The movement of the carbon steel cutter head 1 will not affect the spring piece 6. At the same time, the hollow cutter head 2 and the connecting piece 3 are fixedly connected by the mounting bolts, and the hollow cutter head 2 and the connecting piece 3 can be disassembled and replaced, thereby improving the applicability of the electric clipper head.
[0029] In this embodiment: the spring element 6 is disposed on both sides of the limiting seat, and the connecting element 3 is made of plastic.
[0030] Specifically, because the spring 6 is located on both sides of the limiting seat, the motor-driven eccentric shaft 4 changes from rotational motion to left and right motion under the restriction of the limiting part 5. The spring 6 resets the left and right sliding hollow cutter head 2. Moreover, the connecting part 3 is made of plastic to ensure the stability of the structure when performing left and right vibration operation.
[0031] Working principle: The eccentric shaft 4 rotates, and the connecting piece 3 swings left and right under the restriction of the limiting piece 5, so that the carbon steel cutter head 1 and the hollow cutter head 2 slide and alternate for cutting. The other end of the spring piece 6 away from the connecting piece 3 is fixedly connected to the base 15 through the through hole 8. The movement of the carbon steel cutter head 1 will not affect the spring piece 6. At the same time, the hollow cutter head 2 is slidably connected to the carbon steel cutter head 1.
