[0002] The hair burr is a tool specially used in the field of hair transplantation. Its special design and structure enable it to extract hair follicles without shaving, providing a new solution for hair transplantation surgery.

[0003] Chinese Patent: CN215129701U discloses a drill for growing hair without shaving, comprising a drill body, the output end of which is connected to a long hair extraction needle. The long hair extraction needle is provided with a plurality of slots extending from its front end along its length, wherein the length of the slots is less than the length of the long hair extraction needle, and there is a gap between two adjacent slots. This utility model utilizes a needle-shaped drill with slots to extract long hair, and can extract long hair follicles with a hair shaft length of 6 cm without shaving the head, without shaving the surrounding native hair. After hair transplantation, the hair density on the back of the head is uniform, and the transplanted area immediately produces long hair with a hair shaft length of 6 cm, without leaving any traces of hair transplantation. This can well protect the privacy of the transplant recipient, while achieving a more beautiful and natural effect.

[0004] Although the above patent can achieve the goal of leaving no traces of hair transplantation and can well protect the privacy of the transplant recipient while achieving a more beautiful and natural effect, its double-grooved needle is always exposed to the external environment, which makes it easy for the operator's hand to be pricked by the needle when picking up or carrying it. In addition, if the drill falls, the needle is easily damaged due to contact with the ground, and the needle in the prior art is not easy to remove and replace. Therefore, it is necessary to design a completely non-shaving ultra-fine soft long hair drill to solve the above problems. Utility Model Content

[0005] The purpose of the present invention is to provide a completely non-shaving ultra-fine soft long hair drill to solve the problems raised by the above-mentioned background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a completely non-shaving ultra-fine, soft, long hair drill, comprising a handle, a linkage groove formed on the surface of the handle, a fixed cylinder slidably connected to the interior of the linkage groove, a needle slidably connected to the surface of the fixed cylinder through an opening, and a limit sleeve fixedly mounted on the rear surface of the needle;

[0007] Slide grooves are provided on both sides of the front part of the inner cavity of the fixed cylinder, and a slider is slidably connected to the inside of the slide groove. A traction plate is fixedly installed on the rear of the slider, and a limit block is fixedly installed on one side of the traction plate. One side of the limit block passes through the fixed cylinder and the handle in sequence and extends to the outside of the handle. A tightening mechanism is provided on one side of the traction plate, and a swivel is slidably connected to the surface of the handle through a groove, and a traction ring is fixedly installed on the surface of the swivel, and the top and bottom of the traction ring are slidably connected to a pressure block through an opening.

[0010] Preferably, a receiving groove for use with a needle is provided on the rear side of the inner cavity of the linkage groove.

[0011] Preferably, fill lights are fixedly installed above and below the surface of the fixed cylinder.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The ultra-fine, soft, and long-hair drill that does not require shaving at all, rotates the traction ring, which drives the pressure block to move. When the pressure block moves to contact the limit block, the two limit blocks can be pushed toward the middle at the same time. Finally, by pressing the two pressure blocks, the pressure block pushes the limit block to the inner side of the handle. At this time, the fixed cylinder stops being limited. The operator can pull the fixed cylinder forward to disengage the fixed cylinder from the handle, thereby achieving the effect of facilitating the removal and replacement of the needle. In addition, the provision of the traction ring and the pressure block makes it easier for the operator to press the limit block, thereby improving the efficiency of replacing the needle.

[0014] 2. This ultra-fine, soft, long hair drill that does not shave at all, is designed by inserting the needle into the receiving slot and then inserting the fixed cylinder into the linkage slot. At this time, the fixed cylinder drives the limit block to move to the inner side of the linkage slot. When the limit block moves to the movable opening, it can be pushed out by the elastic force of the spring. After being pushed out, the limit block can limit and fix the fixed cylinder. At the same time, after the fixed cylinder moves into the linkage slot, the front side of the inner cavity of the fixed cylinder can be tightly attached to the limit sleeve, thereby achieving the effect of sealing and protecting the needle and preventing the needle from pricking the staff.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1

[0023] Please refer to Figure 1-5 As shown, the utility model provides a completely non-shaving ultra-fine soft long hair drill, comprising a handle 1, a linkage groove 2 being formed on the surface of the handle 1, a fixed cylinder 3 being slidably connected to the interior of the linkage groove 2, the surface of the fixed cylinder 3 being made of rubber and having an interference fit with the inner wall of the linkage groove 2, a needle 4 being slidably connected to the surface of the fixed cylinder 3 through an opening, a limit sleeve 5 being fixedly mounted on the rear portion of the surface of the needle 4, the rear portion of the limit sleeve 5 being made of rubber;

[0024] Specifically, both sides of the front part of the inner cavity of the fixed cylinder 3 are provided with slide grooves 6, and the inner part of the slide grooves 6 is slidably connected to the slider 7. The rear of the slider 7 is fixedly installed with a traction plate 8. A limit block 9 is fixedly installed on one side of the traction plate 8. The rear side of the limit block 9 is set to an inclined surface. One side of the limit block 9 sequentially passes through the fixed cylinder 3 and the grip 1 and extends to the outside of the grip 1. A tightening mechanism is provided on one side of the traction plate 8. The tightening mechanism includes a spring 10 welded to one side of the traction plate 8. One end of the spring 10 is fixedly connected to the front side of the inner cavity of the fixed cylinder 3 through a bracket. Both sides of the grip 1 and the fixed cylinder 3 are provided with movable openings 11 for use with the limit block 9. The rear side of the inner cavity of the linkage groove 2 is provided with a storage groove 12 for use with the needle 4. By setting the limit block 9 and pressing the two limit blocks After the limit block 9 is pushed out, the fixed cylinder 3 can be limited and fixed. At the same time, after the fixed cylinder 3 moves into the linkage groove 2, the front side of the inner cavity of the fixed cylinder 3 can be tightly attached to the limiting sleeve 5, thereby achieving the effect of sealing and protecting the needle 4 and avoiding the needle 4 from stabbing the staff.

[0025] Specifically, the surface of the handle 1 is slidably connected to a swivel 14 through a groove, and a traction ring 15 is fixedly installed on the surface of the swivel 14. The top and bottom of the traction ring 15 are slidably connected to a pressure block 16 through an opening. The inner side of the swivel 14 is set to a rubber material and has an interference fit with the groove on the surface of the handle 1. By providing the traction ring 15 and the pressure block 16, it is convenient for the operator to press the limit block 9, thereby improving the efficiency of replacing the needle 4.

[0026] Among them, fill lights 13 are fixedly installed above and below the surface of the fixed tube 3. By setting the fill light 13 and turning on the fill light 13, fill light can be provided to the top of the person's head, making it more convenient for the operator to observe the top of the person's head.

[0027] Working principle: The utility model is a completely non-shaving ultra-fine soft long hair drill. By setting a fill light 13 and turning on the fill light 13, the top of the person's head can be filled with light, which makes it more convenient for the operator to observe the top of the person's head. When the needle 4 needs to be replaced, the traction ring 15 can be rotated. The rotation of the traction ring 15 drives the pressure block 16 to move. When the pressure block 16 moves to contact the limit block 9, the two limit blocks 9 can be pushed to the middle at the same time. Finally, by pressing the two pressure blocks 16, the pressure block 16 pushes the limit block 9 to the inner side of the handle 1. At this time, the fixed cylinder 3 stops being limited. The operator can pull the fixed cylinder 3 forward to disengage the fixed cylinder 3 from the handle 1, thereby facilitating the removal of the needle 4. In addition to the replacement effect, the provision of the traction ring 15 and the pressure block 16 makes it easier for the operator to press the limit block 9, thereby improving the efficiency of replacing the needle 4. When the device needs to be carried, the needle 4 can be inserted into the storage groove 12, and then the fixed cylinder 3 is inserted into the linkage groove 2. At this time, the fixed cylinder 3 drives the limit block 9 to move to the inner side of the linkage groove 2. When the limit block 9 moves to the movable opening 11, it can be pushed out by the elastic force of the spring 10. After the limit block 9 is pushed out, the fixed cylinder 3 can be limited and fixed. At the same time, after the fixed cylinder 3 moves into the linkage groove 2, the front side of the inner cavity of the fixed cylinder 3 can be tightly attached to the limit sleeve 5, thereby achieving the effect of sealing and protecting the needle 4, and avoiding the situation where the needle 4 injures the staff.
