When the inner and outer blades of the hair follicle extracting head are simultaneously sharpened, the cutter-retracting groove 220 can polish the edge portion of the end of the hair follicle extracting head, thereby ensuring sharpness of the edge of the hair follicle extracting head.

In this embodiment, the sander body is provided with a mounting hole 400; the mounting hole 400 is used to connect a high pressure spray head.

Specifically, the inner wall of the mounting hole 400 in this embodiment is provided with an internal thread, which is matched with an external thread of the high-pressure nozzle, and the high-pressure nozzle is connected with the mounting hole 400 by means of a threaded connection before polishing the hair follicle extracting head.

When polishing hair follicle extraction head, the high-pressure nozzle can be used for spraying lubricating liquid into the sander main body, so that the hair follicle extraction head is cleaned while achieving the effects of lubrication and cooling, and the influence of scrap iron on the use of the hair follicle extraction head is avoided.

In this embodiment, the sander body is further provided with a liquid outlet 500; the liquid outlet 500 is provided on a face of the sander body remote from the mounting hole 400.

The liquid outlet 500 can discharge the lubricating liquid with the scrap iron after cleaning the hair follicle extraction head from the sander main body, so that the scrap iron residues are prevented from remaining in the sander main body and attaching to the first grinding working surface 210 or the second grinding working surface 310, and the use of the hair follicle extraction head sander is prevented from being influenced.

In this embodiment, the outer blade grinding member 200 is a cylindrical grinding member; the inner wall of the cylindrical grinding piece is a first grinding working surface 210, the diameter of the first grinding working surface 210 is gradually reduced from a cylinder mouth to a cylinder bottom, and the cylinder mouth of the cylindrical grinding piece is a feed port of the outer blade grinding piece 200; the inner blade grinding member 300 is disposed within the outer blade grinding member 200.

Specifically, the cylindrical grinding member in this embodiment has its cylindrical opening facing the positioning hole 100, so that the hair follicle extracting head can directly enter the cylindrical grinding member after extending into the sander body along the positioning hole 100. And, the diameter of first grinding working face 210 is gradually reduced from the nozzle to the barrel bottom, and the outer edge of hair follicle extraction head is in butt joint with first grinding working face 210, and then rotates sander main part or hair follicle extraction head alright realize polishing to the outer edge, and the first grinding working face 210 that encircles hair follicle extraction head a week can evenly polish to the outer edge, avoids the difference of the precision of polishing everywhere of outer edge.

In this embodiment, the inner blade sharpening member 300 is a tapered sharpening member; the outer wall of the conical grinding member is a second grinding face 310, and the diameter of the second grinding face 310 is widened in the direction from the nozzle to the bottom.
