[0045] In the present application, in order to facilitate the reset spring in the auxiliary spring sleeve 23, an airbag 16 is arranged between the top plate 9 and the bottom plate 1. The airbag 16 can undergo elastic deformation after being subjected to the downward pressure of the top plate 9, and then provide a certain damping effect for the descent of the top plate 9 to avoid descent too fast. At the same time, after the force applied to the top plate 9 disappears, the airbag 16 can slowly restore its own deformation under the action of its own elastic material. The airbag 16 has an air inlet nozzle and an air outlet nozzle, and the air inlet nozzle and the air outlet nozzle can allow the exchange between the internal gas of the airbag 16 and the external gas when the airbag 16 is deformed. In the present application, the airbag 16 is matched with a pressure plate 19, which has a honeycomb through hole running through it, and the cross section of the honeycomb through hole is a regular hexagon or other regular polygon structure. The function of the pressure plate 19 is to ensure the stable contact between the top plate 9 and the airbag 16.

[0046] In the present application, the top plate plug-in part 7 is composed of two horizontally placed U-shaped plates with openings facing each other. The bottom ends of the two U-shaped plates are fixed to the top plate 9 through connecting plates. The top plate plug-in part 7 forms a chamber inside for the shell telescopic part 6 to be plugged in. The top plate plug-in part 7 is connected at the top and bottom ends of the port away from the top plate 9 by connecting plates respectively.

[0047] The end of the telescopic shell part 6 inserted into the top plate plug-in part 7 is provided with an adjustment handle 8 , and the adjustment handle 8 can adjust the length of the telescopic shell part 6 in the top plate plug-in part 7 .

[0048] The housing telescopic portion 6 may be provided with a PCB board and a battery for controlling the lighting of the fill light 25. The battery is electrically connected to the fill light 25 through the control circuit of the PCB board to switch the fill light 25 on and off. In the present application, after the adjustment handle 8 is screwed out of the housing telescopic portion 6 through the threaded structure, the housing telescopic portion 6 can be pulled out from the top plate plug-in portion 7, and the dermatologist can examine the rest of the area except the arm by holding the device.

[0049] Finally, although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
