[0029] When the angle of the carrier 10 is adjusted, in the initial state, the adjusting gap 17 is left between the sealing cover 15 and the inner wall of the through slot, at this time, the manual rotation of the carrier 10 can drive the whole angle adjusting assembly to rotate, after the adjustment is completed, the hand holding the carrier 10 is not released, and the other hand pushes the push rod 18 into the sleeve 14, the limiting assembly is compressed and deformed, the adjusting gap 17 is filled, the sealing cover 15 is pressed against the inner side wall of the sleeve 14 and the lower support 7, and the side plate 16 is tightly abutted against the end face of the connecting rod 13, at this time, the rotation of the whole formed by the connection of the angle adjusting assembly and the carrier 10 must overcome the frictional resistance between the sealing cover 15 and the inner side wall of the lower support 7, so as to realize the effect of fixing the angle of the carrier 10, and when disassembled, the push rod 18 can be pulled out.

[0030] Preferably, the upper support 6 and the telescopic rod 5 are connected through another angle adjusting assembly, and the central axes of the two angle adjusting assemblies are vertically distributed in space, which further widens the adjustable range of the angle of the retractor 19, so that the retractor 19 can be oriented to pull the skin layer according to the operation requirement, thereby expanding the operation space.

[0031] Preferably, the carrier 10 is provided with a clamping groove 12 for clamping the retractor 19, and the clamping groove 12 is in a U-shaped structure matched with the existing retractor 19.

[0032] Preferably, the carrier 10 is provided with an adhesive bandage 11 for wrapping and fixing the retractor 19 and the carrier 10, the bandage 11 can press the retractor 19 in the clamping groove 12, further improving the connection stability between the carrier 10 and the retractor 19, and facilitating disassembly and assembly.

[0033] Preferably, the rod structure includes a taper rod 3 and a straight rod 4 arranged on the taper rod 3, and the mounting seat 1 is provided with a placing seat 2 matched with the taper rod 3, the rod structure can be fixed by being placed into the placing seat 2 from top to bottom, and the orientation of the telescopic rod 5 can be adjusted at any time by picking up the rod structure and placing it down, which is convenient, efficient and stable.

[0034] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the present application. It should be noted that, for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
