[0010] Specifically, a gasket is installed in the frame groove.

[0011] By adopting the above technical scheme, the gasket in the frame groove can limit the frame block, so that the frame block can stably displace in the frame groove, and the frame block will not be excessively displaced, so that the subsequent rail can be conveniently disassembled.

[0012] Specifically, a wire hole is formed in the rail, and a rubber pad is bonded to the outer wall surface of the handle.

[0013] By adopting the above technical scheme, the rubber pad has good elasticity, so that the person can more conveniently pull the handle, and the handle can be conveniently disassembled.

[0014] Specifically, a sliding groove is formed in the outer wall surface of the rail and the outer wall surface of the plug.

[0015] By adopting the above technical scheme, the sliding grooves on the outer periphery of the rail and the plug are matched with the protrusions in the square seat or the handle, so that the stability of the rail and the plug after installation can be improved.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1、The technical scheme of the application can adjust the distance between the handle and the clamping head by pulling the square seat outside the handle, making the square seat drive the rail to extend from the handle and move the clamping head, so as to facilitate the use of the bipolar coagulation forceps.

[0018] 2、The technical scheme of the application can adjust the distance between the handle and the clamping head by pulling the square seat outside the handle, making the square seat drive the rail to extend from the handle and move the clamping head, so as to facilitate the use of the bipolar coagulation forceps.
