[0074] The positioning head 310 is connected and fixed to the socket head 240, and the detachable setting can ensure the normal replacement of the blade 500 and ensure the stability of the blade 500 during use;

[0075] The installation through hole 320 provides a space for the installation of the blade 500 and enables the blade 500 to rotate normally.

[0076] In some embodiments of the present invention, referring to Figure 2 As shown, a plug-in rod 510 is detachably fixedly mounted on the top of the blade 500 , and the plug-in rod 510 can be rotated upward to pass through the mounting through hole 320 .

[0077] The arrangement of the plug-in rod 510 and the matching of the mounting through hole 320 can ensure the position of the blade 500 relative to the positioning head 310, and can drive the blade 500 to rotate normally to adjust the angle under the action of external force.

[0078] In some embodiments of the present invention, referring to Figure 2 As shown, the drive assembly 400 includes:

[0079] A threaded column 410, the threaded column 410 can rotatably pass through the threaded through hole 120;

[0080] A pressing plate 420, which is detachably fixed to the top of the threaded column 410 and drives the pulling arm 210 to rotate when it is lifted or lowered;

[0082] The threaded column 410 can slide up and down through the thread when rotating, and drive the pressing plate 420 to adjust its position when sliding up and down;

[0083] The pressing plate 420 is set to press the clamping plate 220 by descending, thereby limiting the rotation angle of the clamping plate 220 to determine the maximum opening angle of the pulling arm 210;

[0084] The setting of the knob 430 makes it convenient to apply external force to the threaded column 410, so that medical staff can drive the threaded column 410 to rotate.

[0085] Working method of the utility model:

[0086] When replacing the blade 500, the bolts between the socket 240 and the positioning head 310 are removed and separated, and then the blade 500 is replaced, and the replaced positioning head 310 is inserted into the socket 240 and fixed by bolts;

[0087] When adjusting the angle of the blade 500, a rotational force is applied to the plug-in rod 510, so that the plug-in rod 510 drives the blade 500 to rotate and adjust the angle;

[0088] When adjusting the opening distance of the traction grip 320, rotate the threaded column 410, and the threaded column 410 drives the pressure plate 420 to rise and fall under the action of the thread (the pressure plate 420 reduces the opening distance of the traction grip 320 when it descends, and increases the opening distance of the traction grip 320 when it rises), and the coil spring 250 will drive the traction grip 320 to open through the traction arm 210 (the coil spring 250 always remains in the stored power state).
