[0024] Specifically, the clamping adjustment assembly 2 includes a servo motor 201. The servo motor 201 is detachably connected to the inner side wall of the support groove 102. One end of a lead screw 202 is connected to the output shaft of the servo motor 201, and the other end of the lead screw 202 is rotatably connected to the inner side wall of the support groove 102.
