[0024] The clamping drive assembly 6 includes a pivot connection assembly inserted in the swing bar hole 9-3 and slidably connected thereto, and also includes a lifting drive member for driving the pivot connection assembly to move longitudinally. The lifting drive member is any one of an electric push rod, a cylinder or a hydraulic cylinder; the extended end of the lifting drive member is connected to the pivot connection assembly through a fisheye joint.

[0025] Furthermore, the above-mentioned pivot connection assembly includes a sliding shaft 6-1 pivotally connected to the protruding end of the lifting drive member through a fisheye joint, the sliding shaft 6-1 is horizontally arranged, and multiple groups of sliding bearings 6-2 are installed on the sliding shaft 6-1.
