The cavity is connected with a double-sided wedge block 23 in a sliding way, and the inclined surface of the double-sided wedge block 23 is connected with a single-sided wedge block 24 in a sliding way. A limiting block 25 for plugging limiting is fixedly connected to the side wall of the single-sided wedge block 24. The side wall of the double-sided wedge 23 is provided with a spring 26 for return adjustment. The two springs 26 are included, and one ends of the two springs 26 away from the double-sided wedge 23 are fixedly connected to the corresponding inner walls of the cavity. The end cover 13 is fastened and connected with the clamping assembly 2 through fastening bolts 27.

A plurality of fixing bars are arranged on the peripheral wall of the machine body shell 11 along the circumferential direction, and threaded holes are formed in the left ends of the fixing bars. The conveying end cap 12 is provided at the left side of the body housing 11 and is fixed by bolts. The right sides of the fixing strips are provided with slots, the inner walls of the end parts of the slots are provided with threaded grooves, and the inner walls of the side walls of the slots are provided with limit grooves. The front end of the fastening bolt 27 is in threaded connection with the thread groove, and the limiting block 25 is in plug-in limiting with the limiting groove.

The end cover 13 is provided with a plurality of through holes along the circumferential direction, and the clamping assembly 2 is inserted into the through holes and fixed by screws.
