Preferably, the arc-shaped surface of the lower pin is a concave arc, and correspondingly, the arc-shaped surface of the cover plate is a convex arc.

Preferably, the cover plate is rotatably connected to one side of the cover plate support member by a connecting cross arm, the elastic member is connected between the connecting cross arm and the cover plate support member, and the other side of the cover plate support member is mounted on the second top roller shaft, so that the cover plate is floatable with respect to the second top roller shaft.

Preferably, the cover is rotatably connected to the link crossbar such that the cover can swing at an angle relative to the link crossbar.

Preferably, the lower pin is approximately Y-shaped, the upper transverse side of the Y-shaped is a concave smooth transition curved surface, the lower part of the Y-shaped is a straight side, and the lower pin is positioned by inserting the lower side into the middle roller supporting seat. Thus, the connection is convenient and simple.

Preferably, a gap of 0.5-4 mm is formed between the arc surface of the lower pin and the arc surface of the cover plate.

Compared with the prior art, the invention has the advantages that:

1. because the existing lower rubber ring is cancelled, the maintenance is simple, and the maintenance cost and time are saved; and the drawing power consumption is reduced.

2. The elastic cover plate component can be better matched with the lower pin to form a swinging elastic jaw.
