In the embodiment of the present utility model, the linkage mechanism 2 includes several connecting rods, and any two adjacent connecting rods are connected with guide positioning holes 201 and guide positioning pins 202, and any two adjacent connecting rods The connecting rods can rotate with each other, and any two adjacent connecting rods can slide with each other. The guide positioning hole 201 and the guide positioning pin shaft 202 can avoid the dead point position of the mechanism during the working process. Avoid causing the mechanism to be stuck.

In the embodiment of the present utility model, the guide positioning hole 201 is a through hole composed of a circular hole and a slot-shaped hole arranged along the length direction of the connecting rod. The slot-shaped hole is close to the end of the connecting rod. The width of the slot-shaped hole is smaller than the diameter of the circular hole, and there is an inclination angle between the length direction of the slot-shaped hole and the length direction of the connecting rod.

In the embodiment of the present utility model, the two ends of the guide and positioning pin shaft 202 have planes for matching with the slot-shaped holes, and the other two ends of the guide and positioning pin shaft 202 have planes for matching with the circular holes. Fitting curved faces.

In the embodiment of the utility model, several linkage mechanisms 2 are radially distributed with the center point of the ferrule 1 as the center.
