Mirror gun connecting mechanism with high repeated clamping precision

The utility model relates to a mirror gun connecting mechanism with high repeated clamping precision, which comprises a shell, a screw rod, a connecting rod, a connecting rod and a connecting rod, and is characterized in that a screw rod hole is formed in the middle of the shell; the tightening face is machined on one face of the shell, and the horizontal height of the tightening face is smaller than that of the screw hole 1. Compared with the prior art, the utility model has the advantages that a locking part (a locking screw and a locking nut) is arranged on the movable dovetail, and the position of a locking point is aligned to the central positions of two positioning points of the fixed dovetail, so that the dead center of the fixed dovetail is subjected to a pulling force vertical to the dovetail surface during locking, and the fixed dovetail is locked; the position and the direction of pulling force relative to the dovetail positioning face are not changed all the time, the length of the movable dovetai
