More Information
Summary:The limiting device comprises a piston (1), the piston pin (4) and a connecting rod (7), the piston is installed in an inner hole of a sliding guide (2) and axially moves in a reciprocating mode, and the outer wall of the large head end of the piston is in axial sliding contact with the inner hole wall of the sliding guide; a piston inner hole (11) and a piston pin hole (12) which are axially perpendicular are formed in the rear portion of the large end of the piston, a connecting rod bush (3) is embedded in a connecting rod small end inner hole, the connecting rod small end is installed in the piston inner hole, and a piston pin penetrates through the piston pin hole to be inserted into the piston and penetrates through an inner hole of the connecting rod bush to enable the piston and the connecting rod to be connected in a fastened mode. Point contact convex parts (41) with semi-spherical structures are formed at the two ends of the piston pin, so that the point contact convex parts are in instantaneous poi
