[0002] A mechanism in which the piston rod performs reciprocating linear motion powered by oil pressure or air pressure. It can perform reciprocating linear motion cyclically and is widely used in industrial manufacturing and production. The counterweight of a forklift is to balance the center of gravity of the forklift so that the center of gravity of the forklift as a whole does not deviate from the area where the four wheels of the forklift are located during the operation of the forklift. The counterweight of a forklift is generally a concrete structure, and concrete is usually poured into a mold to form the concrete in the mold. After the concrete is dried, it is made into a balance block.

[0003] In order to allow the concrete to be filled into the dead corners in the mold during concrete filling, a piston rod is usually used to swing the filling barrel to change the landing point of the concrete so that the concrete can fill the dead corners and ensure the strength of the corners of the counterweight. However, the existing piston rod is usually provided with one and acts directly on the filling barrel, which makes the movement stability of the filling barrel insufficient and prone to shaking perpendicular to the movement direction of the piston rod.
