Claims

[Scope of utility model registration request]

First and second holes are located on one side and the other side of the large diameter portion
A body in which a bore with a small diameter part is formed is constructed by connecting first and second blocks, and a spring is tensioned between the first and second retainers disposed in the large diameter part, and the body is formed with a bore having a small diameter part. first and second pistons each having a protruding rod are fitted into the first and second small diameter portions to form first and second hydraulic pressure chambers outside the first and second pistons; and an inner rod of a second piston is coupled within the large diameter portion for relative radial displacement, and an outer rod of the first piston and an outer rod of the second piston are formed on both sides of the body, respectively. A hydraulic actuator that protrudes outward through a hole.
