Claims

[Scope of utility model registration request]

A piston integrated with a driver for striking a stopper, etc.; a cylinder that houses the piston and is slidable; and a sleeve that is slidable in circumference of the cylinder and that functions as a valve to control the inflow of compressed fluid into the cylinder. a damper for enabling a lower end surface position of the piston to be moved in a striking direction in a driving machine having a structure in which the driver is pushed up to start striking and the striking is repeated a number of times to drive a stopper; A is disposed below the piston, one end supports and fixes the damper A, and the other end is disposed with a guide sleeve whose distance to the driver can be adjusted,
Distance A between the O-ring of the piston and the small hole of the cylinder
, and an output structure in which the distance B between the driver and the other end of the guide sleeve can be adjusted.
