Claims

[Scope of utility model registration request]

In a pin extraction tool, a male thread formed at one end of a shaft is screwed into a female thread of a predetermined pin, and the pin is extracted by applying an axial impact force to the shaft. A cylindrical case formed with a guide groove along the axis and a cam part, and a cylindrical case that is inserted so as to pass through the case in the axial direction, and a male threaded part at the tip. a shaft having a pressure receiving portion formed in each portion corresponding to the inner center portion; a hammer inserted into the shaft and reciprocating within the case with one rotation limit set at a position corresponding to the pressure receiving portion; a spring that biases the hammer toward the pressure receiving part; a crank arm rotatably supported on a part of the case; and one end rotatably supported on the crank arm; A slider arm, the other end having a claw portion that engages with the hammer through the guide groove, and a slide surface that can slide into contact with the cam portion.
