Abstract

The invention discloses a pin puller which comprises a cylinder-shaped rod body, wherein a threaded shaft is arranged at the front end of the cylinder-shaped rod body; the diameter of the threaded shaft is smaller than the diameter of the cylinder-shaped rod body; and a lug boss is formed at the back end of the cylinder-shaped rod body. As the technical scheme is adopted by the pin puller, a pin is pulled out after the threaded shaft is utilized to be connected with one end part of pin, so that the pin can be separated from a machine component more easily. The pin puller has the advantages of simple structure and low cost, and is convenient to use.

Description
