An auto hammer includes a housing having a grip, a head assembly arranged on one end of the housing, a motor mounted within the housing, a switch arranged on the housing for controlling the motor. The head assembly includes a striking device having a receiving cavity which comprises a locking mechanism. When the receiving cavity is retracted into the housing and locked by pressing the locking pin downwardly, with the striking rod being revealed to increase the visibility of the striking rod. During operation, the objects to be processed, such as tenons and bricks, may be impacted by the striking rod in a linear reciprocating manner, so that the function of the tool can be expanded, without being limited to knocking the fastening pieces into the objects to be processed.
