摘要： An electric hammer has a housing having a nozzle portion, a motor and a transmission mechanism arranged in the housing, a striking device, coupled to the motor and transmission mechanism, for moving in a reciprocating manner in the nozzle portion, and a clamping device mounted to the nozzle portion and at least partially extending out of the nozzle portion. The clamping device includes an outer sleeve, an inner sleeve arranged in the outer sleeve, and at least two clamping members arranged on the inner sleeve. The inner sleeve has a first position and a second position with respect to the outer sleeve and the distance between the two clamping members in the first position is less than the distance between the two clamping members in the second position to thereby allow a nail to be released halfway, i.e., when partially struck into a workpiece, in a simple manner.
