Abstract

An electric hammer includes a striking device having a clamping mechanism. The clamping mechanism includes a clamping element, a sliding element, a first biasing device and a second biasing device. The sliding element is provided with a guide portion in which the clamping element is slidable between a first position where the clamping element is closed and a second position where the clamping element is opened. The biasing force generated by the first biasing device is smaller than that of the second biasing device when the clamping element is in the opened position.
