Claim:
An electric hammer, comprising: a striking device having a clamping mechanism and an impact assembly; the clamping mechanism comprising: clamping elements; and a sliding element provided with a guiding portion in which is slidably retaining the clamping elements, wherein the clamping elements are slidable between a first position with respect to the guiding portion where the clamping element are closed and a second position with respect to the guiding portion where the clamping element are opened; the impact assembly comprising: a striking element having a first end defining an impact portion and a second end defining a striking portion; and an impact wheel; a connecting piece connecting the clamping mechanism to the impact assembly; a first biasing element to bias the sliding element away from the impact assembly to enable the clamping elements to be located in the closed position; and a second biasing element to bias the connecting piece away from the impact assembly, wherein the impact wheel contacts with the impact portion of the striking element, and the first biasing element and the second biasing element are positioned between the striking portion of the striking element and the impact wheel, and wherein a biasing force generated by the first biasing element is smaller than that of the second biasing element when the clamping element is in the opened position.
