Abstract
A power-driven hammer drill,includes a rotary lever,for transmitting and disabling the transmission of the rotation of a motor,to a tool bit,and a slide lever,for transmitting and disabling the transmission of hammer blows to the tool bit,. The rotary lever,is formed with a chamfer,, whereas the slide lever,is formed with a straight portion,and a cut-out,which conforms to the circular edge of the rotary lever,. When the slide lever,is in the lowermost position with the rotary lever,fitted in the cut-out,, the rotary lever,is in the position to disconnect the rotation of the motor,to the tool bit,, and while in this position, the slide lever,cannot be slid to its uppermost position, in which hammer blows cannot be transmitted to the tool bit,. When the slide lever,is located in the uppermost position and the chamfer,of the rotary lever,is in the rearmost position, in which hammer blows cannot be transmitted to the tool bit,but rotation can be transmitted to the tool bit,, the straight portion,opposes the chamfer,across a narrow gap so that the rotary lever,cannot be rotated to the rotation disabling position.
