ABSTRACT:
A driver bit holding sleeve 6 is disposed in a shooting portion 4 so as to enable it to be rotated together with a driver bit 5 struck by a striking piston 2 while permitting the driver bit 5 to be slidably displaced in the shooting portion 4, and a piston-cylinder mechanism 10 for rotationally driving the holding sleeve 6 is arranged in the vicinity of the shooting portion 4. The piston-cylinder mechanism 10 is operatively associated with the holding sleeve 6 via a converting mechanism 17 for converting reciprocable linear movement of the piston-cylinder mechanism 10 into rotary movement of the holding sleeve 6. Since a striking sleeve 7 is threadably squeezed in a material to be handled after it is struck by a driver bit 5, any type of striking screw 7 having a circular head portion can easily and reliably be struck in the material.
