A tool assembly for a stroke which reinforces engaging force between a striking portion and a handle portion and prevents wear of the handle portion. The tool assembly includes a striking portion having a through-hole, a handle portion the upper portion of which is inserted into the through-hole of the striking portion to act as a knob for movement of the striking portion, a regulating device which penetrates through the handle portion and regulates the engaging degree of the handle portion and the striking portion by moving longitudinally with respect to the handle portion, thereby deforming the upper portion of the handle portion towards a direction perpendicular to the striking direction of the striking portion, and a reinforcing member which is mounted in the handle portion and absorbs vibration generated by the regulating device and prevents friction between the regulating device and the inner surface of the handle portion, thereby preventing wear of the inner surface of the handle portion. According to the tool assembly, the engaging force between the handle portion and the striking portion can be easily regulated. The vibration generated during the work is absorbed by the reinforcing member, the vibration is not transferred to a hand of a user and noise is reduced. |
