徴とする打撃工具。[Claims for Utility Model Registration] The rotational force of the motor is transmitted to the intermediate shaft via the first gear, and the rotational force of the intermediate shaft is transmitted to the cylinder via the second gear. The intermediate shaft is always biased in the direction of the tip tool and has a function of retreating in a controlled manner against the spring when the tip tool is pressed against the workpiece. When it engages with a clutch that is slidably attached in the axial direction,
A reciprocating bearing is loosely fitted to actuate the piston installed in the cylinder and provide reciprocating motion to the tip tool, and the reciprocating bearing is linked to the reciprocating motion of the cylinder and reciprocates the driving force of the intermediate shaft when retracting. In a striking tool equipped with a clutch that transmits power to the bearing and disengages the reciprocating bearing from the intermediate shaft during forward movement, the clutch is slidably mounted in the axial direction of the intermediate shaft on a thrust receiver that moves together with the cylinder. A striking tool characterized by being provided with a locking part that engages with and moves together with the impact tool.
