PROBLEM TO BE SOLVED: To provide an inexpensive power hammer auxiliary tool, preventing both arms of a person from suffering from Raynaud's disease due to intense vibration in crushing hard concrete in the ground using the power hammer, reducing the fatigue of human body, efficiently performing concrete crushing work, and sensing little vibration. SOLUTION: In this power hammer auxiliary tool 1, a power hammer 4 fixed to a universal clamp 3 is located in the center of one elongated steel pipe 2, oblong recessed metal fittings 5 serving as a base isolation device provided at both ends thereof are held down by two workers at the same time to produce strong pressure in the power hammer, thereby easily achieving concrete crushing work. The intense vibration of the electric hammer is not sensed by the spring action of a base isolating device such as push spring, or rubber, which will produce the effect that vibration is little sensed on the body of the worker.
