摘要： The present disclosure provides an impact wrench for detaching bolts or nuts together with socket. The impact wrench includes a pole, a driving member, an elastic member, and a connecting portion. The driving member is slidably and rotatably disposed to one end of the pole. The other end of the pole has a sleeving portion which may be a rectangular hole. The elastic member presses against the driving member and the pole to make the driving member continuously moving away from the sleeving portion. The connecting portion is configured on the pole or on the driving member. The connecting portion is adapted for a handle to be assembled thereon. Therefore, power tool may be attached to the sleeving portion to provide rotational impulse to detach bolts or nuts. User may hole the impact wrench by a handle which is assembled on the connecting portion, achieving convenience and safety operation condition.
