Abstract: An impact wrench includes a front housing and a motor. A transmission mechanism and an impact mechanism are disposed in the front housing. A transmission direction of a force outputted by the motor is changed via the transmission mechanism to drive a working member of the impact mechanism to rotate. A part of the working member is protruded and is exposed outside the front housing. The front housing includes a seat and a covering member which are detachably engaged. The detachable engagement between the seat and the covering member is convenient for a user to maintain an inside of the impact wrench.

Abstract: A dual-use nail magazine for alternatively accommodating a T-shaped nail strip or an inverted U-shaped nail strip includes a track bar defining a first channel for receiving the T-shaped nail strip when it is used alone, a second channel, and a third channel cooperated with the first channel for receiving the inverted U-shaped nail strip. A nail pushing mechanism has a rod member suspended in the second channel, a nail push plate movably sleeved onto the rod member and having a first nail-pushing portion inserted into the first channel, and a second nail-pushing portion inserted into the third channel, and a compression spring sleeved onto the rod member for supporting and moving the nail pusher along the first channel and the third channel so as to push the T-shaped nail strip in the first channel or the inverted U-shaped nail strip in the first and third channels.
