Technical Examples

A pneumatic wrench includes a pneumatic motor, a striking portion, and a drive shaft. The striking portion includes a support seat, a first pin, a second pin, a first hammer, and a second hammer. Thus, the locking strip of the first hammer and the locking strip of the second hammer increase the thickness of the first hammer and the second hammer respectively to reinforce the structural strength of the first hammer and the second hammer, thereby preventing the first hammer and the second hammer from being broken due to vibration so as to increase the lifetime of the first hammer and the second hammer.
