Abstract
The utility model belongs to the technical field of pneumatic wrench, and particularly relates to a pneumatic wrench which comprises the following components: a transmission shaft, a pneumatic rotor which is equipped in a same axis of the transmission shaft, a cylinder which is sleeved outside the pneumatic rotor, a wrench body, a front cover and a back cover which is provided at the front part and the back part of the cylinder, an air inlet channel and a pneumatic switch which are communicated with the cylinder, a hammering chamber housing which is provided outside the transmission shaft and engages with the pneumatic rotor for transmission, and a front jacket. A hammering block is fixed in the hammering chamber housing through fixing pins. The inside of the tail end of the front jacket is provided with an annular groove. A front cover of the cylinder is blocked in the annular groove. A sealing ring is provided between the front jacket and the body. The front jacket and the wrench body lock the cylinder tightly through connection screws. The tail part of each installation hole of the hammering chamber housing is provided with a neck reduction part for spacing the fixing pin which is provided in the installation hole. Hammering blocks are positioned between the fixing pins and the transmission shaft through fixing pins. According to the utility model, the front jacket and the body are connected with the locking cylinder. The structure is simple and the sealing performance is excellent.
