Abstract
The utility model belongs to the technical field of pneumatic wrenches, and provides a pneumatic ratchet wrench. The pneumatic ratchet wrench solves the problems that a hexagon spanner and other tools are needed for adjusting the torque of a common pneumatic wrench, and a quite long time is wasted when an assembling project of fastening pieces in multiple types is finished, so that the requirements that the common pneumatic wrench is fast, simple and convenient to use in an actual using process cannot be met. The pneumatic ratchet wrench comprises a machine body, wherein a hitting set and a high-pressure air flow inlet connector are arranged at two ends of the machine body respectively, a trigger and a speed regulating switch are arranged on side portions of the machine body in an opposite mode, and a rotary knob which can be rotated manually for speed regulating is arranged on the outer side of the speed regulating switch. The pneumatic ratchet wrench has the advantages that the rotary knob is arranged in a protruding mode relative to the machine body, and therefore the operation of tightening of the rotary knob and the operation of releasing of the rotary knob are simple, a large number of working hours are saved, and the regulating effect is visible.
