Problems solved by technology
The current adjustment structure will not be able to completely seal the airflow due to the plastic deformation of the sealing ring after a period of use, resulting in air leakage from the wind wrench
Moreover, the adjustment and control of the wind wrench needs to be completed by operating two control components. This structure reduces the convenience of actually using the stroke wrench.

The invention relates to a pneumatic air wrench air inlet regulating structure which comprises a handle body, a regulating module and an air inlet module. The regulating module and the air inlet module are arranged in the handle body. The regulating module comprises an air inlet valve seat assembly, a flow regulator and a direction rod. The air inlet valve seat assembly comprises an air inlet valve seat and a valve seat copper lining. The valve seat copper lining is pressed into the air inlet valve seat. An air inlet is formed in the air inlet valve seat. Multiple vent holes are formed in the valve seat copper lining. The air inlet module comprises a locking screw, a framework oil seal, an oblique valve, an oblique valve spring and an air inlet connector. The framework oil seal and the oblique valve jointly seal an air inlet channel. The control of forward and reverse turning, turning speed and torque force of a pneumatic air wrench is achieved through matching between the flow regulator and the valve seat copper lining, regulating operation steps are simplified, and usage convenience of the pneumatic air wrench is improved.
Description
technical field [0001] The invention belongs to the field of pneumatic tools, and specifically refers to an air intake adjustment structure of a pneumatic wind wrench. Background technique [0002] Pneumatic wind wrench is a hand-held demolition tool powered by compressed air, which is widely used in the fields of machinery, engineering or construction. The cylinder inside the wrench is driven by compressed air, and the torque at the end of the wrench is increased through the rotation of the cylinder and the reinforcing parts, so as to realize the installation or removal of bolts and the like. [0003] During the working process of the pneumatic wind wrench, different torques are required in different workplaces. At this time, the air intake volume needs to be adjusted. The currently used adjustment structure will not completely seal the airflow due to the plastic deformation of the sealing ring after a period of use, resulting in air leakage from the wind wrench. Moreover...
