Abstract: The present invention provides a pneumatic tool enabling sectional adjustment of torsional force, including a main body and a cylinder mounted into the accommodation space of main body. The cylinder is fitted with air vents and also a rotor. A plurality of exhaust holes is arranged at one side of the cylinder tube of the cylinder. An exhaust duct switching member is arranged between the exhaust holes of the cylinder tube and air exhaust duct of the main body and used to switch the airflow for air exhaust by different exhaust holes. The pneumatic tool enables sectional adjustment of its torsional force, thus promoting the torsional force efficiently with better applicability.

Abstract: The present invention provides a reciprocating pneumatic tool mechanism, including a casing, pneumatically-operated control module, control switch, actuating module and vibration-absorbing member. The plates of the actuating module are combined into a single body by the perforating locator. The periphery of the plates can be slidably abutted with the inner wall of the tank. The air inlet of actuating module is adapted air-tightly with air supply end of pneumatically-operated control module. At a front end of the actuating module, a protruding tube is screwed into a punch hole in front of the casing. The vibration-absorbing member includes a built-in buffer between actuating module and pneumatically-operated control module, and a front-mounted buffer between the front ends of actuating module and casing. With the invention, the vibration-absorbing members of reciprocating pneumatic tool is saved, improving the assembly efficiency, reducing assembly cost and volume with better economic efficiency.
