[Previous technology] In the conventional pneumatic tools, the L-shaped transmission structure is to be set with bearings and outer sleeves, screwed to the bevel gear directly to the output of the air motor, and the outer end shaft screwed. In the conventional pneumatic tools, which use transmission parts and can only work with a single bearing, relatively large parts are easily damaged. Most of them are set with L-type output. Bevel gears are set at one end of the transmission shaft. Bevel gears sleeved at the end of the shaft mesh in the screw holes of the shaft housing to transmit power to the L-type output directly to the outside. It is used for the dynamic support of the external drive shaft. When the work piece is eccentrically loaded, the transmission set of the pneumatic tool has no known mechanical tools, and it is directly transmitted to the external eccentric load by the L-shaped output method. Power is subject to [new content] The secondary purpose of the eccentric drive assembly is less than two parallel support shafts, which are used to balance the two ends of the support shaft. The purpose of this creation is to provide a bevel gear for pivoting. Bearings on the base of the L-type transmission assembly to the two ends of each shaft are provided with bearings, respectively, which effectively provide L-type power transmission.
