Pneumatic transmission device of feeder of plug-in machine

The pneumatic transmission device comprises a pneumatic motor and a transmission rod, one end of the transmission rod is provided with a piston, the inner surface of a connecting hole is connected with a rocking bar used for rocking a gear of an external plug-in machine feeder, and the rocking bar is used for being connected with the gear in the plug-in machine feeder; the pneumatic motor adopts a pneumatic mode to reduce the influence of the environment on the operation mode of the pneumatic motor, and when the pneumatic motor operates in severe environments such as water, dusty, humid, dirty and the like, the pneumatic motor adopts a gas compression mode, so that the internal pressure is larger than the external pressure when the pneumatic motor operates to obtain transmission force, and the pneumatic motor can normally operate by neglecting severe factors in the environment; the mode that the rocker drives the gear to rotate is adopted, so that the situation that the motor is damaged due to the reverse act
