Working principle of swing mechanism:

Under the action of hydraulic oil, the piston rods of the left and right swing valve cylinders are pushed to move. The piston rod drives the rocker arm, and the rocker arm drives the S valve to swing left and right, so as to realize the reversing of the S valve.
