Abstract
Disclosed is steering drive device for a pressing-controlled valve core, the steering drive device including a fixed top frame, a lifting drive rod, a vertical guide column, a lifting receiving seat, a fork-shaped swinging member, and a steering linkage. The steering linkage has an end that swings laterally when being moved, and the laterally swinging end is provided with a through hole for the fork-shaped swinging member to drive the swing arm, and cause the horizontal post to axially slide. The vertical cross-section of the through hole is rectangular, and the drive horizontal column has a range of up and down movement space in it, so that, when the drive swing arm generates lateral displacement due to vertical swing, it will pull the steering linkage along a circular path laterally moving, and at the same time drives the valve to rotate the actuating seat and cause it rotate laterally.
