Pneumatic lever clamping structure for tapping machine

The invention provides a pneumatic lever clamping structure for a tapping machine, and relates to the technical field of clamping structures, the pneumatic lever clamping structure comprises two clamping plates, the two clamping plates are symmetrically installed on the two sides of the top end of a main body, a trigger plate is of an L-shaped plate-shaped structure, a rectangular groove is formed in the upper portion of the inner end of the trigger plate, an inclined groove is formed in the trigger plate, and the inclined groove is communicated with the rectangular groove. The two ends of each inclined groove are each of an arc-shaped structure. When a clamping plate moves to clamp a workpiece, a trigger plate is in contact with the workpiece, so that the trigger plate can be stressed to move, an inclined groove of the trigger plate can control a round rod of an auxiliary part to move, the auxiliary part can pull a moving rod and a pressing head to move downwards, the pressing head can be located above the w
