Connector connecting structure of composite material plate spring

The invention discloses a connector connecting structure of a composite material plate spring, which comprises an upper connecting rod with a central through hole, a lower connecting rod with a central through hole and a metal connector, an actuation pin including a tapered transition surface; the actuating pin is arranged in the central through hole; the supporting blocks are placed in the openings, distributed in the circumferential direction, of the upper connecting rod, and the conical transition surfaces abut against the inner surfaces of the supporting blocks; the expansion pipe is sleeved on the upper connecting rod, the inner surface of the expansion pipe is propped against the outer surface of the supporting block, and the outer surface of the expansion pipe is in contact with the composite material plate spring; wherein the actuating pin can move up and down in the central through hole, and is selectively fixed at a certain position; the structure can compensate the contact gap between the connectin
