Abstract: A universal connector contains: a lock seat and a U-shaped rotation element. The lock seat is mounted on a sucker, and a T-shaped rivet is configured to rotatably connect the lock seat and the U-shaped rotation element. The U-shaped rotation element has a U-shaped opening opposite to the lock seat, two orifices defined on two extensions of two sides of the U-shaped rotation element, and a first cap screw bolt accommodated in the two orifices and fixed perpendicular to the T-shaped rivet. In addition, the sucker includes a pump configured to pump airs out of the sucker.
