Spherical gasket for automobile differential mechanism

The spherical gasket comprises a base, two sliding grooves are formed in the upper surface of the base, a sliding block is clamped in each sliding groove, a sliding plate is placed above the base, the upper surface of each sliding block is fixedly connected with the bottom face of the sliding plate, and the lower surface of each sliding block is fixedly connected with the bottom face of the sliding plate. A rotating motor is fixedly connected to the upper surface of the sliding plate, a baffle is fixedly connected to the left side face of the sliding plate, a transmission through hole is formed in the left side face of the baffle, the sliding plate is arranged to be matched with the baffle and the rotating motor, the right chuck can be driven to get close to the left chuck, and therefore the metal gasket is clamped; and when the right chuck is matched with the left chuck to clamp the metal gasket, the telescopic rod and the compression spring can be forced to contract, and when the telescopic rod and the comp
