Differential shell with good safety performance

The utility model relates to the technical field of differential shells, in particular to a differential shell with good safety performance, which comprises a differential shell body, a transmission shaft and a fixed sleeve table, the edge of the surface of the differential shell body is equidistantly provided with through side holes, and the lower end of the differential shell body is fixedly provided with a sleeve joint A. Due to high-speed rotation, a certain centrifugal force is generated, then the sealing plate overcomes the elastic force of the spring and slides out of the end opening of the end hole, the piston is driven to slide out of the end opening of the guide hole, and at the moment, the guide hole is communicated with the outside through the end hole. Dust and impurities adsorbed on the surface of the inner wall of the differential shell body due to the inertia effect finally enter the guide holes, and are discharged out of the differential shell body from the end holes under the centrifugal for
