The outer wall of the slider 61 is fixedly installed with an arc plate 62. The differential housing is fixed by sleeve-fitting the outer wall of the three groups of arc plates 62. The disc 5 is provided with an arc groove 6 4, a slide bar 65 runs through the arc groove 64, and the outer wall of the inner slide bar 65 is squeezed by rotating the arc groove 64 provided on the disc 5, so that each slide bar 65 drives the slider 61 at the end to move toward the edge direction of the fixed disc 4, so that the slider 61 can drive the three groups of arc plates 62 to expand and squeeze and clamp the inner wall of the differential housing, and the slide bar 65 is fixedly installed on the bottom wall of the slider 61, and a rotating rod 66 is fixedly passed through the inside of the disc 5, and the rotating rod 66 runs through the inside of the fixed disc 4, and the rotating rod 66 is rotatably connected to the inner wall of the fixed disc 4.
