[0023] The support mechanism 5 comprises a support rod 51, a fixing plate 52, a reinforcing rib 53, an inclined rod 54 and a shaft sleeve 55; the support rod 51 is fixedly mounted on the inner wall of the carrier plate 2, and the support rod 51 passes through the carrier plate 2, and two groups of support rods 51 are arranged, and the two groups of support rods 51 are arranged on the inner wall of the carrier plate 2 with the second shaft ring 4 as the central axis mirror image, and the two ends of the support rod 51 are fixedly mounted with an inclined rod 54, and the end of the inclined rod 54 away from the support rod 51 is fixedly mounted with a shaft sleeve 55, and the first shaft ring 3, the second shaft ring 4 and the shaft sleeve 55 are all in a concentric state, and the shaft sleeve 55 can be used to adjust the outer diameter of the differential. The shaft inside the shell 1 is doubly supported to improve the load-bearing effect of the differential housing 1. The fixing plate 52 is fixedly mounted on the outer wall of the bearing plate 2. Two groups of fixing plates 52 are provided. The two groups of fixing plates 52 are mirror-imaged on both sides of the bearing plate 2 with the bearing plate 2 as the central axis. One side of the reinforcing rib 53 is fixedly mounted on the outer wall of the support rod 51, and the other side of the reinforcing rib 53 is fixedly mounted on the outer wall of the fixing plate 52. By utilizing the inclined rod 54 to cooperate with the support rod 51, the reinforcing rib 53 and the fixing plate 52, the supporting force of the shaft sleeve 55 on the shaft can be evenly distributed on the bearing plate 2, thereby improving the load-bearing quality of the differential housing 1.

[0024] The above-mentioned positioning mechanism 6 includes a screw rod 61, a steel ball 62, and a knob 63; the screw rod 61 is threadedly connected to the inner wall of the inclined rod 54, and the screw rod 61 passes through the inclined rod 54.
