A plurality of anti-slip parts 11 are provided on the side of the pressure plates 10 that contacts the rear axle housing body 2, and the anti-slip parts 11 are evenly distributed. The anti-slip parts 11 are preferably rubber blocks. A limiting component for fixing the rotation angle of the force arm 9 is provided on one side of the slider 6. The limiting component can limit the rotation of the force arm 9, so that the anti-slip part 11 on the pressure plate 10 is always in contact with the rear axle housing body 2, and cooperates with the slider 6 to clamp and fix the rear axle housing body 2, to prevent the rear axle housing body 2 from rotating and changing the installation angle, thereby improving the installation stability of the device.

[0024] The limiting assembly includes a fixing plate 15, which is fixed to one side of the slider 6 by bolts. A threaded hole penetrating the fixing plate 15 is provided on the top of the fixing plate 15, and a threaded rod 16 is threadedly connected in the threaded hole. One end of the threaded rod 16 is rotatably connected to a push block 13. The corner of the push block 13 in contact with the force arm 9 is arc-shaped, and a placement groove is provided in the arc-shaped portion. A rotating roller 20 is rotatably connected in the placement groove. The rotating roller 20 can reduce the friction force of the push block 13 squeezing the force arm 9, making the rotation of the force arm 9 easier. The other end of the lever arm 9 is an inclined surface 19. The top of the fixed plate 15 is fixed with a telescopic rod 14 by bolts, and the other end of the telescopic rod 14 is fixed to the push block 13.

[0029] S1: Adjust the positions of the two slides 3 according to the rear axle housing body 2, and adjust the position of the slider 6 through the power component, and then place the rear axle housing body 2 above the slider 6.

[0030] S2: Adjust the assembly angle of the rear axle housing body 2 and rotate the threaded rod 16 to move the push block 13. The push block 13 will squeeze the inclined surface 19 of the force arm 9 to rotate the force arm 9, so that the pressure plate 10 contacts the rear axle housing body 2, thereby clamping and fixing the rear axle housing body 2.
