[0007] A support tube is provided on one side of the support plate, and one end of the support tube is bent and connected to the transverse axis tube assembly.

[0008] Furthermore, the longitudinal axis tube assembly is composed of a mounting bracket, a rubber sleeve tube, screws and square steel;

[0009] One end of the mounting bracket is welded with a rubber sleeve, and the other end passes through the support plate and is welded with a square steel. The mounting bracket is provided with two connection holes.

[0010] Furthermore, the transverse axis tube assembly is composed of a punched circular tube and two rubber sleeves. One end of the punched circular tube is welded to the two rubber sleeves, and the other end is welded to the connecting hole located at the top end of the mounting bracket.

[0011] Furthermore, one bent end of the support tube is welded to the supporting plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] This structure abandons the traditional rear support arm stamping parts welding, adopts bent pipe and square steel structure, reduces the development of stamping molds as much as possible, and shortens the development cycle; by cutting grooves on square steel and round pipe, overlapping and welding, when the round pipe and square steel are overlapped, holes are punched on the square steel, and the round pipe is inserted into the square steel to form a load-bearing welding structure, which meets the stress condition of large loads, ensures welding quality, and is easy to control welding deformation.
