[0009] The first branch arm and the third branch arm are attached, the second branch arm and the fourth branch arm are attached, and first holes are formed in the corresponding positions of the first branch arm, the third branch arm, the second branch arm and the fourth branch arm.

[0010] A connecting sheet is welded on the outside of the sleeve.

[0011] Further, the first branch arm, the sleeve and the second branch arm edge are integrally bent and formed with an arc plate.

[0012] Further, the outer edges of the first branch arm, the second branch arm, the third branch arm and the fourth branch arm are provided with a round corner structure, and the round corner radius is greater than 3 times the plate thickness.

[0013] Further, the sleeve is vertically arrayed with second holes.

[0015] Further, the connecting sheet is provided in an L-shaped structure, and the end of the connecting sheet is provided with a wiring hole.

[0016] The beneficial effects of this utility model are:

[0017] By bending the first arm, sleeve, and second arm into a single unit, the number of welded joints is reduced, improving overall strength and fatigue resistance. Optimizing the geometry of the installation space through a specific angle ratio may improve load distribution and stress concentration. The design of the curved plate and the rounded corner radius being greater than 3 times the plate thickness significantly reduces stress concentration and improves fatigue life.
