A through hole is provided at one end of the main body 201, and bushings 206 are provided in the middle and at the other end of the main body 201. Second through holes are provided on the first connecting plate 204 and the second connecting plate 205, and a through hole corresponding to the bushing 206 is provided on the first connecting plate 204. The difference between the left single arm 200 and the right single arm 300 is that the main body 201 of the right single arm 300 has a third connecting plate 301 at the end near the second end plate 203, and the third connecting plate 301 has a through hole that matches the bushing 206; the main body 201 of the left single arm 200 has two fourth connecting plates 207 at the end near the second end plate 203, and both fourth connecting plates 207 have through holes corresponding to the bushing 206, as well as a third through hole. Both single arms need to be assembled. Each single arm is composed of multiple plates and bushings. It is difficult to position the various parts, and the assembly requires high precision, making the assembly process very difficult.
