The two nut assemblies are penetrated with bolts 52, the two connecting rod assemblies are respectively positioned at two sides of the bolts 52, the two nut assemblies can be displaced in opposite directions or in opposite directions relative to the bolts 52, and the angle adjustment is realized by adjusting the length of the diagonal line of the diamond structure.

The nut assembly includes a connection rod 53 and nuts 54 located at both sides of the connection rod 53, and the head of the bolt 52 replaces one of the nuts. The connecting rod 53 is provided with a hole for the bolt 52 to pass through, and two ends of the connecting rod 53 are respectively and rotatably connected with connecting rods of the connecting rod assemblies positioned at two sides of the bolt 52. The connecting rods 53 at the two connecting ends of the two groups of connecting rod assemblies 51 are respectively penetrated on the bolts 52, and the connecting rods 53 can freely move relative to the bolts 52 and are not limited by threads on the bolts 52. Nuts 54 are respectively sleeved on the bolts 52 on two sides of the connecting rod 53, and the connecting rod 53 is positioned through the nuts 54. When the nut 54 is loosened, the two connecting rods sleeved on the bolt 52 are moved in opposite directions to shorten the diagonal or are moved away from each other to lengthen the diagonal according to the requirement, and then the angle adjustment is realized through the positioning of the nut. The connecting rods are connected through rotating shafts in a driving way.

In some embodiments, the bolt 52 may be replaced by a threaded rod and a nut. In practice, bolts are preferably used, so that the number of parts and the assembling process can be reduced, and the adjustment time can be shortened.
