Specifically, when the second limiting hole is aligned with a different first limiting hole 111, the mounting plate 12 has a different rotation angle relative to the bracket 11, and at this time, after the first limiting pin 13 is inserted into the second limiting hole and one of the first limiting holes 111, the mounting plate 12 and the bracket 11 can be fixed, so that the mounting plate 12 is prevented from rotating continuously. When the rotation angle of the mounting plate 12 needs to be adjusted, other first limiting holes 111 can be controlled to be aligned with the second limiting holes.

The number of the first limiting holes 111 can be three, wherein one first limiting hole 111 realizes that the included angle between the mounting plate 12 and the horizontal plane is 60 degrees, one first limiting hole 111 realizes that the included angle between the mounting plate 12 and the horizontal plane is 70 degrees, and the other first limiting hole 111 realizes that the included angle between the mounting plate 12 and the horizontal plane is 80 degrees.
