Among them, the second knob 81 is placed in the rear end through hole of the support hand plate 5, the middle hole of the second slider limit plate 84 is fixedly connected to the second connecting shaft 86 when assembled, and the second clamping groove ring 85 is fixedly connected to the rear end through hole of the support hand plate 5.

[0031] The specific implementation method is as follows: when the protrusion on the second slider 83 is located at one end of the arc-shaped strip hole on the second rotation limit plate 82 close to the center of the circle, the second clamping groove ring 85 and the support hand plate 5 fixedly connected thereto can rotate around the second connecting shaft 86, and are now in an unlocked state, and the angle of the support hand plate 5 can be adjusted. After the angle adjustment is completed, the second knob 81 is rotated ninety degrees, and the second rotation limit plate 82 rotates accordingly, and the protrusion on the slider 83 slides along the arc-shaped strip hole on the second rotation limit plate 82 and enters the end away from the center of the circle. Under the action of the second rotation limit plate 82 and the second slider limit plate 84, the second slider 83 moves radially in the direction away from the center of the circle, and its end enters the clamping groove of the second clamping groove ring 85. The second clamping groove ring 85 and the support hand plate 5 cannot rotate, and the angle of the support hand plate 5 is locked. Example
