The rotating shaft 421 has a plurality of rotatingly connected pawls 52 arranged in a circular array on its side surface. The pawls 52 and the rotating shaft 421 are installed with a return spring 53 therebetween.

[0044] In combination with a specific use scenario, by setting the ratchet disc 51 and the pawl 52 structure, the support arm 42 can be automatically reversed locked during downward adjustment. At the same time, the adjustable angle of the support arm 42 is increased, which facilitates the support arm 42 to adapt to different placement positions.

[0045] Further, the rotating shaft 421 is rotatably mounted with a reset ring 54, the reset ring 54 is provided with a plurality of arc-shaped grooves 541 on the side surface, the pawl 52 is fixedly mounted with a protrusion on the side surface, and the protrusion is slidably mounted in the arc-shaped groove 541.

[0046] It should be understood that, by setting the reset ring 54 part, it is convenient to control the retraction of multiple pawls 52 at the same time through the reset ring 54, and then it is convenient to retract the support arm 42.

[0047] In some feasible ways, the rotating shaft 421 is keyed connected with the support arm 42, the rotating shaft 421 penetrates the rotating disc 41, the rotating shaft 421 is fixedly mounted with a connecting piece on the outside, the pawl 52 is mounted on the connecting piece through the rotating shaft, and the two ends of the reset spring 53 are fixedly connected with the pawl 52 and the rotating shaft 421.
