[0012] By adopting the above technical scheme, the connecting torsion spring drives the limiting plate to change the longitudinal position, when the hanging ring exerts pressure on the limiting plate, the connecting torsion spring contracts, so that the hanging ring is fixed between the limiting plate and the limiting plate, and the limiting plate is not subjected to the pressure of the hanging ring, the connecting torsion spring resets, thereby driving the limiting plate to reset.

[0018] 1. The fixing component includes a hanging ring, a fixing block, a limiting plate, a movable groove, a limiting plate, and a connecting torsion spring. The connecting torsion spring causes the limiting plate to change its longitudinal position. When the hanging ring applies pressure to the limiting plate, the connecting torsion spring retracts, fixing the hanging ring between the limiting plate and the limiting plate. When the limiting plate is not under pressure from the hanging ring, the connecting torsion spring resets, thereby causing the limiting plate to reset, thus fixing the support foot.

[0019] 2. It also includes a slider and a slide groove. The slider and the slide groove complement each other and guide the limit plate during the movement, thereby effectively ensuring the stability of the limit plate when it moves longitudinally and preventing the limit plate from falling out of the movable groove.

[0020] 3. Additionally, it includes a stop block, which not only facilitates the limiting plate to be stopped when the hanging ring applies pressure to the limiting plate during downward movement, but also allows the operator to move the limiting plate downward through the stop block, thereby removing the hanging ring from between the limiting plate and the limiting plate, and unfolding the support leg for use.
