Torsional spring 601 and spring all can be when supporter fold condition accumulate elastic potential energy, the elastic potential energy that torsional spring 601 released can make bracing piece 200 rotate until by spacing muscle 101 backstop and keep the maximum angle between bracing piece 200 and the base 100, the elastic potential energy that the spring was accumulated can promote bracing piece 200 to rotate to the maximum angle but can't maintain unchangeable of position, compare torsional spring 601, the price of spring is lower and the installation is more convenient, consider the practicality, torsional spring 601 is preferred scheme, combine the back with the scheme of fifth embodiment, can remove locking structure's locking through the mode of pressing, torsional spring 601 pops out bracing piece 200 to maximum turned angle, switch the supporter from fold condition to the motion that expandes the state and just can accomplish of only needing one to press, it is very convenient to use.

When the locking structure is unlocked to lock the support rod 200, the elastic piece pushes the support rod 200 to rotate, the support rod 200 can normally rotate because the folded state of the shelf does not support heavy objects, the friction force between the rubber ring and the support rod 200 and between the rubber ring and the base 100 is small, when the heavy objects are borne, the friction force between the rubber ring and the support rod 200 and between the rubber ring and the base 100 is large, the rotation angle of the support rod 200 cannot be changed, and if the supported objects are small, the support rod 200 can be manually rotated to adjust the rotation angle.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification which does not depart from the functional and structural principles of the present invention is intended to be included within the scope of the claims.
