In the use, when the user moves the support member 1 from the unfolding position to the folding position, the user only needs to rotate the support member 1 to the position closer to the fixing member 3, and when the first flat surface 221 and the second flat surface 71 can be abutted against each other, the elastic force of the elastic limiting tube 22 can be utilized to enable the support member 1 to automatically move to the folding position, so that the use is facilitated.
