In particular, a spring used to support the support rod is generally connected to the support rod. One end of the spring is fixed on the support rod, and the other end is fixed on the base. When the support rod pivots, the spring can support the support rod, so that the Prevents the pole from being unable to be positioned due to the weight of the screen.

However, each time the strut pivots, the spring lengthens or shortens depending on the angle the strut pivots, and the greater the angle the strut rotates, the more the spring stretches.

It is worth noting that when the spring is repeatedly stretched, it is easy to cause the elastic fatigue of the spring, which in turn makes the spring unable to support the weight of the screen hung on the support rod. Especially, the longer the spring is stretched, the easier it is to cause the elastic fatigue of the spring. In view of this, it is indeed necessary to solve the defect that the spring is repeatedly stretched by a large amount every time the strut is rotated.

SUMMARY OF THE INVENTION
