[0026] In the above structure, through the internal threads opened on the inner walls of the driving seat 13 and the movable seat 14, when the driving screw 12 is rotated, the driving seat 13 and the movable seat 14 can be driven respectively under the action of the driving screw 12, so that the driving seat 13 and the movable seat 14 can move inward at the same time, thereby changing the support angle between the connecting plate 10 and the outer wall of the pull plate 11.
