[0030] During use, the two mounting brackets 1 are installed at the place where they are needed. The driving motor drives the threaded rod 6 to rotate. The rotation of the threaded rod 6 drives the moving block 7 to move on its outer wall. The movement of the moving block 7 drives the mounting plate to move.
