The worktable inner frame can rise up and rotate in the horizontal direction arbitrarily. As the inner frame drops under the external frame, at this time the outer frame can work as worktable solely.

The surface of worktable is made from super macromolecules plastic, which reduce the damage to the lowest extent in the course of assembling PVC window and door.
