[0023] Furthermore, a bubble level 16 for conveniently adjusting the horizontality of the top plate 1 is fixedly installed on the top of the top plate 1 , and a handle 20 is fixedly installed on the top of the top plate 1 .

[0024] Furthermore, both ends of the support rod 6 are rotatably connected to the positioning plate 7 and the movable plate 2 via a rotating shaft.
