As shown in Figures 4 and 7, after the support is placed on the slope, the convex arc surface 134 is supported by the concave arc surface 122 and slides relative to the concave arc surface 122 under its own gravity or other external forces, and the plane on the support plate and the slope surface will meet. If the included angle changes, the level of the plane on the support plate can be leveled by a spirit level,

As shown in Figure 2, in order to adjust the height of the screw rod 12 conveniently, the center of the support plate is provided with a through hole 132, and the center of the screw rod is provided with a convex column 123 protruding from the concave arc surface, and the function of the convex column is to limit The range of motion of the support plate and prevent the support from slipping. An insertion hole 1231 is defined at the center of the protrusion. As shown in FIG. 5 , a wrench 16 that drives the screw 12 to rotate can be inserted into the insertion hole 1231 . The wrench 16 is T-shaped, and has a driving head 161 on the head. The driving head 161 is inserted into the socket 1231 , and the screw 12 is rotated by rotating the wrench 16 , thereby realizing the height adjustment of the screw 12 . Of course, those skilled in the art can understand that the shapes of the driving head 161 and the insertion hole 1231 can be various, such as the strip shape adopted in this embodiment, or various polygonal structures.
