Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described further.

The bottom surface of the frame of Fig. 1 in the link shown in Figure 4 is the various embodiments of bottom surface, two inclined-planes, arc surface, curvilinear plane, broken line face.

Be provided with lug in the joint of bottom surface, oblique angle and bi-side in the link shown in Figure 5, when equaling the stationary plane width for the oblique angle bottom width, in inside groove, establish groove, fastening for lug.

The bi-side of the frame in the link shown in Figure 6 are the embodiment of arc surface.

Adopt hinged schematic representation between the bottom surface and side of the frame in the link shown in Figure 7, between side and the bottom surface.
