A is last card among the figure, and B and C are combined into a body frame, and E, G, F, H are combined into basic support.F is a wild card, and H is extension spring, and D is the lower support frame.R represents radius of a circle, and Figure 11,15,18,23 represents that all material therefor is round, and Figure 20 represents the hollow metal pipe material.

Number of assembling steps: by shown in Figure 3.1, two of E is stretched in outer two circular holes of going up of C, be converted into the right angle downwards at the 26mm place.2, the two with D enters in following two holes of C.3, extension spring H one end is caught on F, the other end enters in the G pipe, pulls out termination that is stuck in G of extension spring, and G inserts two holes in the middle of the C, and two sleeves that insert B again are interior fixing.4, A is put into two holes of B.5, B and C merging are fixed with screw.6, fixing two of E and G joinings, the overall package dress finishes.
