The mounting plate 1 and the connecting plate only need to be subjected to a cutting process during production, compared with the multiple machining processes required by the production process of the components of the frame 100 of the prior art, the machining process is simpler and easier to produce. In an optional embodiment, the materials of the first supporting assembly 2, the second supporting assembly 3 and the mounting plate 1 are consistent, and can be ecological board, shaving board, plywood, fine woodworking board, fiber board, etc. Using the above materials can avoid the metal material melting and die casting process, further reducing the energy consumption and resource consumption in the production process of the components, and reducing the production difficulty.

[0031] The mounting plate 1 includes a first connecting portion 11 arranged in a first direction and a second connecting portion 12 arranged in a second direction, in Figure 1 the embodiment shown, the first direction is the front-back direction, and the second direction is the up-down direction.
