[0004] In the prior art, the limit column is usually welded to the panel, so the panel needs to be thickened to ensure that the strength meets the requirements (if it is too thin, there is a risk of welding through or breaking during use). However, when the panel is thicker, not only the processing difficulty (such as drilling, bending, etc.) increases, but also the use of the rear panel increases the use of raw materials, and the production cost is higher. Therefore, it is necessary to improve the structure. Utility Model Content
