They are often used in furniture products such as desks and cabinets. The structure of the drawer generally includes two side plates, a bottom plate, a rear plate and a cover plate. The bottom ends of the two side plates are respectively coupled with the two sides of the bottom plate, and the bottom end of the rear plate is coupled with the rear side of the bottom plate. The two sides of the rear plate are respectively coupled with the rear ends of the two side plates, the bottom end of the cover plate is coupled with the front end of the bottom plate, and the two sides of the cover plate are respectively coupled with the front ends of the two side plates, through the side plates and the bottom plate After the rear plate and the bottom plate, the rear plate and the side plate, the cover plate and the bottom plate, the cover plate and the side plate are connected, the bottom plate, the side plate, the rear plate and the cover plate are surrounded by a cavity for holding the article. . Most of the drawers of the prior art use wood boards such as wood boards, fiberboards or particleboards. On the one hand, these wood-based boards will have restrictions on wood felling and the increasing price of wood as our forest resources decrease. On the other hand, the connection between the bottom plate, the side plate, the rear plate and the cover plate made of wood is usually spliced or nailed, making the drawer difficult to assemble and automating the drawer. Production creates obstacles. The drawer of the prior art is also assembled by using the bottom plate, the side plate, the rear plate and the cover plate of the plastic plate. However, the drawer made of the plastic plate is heavy in weight and brings people's use. Inconvenient; on the other hand, when the bottom plate, side plate, rear plate and cover plate of the plastic plate are connected to each other, it is usually necessary to make a metal frame first, and then lock the bottom plate, the side plate, the rear plate and the cover plate correspondingly. On the metal frame, the drawer is formed, which causes the complicated assembly process of the drawer, thus affecting the automatic production of the drawer.
