For production, processing and transportation, after it is sent to the destination, it is assembled with the plates by screws and other hardware accessories to form the entire cabinet structure. The current cabinet installation structure usually exposes some hardware accessories such as screws on the outside or inside of the cabinet, which not only affects the overall aesthetics, but also scratches the items during use, which affects the use effect. Some designs allow a plastic fastener to be fastened on the outside of hardware accessories (mainly screws). Although it can alleviate the above problems to a certain extent, it still does not fundamentally solve the problem, and the integrity is still not good.
