[0002] In today's society, with the continuous development of urban construction and the increasing improvement of people's living standards, it is inevitable to use various boards such as gypsum board, fiber board, wood board and sound insulation board in the process of indoor and outdoor decoration. These boards often need to be processed, especially the edges of the boards need to be chamfered. Previously, workers usually use large cutting machines to process the edges of the boards, but this is not suitable for home decoration and other occasions. To this end, a gypsum board chamfering device suitable for home decoration is provided in the patent with the patent number "CN222245455U" and the patent name "a gypsum board chamfering device". The gypsum board chamfering device includes a chamfering device, a blade is installed at the top of the chamfering device, and a V-shaped chamfering groove is arranged at the bottom. When the gypsum board is placed in the V-shaped chamfering groove, the chamfering device is pushed to chamfer the edge of the gypsum board by the blade. Thus, although the gypsum board chamfering device provided by the patent solves the problem that large cutting machines are not suitable for home decoration and other occasions.
