[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention. Example

[0017] See also Figure 1 to Figure 2The utility model provides a warning device for a grinding and polishing machine, including a warning component coaxially sleeved on a protective cover, the warning component including a lamp holder 2, a base plate 4 and a transparent lamp cover 3, all of which are annular, from top to bottom; the lamp holder 2 and the lamp cover 3 are bolted together through a plurality of connecting columns 6, and the lamp holder 2 is bolted to the lower end of the head; the connecting column 6 is arranged on the base plate 4; a plurality of warning lights 5 are embedded in a circular array at the lower end of the base plate 4, and the plurality of warning lights 5 are divided into three groups flashing different colors.

[0018] The substrate 4 here can be a PCB circuit board, and the corresponding connecting column 6 passes through the substrate 4 and is fixed with transparent glue. A threaded through hole is provided in the connecting column 6, and the connecting column 6 is bolted to the lamp holder 2 and the lamp cover 3.

[0019] Preferably, the flashing colors of the three groups of warning lights 5 are red, blue and white respectively.
