[0002] Disc grinder is mainly used for medium-grade ores and cement clinker. It is one of the main equipment in laboratories or testing rooms in industries such as metallurgy, geology, building materials, and chemicals.

[0003] Chinese patent publication number CN218984414U discloses an automatic grinder that is easy to replace grinding discs, including two rollers symmetrically provided on one side of the lower end of the grinder body, a grinding device provided on the other side of the lower end of the grinder body, an armrest provided on one side of the grinder body, and a support and protection component provided on the outside of the grinder body. The staff presses the armrest to make one end of the grinder body tilt up, and then rotates the operating block to make the threaded rod move downward. The downward movement of the threaded rod makes the ball abut against the ground, and then continues to rotate the operating block. The threaded rod cooperates with the fixed block to make the protective cover deflect until one end of the protective cover abuts against the ground, thereby achieving the effect of stabilizing the grinder body, avoiding the need to manually press the armrest to maintain stability, and solving the problem of relatively wasteful operation.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] When the utility model is in use, if the movable grinding disc needs to be replaced, the fixing frame is opened and the connecting disc is pulled out, and the connecting hole is driven away from the first positioning rod when pulling it out, until the first positioning rod is completely moved out of the connecting hole, thereby removing the current movable grinding disc, and then the connecting hole of the new connecting disc is aligned with the first positioning rod and moved toward the positioning disc, until the first positioning hole on the surface of the first positioning rod is aligned with the second positioning hole on the surface of the second positioning rod. At this time, the first suction cup and the second suction cup are adsorbed together to maintain stability, and then the bolts are inserted into the first positioning hole and the second positioning hole and tightened, so that the movable grinding disc is fixed on the positioning disc, and the replacement is completed, thereby solving the problem of inconvenient replacement of the grinding disc.
