[0001] The utility model relates to the technical field of grinders, in particular to a positioning mechanism of a grinder. Background Art

[0002] When a product needs to be processed by a grinder, the product needs to be placed on a carrier, and then the carrier is positioned on the grinding disc for processing. In the past, multiple sets of guide wheels were used to position the carrier, but multiple sets of carriers are usually installed on the grinding disc to achieve the processing of multiple sets of products.
