A placement plate is fixed on the top of the support plate, and a clamping mechanism for clamping the resin grinding wheel is installed on the placement plate. The clamping mechanism includes a hydraulic cylinder fixed on the top of the placement plate, and the output end of the hydraulic cylinder is fixedly connected to the pressing cylinder at the bottom of the placement plate, and a U-shaped groove is provided at the bottom of the pressing cylinder. A limiting mechanism for fixing the resin grinding wheel is provided on the base. The limiting mechanism includes a fixed seat arranged on the base and a spring mounted on the fixed seat, and the upper part of the fixed seat is provided with a clamping hole for use with the insertion rod.

[0003] In the process of implementing the above embodiments, it is found that there are at least the following problems in the related art:

[0004] The hydraulic cylinder drives the pressing cylinder to move to squeeze the spring, so as to facilitate the insertion of the pin into the fixing seat. After the insertion is completed, the resin grinding wheel can be pressed and fixed under the elastic force of the spring. However, due to the lack of a corresponding fixing mechanism, the stability of the fixing seat after being placed on the base is poor. In the process of the pressing cylinder pressing the spring, the fixing seat is easily tilted, affecting the smooth pressing of the resin grinding wheel.
