[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model, through the setting of a fixing mechanism and a limiting mechanism, activates the fixing mechanism when deburring the surface of a magnesium oxide rod, thereby fixing both ends of the magnesium oxide rod. At this time, the pad moves into the fixing sleeve under the pressure of the magnesium oxide rod. During the movement, the pad compresses the buffer pad, and the gas inside the buffer pad is transported to the piston cylinder through the through hole after being compressed. The gas pressure inside the piston cylinder increases. At this time, the piston pushes the push rod and the limiting clamp to one side of the magnesium oxide rod under the action of the gas pressure, thereby further fixing and limiting the magnesium oxide rod, improving the surface treatment effect of the magnesium oxide rod, and preventing the position of the magnesium oxide rod from changing due to the vibration generated during grinding, which would affect the surface treatment of the magnesium oxide rod.

[0015] 2. This utility model, through its set moving mechanism and grinding mechanism, allows for the following process: After the magnesium oxide rod is fixed, the moving motor is activated, which drives the displacement block to move, thereby moving the grinding mechanism on the surface of the magnesium oxide rod. During this process, the rotating motor is activated, which drives the magnesium oxide rod to rotate, thus completing the grinding treatment on the surface of the magnesium oxide rod. During this process, the hydraulic cylinder drives the connecting seat to move downward, and the scraper first acts on the upper part of the magnesium oxide rod. As the hydraulic cylinder moves downward, the support seat moves upward under pressure, while the swing plate deflects downward under the action of the support seat, so that the grinding rollers act on both sides of the outer circumference of the magnesium oxide rod. Thus, the surface of the magnesium oxide rod is treated by the two grinding rollers. At the same time, the scraper can remove the debris generated during grinding, thereby improving the grinding effect of the magnesium oxide rod. Attached Figure Description
