[0008] The beneficial effects of the utility model are:

[0009] The present design controls the movable guide seat to rotate around the fixed guide seat through a control device, thereby controlling the front end of the movable guide seat to swing left and right. When the grinding liquid needs to be refluxed for recycling, the front end of the movable guide seat is controlled to swing left so that the liquid outlet is located above the reflux chamber, and the grinding liquid refluxed from the reflux pipe is discharged from the liquid outlet to the reflux chamber after passing through the first flow channel and the second flow channel, and then the grinding liquid is sent back to the grinding liquid tank through the reflux chamber. If the grinding liquid needs to be discharged, the front end of the movable guide seat is controlled to swing right through the control device, and the grinding liquid falls into the liquid discharge chamber and is discharged outward. The present design can timely control the reflux or discharge of the grinding liquid, thereby eliminating the need to stop the equipment and also enabling the replacement of the grinding liquid.
