[0028] When the height of the grinding head 1 needs to be adjusted, the clamping sleeve 54 is first pulled downward to make the clamping sleeve 54 slide downward, releasing the limit of the threaded sleeve 53, and then the threaded sleeve 53 is rotated. At this time, the screw 51 threadedly connected with the threaded sleeve 53 will move upward, thereby achieving the purpose of adjusting the height of the grinding head 1. When the grinding head 1 is adjusted to a suitable position, the clamping sleeve 54 is released. At this time, the clamping sleeve 54 will return to its original position under the elastic force of the spring 1 55, thereby limiting the threaded sleeve 53 and preventing the grinding head 1 from sliding downward.
