[0004] However, there are some problems in the use of the existing grinding head: 1. At present, for grinding larger size spheres such as spheres above four inches, there is no problem due to the large space distance of the grinding head, but when grinding spheres of three inches or less, the grinding head is small in size, and wide and large sand strips cannot be selected, so only small sand strips can be used to grind with four-hole grinding heads or only two sand strips can be used to grind. 2. Due to the small contact area of the small sand strips or two sand strips, the grinding efficiency is low, the sand strips are consumed greatly, and the sand strips need to be replaced frequently. In addition, the surface roughness of the ground sphere is poor. UTILITY MODEL CONTENTS
