Specifically, the base 11 is provided with a reference surface 111, and when the base 110 is placed on a horizontal plane, the reference surface 111 is parallel to the horizontal plane. One end of the rotating block 121 is rotatably installed on the base 11 so that an angle between the surface of the rotating block 121 and the reference surface 111 is adjustable. The reversing cylinder 122 is transversely and fixedly arranged on the bottom surface of the rotating block 121, and the reversing cylinder 122 is positioned at the end of the rotating block 121 far away from the rotating connection with the base 11. In this way, when the rotating block 121 rotates relative to the base 11, the reversing cylinder 122 can be made to approach or separate from the reference surface 111. It should be noted that when the rotating block 121 is rotated to make the outer side wall of the reversing cylinder 122 abut against the reference surface 111, the surface of the rotating block 121 is in a horizontal state, so that the rotating block 121 and the base 110 are in a parallel structure. Further, the lamination 123 is adapted to be placed on the reference surface 111, so that when the rotary block 121 rotates, the outer sidewall of the reversing cylinder 122 abuts against the top surface of the lamination 123 and does not abut against the reference surface 111 any more, and thus the thickness of the lamination 123 is set according to the actually required inclination angle of the rotary block 121, so that the inclination angle of the rotary block 121 can be rapidly set using the lamination 123. It should be noted that the utility model utilizes the pythagorean theorem of right triangle. According to the pythagorean theorem, the sum of the squares of the two right-angle sides is equal to the square of the hypotenuse, since the distance between the axis of the reversing cylinder 122 and the rotation center of the rotating block 121 is a constant value, which corresponds to the hypotenuse of the right-angled triangle, and the radius of the reversing cylinder 122 plus the thickness of the lamination 123 is one of the right-angle sides, which is also a constant value, the length of the other right-angle side can be calculated according to the pythagorean theorem. The angle between the bevel and the horizontal, i.e. the angle between the turning block 121 and the reference plane 111, can be determined. Therefore, the inclination of the rotating block 121 can be quickly set by machining a plurality of laminations 123 with different thicknesses in advance according to actual needs. Further, the sliding block 131 is slidably mounted on the rotating block 121, and the diamond blade 132 is fixedly mounted on the sliding block 131, so that when the grinding wheel 2 continuously rotates along the horizontal plane at a high speed, the diamond blade 132 can slide along the oblique direction by pushing the sliding block 131 to slide relative to the rotating block 121, thereby cutting the grinding wheel 2 into a slope structure.
