The drive motor 4 is connected to the second movable seat 3-2 through a bracket, and the output end of the drive motor 4 is connected to the drive shaft on the second movable seat 3-2 side.

[0022] It is worth noting that the specific structure and working principle of the grinding device body 1 are existing technologies that are already publicly available on the market, and are not the main technical problems to be solved in this utility model. Therefore, this utility model will not elaborate on them. The first movable seat 3-1 and the second movable seat 3-2 are made to move towards each other or away from each other by the bidirectional screw drive assembly 2.

[0023] The clamping assembly 5 includes a fixed base, in which a detachable arc-shaped clamping assembly is slidably disposed, and on both sides of the fixed base at the arc-shaped clamping assembly, a first pressing assembly and a first screw assembly 54 are sequentially disposed.

[0024] Furthermore, the arc-shaped clamping assembly includes a clamping arc block 53, one end of which is equipped with a T-shaped slider 531, and a placement cavity 51 is provided in the fixing seat at the clamping arc block 53.

[0025] Meanwhile, a groove is provided in the fixed seat at the T-shaped slider 531, and an inlet / outlet groove 52 is provided in the fixed seat between the T-shaped slider 531 and the placement cavity 51 and on the side away from the middle of the fixed seat.

[0026] Meanwhile, the first pressing component includes a pressing arc block 56, a second screw assembly 55 is provided in the middle of one side of the pressing arc block 56, and guide rods 57 are symmetrically installed at both ends of one side of the pressing arc block 56.

[0027] Furthermore, both the first screw assembly 54 and the second screw assembly 55 are threadedly connected to the fixed seat. The fixed seat has a threaded through hole at the screw body. Both the first screw assembly 54 and the second screw assembly 55 include a screw body. Limiting rings and handles are respectively installed at both ends of the screw body. A movable part 541 is sleeved on the outside of the limiting ring of the first screw assembly 54.

[0028] Meanwhile, a second cavity is provided on one side of the pressure arc block at the limiting ring and screw body.

[0029] Furthermore, the movable component 541 includes an auxiliary ring. A locking protrusion is symmetrically installed on both sides of one end of the outer wall of the auxiliary ring, and an marking protrusion is symmetrically installed on both sides of the other end of the outer wall of the auxiliary ring.
