[0027] Reference Figure 1 , on both the front and rear sides of the top of the guide box 3, there are multiple first alignment blocks 13 fixedly connected, on both sides of the top of the clamping device 2, there are second alignment blocks 14 fixedly connected, and the first alignment blocks 13 are used in cooperation with the second alignment blocks 14.

[0028] As a technical optimization scheme of the present utility model, by setting the first alignment blocks 13 and the second alignment blocks 14, it is convenient for the user to adjust the position of the clamping device 2, avoiding the phenomenon that the clamping block 11 cannot be inserted into the interior of the clamping device 2 when moving the clamping device 2.

[0037] The working principle and usage process of the present utility model: When in use, first rotate the rotating block 12. The rotating block 12 drives the rotating rod 5 to rotate. The rotating rod 5 drives the elliptical push block 6 to rotate. When the elliptical push block 6 rotates, it pushes the push plate 7 to move outwards. The push plate 7 drives the connecting block 8 and the moving plate 9 to move outwards. The moving plate 9 drives the clamping block 11 to move outwards, so that the clamping block 11 moves away from the clamp 2. After moving away, push the clamp 2 inwards. After adjusting to an approximate distance, align the first alignment block 13 and the second alignment block 14. After alignment, release the rotating block 12. The elastic force of the return spring 10 drives the moving plate 9 to move inwards. The moving plate 9 drives the clamping block 11 to move inwards, so that the clamping block 11 is inserted into the clamp 2 again to limit the clamp 2.

[0038] In summary, for the positioning tooling of the steel pipe cutting device, by rotating the rotating block 12, the rotating block 12 drives the rotating rod 5 to rotate, the rotating rod 5 drives the elliptical push block 6 to rotate, and when the elliptical push block 6 rotates, it pushes the push plate 7 to move outward. The push plate 7 drives the connecting block 8 and the moving plate 9 to move outward, and the moving plate 9 drives the clamping block 11 to move outward, so that the clamping block 11 moves away from the clamp 2. After moving away, the clamp 2 is pushed inward. After adjusting to an approximate distance, the first alignment block 13 and the second alignment block 14 are aligned. After alignment, the rotating block 12 is released, and the elastic force of the return spring 10 drives the moving plate 9 to move inward. The moving plate 9 drives the clamping block 11 to move inward, so that the clamping block 11 is inserted into the clamp 2 again to limit the clamp 2. Thus, it has the advantage of adjusting the positioning length, and solves the problem that most of the existing positioning toolings are fixed, which makes the positioning tooling unable to fix short steel pipes, increases the operation difficulty of users, and reduces the practicability of the positioning tooling.
