[0025] As a technical optimization solution of the present invention, the traction belt 21 can be guided by providing the support block 23 and the guide roller 24 , thereby reducing the wear of the traction belt 21 .
[0026] refer to Figure 1 、 Figure 2 and Figure 5 The inside of the regulator 8 is fixedly connected to a bearing, and the outer ring of the bearing is fixedly connected to the regulator 8, and the inner ring of the bearing is fixedly connected to the threaded rod 19, and lubricating oil is provided inside the bearing, and a sealing shaft cover is provided inside the bearing, and the sealing shaft cover is made of plastic material.

[0033] As a technical optimization solution of the present invention, the pull rope 7 woven from a plurality of sub-steel wire ropes has the advantages of being stretch-resistant and wear-resistant.
[0034] The working principle and use process of the present invention are as follows: when in use, the anchor rod passes through the anchor rod insertion hole 3, and then the first lock buckle 6 is connected to the hanging hole 5. Then the operator adjusts the distance between the second lock buckle 22 and the first lock buckle 6 as needed. The operator can pull the second lock buckle 22, and then pull the traction belt 21, and the second reel 10 wrapped with the traction belt 21 rotates. When the operator pulls out the traction belt 21 of a suitable length, the operator can rotate the handle 20 to drive the threaded rod 19 to rotate, and then drive the extrusion frame 18 to move to the left. During the movement of the extrusion frame 18 to the left, the bevel on the surface of the extrusion frame 18 will push the upper and lower movable frames 13 away from each other until the movable frame 13 The second teeth 14 on the surface mesh with the first teeth 12 on the surface of the first winding wheel 9 and the second winding wheel 10, thereby locking the first winding wheel 9 and the second winding wheel 10 to prevent the first winding wheel 9 and the second winding wheel 10 from rotating, thereby performing the first-level locking of the position of the traction belt 21. When the extrusion frame 18 moves to the left, it cooperates with the positioning block 17 to directly squeeze and fix the traction belt 21, thereby performing the second-level locking of the position of the traction belt 21.

Both hanging holes 5 can be connected to the first lock buckle 6;
[0035] The surface of the second winding wheel 10 is fixedly connected to a torsion spring 11. When the operator needs to reel in the excess traction belt 21 onto the surface of the second winding wheel 10, the operator adjusts the extrusion frame 18 to move to the right, so that the extrusion frame 18 is separated from the traction belt 21. At the same time, under the action of the tension spring 16, the upper and lower movable frames 13 approach each other until the first teeth 12 and the second teeth 14 are disengaged. Then, under the action of the torsion spring 11, the second winding wheel 10 is driven to rotate in the opposite direction, and the traction belt 21 is wound around the surface of the second winding wheel 10. This device fixes the anchor rod fixing seat 1 by the pull rope 7, the first lock buckle 6, the traction belt 21 and the second lock buckle 22 to prevent the anchor rod from falling.
