When in use, the first hydraulic cylinder 11 is opened, and under the action of the first hydraulic cylinder 11, the limiting ring seat 32 moves upward, and under the action of the clamping anti-slider 38, the anchor rod is pulled out, which has the advantages of preventing falling off and good clamping effect.
[0025] In some embodiments, the positioning ring 12 is fixedly installed at the bottom of the first hydraulic cylinder 11, and the limiting ring seat 32 is fixedly installed at the top and bottom of the second hydraulic cylinder 2. More specifically, the first hydraulic cylinder 11 is supported by setting the positioning ring 12, and the position of the limiting ring seat 32 is adjusted by setting the first hydraulic cylinder 11.
[0026] In some embodiments, the first slide grooves 33 are opened inside the limiting ring seat 32 and are three in number, and the second slide grooves 35 are opened on both sides of the first slide groove 33 and are six in number. More specifically, the first slide groove 33 is set to limit the first slider 391 to prevent the first slider 391 from shaking during movement.
[0027] In some embodiments, the first slider 391 slides inside the first slide groove 33, and the clamping anti-sliding block 38 is fixedly installed on the inner side of the first slider 391. More specifically, the clamping anti-sliding block 38 is limited by setting the first slider 391 to prevent the clamping anti-sliding block 38 from shaking during movement.
[0028] In some embodiments, the threaded rod 34 is rotated inside the limiting ring seat 32 through threads and there are three of them. The turntable 31 is fixedly installed on the outside of the threaded rod 34. More specifically, the position of the limiting plate 392 is moved by setting the threaded rod 34, and the first slider 391 is indirectly fixed and limited by the limiting plate 392.
[0029] In some embodiments, the limiting plate 392 rotates on the inner side of the threaded rod 34 through a bearing, and the second slider 37 slides in the inner cavity of the second slide groove 35. More specifically, the second slider 37 is limited by setting the second slide groove 35 to prevent the second slider 37 from shaking during movement.
[0030] In some embodiments, the connecting block 39 is fixedly installed on the inner side of the second slider 37, and the inner side of the connecting block 39 is fixedly connected to the surface of the clamping anti-sliding block 38. More specifically, the connecting block 39 and the clamping anti-sliding block 38 are limited by setting the second slider 37 to prevent them from shaking during movement.

More specifically, by setting the spring 36 to reset the second slider 37, the clamping anti-slider 38 and the anchor rod are indirectly initially fixed.
[0032] Working principle:
[0033] Step 1: When in use, the anchor rod passes through the inner cavity of the positioning ring 12, the first hydraulic cylinder 11 and the limiting ring seat 32 in sequence, and the gap of the limiting ring seat 32 is adjusted according to the length of the anchor rod. The second hydraulic cylinder 2 is opened, and the limiting ring seat 32 is driven to move by the second hydraulic cylinder 2, and the spacing between them is adjusted. After the adjustment, when the anchor rod is fixed, the second slider 37 drives the connecting block 39 and the clamping anti-sliding block 38 to move inward under the action of the spring 36, so that they are preliminarily fixed under the action of the clamping anti-sliding block 38;
[0034] Step 2: Then rotate the turntable 31, and the turntable 31 drives the threaded rod 34 to rotate, so that the position of the limit plate 392 changes and contacts the first slider 391. When the threaded rod 34 continues to move, the limit plate 392 drives the first slider 391 and the clamping anti-slider 38 to move inward and further fix the anchor rod. When in use, open the first hydraulic cylinder 11, and under the action of the first hydraulic cylinder 11, the limit ring seat 32 moves upward, and under the action of the clamping anti-slider 38, the anchor rod is pulled out, which has the advantages of preventing falling off and good clamping effect.
