DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solution of the present utility model will be further described in detail below in conjunction with the preferred embodiments and their accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-3 , the present utility model provides a technical solution: a high-strength strain clamp, including a U-shaped ring 1. Inside the U-shaped ring 1, a connecting piece 2, a support block 3, and a fixing block 4 are respectively arranged from top to bottom. An accommodation groove 5 is formed in the inner wall of the fixing block 4. A first rolling body 6 is movably connected to the inner wall of the accommodation groove 5. A fixing nut 7 is fixedly connected to the inner wall of the support block 3. A movable screw 8 is movably connected to the inner wall of the fixing nut 7. A handle 9 is fixedly connected to the top of the movable screw 8. A push block 10 is fixedly connected to the bottom of the movable screw 8. The outer wall of the push block 10 is movably connected to a limiting block 11. A positioning block 12 is fixedly connected to the bottom of the limiting block 11. A storage groove 13 is formed in the inner wall of the positioning block 12. A second rolling body 14 is movably connected to the inside of the storage groove 13. By providing the U-shaped ring 1, the connecting piece 2, the support block 3, the fixing block 4, the accommodation groove 5, the first rolling body 6, the fixing nut 7, the movable screw 8, the handle 9, the push block 10, the limiting block 11, the positioning block 12, the storage groove 13, and the second rolling body 14, it is convenient to fix and position the wire through the positioning block 12, thereby improving the strength after connection, and it is beneficial to adjust the tension of the wire without completely disassembling later, improving the adjustment speed and the operation convenience, meeting the work requirements of people, and being worthy of popularization and use.

[0020] Furthermore, the front view of the fixing block 4 is arc-shaped, and the first rolling bodies 6 are evenly distributed inside the fixing block 4, which facilitates the effective sliding of the wire through the rolling of the first rolling bodies 6.

[0021] Furthermore, the opening diameter of the accommodation groove 5 is smaller than the diameter of the first rolling body 6, and the first rolling body 6 is rotationally connected to the fixing block 4 through the accommodation groove 5, preventing the first rolling body 6 from falling off and separating.

[0022] Furthermore, the movable screw 8 is rotationally connected to the limiting block 11 through the push block 10, and the limiting block 11 is in a "concave" shape structure, which facilitates the movable screw 8 to drive the push block 10 to slide through the push block 10.

[0023] Furthermore, the front view of the positioning block 12 is arc-shaped, and the second rolling bodies 14 are evenly distributed inside the positioning block 12, which facilitates the tight fixation and positioning of the wire through the positioning block 12.

[0024] Furthermore, the diameter of the opening of the storage groove 13 is smaller than the diameter of the second rolling body 14, and the second rolling body 14 is rotationally connected to the positioning block 12 through the storage groove 13, preventing the second rolling body 14 from falling off and separating.

[0025] During use, first insert the wire into the inside of the U-shaped ring 1 and position it between the fixed block 4 and the positioning block 12. Then, rotate by toggling the handle 9, so that the handle 9 drives the movable screw rod 8 to rotate. The movable screw rod 8 slides downward through the threaded connection with the fixed nut 7, and the movable screw rod 8 drives the positioning block 12 to slide through the push block 10, so that the positioning block 12 tightly fixes and positions the wire. During the tightening process, when the first rolling body 6 is in close contact with the inner wall of the receiving groove 5, and the second rolling body 14 is in close contact with the inner wall of the storage groove 13, the first rolling body 6 and the second rolling body 14 cannot rotate, and thus the wire will not slide during tightening. When the movable screw rod 8 is toggled to slide upward, at this time the movable screw rod 8 drives the positioning block 12 to gradually move away from the wire through the push block 10, so that the first rolling body 6 can rotate through the gap of the inner wall of the receiving groove 5 and the second rolling body 14 can rotate through the gap of the inner wall of the storage groove 13, and thus the wire can slide, which facilitates the adjustment of the tension of the guide wire, and further realizes the rapid adjustment of the wire without complete disassembly, improving the convenience of operation.

[0027] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
