[0028] Please see Figure 1-12 The present invention provides a technical solution: Example

[0029] A hydraulic tension clamp connecting fitting includes a connecting frame 1. Two inclined grooves are formed at the top and bottom of the inner cavity of the connecting frame 1. Two limiting plates 10 are provided within the inner cavity of the connecting frame 1, and the two limiting plates 10 are fitted together. A groove is formed on one side of each of the two limiting plates 10. A slider 12 is fixedly connected to the top and bottom of the limiting plates 10 near the left side. The slider 12 is movably connected to the inner cavity of the adjacent inclined groove. Connecting rods 8 are inserted into the front and rear sides of the connecting frame 1 near the right side. A T-shaped plate 3 is fixedly connected to the end of the connecting rod 8 away from the connecting frame 1. A rectangular frame 2 is fitted onto the outer edge of each T-shaped plate 3. A first spring 9 is fixedly connected to the left side of each T-shaped plate 3. The left end of the first spring 9 is fixedly connected to the left side of the inner cavity of the rectangular frame 2. A limiting mechanism is provided within the inner cavity of the connecting frame 1.

[0030] Two fixing blocks 13 are fixedly connected to the top of the connecting frame 1 near the right side. Each fixing block 13 has two through slots in its inner cavity. Two elastic cloths 14 are fixedly connected to the bottom of the connecting frame 1 near the right side. The side of the elastic cloth 14 away from the connecting frame 1 passes through the two adjacent through slots. The outer edges of the elastic cloth 14 are fixedly connected with hook and loop fasteners 17 and hook and loop fasteners 18. The hook and loop fasteners 17 and hook and loop fasteners 18 are fitted together. Each elastic plate 4 has a limiting hole near the right side of its inner cavity. A double threaded rod 6 passes through both limiting holes. Nuts 7 are threadedly connected to the outer edges of the double threaded rod 6 near the front and rear sides. An elastic ring 5 is fitted on the outer edges of the two elastic plates 4. An adjustment hole is opened on the front and rear sides of the elastic ring 5. The adjustment hole is fitted on the outer edge of the double threaded rod 6. The nut 7 is located between the elastic plate 4 and the elastic ring 5.

[0031] The angle of the connecting frame 1 can be adjusted. The hook on the utility pole is placed on the center of the surface of the double-threaded rod 6. The double-threaded rod 6 is then passed through the two elastic plates 4. After that, the elastic ring 5 is placed on the elastic plate 4 and the double-threaded rod 6, thereby installing the device and improving its applicability. Example

[0032] The limiting mechanism includes two U-shaped plates 25, which are arranged one behind the other. The U-shaped plates 25 are located between the limiting plate 10 and the inner cavity sidewall of the connecting frame 1. Several fixed helical teeth 11 are fixedly connected to the side of the limiting plate 10 closest to the U-shaped plates 25. The fixed helical teeth 11 are located in the inner cavity of the U-shaped plates 25. Several grooves are opened on both the front and rear sides of the inner cavity of the connecting frame 1. Movable helical teeth 24 are inserted into the grooves. Spring plates 15 are fixedly connected to the sidewalls of the grooves. One side of the spring plate 15 is fixedly connected to the side of the adjacent movable helical tooth 24. The U-shaped plates 25 are attached to the movable helical teeth 24. On one side of the tooth 24, through holes are provided near the four corners of the inner cavity of the U-shaped plate 25. A fixing post 26 is inserted through each through hole. The end of the fixing post 26 away from the limiting plate 10 is fixedly connected to the inner wall of the connecting frame 1. A third spring 27 is sleeved on the outer edge of the fixing post 26. The end of the third spring 27 away from the limiting plate 10 is fixedly connected to the inner wall of the connecting frame 1. The end of the third spring 27 near the limiting plate 10 is fixedly connected to one side of the U-shaped plate 25. A handle 16 is fixedly connected to the right side of the U-shaped plate 25. An anti-slip sleeve is sleeved on the outer edge of the handle 16.

[0033] The limiting plate 10 has clamping plates 19 on both the left and right sides. The two adjacent clamping plates 19 are fitted together. The top and bottom of the inner cavity of the clamping plate 19 have two connecting holes. An elastic rod 23 is inserted through the two adjacent connecting holes. The front and rear ends of the elastic rod 23 are fixedly connected to the fixing plate 21. The outer edge of the elastic rod 23 is fitted with a second spring 22 near the front and rear sides. The end of the second spring 22 away from the clamping plate 19 is fixedly connected to the side of the fixing plate 21. The other end of the second spring 22 away from the fixing plate 21 is fixedly connected to the side of the clamping plate 19. The outer edge of the clamping plate 19 is fixedly connected with two elastic ropes 20. The end of the elastic rope 20 away from the clamping plate 19 is fixedly connected to the side of the limiting plate 10.

[0034] The wire is placed between the two limiting plates 10. The limiting plates 10 move inside the connecting frame 1 via the slider 12, thereby clamping and limiting the wires of different diameters. The clamping plate 19, together with the elastic rod 23 and the second spring 22, further clamps and limits the wire. The fixed helical teeth 11, together with the movable helical teeth 24, can limit the position of the limiting plates 10. The elastic cloth 14, together with the hook and loop fastener barbed surface 17 and the hook and loop fastener napped surface 18, further limits the limiting plates 10.

[0035] Working principle: The operator picks up the device, moves the elastic plate 4 to the hook on the utility pole, places the hook between the two elastic plates 4, then passes the double-threaded rod 6 through the hook and the two elastic plates 4, rotates the two nuts 7 to the front and rear sides of the double-threaded rod 6, and then puts the elastic ring 5 on the surface of the double-threaded rod 6 and the two elastic plates 4 to install the device. Then, press the handle 16, which drives the U-shaped plate 25 to move. The U-shaped plate 25 drives the third spring 27 to compress, and the U-shaped plate 25 drives the movable helical tooth 24 to rotate. The movable helical tooth 24 drives the spring 15 to compress, rotating the movable helical tooth 24 to the groove on the inner wall of the connecting frame 1. Then, move the two limiting plates 10 to the right. The limiting plates 10 drive the slider 12 to move, and the limiting plates 10 drive the fixed helical tooth 11 to move. Pass one end of the wire through the adjacent clamping plate 19 and the two limiting plates 10. The clamping plate 19, together with the elastic rod 23 and the second spring 22, clamps the wire. Then, move the two limiting plates 10 to the left. The two limiting plates 10 will gradually approach each other, thereby clamping and limiting the wire again. After the two limiting plates 10 clamp the wire, release the handle 16. The U-shaped plate 25 moves away from the movable helical tooth 24. The movable helical tooth 24 returns to its original position through the spring 15. The fixed helical tooth 11 on the limiting plate 10 will contact the movable helical tooth 24, thereby limiting the limiting plate 10 and preventing the limiting plate 10 from falling off the right side of the connecting frame 1. Then pull the elastic cloth 14. The elastic cloth 14 is stretched through the fixing block 13, and the Velcro nap 18 on the elastic cloth 14 is attached to the Velcro barbed surface 17 on the elastic cloth 14. The elastic cloth 14 can further limit the limiting plate 10, improving the limiting effect of the device. At the same time, the angle and position of the connecting frame 1 can be adjusted. The connecting frame 1 and the connecting rod 8 are plugged in. The rectangular frame 2, together with the first spring 9, can adjust the position of the connecting frame 1, improving the applicability of the device.
