The first spring 5 is fixedly mounted at the center of the inner bottom end of the circular groove 4. The sliding column 6 is fixedly connected to the end of the first spring 5 away from the bottom of the circular groove 4, and the sliding column 6 is slidably connected to the inner part of the circular groove 4. The semicircular pressing plate 7 is fixedly mounted to the end of the sliding column 6 away from the first spring 5.

[0033] Furthermore, two rectangular grooves 8 are correspondingly provided on the inner walls of the plurality of circular grooves 4, and two sliders 9 are slidably installed inside the rectangular grooves 8. The corresponding ends of the two sliders 9 are fixedly connected to the outer surfaces of the sliding column 6 on both sides, and the two sliders 9 are arranged at one end of the sliding column 6 close to the first spring 5. The cable is placed between the upper cable clamp 3 and the lower cable clamp 2, and the upper cable clamp 3 and the lower cable clamp 2 are threadedly connected together by bolts 18. The semicircular pressure plates 7 on both sides of the cable are squeezed to move backward, and the first spring 5 is deformed and compressed. Since the first spring 5 returns to its original state, the first spring 5 is deformed and rebounds, driving the sliding column 6 and the semicircular pressure plate 7 thereon to clamp and fix the cable and provide buffer protection for the cable. The mechanism for buffering and protecting the cable can absorb part of the pressure when the cable is clamped, reduce the direct squeezing of the cable sheath, thereby avoiding deformation or damage of the cable sheath, and can also effectively reduce the impact on the internal structure of the cable, prevent damage to the internal wires, and can also adapt to cables of different specifications and materials, so that the cable clamp has a wider range of applicability.

[0034] Furthermore, a mechanism for facilitating the removal of the lower cable clamp 2 includes a fixing block 16, an oblique limit block 13, a second spring 12 and a connecting rod 15. A groove 10 is provided on the upper surface of the support frame 1 corresponding to the position of the lower cable clamp 2. Slide grooves 11 are provided on the inner walls on both sides of the left and right sides of the groove 10. The two second springs 12 are respectively fixedly connected to the bottom of the slide groove 11. The two oblique limit blocks 13 are respectively fixedly connected to the bottom end of the second spring 12 away from the slide groove 11. The two oblique limit blocks 13 are both slidably connected to the inner wall of the slide groove 11.

[0035] Furthermore, the two slide grooves 11 are provided with straight slots 14 on the lower surface of the corresponding support frame 1, and the two connecting rods 15 are respectively fixedly connected to the lower surface positions of the corresponding oblique limit blocks 13 in the straight slots 14, and the two connecting rods 15 are slidably connected to the inner wall of the straight slots 14;

[0036] Furthermore, the fixing block 16 is fixedly installed at a position corresponding to the groove 10 on the lower surface of the lower cable clamp 2, and the fixing block 16 is slidably connected to the inner wall of the groove 10. Limiting grooves 17 are provided at positions corresponding to the oblique limiting blocks 13 on both sides of the fixing block 16, and the two oblique limiting blocks 13 are slidably connected to the inner walls of the limiting grooves 17.

[0037] Among them, the fixing block 16 is adapted to the groove 10, and the two oblique limit blocks 13 are adapted to the corresponding limit grooves 17. The fixing block 16 on the lower cable clamp 2 is inserted into the corresponding groove position on the support frame 1, and the fixing block 16 squeezes the oblique limit block 13. The oblique limit block 13 drives the second spring 12 to deform and compress, and the fixed block 16 continues to move downward. When the oblique limit block 13 corresponds to the position of the limit groove 17, the second spring 12 deforms and rebounds, and the oblique limit block 13 enters the limit groove 17, and the lower cable clamp 2 is clamped together with the support frame 1, limiting the movement of the lower cable clamp 2 on the support frame 1, making the disassembly process of the cable clamp easier, and the staff can easily remove the cable clamp from the support frame without using special tools or performing complicated operations, which simplifies the maintenance process, improves work efficiency, and makes daily maintenance and overhaul work more convenient.

The rubber anti-skid pads 19 have excellent anti-skid properties and can effectively increase the friction between the cable clamp and the cable to prevent the cable from sliding or falling off under external forces such as vibration and wind. The soft material of the rubber anti-skid pads 19 can reduce the wear and scratches on the cable sheath, avoiding unnecessary damage to the cable during the clamping process;

[0039] The upper cable clamp 3 and the lower cable clamp 2 are threadedly connected together via a bolt 18 at a side away from the hinge.

[0040] Working principle: When using this device, the fixing block 16 on the lower cable clamp 2 is inserted into the groove position corresponding to the support frame 1, and the fixing block 16 squeezes the oblique limit block 13. The oblique limit block 13 drives the second spring 12 to deform and compress, and the fixed block 16 continues to move downward. When the oblique limit block 13 corresponds to the position of the limit groove 17, the second spring 12 deforms and rebounds, and the oblique limit block 13 enters the limit groove 17, and the lower cable clamp 2 is clamped together with the support frame 1, limiting the movement of the lower cable clamp 2 on the support frame 1, making the removal process of the cable clamp easier. The staff can easily remove the cable clamp from the support frame without using special tools or performing complicated operations, which simplifies the maintenance process, improves work efficiency, and makes daily maintenance and overhaul work more convenient.

[0041] The cable is placed between the upper cable clamp 3 and the lower cable clamp 2, and the upper cable clamp 3 and the lower cable clamp 2 are threadedly connected together by bolts 18. The semicircular pressure plates 7 on both sides of the cable are squeezed to move backwards, and the first spring 5 is deformed and compressed. Since the first spring 5 returns to its original state, the first spring 5 is deformed and rebounds, driving the sliding column 6 and the semicircular pressure plate 7 thereon to clamp and fix the cable and provide buffer protection for the cable. The mechanism for buffering and protecting the cable can absorb part of the pressure when the cable is clamped, reduce the direct squeezing of the cable sheath, thereby avoiding deformation or damage of the cable sheath, and can also effectively reduce the impact on the internal structure of the cable, prevent damage to the internal wires, and can also adapt to cables of different specifications and materials, so that the cable clamp has a wider range of applicability.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
