The arc-shaped pressing plate 5 in the clamping assembly is limited by the clamping assembly, so that it can clamp the U-shaped snap ring 3, thereby ensuring the limiting effect of the cable. During the installation process, the arc-shaped pressing plate 5 in the clamping assembly only needs to be pressed down to engage with the clamping assembly to complete the installation, which is convenient and quick.

[0018] In a specific embodiment, the clamping assembly includes an arc-shaped pressing plate 5 adapted to the U-shaped snap ring 3, the arc-shaped pressing plate 5 is a rubber plate, the middle of the arc-shaped pressing plate 5 is in contact with the top of the U-shaped snap ring 3, and the two sides of the arc-shaped pressing plate 5 are provided with protrusions 6 corresponding to the slide grooves 4.

Each slide groove 4 is provided with a clamping assembly, and the clamping assembly is clamped with the protrusions 6. The protrusions 6 are clamped by the clamping assembly, so that the arc-shaped pressing plate 5 clamps the multiple U-shaped snap rings 3. The rubber plate has a certain elasticity, which is convenient for pressing down the arc-shaped pressing plate 5 during the installation process to make it clamped with the clamping assembly.

[0019] In a specific embodiment, the clamping assembly includes a receiving groove 7 provided on the bottom wall of the slide groove 4, a square tube 8 is slidably connected in the receiving groove 7, a trapezoidal block 9 is slidably connected in the square tube 8, the cross section of the trapezoidal block 9 is a right-angled trapezoid, the inclined surface of the trapezoidal block 9 faces upward, one end of the trapezoidal block 9 with the inclined surface passes through the side wall of the square tube 8 and is in contact with the top surface of the protrusion 6, a compression spring 10 is fixedly connected between the other end of the trapezoidal block 9 and the side wall of the square tube 8, and an adjustment assembly for controlling the position of the square tube 8 is provided on the top of the side wall of the wire clamp body 1. Under the action of the compression spring 10, one end of the trapezoidal block 9 is located outside the square tube 8, and when the arc pressure plate 5 moves downward again, it first contacts the inclined surface of the trapezoidal block 9 to push the trapezoidal block 9 back into the square tube 8, and then when the top surface of the protrusion 6 is lower than the bottom surface of the trapezoidal block 9, the trapezoidal block 9 pops out under the action of the compression spring 10 to clamp the arc pressure plate 5.

[0020] In a specific embodiment, the adjustment assembly includes a threaded rod 11 corresponding to the square tube 8, the bottom end of the threaded rod 11 penetrates the side wall of the wire clamp body 1 and is located in the receiving groove 7, the threaded rod 11 is threadedly connected to the wire clamp body 1, the bottom end of the threaded rod 11 is rotatably connected to the top surface of the square tube 8, the top end of the threaded rod 11 is located at the top of the wire clamp body 1, and the top end of the threaded rod 11 is fixedly connected to the adjusting nut 12. The threaded rod 11 is driven to rotate by the adjusting nut 12 to adjust the position of the square tube 8, thereby adjusting the position of the trapezoidal clamping block 9 so that it can be adjusted according to the size of the protrusion 6.
