Specifically, second slide grooves 18 are vertically arranged on the side walls on both sides of the mounting hole 20, and second sliding members 19 are correspondingly arranged on both sides of the upper sizing die 7. The second sliding member 19 is slidably connected to the second slide grooves 18. The first adjusting screw rod 5 adopts a hollow structure, and a threaded portion 15 is provided inside it. The second adjusting screw rod 6 is penetrated by the first adjusting screw rod 5 and is threadedly connected to the threaded portion 15. The bottom end of the second adjusting screw rod 6 passes through the slider 4 and is rotatably connected to the upper sizing die 7 to adjust the position of the upper sizing die 7. A mold 9 is provided in the upper sizing die 7 and the lower sizing die 8.

[0020] In one embodiment, both sides of the first slide groove 11 located on one side plate 10 are through-connected, and the first sliding member 12 is provided with a second threaded hole 16, and the second threaded hole 16 is threadedly connected to a fastening screw 17, and the fastening screw 17 passes through the first slide groove 11 in a horizontal direction. After adjusting the position of the slider 4 by the first adjusting screw 5, the fastening screw 17 is rotated so that the cap at its end abuts against the side plate 10, thereby further fixing the position of the slider 4.

[0021] In one embodiment, the base plate 2 is provided with extensions on both sides of the U-shaped plate 3, and the extensions are provided with positioning grooves 22 that pass through from top to bottom. The mounting frame 1 is set on a workbench, and the workbench is provided with a fixing plate 21. Positioning protrusions 23 are correspondingly provided on both sides of the fixing plate 21.

In order to quickly adjust the positions of the two groups of mounting frames 1, a positioning rod 25 is hinged on the top surface of the bottom plate 2 of one group of mounting frames 1, and a positioning bracket 26 is correspondingly arranged on the top surface of the bottom plate 2 of the other group of mounting frames 1. After the positioning grooves 22 of the two groups of mounting frames 1 are respectively inserted into the positioning protrusions 23, the positioning rod 25 is rotated to make the positioning rod 25 engage with the positioning bracket 26, so that the two groups of mounting frames 1 are aligned, and the two groups of mounting frames 1 are synchronously moved to the specified position, and the mounting frames 1 are fixed.

[0023] When the adjustable clamp for cable comprehensive protection is used, the mounting frame 1 is placed on the fixing plate 21, so that the positioning protrusion 23 is correspondingly inserted into the positioning groove 22, the positioning rod 25 is rotated to make the positioning rod 25 engage with the positioning bracket 26, and the two groups of mounting frames 1 are synchronously adjusted to the specified position, the first adjusting screw 5 is rotated to adjust the position of the slider 4, and the tightening screw 17 is tightened to strengthen the fixed slider 4. In the process of wrapping the aluminum-plastic composite strip material, the cable passes through the mold 9. Since the size of the joint is slightly larger than that of the cable, in order to ensure the continuity of production and processing, the second adjusting screw 6 is rotated to adjust the distance between the upper half sizing die 7 and the lower half sizing die 8. After the joint passes through the mold 9 smoothly, the second adjusting screw 6 is rotated again to adjust the distance between the upper half sizing die 7 and the lower half sizing die 8 to ensure the cable processing quality.
