[0038] In this embodiment, when the cable body 1 is bent, the spring sleeve 3 protects it, prevents excessive bending, and the two sets of abutting sleeves 4 abut and stretch the spring sleeve 3 at both ends, which is used to adjust the bending resistance of the cable body 1. Then, the forward rotation of the rotating sleeve 12 is transmitted by the gear ring 16 and the multiple gears 15, driving the multiple screw sleeves 13 to rotate and threadedly engage with the screw rods 14, so that the multiple screw rods 14 drive the sliding sleeve 10 to slide and push the multiple sliding blocks 7 along the slide rods 6 through the push ring 11. The multiple sliding blocks 7 drive the multiple wire binding plates 9 to abut against the outer wall of the protective sleeve 2, respectively. The multiple extension springs 8 can be used to clamp the cable body 1 with different diameters. The abutting ring 23 at the top of the sliding block 7 pushes the compression spring 22 to be stretched, and the protective sleeve 2 is clamped when the extension spring 8 is compressed. At this time, the contraction spring 20 pulls the limiting block to engage in the positioning hole 18, and the rotating sleeve 12 is positioned.

[0039] More specifically, when disassembly is needed, the rotating sleeve 12 is reversely rotated to drive the gears 15 to reversely engage through the gear ring 16, so that the screw sleeves 13 drive the screw rods 14 to push the sliding sleeve 10 and the push ring 11 to disengage the multiple sliding blocks 7. At this time, the abutting ring 23 is driven by the elastic reset of the compression spring 22 to push the multiple sliding blocks 7 to slide along the slide rods 6, so that the multiple wire binding plates 9 are disengaged from the protective sleeve 2. Then, the spring sleeve 3 can be adjusted.

[0040] In summary, when the overall device is in use or operation: when the cable body 1 is bent, the spring sleeve 3 protects it, prevents excessive bending, and the two sets of abutting sleeves 4 abut and stretch the spring sleeve 3 at both ends, which is used to adjust the bending resistance of the cable body 1. Then, the forward rotation of the rotating sleeve 12 is transmitted by the gear ring 16 and the multiple gears 15, driving the multiple screw sleeves 13 to rotate and threadedly engage with the screw rods 14, so that the multiple screw rods 14 drive the sliding sleeve 10 to slide and push the multiple sliding blocks 7 along the slide rods 6 through the push ring 11. The multiple sliding blocks 7 drive the multiple wire binding plates 9 to abut against the outer wall of the protective sleeve 2, respectively. The multiple extension springs 8 can be used to clamp the cable body 1 with different diameters. The abutting ring 23 at the top of the sliding block 7 pushes the compression spring 22 to be stretched, and the protective sleeve 2 is clamped when the extension spring 8 is compressed. At this time, the contraction spring 20 pulls the limiting block to engage in the positioning hole 18, and the rotating sleeve 12 is positioned.

[0041] When disassembly is needed, the rotating sleeve 12 is reversely rotated to drive the gears 15 to reversely engage through the gear ring 16, so that the screw sleeves 13 drive the screw rods 14 to push the sliding sleeve 10 and the push ring 11 to disengage the multiple sliding blocks 7. At this time, the abutting ring 23 is driven by the elastic reset of the compression spring 22 to push the multiple sliding blocks 7 to slide along the slide rods 6, so that the multiple wire binding plates 9 are disengaged from the protective sleeve 2. Then, the spring sleeve 3 can be adjusted.
