[0036] As an embodiment of the present invention, two groups of steering columns 603 are provided and are symmetrically arranged with each other. One end of the steering column 603 passes through the steering plate 602 and is connected to the steering plate 602 through a bearing.

[0037] Among them, the steering column 603 is used to locate the rotation direction of the fastening clamp 601, and the steering plate 602 can rotate horizontally on the surface of the steering column 603 by bearing connection. The fastening clamp 601 and the steering column 603 are arranged one by one, and the fastening clamps 6 are close to each other, and the fastening clamps 601 at the same end of the positioning guide seat 4 and the movable guide seat 3 are close to each other.

[0038] As an embodiment of the present invention, one side of the fastening clamp 601 is a concave arc structure, the steering plate 602 is fixedly connected to the side surface of the fastening clamp 601 away from the concave portion, the restoring spring 604 is movably wound around the surface of the steering column 603, and the two ends of the restoring spring 604 are respectively fixedly connected to the side walls of the steering plate 602 and the steering column 603.

[0039] The concave surface of the fastening clamping plate 601 is equipped with a plurality of silicone anti-slip strips, and the restoring spring 604 limits the rotation angle between the steering column 603 and the steering plate 602, and can drive the steering plate 602 to automatically return to its original position under the action of elastic force, so that the fastening clamping plate 601 is always clamped on the surface of the cable in a natural state, and Figure 3 The fastening clamps 6 on the positioning guide seat 4 and the moving guide seat 3 are close to each other, and the fastening clamps 601 on the positioning guide seat 4 and the moving guide seat 3 are respectively close to each other, and the concave surfaces are close to each other, and the two are used to fix the cable, and due to the elastic force of the recovery spring 604, the fastening clamp 601 is in a clamping state on the cable surface.

When the extrusion clamp 605 is squeezed toward the middle of the movable guide plate 5, the guide block 606 is pulled to rotate, driving the fastening clamp 601 to flip along the steering column 603. The external force is adjusted to apply pressure to the restoring spring 604, which is convenient for increasing the distance between the two fastening clamps 6 and tightening the cable.

[0042] As an embodiment of the present invention, the movable guide seat 3 includes a movable slide 301, which is slidably connected to the surface of the movable guide plate 5. A fastener groove 303 is provided on one side of the movable slide 301 close to the positioning guide seat 4, and the fastening clamp 6 is installed in the fastener groove 303.

[0044] As an embodiment of the present invention, the locking frame 701 is a "U"-shaped structure. The two ends of the locking frame 701 near the opening are arranged to penetrate the movable guide seat 3. One end of the locking frame 701 that penetrates the movable guide seat 3 is respectively arranged on both sides of the movable guide plate 5. The end of the locking frame 701 that does not penetrate the movable guide seat 3 is rotatably connected with a rotating shaft sleeve 706. One end of the rotating shaft sleeve 706 penetrates the surface of the locking frame 701 and is rotatably connected to the locking frame 701. An internal thread groove is opened in the middle of the rotating shaft sleeve 706.

[0045] As an embodiment of the present invention, the reinforcement mechanism 8 includes a compression sleeve 801 and a threaded shaft 803, one end of the threaded shaft 803 movably passes through the internal thread groove and is fixedly connected to the surface of the movable guide seat 3, and the end of the threaded shaft 803 away from the movable guide seat 3 is fixedly connected to a positioning head block 804, the compression sleeve 801 is movably sleeved on the surface of the threaded shaft 803, and two spring pressure plates 802 are arranged between the compression sleeve 801 and the positioning head block 804.

[0046] The spring pressing piece 802 separates and compresses the sliding sleeve 801 and the positioning head block 804, and the threaded shaft 803 is threadedly connected with the internal thread groove.

[0047] As an embodiment of the present invention, the spring pressure sheet 802 is sleeved on the surface of the threaded shaft 803 and squeezes the compression sleeve 801. The compression sleeve 801 contacts the top of the rotating shaft sleeve 706. A sleeve groove 805 is opened on the surface of the positioning head block 804, and one end of the compression sleeve 801 is slidably connected in the sleeve groove 805.

[0048] Among them, Figure 7The compression sleeve 801 is wrapped around the surface of the two spring pressure sheets 802, and the spring pressure sheets 802 squeeze the compression sleeve 801 so that the compression sleeve 801 is supported on the top of the rotating shaft sleeve 706. When fixed, as the rotating shaft sleeve 706 pushes, it approaches the compression sleeve 801, and then squeezes the two spring pressure sheets 802. The spring pressure sheets 802 are subjected to pressure and deform, and then generate elastic force to push the rotating shaft sleeve 706 in the reverse direction, so that the rotating shaft sleeve 706 and the threaded shaft 803 are tightly matched to prevent the rotating shaft sleeve 706 from loosening.

[0049] As an implementation mode of the present invention, an anti-slip sleeve 704 is installed on the surface of the rotating shaft sleeve 706 , and the anti-slip sleeve 704 is arranged on the surface of the locking frame 701 .

[0050] The anti-slip sleeve 704 can be rotated to drive the rotating shaft sleeve 706 to rotate. When the rotating shaft sleeve 706 rotates, it moves up and down on the surface of the threaded shaft 803.

[0051] As an implementation manner of the present invention, an anti-skid pad 703 is installed on the top of the locking slider 702 , and a plurality of universal balls 705 are installed on the bottom of the locking slider 702 .

[0052] Among them, the upper and lower ends of the locking slider 702 are both provided with gaps with the upper and lower inner walls of the guide track groove. The locking slider 702 is fixedly connected with the locking frame 701. Figure 4 and Figure 6 When the locking frame 701 moves up and down, it drives the locking slider 702 to move up and down. When the locking slider 702 is driven to move upward, the anti-skid pad 703 on the top gradually approaches and contacts the top wall of the guide track groove, clamping the position of the moving guide seat 3 to prevent it from sliding. When it moves downward in the opposite direction, the universal ball 705 will approach the bottom, and then it can slide freely in the guide track groove to adjust the distance between the moving guide seat 3 and the positioning guide seat 4.

[0053] When tightening the cable, first rotate the shaft sleeve 706, drive the shaft sleeve 706 through the anti-slip sleeve 704, and then the shaft sleeve 706 drives the locking slider 702 to move up and down, so that the universal ball 705 contacts the guide track groove, and can freely slide and move the guide seat 3 to adjust according to the diameter of the cable;

[0054] After the position is determined, the anti-skid sleeve 704 is rotated in the opposite direction to pull the locking frame 701 up, so that the rotating sleeve 706 is close to the pressing sleeve 801, and the spring pressing piece 802 is squeezed to press the rotating sleeve 706. After the rotating sleeve 706 pulls the anti-skid pad 703 on the locking slider 702 close to the guide track groove, the rotation is stopped, and the pressing sleeve 801 is pressed tightly against the surface of the rotating sleeve 706;

[0055] When tightening the cable, place the connector plug between the tightening base plate 1 and the tightening base plate 2, and clamp the cable between the tightening clamps 6;

[0056] The two squeezing clamps 605 are squeezed to force the fastening clamps 601 to separate, increase the distance between the fastening clamps 601, and place the cable between the two. After relaxation, under the action of the recovery spring 604, the fastening clamps 601 approach the surface of the cable and clamp the surface of the cable. When the two ends are pulled, they can be clamped by the fastening clamps 601 to prevent separation after tightening.
