[0033] See also Figure 1-2 , a cable twisted wire clamp, including a shell and a clamping structure.

[0034] See also Figure 3-7 The outer shell includes a jacket 1, the upper part of the jacket 1 is a truncated cone structure with a larger upper part and a smaller lower part, and the lower part is a cylindrical structure. An inverted "convex"-shaped groove is provided at the upper end, and a circular through hole is provided at the lower end. The "convex"-shaped groove is provided with a thread in the cylindrical part. A safety plug 2 is threadedly connected to the upper end of the jacket 1. The upper end of the safety plug 2 is a vertical annular structure, and a thread is provided at the lower end, and cooperates with the thread provided on the above-mentioned jacket 1. Six fixing blocks 3 are fixedly installed at the lower end of the jacket 1, each fixing block 3 is provided with a circular through hole 2, and each fixing block 3 is rotatably connected to a shaft 4. A movable chuck 5 is inserted at the bottom of the jacket 1, and a T-shaped structure at the upper end of the movable chuck 5 is clamped in the jacket 1 through a through hole 1, and the upper end of the T-shaped structure of the movable chuck 5 is connected to the safety plug 2 The lower ends are in contact with each other. When the safety plug 2 is rotated, the movable chuck 5 also moves accordingly. By setting the safety plug 2 and fine-tuning this structure, the twisted wire chuck and the cable can be more closely matched together without damaging the cable. It also plays a role in fixing the chuck. The lower end of the movable chuck 5 is an inverted "convex" shaped geometric structure, and a groove 2 is provided at the bottom. The bottom end of the groove 2 is the cable inlet. Six evenly distributed long strip through holes 3 are provided on the side of the movable chuck 5. A reinforcement plate is fixedly installed between two adjacent through holes 3 on the side of the movable chuck 5. The function of the reinforcement plate is to make the movable chuck 5 stronger and not conducive to deformation and breakage damage. A number of fixers 6 are fixedly installed inside the movable chuck 5, and each fixer 6 is respectively fixed on both sides of the through hole 3.

[0035] See also Figure 8-9The clamping structure includes a dart-shaped lever 7, a portion of the dart-shaped lever 7 is located on the inner side of the movable clamp 5 through the through hole 3, and a portion of the dart-shaped lever 7 is located on the outer side of the movable clamp 5. The dart-shaped lever 7 is a labor-saving structure, and a small part of the force can be used to achieve strong clamping, thereby improving the fixing effect of the clamp. The dart-shaped lever 7 is sleeved with a No. 2 shaft 8, and the No. 2 shaft 8 is rotatably connected to the fixer 6. The upper end of the dart-shaped lever 7 is sleeved with a No. 3 shaft 10, and the No. 3 shaft 10 is plugged with a clamp 9. The side of the clamp 9 close to the central axis of the movable clamp 5 is a rectangular parallelepiped structure, and the side away from the central axis of the movable clamp 5 is a cylindrical structure. An anti-slip strip 11 is fixedly installed on the surface of the clamp 9 close to the center of the device axis. By setting the anti-slip strip 11, when clamping the cable, the contact area with the cable is increased, resulting in an increase in friction, which makes it more difficult for the cable to fall off. The end of the dart-shaped lever 7 away from the movable clamp 5 is sleeved with a No. 4 shaft 13, and the No. 4 shaft 13 is connected to the No. 4 shaft 13. The No. 1 axis 13 is connected with a pull rod 12, and the pull rod 12 is an arc-shaped structure. The arc-shaped structure also has the effect of saving effort, which is convenient for users to fix the cable. The dart-shaped lever 7, the clamp 9 and the pull rod 12 are all high-strength alloy structures. The upper end of the pull rod 12 is sleeved on the No. 1 axis 4. The No. 1 axis 4, the No. 2 axis 8, the No. 3 axis 10 and the No. 4 axis 13 are all dumbbell structures with large sides and a small middle. The No. 1 axis 4 is clamped with a fixing block 3 and a pull rod 12, the No. 2 axis 8 is clamped with a fixer 6 and a dart-shaped lever 7, the No. 3 axis 10 is clamped with a dart-shaped lever 7 and a clamp 9, and the No. 4 axis 13 is clamped with a dart-shaped lever 7 and a pull rod 12. By setting a clamping structure, the cable can be clamped more stably. The traditional clamping is fixed while moving at the same time. This structure is all-round movable to achieve cable fixation, and the clamping is more powerful. In addition, the use of a high-strength alloy structure greatly improves the stability of the device.

[0036] In summary, the cable twisted wire clamp, by providing the safety plug 2, can fine-tune this structure to make the twisted wire clamp and the cable fit more closely together without damaging the cable, and also play a role in fixing the clamp.

[0037] The cable strand clamp has six clamping structures to make the cable clamped more stably, and an anti-slip strip 11 is fixedly mounted on the clamp 9 to further reinforce the installation.

[0038] Working principle: When fixing the cable, first pass the cable through the groove 2 at the bottom of the movable clamp 5, so that the cable enters the inside of the movable clamp 5, then hold the sleeve 1 with one hand, hold the bottom end of the movable clamp 5 with the other hand, and then move the two hands away from each other. When it is obviously felt that they cannot be moved away, the clamp 9 is tightly fitted with the cable. At this time, tighten the safety plug 2. During the process of tightening the safety plug 2, the safety plug 2 pushes the movable clamp 5 downward. At this time, the movable clamp 5 and the sleeve 1 are away from each other, and then the clamps 9 are closed together through the clamping structure to achieve the effect of fine-tuning the clamping, and the use of threaded fine-tuning has the effect of saving effort, so that the clamping and fixing of the cable is completed.

[0039] 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.
