[0067] The limiting structure 4 is provided with a boss 41;

[0068] The side of the rotating lock 31 is provided with a groove 312 corresponding in size to the boss 41;

[0069] The groove 312 can be clamped with the boss 41 when following the rotation of the rotating lock 31.

[0070] In this embodiment, the lower surface of the shell 21 is provided with two groups of mounting feet 25 of different sizes, and the shell 21 is fixedly installed on the bottom plate 1 through the mounting feet 25. The different sizes of the mounting feet 25 can realize the function of preventing wrong installation.

[0071] In this embodiment, the shell 21 is provided with a mounting shaft 26 parallel to the rotating shaft 23 and diagonally arranged. One end of the mounting shaft 26 is fixedly installed in the shell 21, and the other end is fixedly connected in the limiting cover 3, thereby enhancing the structural connection rigidity between the shell 21 and the limiting cover 3 and preventing stress deformation. The diagonal arrangement can better improve the torsional strength.

[0072] In this embodiment, the rotating seat 22 is a "V"-shaped sheet shape arranged around the rotating shaft 23. The part below the rotating shaft 23 is arranged in parallel on the bottom surface of the shell 21 and is fixedly installed on the bottom surface of the shell 21 through the reinforcing plate 27. The part above the rotating shaft 23 of the rotating seat 22 is an upturned sheet body with an included angle of 40°-45° with the bottom surface of the shell 21. A circular-arc-shaped threading groove 231 is arranged at the end of the upturned sheet body. The V shape forms a lever arm, which is convenient for operation. The stable foundation is formed by the part below the rotating shaft 23 close to the fixed point.

[0073] The reinforcing plate 27 significantly enhances the ability of the rotating seat 22 to resist deformation and looseness.

[0074] The upturned sheet body provides a natural cable supporting surface and a force application point.

[0075] The threading groove 231 positions and protects the cable, prevents it from sliding off or being subjected to shearing force from the end of the rotating seat, and the groove arc reduces the wear on the insulating layer of the cable.

[0076] In this embodiment, the rotating lock 31 includes a rotating part and a limiting part. The rotating part is located in the limiting cover 31, and the limiting part is located above the limiting cover 31. The rotating part is driven to rotate by the rotating seat, the limiting part presses down the upper part of the shell, and the rotating lock 31 and the rotating seat 22 are limited.

[0077] In this embodiment, the bottom of the limiting part is provided with a limiting inclined surface for pressing down the upper part of the shell 21.

[0078] In the embodiment, the limiting structure 4 comprises a vertical rod 42 and a horizontal plate 43, the bottom of the vertical rod 42 is fixedly installed on the bottom plate 1, and the horizontal plate 43 is fixedly installed on the top of the vertical rod 42, the horizontal plate 43 is made of elastic material, and the boss 41 can be pressed into the groove 312 through elasticity.

[0079] In the embodiment, the boss 41 is fixedly installed below the horizontal plate 43 through a connecting seat.

[0080] In the embodiment, the end of the horizontal plate 43 is provided with a push plate 44, after the wiring is completed, the push plate 44 is manually pushed to make the boss 41 out of the groove 312, the rotating seat 22 is released, and the cable is convenient to take out.

[0081] Working principle: at the beginning, the rotating seat 22 is in the lifted state, the upper flange body is lifted, and the blocking part at the upper end is located in the middle of the threading hole 24. At this time, the cable can be freely put into the threading groove 231 at the end of the rotating seat 22 through the opened threading hole 24, and when the cable is pushed inward, the rotating seat 22 is rotated around the rotating shaft 23 through the pressing of the cable itself, and the rotating lock catch 31 is synchronously rotated in the pressing process of the rotating seat 22, and after rotation, the groove 312 is clamped with the boss 41. When the groove 312 is rotated in place, the groove 312 is clamped below the boss 41, and the two are tightly combined, the shell 21 is pressed, and the cable is fixed through the pressure, forming double constraints of the structure resistance of the rotating seat itself + the physical clamping of the lock catch, which strongly prevents the accidental springing up of the rotating seat 22 and the disengagement of the cable.

[0082] When the cable needs to be replaced or adjusted, the operator pushes the push plate 44 at the end of the limiting structure horizontal plate 43 with fingers or tools, the groove 312 is lifted to disengage the boss 41, at this time, the constraint is removed, the rotating lock catch 31 is no longer locked by the downward pressure, the cable is released by reversely pushing the rotating lock catch 31, the upper and lower parts of the shell are opened, and the cable can be taken out.

[0083] It is known from common technical knowledge that the present application can be realized through other embodiments without departing from the spirit or essential characteristics thereof. Therefore, the above-mentioned disclosed embodiments are only examples in all aspects, and are not the only ones. All changes within the scope of the present application or within the scope equivalent to the present application are included in the present application.
