[0021] The drag chain mechanism 8 includes a connecting seat 801, which is connected to the second semicircular block 805 through the circular block 804 on the second semicircular block 803, so that the drag chain side plate 802 forms a drag chain effect, the outer wall of the connecting seat 801 is movably connected to the outer protective layer 7, the outer wall of the connecting seat 801 is fixedly connected to the drag chain side plate 802, the outer wall of the drag chain side plate 802 is fixedly connected to the first semicircular block 803, the inner wall of the first semicircular block 803 is fixedly connected to the circular block 804, the outer wall of the circular block 804 is rotatably connected to the second semicircular block 805, and the outer wall of the second semicircular block 805 is fixedly connected to the cover 806;

[0022] The chain support side plate 802 is assembled by inserting the round block 804 on the first semicircular block 803 into the second semicircular block 805. After multiple chain support side plates 802 are spliced ​​to form the shape of a drag chain, the cable formed by the multi-layer structure and the conductor 1 passes through the interior of the chain support side plate 802, and the second clamping block 902 on the rubber strip 901 is inserted into the clamping slot 11 at different positions of the kit 903. The same chain support side plates 802 on both sides are tightened relative to the center, and the space of the connecting seat inside the chain support side plate 802 is tightened and protected, so that the torsion and tension resistance of the chain support side plate 802 for multiple cables is improved.

[0024] Working principle:

[0025] By wrapping the conductor 1 with an inner insulating layer 2 and an outer insulating layer 6 made of tinned copper wire of the same material, the interference of the conductor 1 to the outside is reduced. In order to enhance the tensile effect, a fiber layer 4 made of glass fiber yarn is used to wrap an elastic band 5 with flexibility and tensile strength on the outside of the rubber insulation layer 3.
