The wiring structure is composed of a wire box 3, a sorting piece 4, a tank chain 1 5 and a tank chain 2 6. The tank chain 1 5 and the tank chain 2 6 are used to protect the cables to prevent them from affecting their service life due to the exposed design.

[0027] The wiring box 3 includes a protective shell 31 arranged on the top outer wall of the base unit 1. The interior of the protective shell 31 is symmetrically provided with a partition 32 for cable grouping. A box cover 33 for pressing the top notch of the protective shell 31 is provided above the partition 32, and a wire pressing assembly 34 for pressing the cable is symmetrically provided at the bottom of the box cover 33. The symmetrical wire pressing assemblies 34 correspond to the separated spaces of the partition 32 respectively, so as to achieve stable limiting and fixing of the cables stored in the wiring box 3. The protective shell 31 has various shapes, and a U-shaped plate structure is adopted in this embodiment.

[0028] The basic unit 1 is composed of a base, a support frame and a stage. The support frame and the stage are both arranged on the top of the basic unit 1. The stage includes two stages, which are symmetrically distributed front and back to form two processing channels. The head units 2 include two, which are symmetrically connected to the front side of the support frame. The head units 2 correspond to the stage one by one. Each head unit 2 processes the material on the corresponding stage, thereby ensuring efficient processing of the material.

[0029] The arrangement piece 4, the tank chain 1 5 and the tank chain 2 6 each include two, wherein the two tank chains 1 5 are respectively mounted on the corresponding head unit 2. The two arrangement pieces 4 are respectively arranged on the corresponding tank chains 2 6, and the two tank chains 2 6 are symmetrically arranged inside the protective shell 31. Each tank chain 2 6 includes two strands, which are used to group and package the cables separated by the partition 32.

[0030] The finishing piece 4 is composed of a frame plate 41 and a cover plate 42. The side wall of the frame plate 41 is fixedly connected to the corresponding head unit 2, the cover plate 42 is installed on the top shell wall of the frame plate 41 by screws, and the bottom of the cover plate 42 is set at the top of the corresponding tank chain 2 6. Furthermore, when the head unit 2 is adjusted in displacement, the tank chain 2 6 is driven to move synchronously through the finishing piece 4, so as to ensure the stability of the displacement movement of the head unit 2.

[0031] The wire pressing assembly 34 includes a carrier plate 341 fixedly connected to the outer wall of the bottom of the box cover 33 by bolts.

And with the help of the adjustment tool, the bidirectional screw rod 342 in the wire pressing assembly 34 is adjusted to make it rotate. The rotation of the bidirectional screw rod 342 causes the moving seat in the support member 344 threaded thereon to be displaced, and then under the action of the support rod, the position of the wire pressing plate 343 is adjusted, and then the cables located in the wire box 3 are pressed and fixed, avoiding the overall movement adjustment of the cables when the head unit 2 is adjusted.
