The structure and supporting components of the limit cover 17 are the same as those of the limit cover 6. A movable slide groove 10 is opened on the end of the main frame 1 away from the side support frame 4, and an end fixing seat 11 is slidably connected in the movable slide groove 10. The end fixing seat 11 is equipped with an end clamping cover 13 for clamping and fixing the end position of the wiring harness.

[0025] Among them, a wiring harness placement groove 12 is opened on the end fixing seat 11, and an end limiting plate 15 is vertically arranged at the end of the end fixing seat 11 away from the side support frame 4. A top plate is arranged on the top of the end limiting plate 15, and a clamping and fixing cylinder 14 is fixedly installed on the top plate. The cylinder rod of the clamping and fixing cylinder 14 is fixedly connected to the upper end of the end clamping cover 13, and the clamping and fixing cylinder 14 is used to provide power support for the up and down movement of the end clamping cover 13.

[0026] The bottom of the end fixing seat 11 is fixedly connected to the movable nut seat 21 through a connecting plate 25, and the connecting plate 25 is snap-fitted and installed in the movable slide groove 10. The movable nut seat 21 is installed on the transmission screw 24.
