The right side of the connecting plate 9 is fixedly connected to the right side of the inner wall of the squeezing ring 6. The squeezing ring 6 squeezes the automobile wiring harness 10, so that the connecting plate 9 inside the squeezing ring 6 squeezes the tightening spring piece 8 inside the sliding groove 7, so that the automobile wiring harness 10 passes through the inner side of the squeezing ring 6, and then the squeezing ring 6 is squeezed and contracted toward the direction of the transmission rod 2, so that automobile wiring harnesses 10 of different sizes are simultaneously limited in the rapid feeding inside the squeezed ring 6, so as to prevent the automobile wiring harness 10 from being scattered after being cut off and affecting the transportation;

[0040] An automobile wiring harness 10 is arranged on the inner side of the extrusion ring 6, and a cutter 11 is arranged on the top of the base plate 1. The cutter 11 is used to cut the automobile wiring harness 10.

The closing plate 16 can close the top of the support plate 141 to prevent the automobile wiring harness 10 from sliding out between the support plates 141, so that the automobile wiring harness 10 can be stably transported on the bottom plate 1; the top of the transmission rod 2 is threadedly connected with a protective plate 17, and the protective plate 17 is located at the top of the automobile wiring harness 10 The protective plate 17 can limit the automobile wiring harness 10 loaded between the extrusion rings 6 to prevent the automobile wiring harness 10 from moving out from the inner side of the extrusion ring 6 during loading; the top of the bottom plate 1 is fixedly connected to a limiting shell 18, the limiting shell 18 is located on the top of the synchronous belt 4, and the transmission rod 2 is movably connected to the inside of the limiting shell 18. The limiting shell 18 can cover the synchronous belt 4 to support the automobile wiring harness 10 on the inner side of the extrusion ring 6, so that the automobile wiring harness 10 is not easy to contact with the synchronous belt 4 and affect the transmission use of the synchronous belt 4.

[0043] Working principle: When the user uses it, the automobile wiring harness 10 of different sizes passes through the inner side of each extrusion ring 6. When the automobile wiring harness 10 passes through the inner side of the extrusion ring 6, the extrusion ring 6 is pushed by the connecting plate 9 under the pressing spring piece 8, so that the extrusion ring 6 connected to the connecting plate 9 applies different clamping forces according to the automobile wiring harness 10 of different sizes, so that the automobile wiring harness 10 of different sizes can be limited inside each extrusion ring 6 for feeding. When the motor 5 is started, the output end of the motor 5 is pre-connected with the bottom end of any transmission rod 2, so that the motor 5 drives a transmission rod 2 to rotate and drives the gear 3 on the surface of the transmission rod 2 to rotate. The gear 3 meshes with the inner wall of the synchronous belt 4, so that the gear 3 meshes with the synchronous belt 4 and drives the multiple gears 3 inside the synchronous belt 4 to rotate synchronously, so that the multiple gears 3 can rotate synchronously. The transmission rod 2 fixed with the gear 3 synchronously drives the multiple connecting plates 9 engaged by the sliding groove 7 with the 4 to rotate, so that the multiple connecting plates 9 drive the multiple extrusion rings 6 to limit the automobile wiring harnesses 10 of different sizes, and through the friction between the friction ring 13 outside the extrusion ring 6 and the automobile wiring harness 10, the multiple automobile wiring harnesses 10 of different sizes are rubbed on the inner side of the extrusion ring 6 and quickly loaded, thereby achieving the rapid loading and limiting of automobile wiring harnesses of different sizes, preventing the multiple automobile wiring harnesses from being scattered after being cut off, and the electric push rod 123 pushes the multi-position cutting plate 122 at the top of the fixing frame 121, so that the cutter 11 at the bottom of the multi-position cutting plate 122 moves down to cut the automobile wiring harnesses of different sizes loaded on the bottom plate 1, thereby achieving the cutting of automobile wiring harnesses of different sizes into different lengths.
