The transmission component 7 drives the lever 8 on the travel switch 3 to displace. The lever 8 triggers the travel switch 3, and the power switch of the stranding machine 1 is turned off through the travel switch 3, so as to achieve the effect of automatic stop for wire breakage. The overall composition cost of the device is relatively low. Through the fastening mechanism 6 arranged around the metal stranded wire 2, the device has high sensitivity and is convenient to use.
[0024] In some specific embodiments, in order to monitor the state of the metal stranded wire 2, the fastening mechanism 6 includes a fastening ring 601, and the fastening ring 601 is fastened around the metal stranded wire 2; during use, the fastening ring 601 is fastened on the metal stranded wire 2, which is convenient for installation.

When a single wire in the metal stranded wire 2 breaks, the broken single wire will drive the fastening ring 601 to move, so as to trigger the travel switch 3 and realize the monitoring of the state of the metal stranded wire 2.
[0025] In some specific embodiments, in order to trigger the travel switch 3, the transmission assembly 7 includes a metal wire, which can be a copper wire. One end of the metal wire is connected to the guide plate 9 in a matching manner, and the other end is connected to the fastening ring 601 in a matching manner; when the broken single wire drives the fastening ring 601 to move, the fastening ring 601 will drive the transmission assembly 7 to displace, thereby driving the guide plate 9 to displace, and further triggering the travel switch 3 to complete the shutdown effect.
[0026] In some specific embodiments, in order to ensure the stability of the fastening ring 601 during implementation and ensure that the metal stranded wire 2 does not contact the inner wall of the fastening ring 601 during processing, a bracket 5 is provided below the fastening ring 601. The upper end of the bracket 5 is fixedly connected to the guide plate 9, and a guide groove 10 is provided on the guide plate 9. The bottom of the fastening ring 601 is fixedly connected with a slider 602 that is slidably matched with the guide groove 10, and a roller 603 that is matched with the guide groove 10 is provided at the bottom of the slider 602. The slider 602 can slide along the guide groove 10, so as to facilitate the movement of the fastening ring 601; after the fastening ring 601 is installed, the processed metal stranded wire 2 will pass through the inside of the fastening ring 601, and the bracket 5 will support the fastening ring 601 to ensure the stability of the fastening ring 601 and prevent the fastening ring 601 from shifting and contacting the metal stranded wire 2, affecting the use effect.

When the travel switch 3 needs to be used, the travel switch 3 can be erected and fixed by the locking assembly to maintain the working state of the travel switch 3.
[0028] In some specific embodiments, in order to fix the travel switch 3, the locking assembly includes a support frame 402 fixedly connected to the hinge base 401. A threaded rod 403 is rotatably connected to the support frame 402.
