[0024] The guide assembly 3 includes a guide rod 31 and a spring clip 32 . One end of the guide rod 31 is connected to the drive shaft 21 of the angle sensor 2 , and the other end of the guide rod 31 is connected to the spring clip 32 . The spring clip 32 is clamped with the bell mouth of the saddle 4 .
[0025] The traction pin 1 is provided with a groove 11 for accommodating the angle sensor 2 at one end close to the guide assembly 3, and a cover plate 12 is provided outside the groove 11. The cover plate 12 is fixedly matched with the groove 11 to fix the angle sensor 2 in the groove 11. The angle sensor 2 is communicatively connected with the electronic control system.
[0026] Specifically, the guide rod 31 of the guide assembly 3 includes an L-shaped first guide rod 311 and a second guide rod 312. The short end of the L-shaped first guide rod 311 is fixedly connected to the second guide rod 312 by bolts, and the long end of the L-shaped first guide rod 311 is fixedly connected to the drive shaft 21 of the angle sensor 2. The angle sensor 2 is located in the groove 11 of the traction pin 1 close to the first guide rod 311, and the angle sensor 2 is fixed in the groove 11 by the cover plate 12. The cover plate 12 is fixedly connected to the groove 11 of the traction pin 1 by bolts, and the second guide rod 312 is fixedly connected to the spring clip 32 by bolts, and the spring clip 32 is clamped at the bell mouth of the saddle 4. The end of the traction pin 1 away from the angle sensor 2 is fixedly connected to the trailer, and the saddle 4 is fixedly connected to the main vehicle. When the locking mechanism on the saddle 4 locks the traction pin 1, the spring clip 32 of the guide assembly 3 is clamped at the bell mouth of the saddle 4, and the main vehicle and the trailer are combined with each other; when the locking mechanism releases the traction pin 1, the traction pin 1 drives the guide assembly 3 to separate from the saddle 4, and the main vehicle and the trailer are separated from each other.

[0028] In the above structure, by arranging the angle sensor 2 and the guide assembly 3 in the traction pin 1 to cooperate with each other, the steering angle of the saddle 4 is accurately identified, thereby improving the accuracy of detection. One end of the guide rod 31 is directly connected to the angle sensor 2 in the traction pin 1 through an axis, thereby improving the efficiency of angle detection. The angle sensor 2 is arranged in the traction pin 1, which can effectively prevent the angle sensor 2 from being squeezed by other components, causing damage and other problems, thereby improving the service life of the angle sensor 2. The steering angle detection structure is not only simple in structure, but also improves the accuracy and efficiency of angle detection, ensures the driving safety of the main vehicle and trailer, and prolongs the service life of the equipment.

This arrangement facilitates the spring clip 32 to drive the second guide rod 312 and the first guide rod 311 to rotate when the saddle 4 rotates.
