This improves the accuracy and breadth of location queries, making it easier to locate and track livestock, thus enhancing the convenience and safety of livestock farming.

[0016] 2. This invention uses an adjusting wheel, a winding shaft, and a fixed gear to form a winding adjustment structure. Since one end of the tracking ring is fixedly connected to the inside of the winding block and the other end is fixedly connected to the outside of the winding shaft, rotating the adjusting wheel can drive the winding shaft to rotate and perform the pressing and winding process of the tracking ring, thereby adjusting the tension of the tracking ring.
