The invention relates to the technical field of positioning and tracking, and discloses a neck wearing type intelligent lamb tracker which comprises a buffer strip with bandages arranged on the two sides and a positioner assembly located on the inner side of the buffer strip, and two switching mechanisms symmetrically distributed and located on the two sides of the positioner assembly are arranged on the outer side of the buffer strip. Fixing frames are arranged on the two sides of the positioner assembly correspondingly, and the positioner assembly is rotatably connected with an adapter clamped into each switching mechanism through fixing pins fixedly connected into the fixing frames in a sleeved mode. According to the neck wearing type intelligent lamb tracker, through cooperative use of the fixing sleeve, the clamping block, the limiting groove and the adapter, the positioner assembly on the lamb tracker can be directly disassembled by rotating the adapter, replacement and installation of the positioner assembly are facilitated, meanwhile, through cooperative use of a limiting rod, an ejector rod and a spring, the lamb tracker can abut against the clamping block through the conical surface of the ejector rod, and the positioner assembly is prevented from falling off from the lamb tracker.
