Novel spider electronic tag

Abstract

A novel spider electronic tag includes a take-up device; and a base connected to the take-up device through a retractable steel wire rope. The take-up device includes: a housing; a take-up assembly, mounted in the housing; and a locking fastener, mounted in the housing and configured to lock the take-up assembly; the locking fastener includes: a rotating ratchet member, fixedly arranged at the top of the take-up assembly; and a leaf spring, embedded in an inner circumferential wall of the housing and configured to cooperate with the rotating ratchet member to lock the take-up assembly. The steel wire rope is passed in a listed sequence through the rotating ratchet member, the take-up assembly and the base clockwise from top to bottom, and two ends of the steel wire rope are fixed inside the rotating ratchet member, to connect the take-up device with the base.
