Abstract

The invention relates to an antitheft device. The antitheft device comprises positioning nuts and antitheft bolts, all of which are arranged at the bottom of a box. A box cover is fixed to the positioning nuts through the antitheft bolts. Elastic pieces are transversely arranged at the bottoms in the positioning nuts. A groove hole is formed in the center of each antitheft bolt. Marbles are transversely arranged at the bottoms of the antitheft bolts, one ends of the marbles correspond to the elastic pieces, and the other ends of the marbles stretch out of the groove holes. The antitheft device further comprises a T-shaped installing piece, the lower portion of the installing piece is inserted and connected into the corresponding groove hole, and the upper portion of the installing piece is buckled to the top of the corresponding antitheft bolt. The antitheft device is reasonable in structural design and low in cost, workers can conduct mounting and dismounting conveniently, stealers cannot loosen the antitheft bolts through staggered contact of the marbles and the positioning nuts, the antitheft coefficient is very high, and the antitheft device is worthy of wide popularization and usage.
