Anti-theft limiting safety device

The utility model discloses an anti-theft limiting safety device which comprises a baffle arranged at the front end of a conveying mechanism and a driving mechanism used for driving the baffle to retract and stretch out, the baffle is an eccentric baffle, the driving mechanism is a rotating motor, and the output end of the rotating motor is fixedly connected to the eccentric baffle. The rotating motor rotates to drive the eccentric baffle to stretch out or retract back at the front end of the conveying mechanism, and the rotating motor is arranged on one side of the eccentric baffle and can be further arranged below the conveying mechanism, so that the anti-theft limiting function can be achieved only by reserving an avoiding space of the eccentric baffle at a blocking position; therefore, the arrangement space of an original vertical lifting mechanism is greatly saved, the universality of the anti-theft limiting safety device is improved, the equipment size is reduced, and the product performance is improved
