The invention discloses a portable
fingerprint lock. The portable
fingerprint lock comprises a face shell, a bottom shell, a steel wire and a
fingerprint identifier, wherein LED indicator lamps and atransparent lampshade are arranged on the periphery of the fingerprint identifier. A circuit board
assembly is arranged inside the fingerprint identifier, and a
lithium battery is arranged between thecircuit board
assembly and the bottom shell. The circuit board
assembly is provided with an MCU processor and a
buzzer. A speed reducing motor is arranged on one side of the face shell, a
cam is arranged on a shaft of the speed reducing motor, the speed reducing motor is internally provided with a lock clamp which can rotate from the lock hole in a rotating mode, and the lower part of the lock clamp is provided with a
torsion spring. One end of a lock hole is a round hole, the other end of the lock hole is a slightly-narrow flat hole, and the flat hole communicates with the round hole. One end of the steel wire is fixed on the surface shell and the bottom shell, the other end of the steel wire is fixedly connected with a spherical head, the spherical head is inserted into the lock hole, and the spherical head is clamped into the semi-arc end of the lock hole. A sliding block is arranged on the upper portion of one side of the lock clamp, and the two ends of the sliding block are of anarch structure, the front end of the sliding block abuts against the lock clamp, and the rear end of the sliding block abuts against a stop block arranged in a fixing seat groove. The portable fingerprint lock is novel and unique in structure, simple, convenient and practical, low in cost and high in reliability.
