The invention discloses an adjustable face recognition instrument convenient to disassemble. The adjustable face recognition instrument convenient to disassemble comprises a bottom plate, a connectingplate is fixedly connected to the upper surface of the bottom plate, two transverse plates are fixedly connected to the upper surface of the connecting plate, sliding grooves are formed in the uppersurfaces of the transverse plates, sliding blocks are arranged in the sliding grooves, and the upper surfaces of the two sliding blocks are fixedly connected with the lower surfaces of baffles correspondingly. According to the adjustable face recognition instrument convenient to disassemble, by arranging the baffles, a telescopic device, a sliding rod, a sliding sleeve, a rotating shaft and a first bearing, when a face recognition instrument body needs to be overhauled, an electrical pushing rod is controlled to work, thus the electrical pushing rod extends and retracts to drive a clamping block to move downwards, thus the first bearing is not clamped by the clamping block any more, meanwhile, workers manually pull the two baffles to be away from each other, thus the workers disassemble the face recognition instrument body conveniently, the situation that the workers disassemble the face recognition instrument body through tools is not needed, thus the time and physical strength of theworkers are saved, and the working efficiency of the workers is improved.
