The invention relates to an unlocking mechanical device, in particular to a device used for controlling and simulating opening of a door by manual labor in a contactless mode. The technical scheme adopted by the unlocking mechanical device is characterized in that a rotary oscillating arm is arranged on a motor shaft; an oscillating end of the rotary oscillating arm is connected with a handle clamp by means of a drag wire; a motor is controlled by cooperation with a relay; and in the way that axial motion of the motor is converted to up-down reciprocating motion, door-opening actions of a hand in the door can be simulated so that the door can be opened inside without a key by a contactless mode or a remote control module when no person exists inside the door. The unlocking mechanical device has following beneficial effects: by replacing a conventional mode of utilizing the key to unlock, the unlocking mechanical device is used for a special period of time in need of a temporary frequent permit allowing any person to go in and out; due to a simple structure, low production cost and a remote unlocking function, safety is improved and a solution for unified management of unlocking is provided; and the unlocking mechanical device is of great promotional value.
