Test and anti-theft device for envelope of computer

The utility model relates to a test and anti-theft device for envelope of computer. The front face of the envelope is provided with a monitoring base board and a monitoring lock device. The monitoring base board is provided with an inductive optics component, a plurality of groups of state indicating lamps used for displaying the testing state, a signal transmitter, a buzzing output joint, and a signal input connector. Wherein, the inductive optics component and the testing board convex-equipped on the cover board correspondingly shield the inductive signals; the signal input connector is connected to a touch switch in the monitoring lock device through a row of wires to control the inductive optics component to conduct the monitoring detection; when the envelope of computer is monitored and locked, both the testing board on the cover board and the inductive optics component can be used to conduct the corresponding shield induction, and the lock action of the lock device can be used to realize the anti-theft and monitoring actions; when the envelope of computer is forced to be disassembled under the monitoring state, the inductive optics component can be touched to generate signals to the monitoring base board, and the signal transmitter can be triggered to be on line with the safe monitoring system to announce the warning.
