The working principle of the invention is as follows:

in the initial state, the optical fiber 200 is connected with the upper emission port, the contact on the contact group III 404 is contacted with the contact on the contact group I402, so that the optical fiber transceiver module 101 positioned above is normally used, the local area network is normally used, in addition, the contact on the contact group III 404 is not contacted with the contact on the contact group II 403, so that the optical fiber transceiver module 101 positioned below is thoroughly disconnected from the power supply, no connection exists, and the optical fiber transceiver module 101 positioned above is intact in the normal use process of the optical fiber transceiver module 101 positioned above;

when the local area network is disconnected due to the fact that the optical fiber transceiver module 101 located above is damaged when the optical fiber transceiver module is used for a long time and cannot be used, if the situation is detected by the detection plate, a signal is sent to the telescopic piece 317, the trigger plate 306 is driven to move through the telescopic piece 317, if the situation cannot be detected by the detection plate, a worker in an enterprise factory directly presses a button to enable the trigger plate 306 to move, and in the moving process of the trigger plate 306:

firstly, the protruding pin 305 pushes down on the inclined plane of the first chute bottom to move away from the first flat chute bottom, the first spring 304 is compressed, the protruding pin 305 moves through the connecting bracket 301 to move together with the middle plug 104, the middle plug 104 moves together with the optical fiber 200 to enable the optical fiber 200 to be pulled out of the upper emission port, then, the protruding pin 305 moves down under the traction of the second chute bottom, and further, the middle plug 104 moves down together with the optical fiber 200 to enable the optical fiber 200 to be aligned with the lower emission port, and then, at three positions of the chute bottom, the first spring 304 releases elastic force to enable the protruding pin 305 to move close to the second flat chute bottom to enable the optical fiber 200 to be inserted into the lower emission port;

meanwhile, the trigger plate 306 moves to push the convex rod 408 to move through the switching rod 318, so that the contact on the contact group III 404 is disconnected from the contact on the contact group I402 and is contacted with the contact on the contact group II 403, the optical fiber transceiver module 101 positioned below is electrified, and the local area network is recovered and can be used normally;

after the working time, when the local area network is disconnected and normal operation of an enterprise factory is not affected, maintenance is performed on the optical fiber transceiver module 101 positioned above by a maintenance person, and after the maintenance is finished:

pressing the button again to move the trigger plate 306, wherein in the process, under the extrusion of the two groups of inclined planes, the two groups of clamping blocks 313 and the sliding blocks 311 move away from each other, the second spring 312 is compressed, and when the clamping blocks 313 are positioned at the notch of the unlocking groove 308, the third spring 314 releases the elastic force again to enable the clamping blocks 313 to extend into the unlocking groove 308;

then, when the button is released, the fourth spring 303 releases the elastic force to move the trigger plate 306, and the limiting component 310 does not limit the movement of the trigger plate 306 due to the existence of the inclined groove wall, and when the clamping block 313 contacts with the side face of the limiting section 3062 of the trigger plate 306 again, the second spring 312 releases the elastic force to move the two groups of clamping blocks 313 and the sliding block 311 close to each other, the limiting component 310 resets, in this process, the optical fiber 200 is reinserted into the upper emission port, and the contact on the third contact set 404 contacts with the contact on the first contact set 402 again, that is, the optical fiber transceiver is restored to the initial state.

The present invention is not limited to the above embodiments, but is capable of modification and variation in detail, and other modifications and variations can be made by those skilled in the art without departing from the scope of the present invention.
