1. A trigger type self-locking device for servers and rackmount cabinets, installed at an end of a slide rail moving section on a surface of a server, and the rackmount cabinet having a latch base fixed to a slide rail fixed section and provided for temporarily locking the slide rail moving section together with the server into the rackmount cabinet, comprising:
a trigger base, having a pivot part installed therein, the pivot part comprising a pin and a hole, a first opening formed on the trigger base under the pivot part, a second opening formed on the trigger base and at the front of the pivot part, and a stop block disposed between the second opening and the pivot part; and
a moving trigger, being substantially J-shaped, and having a pivot hole formed at a curved portion of the moving trigger for movably pivoting the pivot part, and the moving trigger having a pulling part disposed at an end extending downwardly along the pivot hole, and a snap hook disposed linearly at another end of the moving trigger and passed out from the second opening, and an elastic plate being installed between the snap hook and the pivot hole and extending obliquely along a bottom edge of the moving trigger, and the elastic plate is assembled on the stop block and limits the moving trigger, such that a linkage is formed after the moving trigger is assembled to the trigger base, and during operation, the snap hook is under the effect of restoring elastic force of the elastic plate, so that the moving trigger generates a reciprocating swing inside the trigger base to complete a locking connection with the latch base.
