1. the panel is provided with the abdicating hole, the baffle is provided with the screw hole which can be aligned with the abdicating hole, when the locking plate rotates to the horizontal position, namely the electric lock is in a locking state, the screw hole is aligned with the abdicating hole, at the moment, a lead sealing screw passes through the abdicating hole and is locked in the screw hole, namely lead sealing is realized, at the moment, the lock head, the lock core and the lock tongue are connected into a whole by the lead sealing screw, even if the lock body is partially damaged, the cabinet door or the cabinet door can be well locked, so that the electric lock can effectively prevent disassembly, and has the advantages of simple structure, convenient operation and low cost; compared with the lock tongue structure which only is a strip plate in the prior art, the electric lock is provided with the baffle plate, and the screw hole is formed in the baffle plate, so that the lead sealing screw cannot be screwed in under the condition that the lock tongue is not locked in place, the condition that the lead sealing screw is only screwed in part but an operator mistakenly thinks that the lead sealing screw is screwed in is avoided, and hidden dangers are reduced; moreover, after the jam plate rotated to the transverse position, first blockking the piece and making it can no longer continue to rotate to make the screw and not move after stepping down the hole and aim at, make the assembly of lead sealing screw more convenient, and first blockking the piece and the cooperation of second blockking the piece can also play the condition that prevents the rotatory dislocation of spring bolt, guarantee the normal use of electric lock.

2. The setting of spacing portion can further guarantee that the spring bolt can not rotate the dislocation.

3. The lock head is provided with the key hole in the shape of a straight line, the universality of the electric lock is enhanced, any similar key can be inserted into the lock head, a common straight screwdriver can be used as a temporary key, and the problem that the lock is damaged due to the fact that the key is forgotten in the field is greatly solved.
