Further, the height of the first D-shaped lacking block is smaller than that of the second D-shaped lacking block.
Furthermore, arc-shaped bolt locking portions are arranged on two sides of the semicircular lock hole of the bolt.
Furthermore, the support is a structure shaped like a Chinese character 'ji', and comprises a top plate, two side walls and two mounting wings, wherein the round holes are formed in the middle of the top plate, and a front baffle and a rear baffle are arranged at the front end and the rear end of the round holes of the top plate.
Furthermore, the edges of the rotating handles on the two sides of the lifting handle are provided with arc-shaped holding parts, and the two sides of the top surface of the lifting handle are respectively provided with an unlocking mark and a locking mark.
The module quick maintenance lock of the LED display screen has the advantages that: after the quick maintenance lock is assembled, when the module is maintained, the lock rod is pressed and rotated to unlock, and the lock rod is pressed and rotated back to lock and then released to lock; when the module is maintained after, the handle is lifted manually and locked quickly and rotated to unlock, and the handle is lifted and rotated back to rotate and then is released to lock, so that the technical effect that the front maintenance and the rear maintenance can be carried out is realized, and the operation convenience of the maintenance lock is improved by rotating to unlock the lock.
