As the short rod moves, the second hemispherical block at this time abuts against the locking block. Under the pressure of the second hemispherical block, the locking block shrinks into the rectangular groove, and finally the locking block abuts against the arc surface of the second hemispherical block. At this time, the third spring is compressed, and the moving block is pushed to move under the action of the third spring. Under the limit of the locking block, the first hemispherical block abuts against the second hemispherical block. The third spring generates a thrust on the first hemispherical block and the second hemispherical block. Finally, the locking block shrinks into the rectangular groove, so that the first hemispherical block and the second hemispherical block are separated from the storage groove. In this way, the display frame can be disassembled. The operation is simple and quick without the help of tools.

[0017] In summary, the present invention can realize installation and disassembly of the installation frame by pressing, thereby improving the assembly efficiency of the installation frame, and also facilitating the later staff to inspect and replace the circuit board in the installation shell, and the operation is simple and convenient.
