The connecting column 8 is an inverted L-shaped block and the size of the top angled end of the connecting column 8 is adapted to the opening part of the card-mounted socket 4. A locking socket 2 9 corresponding to the inner diameter of the locking socket 1 5 is opened inside the angled end of the connecting column 8. After the angled end of the connecting column 8 is snapped into the inside of the card-mounted socket 4, the positions of the locking socket 1 5 and the locking socket 2 9 correspond.

[0026] The working principle of this utility model:

[0027] By providing an adjustable mounting armrest 6, the mounting armrest 6 is inserted into the inside of the mounting slot 2 and then a bolt is used to pass through the limiting hole 11 to dock and insert into the corresponding alignment slot 10 for locking. The entire mounting armrest 6 is movably installed in the inside of the mounting slot 2. Elastic gaskets 14 are provided on the surfaces of the two mounting armrests 6 close to each other on the same side. After the external cable is connected and installed with the two side terminals of the display body 1, the two mounting armrests 6 are adjusted to be close to each other so that the two elastic gaskets 14 are pressed against the surface of the cable. Then, the fastening bolts 13 are horizontally forked between the corresponding two connection holes 12 and rotated to keep the two elastic gaskets 14 pressed against the surface of the cable. The surfaces of the two elastic gaskets 14 are made of rubber material, and the friction force increases during squeezing. The cable and the terminal are kept connected during long-term installation to prevent the connection part between the cable and the terminal from loosening, thereby achieving a better fixing effect.

[0028] By providing a mounting base 7 for support, the two connecting columns 8 are moved close to each other on the surface installed on the mounting base 7, and then the top angle end of the connecting column 8 is inserted into the interior of the connecting cavity 3 through the card-mounted socket 4 and pushed. When the position of the locking hole 2 9 corresponds to the position of the locking hole 1 5, the bolt is inserted into the interior of the locking hole 1 5 and rotated and inserted into the locking hole 2 9 to lock. After the installation of the mounting base 7 is completed, the entire display body 1 can be supported. When storing the display body 1, the entire display body 1 can also be lifted through the inside of the installation handrail 6, and it becomes very convenient to move the display body 1, which greatly improves the installation convenience of the entire device.
