In other embodiments, the sliding mechanism 200 can also be a slide groove and a slide rail that fit each other, the slide groove is arranged on the side walls on both sides of the installation cavity 10A, and the slide rail is arranged on the first side plate 113 and the second side plate 114, so that the slide rail slides in the slide groove, and reduces the friction force of the transfer box 100 inserted into the screen cabinet 10.

[0042] In an optional embodiment, as shown in FIG3 , the secondary equipment modification device further includes a locking mechanism 300, which is disposed between the side wall of the installation cavity 10A and the box body 110, and is used to lock the position of the adapter box 100. After using the sliding mechanism 200, the adapter box 100 is prone to slide due to low friction. By providing the locking mechanism 300, the position of the adapter box 100 can be limited, thereby preventing the adapter box 100 from sliding by itself, ensuring stable operation of the device, and improving the convenience of operating the adapter box 100.

[0043] Specifically, as shown in Figure 5, the locking mechanism 300 includes a fixed bracket 311, a connecting column 312, an elastic member 313 and a connecting plate 314, the connecting plate 314 is arranged on the screen cabinet 10, the fixed bracket 311 is arranged on the box body 110, the connecting column 312 is movably installed on the fixed bracket 311, the connecting column 312 is provided with an abutting portion 3121 and an unlocking portion 3122, the two ends of the elastic member 313 respectively abut the abutting portion 3121 and the bracket, the connecting plate 314 is provided with a locking hole 314A, the connecting column 312 can be movably inserted into the locking hole 314A, and a smooth surface 3123 is provided on one side of the connecting column 312 that is movably inserted into the locking hole 314A.

When the connecting column 312 slides to the locking hole 314A, the elastic member 313 drives the connecting column 312 to insert into the locking hole 314A, thereby completing the locking. When unlocking is required, the connecting column 312 can be released from the locking hole 314A by pushing the unlocking portion 3122, thereby releasing the adapter box 100 to slide, which has the advantage of convenient operation.
