[0075] Specifically, the load-bearing structures of the plug-in base I11, the plug-in base II12, the slot bracket I21 and the slot bracket II22 are made of a material with high rigidity, such as stainless steel.

[0076] like Figure 3 As shown, the present invention can be implemented by the following steps during installation:

[0077] First, the plug-in base assembly 1 is adjusted to a suitable width by pulling the plug-in base Ⅰ 11 and the plug-in base Ⅱ 12, and then the limit screw Ⅰ 13 is tightened to fix the width;

[0078] Secondly, the plug-in base assembly 1 is installed in the threaded hole reserved on the board through the oblong holes on both sides of the plug-in base I 11 and the plug-in base II 12 (i.e., the plug-in base I installation oblong hole (112) and the plug-in base II installation oblong hole (121));

[0079] Again, the slot bracket assembly 2 is adjusted to a suitable width by pulling the slot bracket I 21 and the slot bracket II 22, and then the limit screw II 23 is tightened to fix the width;

[0080] Finally, the slot bracket assembly 2 is installed in the threaded holes reserved on the chassis through the oblong holes on both sides of the slot bracket I 21 and the slot bracket II 22 (i.e., the slot bracket I installation oblong hole (212) and the slot bracket II installation oblong hole (222)). The threaded holes of the mounting panel on the chassis can also be used. At the same time, the pullers 3 at both ends of the plug-in base assembly 1 are pulled to realize the auxiliary extraction and auxiliary insertion functions.

[0081] The present invention innovatively designs a detachable and adjustable universal chassis plug-in device, changes the traditional chassis plug-in function directly designed on the board and chassis into a detachable device, and designs a slideway to achieve the adjustability of the device, thereby improving the versatility of the device. The present invention simplifies the plug-in function structure on the product into two threaded holes, providing more space for the miniaturized design of the chassis. The present invention has versatility through the design of the adjustable part, effectively reduces the chassis space occupied by the plug-in function, and improves the miniaturized design of the chassis.

[0082] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
