By setting the modular frame 10, a stable connection device is provided for the entire connection device. The modular frame 10 has a fixed basic structure; several groups of mounting slots 11 symmetrically opened on the inner walls on both sides thereof can be adapted to the size of the mounting clips 21 at both ends of the cross frame 20 and slidably engaged, so that the cross frame 20 can be conveniently and quickly installed on the modular frame 10, thereby improving the installation efficiency; the main plug interfaces 14 opened at the four top corners of the modular frame 10 can be adapted to the size of the plug connectors 31 at the upper and lower ends of the main column 30 and plugged in, so that the main column 30 can be firmly installed at the four top corners of the modular frame 10, providing stable support for the entire structure; several groups of auxiliary plug interfaces 15 opened on the top surface of the modular frame 10 can be adapted to the size of the plug connectors 31 at the upper and lower ends of the auxiliary column 50 and plugged in, further enhancing the stability of the entire structure; at the same time, the through holes 13 opened on the outer walls of each group of main plug interfaces 14 and the mounting slots 11 can be used for installing bolts and other fixings to further strengthen the connection strength between the various components.
