Through research and analysis, it is found that the device is connected between the fixed seat and the connecting seat by a card ball, and the card ball can rotate in the card hole inside the connecting seat. When the connecting seat needs to be tilted, it can be slightly rotated with the card ball. After the rotation is completed, the two sets of support columns under the connecting seat can be screwed up to fix the angle. However, the following disadvantages still exist to a certain extent.

[0004] For example, when the equipment is in use, it is impossible to adjust the supporting components of the equipment, and there is no function to adjust the number of supporting structures. If the equipment has a large load-bearing capacity, it is easy to cause the equipment to have insufficient support force, which will greatly accelerate the wear of the equipment. In order to solve the above technical problems, we have designed a large-span riveted load-bearing large steel structure. Utility Model Content
