The implementation principle of the adjustable less-bracket steel truss segment assembly auxiliary device of this embodiment is as follows:

First, the staff places the first steel truss beam 3 on the upper movable plate 5, and then places the second steel truss beam 4 on the bottom of the inner cavity of the concave base 1. At this time, the staff controls the motor 2 to operate through the controller, so that the motor 2 can drive the first threaded rod 8 and the second threaded rod 9 to rotate, and the thread directions of the first threaded rod 8 and the second threaded rod 9 are opposite, so the first threaded sleeve 10 and the second threaded sleeve 13 can be driven to move horizontally with the assistance of the first slide groove 14 and the first slider 15 in the first sliding mechanism, so that the first threaded sleeve 10 and the second threaded sleeve 13 can move away from each other;

When the first threaded sleeve 10 and the second threaded sleeve 13 move, the connecting plate 11 can be driven to move, and the L-shaped plate 12 can be driven to move by the connecting plate 11, so that the L-shaped plate 12 can drive the moving plate 5 to move, so that the first steel truss 3 can be located at the top. At this time, the staff can place the third steel truss 7 in the clamping grooves provided in the first steel truss 3 and the second steel truss 4, so that the plug-in can be completed;

When the staff needs to reduce the number of the first steel trusses 3, the staff turns the rotary knob 22 to allow the rotary knob 22 to rotate, thereby driving the third threaded rod 24 to rotate, so that the third threaded rod 24 can drive the threaded sleeve 23 to move upward. When the threaded sleeve 23 moves upward, the secondary steel truss 20 can be driven to move through the rotating assembly. Therefore, under the pulling force of the secondary steel truss 20, the guide slider 18 in the second sliding mechanism can slide on the guide slide groove 17, thereby entering the moving slide groove 30, so that the two secondary steel trusses 20 and the third steel truss 7 are a whole. Therefore, the reduction of steel trusses can be achieved, and the steel trusses can also be conditioned. The steel trusses are more convenient to assemble, and the steel trusses can be strengthened at any time when they need to be strengthened by unfolding the secondary steel trusses 20.
