For the assembly and pre-welding device for I-beams, by inserting the vertical pipe into one of the connecting grooves, and then rotating the screw a downward and moving it, the hemispherical block can be driven to move downward, so as to drive the two sliders to move away from each other into the annular wall groove in cooperation with the semi-circular groove, so that the positioning mechanism a can be connected to the connecting groove, and thus the user can randomly rotate and adjust the angle of the positioning mechanism a on the bottom plate.

An I-beam can be placed through the positioning frame 705. Then, by rotating the rotating strip 703 back and forth and using the bolt b 704 for fixation, the angle and position of the positioning frame 705 can be adjusted according to requirements. Then, the I-beam is inserted into the positioning frame 705, and thus the I-beam can be fixed, facilitating the user to position the I-beam according to different requirements.

[0021] During use, the first step: Insert the vertical pipe 502 into one of the connecting grooves 2, and then rotate the moving screw a 503 downward. This can drive the hemispherical block 504 to move downward, thereby driving the two sliders 505 to move away from each other into the annular wall groove 9 in cooperation with the semi-circular groove 509. In this way, the positioning mechanism a 6 can be connected to the connecting groove 2, and the user can freely rotate and adjust the angle of the positioning mechanism a 6 on the bottom plate 1. The positioning mechanism a 6 can be fixed through the fixing mechanism 3. By installing the cutting device on the mounting plate 10 and the user installing the positioning mechanism a 6 at the edge of the bottom plate 1, the user can place the I-beam in the two L-shaped strips 603 for cutting.

[0023] Step 3: Connect the positioning mechanism a6 to the connection groove 2 through the connection mechanism 5. After adjusting the angle of the positioning mechanism a6, rotate the moving screw c302 downward, so that the flexible plate 303 can be driven to press the bottom plate 1, thereby generating a reaction force to fix the positioning mechanism a6.

[0024] Step 4: The extrusion of the hemispherical block 504 causes the two sliders 505 to move away from each other into the annular wall groove 9. At the same time, the two small blocks 508 can be driven to move away from each other, thereby compressing the compression spring 506. When the moving screw a503 is rotated upward, the rebound of the compression spring will drive the slider 505 into the chute 5010 through the small block 508, so that the user can move the positioning mechanism a6 upward to remove it, thus avoiding the situation where the slider 505 is stuck and the positioning mechanism a6 cannot be removed.

[0025] Step 5: The positioning mechanism b7 can be fixed on the bottom plate 1 through the connection mechanism 5 and the fixing mechanism 3. The I-beam can be placed through the positioning frame 705, and then fixed by rotating the rotating bar 703 back and forth and using the bolt b704. In this way, the angle and position of the positioning frame 705 can be adjusted according to the needs. Then, the I-beam is inserted into the positioning frame 705 to fix the I-beam, so that it is convenient for the user to position the I-beam according to different needs.
