[0006] To achieve the above object, the utility model provides the following technical scheme: a connecting mechanism for steel structure building, including the connecting main part, the connecting main part inner wall rotatory connection has two -way screw rod, two -way screw rod passes through the adjusting assembly and is connected with upper and lower both sides connecting plate, for adjusting the distance between upper and lower connecting plate, upper connecting plate left end and lower connecting plate right end are slidably connected in the connecting main part inner wall left and right two ends, the connecting plate top end is installed with a plurality of bolts, the connecting plate top end inner wall slidably connects with the limiting plate, the limiting plate outer wall is provided with closed assembly, for making limiting plate move to the top end of bolt.

[0007] Further, the adjusting assembly includes the moving block that is screw connected on the outer wall of the two-way screw rod on the front and back sides, the moving block upper and lower ends are rotatably connected with the support rod, and the other end of the support rod is rotatably connected with the opposite end of the connecting plate.

[0008] Furthermore, the closing assembly includes sliders fixedly connected to the front and rear ends of the limiting plate, and slide rods fixedly connected to the front and rear ends of the inner wall of the connecting plate, with the inner wall of the slider slidably connected to the outer wall of the slide rods.

[0009] Furthermore, a spring is sleeved on the outer wall of the slide rod, with the left end of the spring fixedly connected to the left end of the inner wall of the connecting plate, and the right end of the spring fixedly connected to the left end of the slider.

[0010] Furthermore, a knob is fixedly connected to the front end of the bidirectional threaded rod for driving the bidirectional threaded rod to rotate.
