[0013] 2. The present invention adopts a height guide adjustment mechanism. The rotating cap drives the adjusting screw to rotate. The adjusting screw drives the threaded sleeve to move upward under the action of the thread transmission force. The threaded sleeve drives the linkage plate to move upward. The concave block enables the mounting top plate to move upward. The two mounting top plates can be adjusted in a staggered manner according to different heights, so that the two mounting top plates are not adjusted synchronously. In this way, different heights can be adjusted for support use, and the height tilt adjustment has a wider applicability.

[0029] The working principle of the H-shaped steel with height adjustment function of the present invention is as follows: First, when the present invention performs linkage adjustment, the rotating cap 5 is rotated, and the rotating cap 5 drives the linkage screw 3 to rotate. The linkage screw 3 rotates inside the guide frame 2, and at the same time, the linkage screw 3 drives the two articulated sleeves 4 to move away from each other under the action of the thread transmission force, so that the distance between the two articulated sleeves 4 becomes larger, the articulated sleeve 4 moves to the left, and the other articulated sleeve 4 moves to the right.

[0030] At the same time, the hinged sleeve block 4 drives the support shaft 6 to move left, and the support shaft 6 drives the bottom end of the sleeve rod 7 to move left. At the same time, the sleeve rod 7 drives the connecting shaft 8 to rotate counterclockwise, and the connecting shaft 8 drives the hinged block 9 to rotate counterclockwise, while the other connecting shaft 8 rotates clockwise. In this way, the hinged block 9 makes the sleeve plate 10 rotate counterclockwise, and the sleeve plate 10 rotates counterclockwise along the outer wall of the support rod 12. The steel body 1 can provide support force for the support rod 12 to increase the stability of the support rod 12. While the sleeve plate 10 can rotate counterclockwise to adjust the angle, the other sleeve plate 10 can rotate counterclockwise to adjust the angle.

[0031] Secondly, when the present invention performs height guide adjustment, by rotating the rotating cap 22, the rotating cap 22 drives the adjusting screw 14 to rotate, and the adjusting screw 14 rotates inside the support frame 13. At the same time, the adjusting screw 14 drives the threaded sleeve block 15 to move up under the action of the thread transmission force, and the threaded sleeve block 15 slides along the inner wall of the support frame 13. At the same time, the threaded sleeve block 15 drives the linkage plate 16 to move up, and the linkage plate 16 makes the concave block 17 move up, and the concave block 17 makes the mounting top plate 18 move up, and the mounting top plate 18 performs height adjustment operation, so that the two mounting top plates 18 can be offset and adjusted according to different heights, and the two mounting top plates 18 can be adjusted synchronously, so that different heights are adjusted for support use.

[0032] Then, when the present invention is engaged and locked, the locking cap 30 is rotated by a wrench, the locking cap 30 causes the locking screw 25 to rotate, the locking screw 25 rotates inside the sliding frame 24, and the locking screw 25 drives the linkage sleeve 26 to move backward under the action of the thread transmission force, and at the same time the linkage sleeve 26 drives the linkage block 27 to move backward, the linkage block 27 causes the pressure strip 28 to move backward, the pressure strip 28 drives the extrusion tooth plate 29 to move backward, and the extrusion tooth plate 29 is squeezed and locked along the meshing position of the two racks 23, so that the two hinged sleeves 4 can be locked to complete the adjustment and locking operation.

[0033] Finally, when the present invention is installed and docked, multiple bolts are inserted into the holes of the mounting plate 11, and the mounting plate 11 and the installed steel structure are docked and locked by the bolts, and then the bolts are inserted into the multiple mounting holes 19, so that the mounting top plate 18 is docked with another steel structure at the bottom to complete the installation operation.
