When the cantilever steel beam 2 is installed on the overhanging layer 1, the reset plate 22 contacts the upper surface of the overhanging layer 1, the reset plate 22 is displaced into the reset groove 21, and the first spring 27 is stressed and shrinks. When the cantilever steel beam 2 is installed on the overhanging layer 1, the reset plate 22 is completely displaced into the reset groove 21.

[0032] By controlling the rotation of the threaded rod 45, the limiting sliding block 46 can be displaced downward or upward under the transmission of the threaded groove 47, when the contact top block 7 is in contact with the outer surface of the cantilever layer 1, the limiting sliding block 46 is displaced downward, and the lower side is clamped into the limiting groove, so that the limiting sliding block 46 can form a fixing effect on the contact top block 7, and the firmness after the installation of the support inclined rod 6 is further improved.

[0036] When the first toothed plate 65 is in contact with the inner wall of the transverse sliding groove 63, the contact top block 7 is in contact with the outer surface of the cantilever layer 1, at this time, the lower side of the limiting slider 46 is not displaced into the limiting groove on the top of the contact top block 7, and the reset plate 22 is not completely displaced into the reset groove 21, so the second toothed plate 66 is continuously displaced to the side close to the folding groove 5, at this time, the inner slide plate 68 is displaced in the retracting cavity 67, and the first tension spring 610 is stressed and stretched, the limiting slider 46 is continuously displaced downward under the transmission of the threaded rod 45, so that the lower side of the limiting slider 46 is displaced into the limiting groove, when the cantilever steel beam 2 is removed and the second toothed plate 66 is displaced to the side away from the folding groove 5, the first toothed plate 65 remains stationary under the pulling of the first tension spring 610, the inner slide plate 68 slides in the retracting cavity 67, and at this time, the threaded rod 45 drives the limiting slider 46 to displace upward, so that the lower side of the limiting slider 46 is displaced out of the limiting groove, through the above structure, the limiting slider 46 will not block the rotation of the supporting inclined rod 6, thereby ensuring the smoothness of the installation of the supporting structure.

When the limiting slider 46 is displaced downward, the contact push rod 413 slides on the vertical inner wall of the swing groove 415. When the contact push rod 413 slides to the inclined surface of the swing groove 415, the inclined surface of the swing groove 415 forms a pushing force on the contact push rod 413, so that the contact push rod 413 pushes the third tooth plate 412 to displace away from the vertical support 4. At this time, the third tooth plate 412 is engaged to drive the fourth gear 411 to rotate counterclockwise, and the inclined support plate 49 rotates upward. When the lower side of the limiting slider 46 is displaced into the limiting groove, the contact push rod 413 slides onto the side surface of the limiting slider 46. At this time, the inclined support plate 49 is rotated to be perpendicular to the support inclined rod 6.

The end of the pushing rod 493 outside the inclined support plate 49 is in contact with the inclined surface of the trigger push block 495.

[0040] When the inclined support plate 49 rotates upward, the pushing rod 493 rotates synchronously with the inclined support plate 49. When the pushing rod 493 is displaced to be in contact with the inclined surface of the trigger push block 495, the inclined surface of the trigger push block 495 forms a pushing force on the pushing rod 493, so that the pushing rod 493 pushes the extension leg 491 to displace close to the support inclined rod 6. At the same time, the third tension spring 494 is stressed and stretched. When the inclined support plate 49 stops rotating, the extension leg 491 is in contact with the outer surface of the support inclined rod 6, thereby forming a support effect on the support inclined rod 6, improving the stress intensity of the support inclined rod 6, and ensuring the stability and firmness of the support structure in use.

[0044] When the extension leg 491 moves to the side close to the support diagonal rod 6, the trigger push rod 4917 moves synchronously with the extension leg 491, when the trigger push rod 4917 moves to contact the inclined surface of the jacking block 4916, the jacking block 4916 extrudes the trigger push rod 4917, so that the trigger push rod 4917 moves to the trigger cavity 4915, at this time the rotating plate 4918 extrudes the connecting push rod 4913, so that the connecting push rod 4913 pushes the synchronous plate 4912 to move to the side close to the fifth gear 4910, and the fourth tension spring 4914 is stressed and stretched, when the extension leg 491 moves to the side of the push cavity 492, the trigger push rod 4917 moves out of the jacking block 4916, and does not limit the synchronous plate 4912, so that the fourth tension spring 4914 can pull the synchronous plate 4912 to move to the side away from the fifth gear 4910.
