through the structure, partial supporting capacity of the moving plate 25 can be provided, the supporting strength of the bracket to the top surface of the building is further enhanced, four telescopic rods 29 are fixedly arranged at the four corners of the bottom surface of the top, therefore, a movable range can be provided for the gap between the top seat 28 and the moving plate 25, the supporting force of the top seat 28 can be enhanced by using the compression spring A30, the bracket can be prevented from being damaged due to the hard contact between the top seat 28 and the top surface of a building in the lifting process, the service life of the bracket is prolonged, when the bracket is used for supporting the top surface of the building, a constructor can stand in the manned basket 36 and drive the rotating shaft 48 and the two winding wheels 52 thereon to rotate by using the servo motor B50, the spacing between the winding wheels 52 and the winding post 54 can be reduced by winding the metal soft rope 53 by the winding wheels 52, so that the manned basket 36 can be lifted upwards along the sliding fit direction of the limiting block 46 and the limiting groove 47, the constructor can easily and quickly utilize the structure to achieve the effect of assisting lifting, and can also automatically adjust the height according to the construction requirements, the convenience of the bracket is increased, the bracket is more humanized to use, the flexibility is enhanced, therefore, workers do not need to manually build and climb scaffolds which are time-consuming and labor-consuming, the safety guarantee is enhanced, the practicability is strong, during the period, when the workers climb the manned basket 36, the poke rod 42 can be firstly moved along the rod groove 43 so that the insert block 39 moves rightwards along the block groove 41 and is not clamped with the slot 40 any more, at the moment, the workers can open the movable door 38 and stand in the manned basket 36, after the workers release the poke rod 42, the poke rod 42 and the insert block 39 can restore the original position again under the resilience of the compression spring B44, and the movable door 38 can be automatically closed under the resilience force of the torsion spring 37 at the same time, and then under the impact force of the left end of the front wall of the manned basket 36 on the left end of the rear wall arc part of the insert block 39, can make the inserted block 39 pressed into the block groove 41 once more and can't block closing of dodge gate 38, when dodge gate 38 reverted to the initial position, the fixed of dodge gate 38 and manned basket 36 is accomplished in inserting slot 40 again under compression spring B44's elasticity effect to inserted block 39, utilize this structure, can effectually avoid constructor to forget the problem of closing the door after stepping into manned basket 36, easy and simple to handle need not a large amount of complicated connection steps, only need through poker rod 42 alright light and easy order manned basket 36 to seal, great improvement the security of this support, make constructor utilize this support to carry out construction operation to the eminence when abundant life safety guarantee.
