Firstly, the torsion block 127 abuts against the tilting rod 123, so that the torsion spring 124 is continuously in a deformed state, when the building platform needs to be used, the building platform is moved to a specified position, at this time, the space on the movable plate 8 and the sliding plate 5 is the working plane of the building platform, then the distance between the two guide frames 6 is adjusted according to the requirement, so that the working plane of the building platform is enlarged, the rotating rod 115 is rotated, the rotating rod 115 drives the bidirectional threaded rod 113 to rotate through the bevel gear 116 after rotating, under the action of the threaded matching of the two connecting frames 112 and the bidirectional threaded rod 113, the bidirectional threaded rod 113 drives the two movable plates 8 to move in the direction away from each other through the connecting frame 112, the two movable plates 8 respectively drive the guardrails 9 thereon to move together, the guide sleeve 10 cannot move along with the two movable plates 9, and simultaneously, the two guide frames 6 are pushed in the direction away from each other through the sliding block 7 after the two movable plates 8 move, the first spring 117 is compressed, so that under the action that the two moving plates 8 continuously move in the direction away from each other, the distance between the two guide frames 6 is gradually increased, thereby the working plane of the building platform can be enlarged, when the distance between the two guide frames 6 needs to be shortened later, the rotating rod 115 is rotated reversely by rotating the handle, the rotating rod 115 drives the bidirectional threaded rod 113 to rotate reversely through the bevel gear 116 after rotating reversely, the bidirectional threaded rod 113 drives the two moving plates 8 to move in the direction approaching each other through the connecting frame 112, the two moving plates 8 respectively drive the guardrails 9 thereon to move together, meanwhile, the two moving plates 8 do not push the two guide frames 6 through the sliding blocks 7 any more at this time, thereby the first spring 117 resets and drives the two guide frames 6 and the two sliding blocks 7 to move in the direction approaching each other, therefore, the working plane of the building platform can be adjusted to a proper size through the forward and reverse rotating rotary rods 115, when the outside of a window of a building needs to be constructed, the front side of the moving plate 8 faces the outside of the window, whether the working plane needs to be moved outside the window is selected according to actual requirements, when the working plane needs to be moved, a worker pushes the moving plate 8 forwards, the moving plate 8 drives the sliding plate 5, the guardrail 9 and the guide sleeve 10 to move forwards along with the moving plate 8, the sliding plate 5 moves onto the guide rail 132 in the process of moving forwards, then the moving plate 8 and the sliding plate 5 stop pushing after moving forward to proper positions, at this moment, the moving plate 8 and the sliding plate 5 move forwards outside the window, then the sliding pieces of the electric sliding rails 3 on the left side and the right side are controlled to move towards the directions away from each other, the sliding pieces of the electric sliding rails 3 on the two sides respectively drive the connecting rods 4 on the electric sliding rails to move towards the directions away from each other, the connecting rods 4 at two sides are expanded outwards and rotate towards the direction far away from each other by taking the rotating points on the base 1 as the circle centers, so that the supporting plate 2, the electric sliding rails 3, the sliding plate 5, the moving plate 8, the sliding blocks 7, the guardrails 9 and the guide sleeves 10 can be jacked up in the process that the connecting rods 4 at two sides rotate towards the direction far away from each other, the moving plate 8 and the sliding plate 5 can drive workers to move upwards, then when the sliding plate 5 needs to move downwards, the sliding parts of the electric sliding rails 3 at the left and right sides are controlled to move towards the direction close to each other, the sliding parts of the electric sliding rails 3 at two sides drive the connecting rods 4 thereon to move towards the direction close to each other along with the sliding parts of the electric sliding rails 3 at two sides, the connecting rods 4 at two sides are retracted inwards and rotate towards the direction close to each other by taking the rotating points on the base 1 as the circle centers, and the supporting plate 2 can be rotated towards the direction close to each other by the connecting rods 4 at two sides, the electric slide rail 3, the slide plate 5, the movable plate 8, the sliding block 7, the guardrail 9 and the guide sleeve 10 are pulled downwards, the movable plate 8 and the slide plate 5 can drive a worker to move downwards, so that the worker can lift the working plane of the building platform by controlling the moving direction of the sliding part of the electric slide rail 3, after the working plane is lifted to a proper height, the electric slide rail 3 is closed, and the worker can perform subsequent construction, in the construction process of the worker, the guardrail 9 can protect the worker to prevent the worker from falling from the building platform, and when the moved working plane needs to be retracted later, the worker lowers the movable plate 8 and the slide plate 5 by taking the electric slide rail 3 as a driving force, so that the support plate 2 is in contact with the base 1, then the electric slide rail 3 is closed, and the worker pushes the movable plate 8 backwards to reset, the moving plate 8 drives the sliding plate 5, the guardrail 9 and the guide sleeve 10 to move backwards, after the moving plate 8 and the sliding plate 5 move backwards and reset, the guide rail 132 is supported and the torsion block 127 is rotated, the torsion block 127 drives the screw rod 126 to rotate therewith, under the effect that the screw rod 126 is in threaded fit with the first threaded hole 128 and the second threaded hole 133, the screw rod 126 drives the torsion block 127 to move downwards together after rotating, the torsion block 127 does not abut against the tilting rod 123 any more after moving downwards, so that the torsion spring 124 resets and drives the front end of the tilting rod 123 to rotate downwards, the rear end of the tilting rod 123 rotates upwards and jacks the fixture block 125 upwards, the fixture block 125 blocks the sliding plate 5 after being jacked upwards, therefore, under the effect of the fixture block 125, the fixture block 125 can limit the sliding plate 5 when the sliding plate 5 does not move out, the sliding plate 5 is prevented from moving, and after the screw rod 126 is separated from the second threaded hole 133 during the random downward movement, the turning of the torsion block 127 is stopped, the guide rail 132 is taken down from the support plate 121, the two support frames 131 are finally turned backwards by 90 degrees and are folded, then the construction platform is used, then the guide rail 132 needs to be installed back on the support plate 121, and when the working plane needs to be moved forwards again, the guide rail 132 is placed back on the support plate 121, the second threaded hole 133 is aligned with the first threaded hole 128, then the torsion block 127 is turned backwards, the torsion block 127 drives the screw rod 126 to turn backwards along with the screw rod, the torsion block 127 is driven to move upwards together after the screw rod 126 turns backwards, the front end of the tilting rod 123 is pushed upwards after the torsion block 127 moves upwards, so that the rear end of the tilting rod 123 rotates downwards and pulls the clamping block 125 downwards, the torsion spring 124 deforms, then the screw rod 126 moves upwards and is inserted into the first threaded hole 128, and after the clamping block 125 no longer blocks the sliding plate 5, the turning of the torsion block 127 is stopped, finally the two support frames 131 are pulled forwards by 90 degrees, the support frames 131 can support the guide rail 132, then the moving plate 8 and the sliding plate 5 can be used for adjusting the working space and the construction platform according to the requirements and the requirements of the construction platform and the working plane can be expanded.
