A pressing plate 508 is provided on one side of the movable plate 405, which is slidably connected to the fixed rod 506. A second spring 510 is installed between the pressing plate 508 and the connecting plate 509. A negative pressure adsorption member 512 is installed on the clamping cylinder 507. Two second connecting rods 511 are symmetrically hingedly installed on the side of the movable plate 405 away from the pressing plate 404. One end of the pressing plate 508 passes through the interior of the movable storage base 1, and the other ends of the two second connecting rods 511 are hinged to the two pressing plates 508 respectively. When the movable plate 405 moves toward the side of the pressure plate 404, the two pressing plates 508 are driven to move toward the side of the connecting plate 509 through the two second connecting rods 511, and the connecting plate 509 is fixedly connected to the clamping cylinder 507, and the end of the clamping cylinder 507 contacts the side wall of the guide plate 502, so that the second spring 510 is compressed. Under the elastic force of the second spring 510, the two clamping cylinders 507 press the guide plate 502, further improving the stability of the construction platform 2.

[0034] The negative pressure adsorption member 512 includes a piston 5121 fixedly mounted inside the clamping cylinder 507, an end rod 5122 fixedly mounted on the side of the piston 5121 away from the guide cylinder 501, the end of the end rod 5122 passes through the outside of the clamping cylinder 507, and a first tooth plate 5123 is fixedly mounted on one end of the end rod 5122. A second tooth plate 5124 is provided below the first tooth plate 5123, and the second tooth plate 5124 is fixedly connected to the pressing plate 508.

When the pressing plate 508 moves toward the connecting plate 509, it drives the second tooth plate 5124 to move, and drives the first tooth plate 5123 to move toward the side away from the guide cylinder 501 through the gear 5125, and then pulls the piston 5121 to move toward the side away from the guide cylinder 501, so that negative pressure suction is generated between the clamping cylinder 507 and the surface of the guide plate 502. The higher the height of the construction platform 2, the greater the negative pressure suction of the clamping cylinder 507 on the guide plate 502, thereby further improving the stability of the construction platform 2.

[0035] Working principle: During work, workers go to the top of the construction platform 2 to carry out construction. When height adjustment is required, the control motor 305 is turned on, causing the double-headed screw 304 to rotate. Since the two sliding seats 302 are respectively threadedly connected to the two thread grooves on the double-headed screw 304 with opposite directions, the two sliding seats 302 are driven to move closer to each other, thereby driving the two supporting links 303 to rotate, pushing the construction platform 2 downward to perform lifting and lowering adjustment;

[0036] When the height of the construction platform 2 is adjusted to the desired position, the control electromagnet 413 is energized, so that the electromagnet 413 generates a repulsive force on the magnetic block 412, thereby pushing the transverse plate 408 downward, and then pushing the two movable plates 405 closer to each other through the first connecting rod 409, and the pressing plate 404 contacts the side wall of the supporting link 303, so that the first spring 407 is compressed. Under the elastic force of the first spring 407, the pressing plate 404 presses the supporting link 303, thereby improving the stability of the movable storage base 1;

[0037] When the construction platform 2 moves upward, the conductive slider is driven upward by the adjusting rod 402, so that the resistance of the sliding rheostat 401 connected to the circuit decreases. As the height of the construction platform 2 increases, the repulsive force generated by the electromagnet 413 on the magnetic block 412 increases. As the height of the construction platform 2 increases, the clamping strength of the supporting link 303 is adaptively adjusted, thereby improving the stability of the construction platform 2.

[0038] When the construction platform 2 moves longitudinally, the guide plate 502 moves relative to the guide cylinder 501. When the movable plate 405 moves toward the pressure plate 404, the second connecting rod 511 pushes the pressure plate 508 toward the connecting plate 509. The end of the clamping cylinder 507 contacts the side wall of the guide plate 502, causing the second spring 510 to be compressed. The two clamping cylinders 507 clamp and press the guide plate 502, further improving the stability of the construction platform 2.

[0039] When the pressure plate 508 moves toward the side of the connecting plate 509, it drives the second tooth plate 5124 to move toward the side of the second fixed plate 505, and the second tooth plate 5124 engages with the bottom of the gear 5125, thereby driving the gear 5125 to rotate, thereby driving the first tooth plate 5123 to move toward the side away from the guide cylinder 501, thereby pulling the piston 5121 to move toward the side away from the guide cylinder 501, so that negative pressure suction is generated between the clamping cylinder 507 and the surface of the guide plate 502, and the higher the height of the construction platform 2, the greater the negative pressure suction of the clamping cylinder 507 on the guide plate 502, further improving the stability of the construction platform 2.
