[0025] The adjusting assembly 5 comprises a movable knob 51, a pulley set 52, a friction ring 53, a reset spring 54, a driving shaft 55, a driven shaft 56, a second worm 57, a second worm wheel 58 and a connecting rod 59. The movable knob 51 is movably arranged on the connecting seat 3, the pulley set 52 is movably arranged inside the connecting seat 3, the friction ring 53 is fixedly mounted on the movable knob 51, both ends of the reset spring 54 are fixedly connected to the driving shaft 55 and the movable knob 51 respectively, the driving shaft 55 is rotatably arranged on the connecting seat 3, the driven shaft 56 is rotatably arranged inside the connecting seat 3, the second worm 57 is fixedly mounted on the driven shaft 56 and is threadedly connected to the second worm wheel 58, the connecting rod 59 is fixedly mounted on the movable knob 51 and plugged into the driving shaft 55, and the driving shaft 5 5 is also connected to the driven shaft 56 through the pulley set 52, the driven shaft 56 is connected to the screw 43 through the pulley set 52, and the second worm wheel 58 is also connected to the screw 43 through the pulley set 52, so as to improve the flexibility of the overall structure, thereby ensuring the overall use efficiency and improving the efficiency of the overall steel structure turnover. The side of the friction ring 53 is provided with a friction pattern for enhancing friction and cooperating with the connecting seat 3, so that the overall structure is locked in an unmanned operation state, thereby ensuring the stability of the overall device to ensure the normal use of the elevator shaft platform. A hexagonal socket is provided on the end surface of the movable knob 51, and the hexagonal socket cooperates with a hexagonal wrench to facilitate the actual operation of the user and improve the practicality of the overall device.

[0026] Working principle: the two ends of multiple support rods 2 are welded to the connecting seat 3 and the platform plate 1 respectively to form an elevator shaft platform, and then the connecting seat 3 is placed at a right angle to the building, and the movable knob 51 is pressed down to make the friction ring 53 fixed on the movable knob 51 disengage from the connecting seat 3. At this time, the friction pattern on the friction ring 53 for enhancing friction does not contact and cooperate with the connecting seat 3, so the movable knob 51 can be rotated. Since the connecting rod 59 fixed on the movable knob 51 is in a plug-in relationship with the active shaft 55, the active shaft 55 will rotate with the rotation of the movable knob 51, and under the transmission of the pulley group 52, the driven shaft 56 rotates. The driven shaft 56 also uses the pulley group 52 to drive one of the screw rods 43 to rotate, and the second worm 57 fixed on the driven shaft 56 is threadedly connected with the second worm wheel 58. After the driven shaft 56 rotates, the second worm wheel 58 also drives the other screw rod 43 to rotate through the pulley group 52.

[0027] As the screw rod 43 rotates, the slide 42 threadedly connected to the screw rod 43 will slide inside the connecting seat 3, and the driving gear 44 set on the slide 42 will start to rotate under the drive of the auxiliary rack 45 as the slide 42 slides, and the driving gear 44 itself starts to rotate, and the driving gear 44 meshes with the differential gear 46, and the differential gear 46 meshes with the transmission gear 47. The first worm 48 fixed on the transmission gear 47 is threadedly driven by the first worm wheel 49 fixed on the transmission shaft 410, and the transmission shaft 410 is connected to the connecting bolt 41 by a bevel gear set 411. Therefore, under the transmission of such a structure, the connecting rod set on the slide 42 is rotated. The connecting bolt 41 slides with the sliding seat 42, and the connecting bolt 41 itself rotates synchronously. At this point, the connecting bolt 41 slides toward the building surface of the elevator shaft opening while rotating itself, and the entire structure can be connected and installed using the thread on the connecting bolt 41. At this time, the movable knob 51 is loosened again, and under the action of the return spring 54 fixedly connected to the movable knob 51 and the driving shaft 55 at both ends, the movable knob 51 slides upward, causing the friction ring 53 to contact with the connecting seat 3, so that the friction pattern on the friction ring 53 cooperates with the connecting seat 3 to increase the friction, so as to limit the rotation of the movable knob 51 and the driving shaft 55, thereby locking the overall structure and improving stability.
