Then, the pins 18 are inserted into the corresponding limiting holes 19 to limit the position of the two expansion plates 15. The two expansion plates 15 can fill the gap between the two ends of the support platform 2 and the two ends of the inner wall of the elevator shaft, thereby expanding the support platform 2 and making it more practical. With the setting of the stabilizing plate 20, when the device is installed, the stabilizing plate 20 can extend out of the elevator opening to provide stable support for the support platform 2, thus making it more stable.

[0027] Example 2, as Figures 1-5As shown, the driving structure 3 comprises a motor 301 arranged at the bottom end of the body 1, the output end of the motor 301 penetrates the inner bottom wall of the body 1 and is fixed with a screw rod 302, the outer wall of the screw rod 302 is threadedly connected with a moving plate 303, both ends of the moving plate 303 are slidingly connected with limiting columns 304, both sides of the top end of the moving plate 303 are fixed with connecting blocks 305, the top ends of the two connecting blocks 305 penetrate the body 1 and are fixed with the supporting platform 2, the buckle structure 22 comprises a support 2201 fixed at the top end of the supporting platform 2, the support 2201 is slidingly connected with a clamping column 2202, the bottom end of the clamping column 2202 penetrates the stabilizing plate 20 and is arranged in the supporting platform 2, the top end of the clamping column 2202 is fixed with a top plate 2203, the spring 2204 is fixed between the top plate 2203 and the support 2201 outside the clamping column 2202, one end of the second ladder stand 9 is fixed with a second mounting plate 12, one end of the body 1 is fixed with a third mounting plate 13 matched with the second mounting plate 12, the second mounting plate 12 is fixed with the third mounting plate 13 through a second bolt 14, both sides of the end of the second ladder stand 9 facing the first ladder stand 8 are fixed with first limiting blocks 10, both sides of the end of the first ladder stand 8 facing the second ladder stand 9 are provided with first limiting grooves 11 matched with the first limiting blocks 10, both ends of the expansion plate 15 and the stabilizing plate 20 are fixed with second limiting blocks 16, the supporting platform 2 is provided with second limiting grooves 17 matched with the second limiting blocks 16, the top ends of the two connecting blocks 305 are fixed with first mounting plates 5, the two first mounting plates 5 are fixed with the supporting platform 2 through first bolts 6, the bottom end of the body 1 is fixed with a fixing frame 4, the motor 301 is arranged at the end of the fixing frame 4 facing the body 1, the top end of the screw rod 302 is rotationally connected with the body 1, both ends of the limiting column 304 are fixed with the body 1, both sides of the bottom end of the top plate 2203 are fixed with connecting plates 23, both sides of the top end of the support 2201 are fixed with guide columns 24, the top ends of the guide columns 24 penetrate the connecting plates 23 and are fixed with baffles 25, the top ends of the expansion plate 15 and the stabilizing plate 20 are fixed with a push plate 21.

When it is necessary to adjust the width of the support platform 2, the user only needs to pull the two expansion plates 15 in opposite directions, so that the opposite ends of the two expansion plates 15 match the elevator shaft, and then the plug pin 18 is inserted into the corresponding limiting hole 19, so that the position of the two expansion plates 15 can be limited. The two expansion plates 15 can fill the gap between the two ends of the support platform 2 and the inner walls of the elevator shaft, so as to expand the support platform 2, and the practicability is stronger. Through the setting of the second mounting plate 12, the third mounting plate 13 and the second bolt 14, the second ladder stand 9 can be limited, so that the first ladder stand 8 is prevented from lifting the second ladder stand 9 accidentally when the support platform 2 is lifted. When it is necessary to limit the stable plate 20, the user only needs to loosen the top plate 2203, the top plate 2203 moves towards the opposite under the reset thrust of the spring 2204, so as to drive the clamping column 2202 to move towards the opposite, the clamping column 2202 is inserted into the stable plate 20, and the stable plate 20 can be limited. Compared with the traditional multiple screws, this limiting method is more convenient and faster, and the practicability is stronger.
