[0031] Specifically, the handle 8 is pulled to drive the slide bar 4 to slide, and the slide bar 4 drives the first slide block 5 to slide in the first slide groove 11, and the armrest frame 7 drives the second slide block 9 in the second slide groove 12, so that the slide bar 4 can slide to the required position as needed, and the rotating block 20 is rotated to make the rotating block 20 drive the fixed rod 21 and the second slot 22 to engage, thereby achieving the effect of adjusting the position of the armrest frame 7 and the handle 8.

[0032] A clamping block 14 is slidably connected inside the slide rod 4 , and a second limiting plate 15 is fixedly connected to the outer wall of the clamping block 14 .

[0033] Specifically, by arranging the second limiting plate 15 on the outer wall of the clamping block 14 , the clamping block 14 will not be separated from the slide bar 4 when the clamping block 14 is pressed, thereby achieving the effect of preventing the clamping block 14 from falling off.

[0034] One end of a spring 16 is fixedly connected to the outer wall of the second limiting plate 15 , and the other end of the spring 16 is fixedly connected to the inside of the sliding rod 4 .

[0035] Specifically, by arranging a spring 16 on the outer wall of the second limiting plate 15 , the clamping block 14 can automatically reset under the action of the spring 16 after being pressed, thereby achieving the effect of opening and closing with the first clamping slot 18 .

[0036] A second slot 17 is formed inside the sliding rod 4 , and an outer wall of the second limiting plate 15 is slidably connected to an inner wall of the second slot 17 .

[0037] Specifically, by opening the second slot 17 inside the slide rod 4 , the second limiting plate 15 and the spring 16 can be placed in the second slot 17 , thereby achieving the effect of accommodating the card block 14 when the card block 14 is pressed.

[0043] Specifically, by providing the second slide groove 12 inside the box body 1 , the second sliding block 9 can slide in the second slide groove 12 , thereby achieving the effect of facilitating the sliding of the handrail frame 7 and providing vertical support for the handrail frame 7 .

[0044] A third sliding groove 13 is provided inside the sleeve 2 , and the outer wall of the connecting block 6 is slidably connected to the inner wall of the third sliding groove 13 .

[0045] Specifically, by opening the third sliding groove 13 inside the sleeve 2, the connecting block 6 can slide in the third sliding groove 13, thereby preventing the handrail frame 7 and the sleeve 2 from getting stuck when the slide rod 4 is pulled.

[0046] Working principle: When a telescopic handrail structure for a construction elevator is needed, first press the block 14 to disengage the block 14 from the first slot 18. At this time, pull the handle 8, and the handle 8 drives the slide bar 4 to slide through the handrail frame 7 and the connecting block 6. The slide bar 4 drives the first slide block 5 to slide in the first slot 11, and the handrail frame 7 drives the second slide block 9 to slide in the second slot 12. After the slide bar 4 slides to the required position, the block 14 pops out from the first slot 18 under the action of the spring 16 to engage, preventing the slide bar 4 from continuing to slide, and rotating the rotating block 20. The rotating block 20 drives the fixed rod 21 to rotate under the action of the rotating shaft 19, so that the fixed rod 21 and the second slot 22 are engaged, the first limit plate 3 can prevent the sliding rod 4 from detaching from the sleeve 2, the second limit plate 15 can prevent the block 14 from detaching from the sliding rod 4, the third sliding groove 13 opened inside the sleeve 2 can allow the connecting block 6 to slide therein, the first slot 10 opened inside the sleeve 2 can accommodate the sliding rod 4, the second slot 17 opened inside the sliding rod 4 is convenient for placing the spring 16 and the second limit plate 15 and can accommodate the block 14 when the block 14 is pressed.
