When the abutment block 5 moves, the alarm trigger button 8 will be triggered, so that the alarm 9 will sound, which can remind the construction personnel in time; by providing the card block 4 and the card slot 3, and providing the abutment block 5 connected to the telescopic rod 2, when the scaffold is offset, the movement of the telescopic rod 2 can drive the card block 4 to be stuck in the card slot 3, preventing the telescopic rod 2 from continuing to move outward, and can fix the scaffold, giving the construction personnel enough time to escape. In addition, by providing the alarm trigger button 8 and the alarm 9, when the scaffold is offset, the alarm 9 can be used to remind the construction personnel, so that the construction personnel can escape in time.
[0024] like Figure 3As shown, the two ends of the main rod 1 are coaxially symmetrically provided with a contraction cavity 10, and the telescopic rod 2 is slidably installed in the contraction cavity 10; the outer side of the contraction cavity 10 is provided with a block cavity 11 connected to the contraction cavity 10, and the block 4 is hinged in the block cavity 11 through a torsion spring shaft 12; the outer side of the block cavity 11 is provided with a slide plate cavity 13 connected to the block cavity 11, and a slide plate 14 is slidably installed inside the slide plate cavity 13, and a top block 5 is fixedly installed on the inner side of the slide plate 14, and the top block 5 abuts against the block 4; a take-up cavity 15 is provided inside the telescopic rod 2, and the take-up wheel 7 is installed in the take-up cavity 15 through a torsion spring rod 16, and a rope hole 17 is provided on the inner side of the take-up cavity 15, and a rope hole 17 is also provided inside the main rod 1, and one end of the rope hole 17 in the main rod 1 is connected to the rope hole 17 in the telescopic rod 2, and the other end of the rope hole 17 in the main rod 1 is connected to the slide The board cavities 13 are connected, one end of the pull rope 6 is connected to the take-up wheel 7, and the other end of the pull rope 6 passes through the pull rope hole 17 and is connected to one end of the slide plate 14.

When the steel pipe of the scaffolding is tilted, the telescopic rod 2 moves outward, and the slide plate 14 is pulled by the pull rope 6 to move, and then the slide plate 14 brings the push block 5 to press the card block 4, so that the card block 4 is stuck in the card slot 3 to fix the telescopic rod 2. When resetting is required, the telescopic rod 2 is pushed inward; when passing, the pull rope 6 bypasses the roller 18, which can reduce the wear of the pull rope 6.
[0025] like Figure 2 As shown, a transfer rod 20 is rotatably installed near the middle of the main rod 1, and internal tooth holes 21 are coaxially provided at both ends of the transfer rod 20. An abutting gear rod 22 is installed on the internal thread of the internal tooth hole 21. The outer end of the abutting gear rod 22 extends into the contraction cavity 10 to abut the telescopic rod 2, and a limiting groove 23 is provided on the outer surface of the abutting gear rod 22. A limiting slide groove 23 is fixedly installed inside the main rod 1, and the limiting slide groove 24 is located in the limiting slide groove 23; when the transfer rod 20 is rotated, the abutting gear rod 22 can be moved outward or inward through threaded movement, and then can move outward or inward against the telescopic rod 2, thereby achieving the effect of adjusting the overall length of the device, wherein the limiting groove 23 and the limiting slide groove 24 can prevent the abutting gear rod 22 from rotating with the transfer rod 20.
[0026] like Figure 2As shown, a limiting ring 25 is coaxially fixedly installed on the outer surface of the transfer rod 20 near the two ends, and a matching groove for matching the limiting ring 25 is opened inside the main rod 1; an inner gear ring 26 is coaxially fixedly installed on the outer surface of the transfer rod 20 near the middle, a gear hole 27 is opened inside the main rod 1, and an intermediate gear 28 is rotatably installed inside the gear hole 27, and the intermediate gear 28 is meshingly connected with the inner gear ring 26; a torsion ring 29 is coaxially rotatably installed on the outer surface of the main rod 1 near the middle, and the inner surface of the torsion ring 29 is meshingly connected with the intermediate gear 28; by rotating the torsion ring 29, the transfer rod 20 can be rotated through the intermediate gear 28 and the inner gear ring 26.
[0027] like Figure 2 and Figure 4 As shown, an electromagnet 30 is fixedly installed at one end of the telescopic rod 2 away from the abutting gear rod 22, a spring hole 31 is opened on the side of the electromagnet 30 close to the abutting gear rod 22, a spring 32 is arranged inside the spring hole 31, and the two ends of the spring 32 are respectively connected to the electromagnet 30 and the abutting gear rod 22; an iron block 34 is installed on the side of the electromagnet 30 through a locking spring 33, and the iron block 34 extends into the inside of the pull rope hole 17 and abuts against the pull rope 6; a battery 35 is arranged inside the main rod 1, and a button 36 is embedded on the outer surface of the main rod 1, and the button 36 is electrically connected to the battery 35 The battery 35 is electrically connected to the electromagnet 30; in the normal state, the iron block 34 presses against the draw rope 6 and is tightly attached to the side wall of the draw rope hole 17, thereby fixing the draw rope 6. When the telescopic rod 2 needs to be moved outward to adjust the length of the device, the button 36 is pressed to energize the electromagnet 30, so that the iron block 34 overcomes the elastic force of the locking spring 33 and decreases, thereby losing the fixation of the draw rope 6. When the torsion ring 29 is turned and the telescopic rod 2 moves outward, the draw rope 6 will pull the take-up wheel 7 and the torsion spring rod 16 to rotate, making the draw rope 6 longer, thereby preventing the draw rope from pulling the slide plate 14 and causing a false alarm.
[0028] like Figure 1-2 As shown, a universal joint 37 is fixedly installed at one end of the telescopic rod 2 outside the main rod 1, and a clamping claw is fixedly installed on the universal joint 37; by setting the universal joint 37, the device can be connected to scaffolds erected in various ways, wherein the clamping claw can be replaced according to actual needs.
