[0027] Specifically, firstly, the outer shell 1 is placed inside one of the steel structures, and then the positioning plate 9 at the bottom of the outer shell 1 is inserted into the other steel structure, and then the telescopic rod 2 is pressed to drive the sliding block 4 and the limit block 5 to move. The movement of the sliding block 4 will apply pressure to the push plate 7, thereby causing the spring 8 to contract. At the same time, the movement of the sliding block 4 will drive the limit block 5 to slide on one side of the U-shaped limit groove 6, thereby moving to the corner of the U-shaped limit groove 6, and then sliding along the lateral side of the U-shaped limit groove 6, thereby driving the active wheel through the telescopic rod 2 10 rotates, and due to the meshing relationship between the driving wheel 10 and the driven wheel 11, the four driven wheels 11 rotate in response to the rotation of the driving wheel 10, and then through the meshing relationship between the driven wheel 11 and the rack 12, the rack 12 moves with the rotation of the driven wheel 11, thereby driving the block 13 to slide inside the positioning plate 9 and the steel structure to achieve the connection between the two steel structures, and then release the telescopic rod 2. At this time, the spring 8 is no longer stressed and rebounds, thereby driving the limit block 5 to move to the inside of the other side of the U-shaped limit groove 6 for limiting, thereby achieving the locking between the two steel structures.

[0028] Reference Figure 1 , Figure 5 and Figure 6 The upper surface of the positioning plate 9 is fixedly connected with an extension plate 14, the outer wall of the extension plate 14 is slidably connected to the inside of the outer shell 1, the upper surface of the outer shell 1 is fixedly connected with a fixing block 15, the inside of the fixing block 15 is rotatably connected with a rotating rod 16, the outer wall of the rotating rod 16 is fixedly connected with a worm 17, the inside of the fixing block 15 is rotatably connected with a worm wheel 18, the worm wheel 18 is meshed with the worm 17, the inside of the worm wheel 18 is fixedly connected with a screw 19, the outer wall of the screw 19 is rotatably connected to the inside of the outer shell 1, the outer wall of the screw 19 is threadedly connected to the inside of the extension plate 14, the top of the screw 19 is fixedly connected with a gear 20, the inner wall of the outer shell 1 is rotatably provided with a gear ring 21, and the gear 20 is meshed with the gear ring 21;

Due to the meshing relationship between the gear 20 and the gear ring 21, the gear ring 21 rotates with the rotation of the gear 20, thereby driving the other gears 20 to rotate synchronously, and then driving the four screws 19 to rotate. Then, through the threaded relationship between the screw 19 and the extension plate 14, the extension plate 14 slides inside the outer shell 1 with the rotation of the screw 19, thereby adjusting the distance between the outer shell 1 and the positioning plate 9, thereby achieving the effect of adjusting the length according to the thickness of the steel structure.

[0030] Working principle: When the locking assembly for directional connection of steel structure is needed, first place the outer shell 1 inside the steel structure, insert the positioning plate 9 into another steel structure, press the telescopic rod 2, the sliding block 4 and the limit block 5 move, the push plate 7 is compressed, the spring 8 contracts, the sliding block 4 moves to the corner of the U-shaped limit groove 6, slides along the lateral edge, drives the driving wheel 10 to rotate, thereby rotating the driven wheel 11, and then drives the rack 12 to move, and drives the card block 13 to slide into the steel structure through the rack 12, releases the telescopic rod 2, the spring 8 rebounds, the limit block 5 limits, and locks the steel structure;
