[0026] The positioning assembly 8 includes a fixed block 81 fixedly connected to one side of the side plate 7, and a positioning rod 82 is slidably connected to the fixing block 81 inside the fixing block 81. A spring 83 is fixedly connected to the bottom end of the fixing block 81 on the outside of the positioning rod 82, and the bottom end of the positioning rod 82 is fixedly connected to a baffle 84 fixedly connected to the bottom end of the spring 83. The setting of the positioning assembly 8 can limit the sliding frame 5, thereby fixing the railing 3. The left and right ends of the bottom plate 9 are fixedly connected to the symmetrically arranged connecting plates 11, and the front and rear ends of the connecting plate 11 are symmetrically provided with grooves 12. The inner side of the groove 12 is rotatably connected to the connecting block 13, and a first circular hole 14 is provided inside the connecting block 13 to penetrate the connecting block 13 from left to right. The bottom end of the connecting block 13 is fixedly connected to the universal wheel 15, and a second circular hole 16 is symmetrically provided inside the connecting plate 11 to penetrate the connecting plate 11 from left to right and pass through the groove 12. A latch 17 is provided inside the first circular hole 14 and the second circular hole 16. The first circular hole 14, the second circular hole 16 and the latch 17 can cooperate to position the universal wheel 15, so that the movement of the device is more explosion-proof. The bottom end of the bottom plate 9 is fixedly connected to the water tank 18, the top of the water tank 18 is fixedly connected to the threaded pipe 19 that passes through the water tank 18, and the outer side of the threaded pipe 19 is spirally connected to the threaded cover 20. The front side of the water tank 18 is fixedly connected to the drain valve 21 that passes through the water tank 18. One side of the drain valve 21 is symmetrically arranged on the front and rear sides of the water tank 18 and fixed to the water tank 18. The mounting plate 22 is fixedly connected, and a vertically arranged long spike 23 is provided on the inner side of the mounting plate 22. The setting of the water tank 18 makes the center of gravity of the device closer to the ground and more stable.

The connection between the card block 4 and the card slot 10 is a snap connection. The positioning rod 82 passes through the top plate 1 and is slidably connected to the top plate 1. The positioning rod 82 is located on the inner side of the positioning hole 6, and the inner diameter of the first circular hole 14 is the same as that of the second circular hole 16.

[0027] When the railings 3 are adjusted, the spring 83 is pulled back to stretch the positioning rod 82, and the positioning rod 82 is pulled out of the positioning hole 6. The sliding frame 5 is pulled to slide on the outside of the top plate 1. When the sliding frame 5 is out of the top plate 1, the baffle 84 is released. Then, the distance between the railings 3 is adjusted as needed, and the railing 3 is inserted into the inner side of the through groove 2 until the block 4 is engaged with the slot 10 at the top of the bottom plate 9. After putting in several railings 3, the baffle 84 is pulled again, and the sliding frame 5 is placed on the outside of the top plate 1 to slide on the outside of the top plate 1 until the positioning rod 82 is vertically aligned with the positioning hole 6. The baffle 84 is released, and the spring 83 is reset to drive the positioning rod 82 to slide inside the fixed block 81 and the top plate 1 until the positioning rod 82 is inserted into the positioning hole 6. The adjustment of the distance between the railings 3 and the fixation of the railing 3 are completed. The setting of the positioning component 8 can limit the sliding frame 5, thereby fixing the railing 3. When the device needs to be moved, the device is directly pushed to rotate the universal wheel 15 at the bottom end of the connecting block 13, and the movement of the device can be completed. When the device needs to be fixed, the pin 17 is pulled out from the inside of the first circular hole 14 and the second circular hole 16, and the universal wheel 15 is rotated to make the connecting block 13 rotate inside the groove 12 on the connecting plate 11. At this time, the water tank 18 is in contact with the ground, and the threaded cover 20 is unscrewed from the outside of the threaded tube 19 and water is poured in, and the threaded cover 20 is screwed on, and finally the long nail 23 is inserted into the inside of the mounting plate 22 and hammered into the ground to complete the fixation of the device. When the use of the device is finished, the drain valve 21 can be opened to release the water in the water tank 18. The setting of the water tank 18 makes the center of gravity of the device closer to the ground more stable, and the setting of the mounting plate 22 and the long nail 23 makes the device more firmly fixed on a slope or uneven ground.
