By providing the circular openings 4 and the railings 3, tourists can be effectively protected by the railings 3 to prevent them from mistakenly entering dangerous areas.

[0023] Two grooves 203 are provided on the upper surface of the dam 1, and the inner bottom wall of each connecting block 201 is fixedly connected with a connecting plate 214, and the front and back sides of each connecting plate 214 are fixedly connected with a force spring 213, and the ends of each group of force springs 213 that are away from each other are fixedly connected with a limiting block 212, and an extrusion block 211 is provided inside each connecting block 201, and the upper surface of each extrusion block 211 is fixedly connected with a transmission column 210, and the inner wall of each transmission column 210 is rotatably connected with a first rotating shaft 209, and the inner wall of each transmission column 210 is fixedly connected with a first bearing 6, and the inner ring of each first bearing 6 is fixedly connected to the outer surface of the first rotating shaft 209. By providing the first bearing 6, the first rotating shaft 209 can be fixed by the first bearing 6, thereby ensuring that the first rotating shaft 209 rotates more stably.

[0024] The outer surface of each first rotating shaft 209 is fixedly connected to a rotating block 205, the inner wall of each rotating block 205 is rotatably connected to the second rotating shaft 206, the inner wall of each rotating block 205 is fixedly connected to a second bearing 5, and the inner ring of each second bearing 5 is fixedly connected to the outer surface of the second rotating shaft 206. By providing the second bearing 5, the second rotating shaft 206 can be fixed by the second bearing 5 to ensure that the second rotating shaft 206 will not fall off due to shaking during rotation.

[0025] The inner wall of each connecting block 201 is fixedly connected with a rotating shaft 207, the outer surface of each rotating shaft 207 is fixedly connected with a rotating plate 208, the inner wall of each rotating plate 208 is fixedly connected with the outer surface of the second rotating shaft 206, the left side of each connecting block 201 is provided with a rectangular opening 202 and a limiting groove 215, the interior of each rectangular opening 202 is slidably connected with the outer surface of the rotating plate 208, the interior of each limiting groove 215 is slidably connected with a baffle 204, the left side of each baffle 204 is fixedly connected with a toggle block 216, the inner wall of each extrusion block 211 is fixedly connected with two groups of third bearings 8, the inner ring of each group of third bearings 8 is fixedly connected with the third rotating shaft 7, by providing the third bearing 8 and the third rotating shaft 7, the third rotating shaft 7 can be rotated inside the extrusion block 211 through the third bearing 8, thereby achieving a better auxiliary effect.

[0026] The upper surface of each toggle block 216 and the bottom surface of the toggle block 216 are in contact with the inner wall of the connecting block 201, and the outer surface of each third rotating shaft 7 is fixedly connected to a roller 9, and the outer surface of each roller 9 is in contact with the upper surface of the limit block 212. By providing the roller 9, the friction between the extrusion block 211 and the limit block 212 can be reduced by the roller 9, so that the limit block 212 can easily enter the limited position.

[0027] The working principle of the utility model is as follows: when in use, the connecting block 201 can be directly inserted into the groove 203 on the upper surface of the dam 1, and then the rotating plate 208 is pushed to move upward, and the rotating block 205 can be pushed downward by utilizing the rotational connection relationship between the rotating plate 208 and the rotating shaft 207. The rotating block 205 and the first rotating shaft 209 also have a rotational connection relationship, so that the transmission column 210 and the extrusion block 211 will be pushed downward, so that the extrusion block 211 can be used to move downward to push the two limit blocks 212 to extend to both sides, so that the connecting block 201 can be clamped inside the dam 1 through the limit blocks 212, thereby completing the positioning of the connecting block 201, and then pulling the toggle block 216 drives the baffle 204 fixed on one side of the toggle block 216 to move inside the limit groove 215. In the above application, the shape of the limit groove 215 is a structure with a large inner neck and a small neck. The structure is designed in such a way that the height of the toggle block 216 is the same as the size of the neck position of the limiting groove 215, and the baffle plate 204 is the same as the height of the larger space inside the limiting groove 215. Therefore, the baffle plate 204 will not be separated from the limiting groove 215 due to the push of the rotating plate 208. Therefore, the rotating plate 208 can be limited by the baffle plate 204. The baffle plate 204 can limit the rotating plate 208 when it is not subjected to external thrust. It can ensure that the rotating plate 208 can still press the extrusion block 211 downward to push the extrusion block 211 to both sides. When disassembling, the rotating plate 208 is returned to its original position, so that the extrusion block 211 can be pulled back to its original position through a series of force transmission, and the force spring 213 can pull the two limiting blocks 212 back to their original positions through tension, thereby achieving the purpose of disassembly, thereby effectively avoiding the need for tools when installing and disassembling the device, which will result in certain limitations.
