A first joint 3 is fixedly connected to the left side of the first sleeve 1 and the second sleeve 2. The first joint 3 can cover the second joint 4. A second joint 4 is fixedly connected to the right side of the first sleeve 1 and the second sleeve 2. Both the first joint 3 and the second joint 4 are semi-cylindrical tubes, and the number of each is two. Through holes are provided on the first joint 3 and the second joint 4. A fixing component ⑤ is arranged on the front surface of the first sleeve 1. The fixing component 5 includes a support piece 501, and the support piece 501 is fixedly connected to the front surface of the first sleeve 1. A first spring telescopic rod 502 is fixedly connected to the right side of the support piece 501. The first spring telescopic rod 502 will always maintain an extended state in the normal state. At this time, the plug post 503 will be inserted into the fixing sleeve 506. The right end of the first spring telescopic rod 502 is fixedly connected to the plug post 503. A chamfer is provided at the right end of the plug post 503 to facilitate insertion into the fixing sleeve 506. A fixing rod 504 is fixedly connected below the plug post 503. The fixing rod 504 is perpendicular to the plug post 503. A limiting rod 505 is fixedly connected above the plug post 503. The limiting rod 505 is welded above the plug post 503. The limiting rod 505 movably penetrates through the right side of the support piece 501. A through hole is provided on the support piece 501 for the limiting rod 505 to pass through. The fixing component 5 further includes a fixing sleeve 506. The fixing sleeve 506 is movably sleeved on the outer surface of the plug post 503. The fixing sleeve 506 is fixedly connected to the front surface of the second sleeve 2.

[0024] When the above-mentioned device is in specific use, first, the second sleeve 2 is sleeved on the lower surface of the sling of the suspension bridge, and then the first sleeve 1 is closed downward to cooperate with the second sleeve 2 to cover the sling. At this time, the two first joints 3 and the second joints 4 will also be closed with each other. When the first sleeve 1 is closed downward, the fixing rod 504 is pulled to the left to drive the plug post 503 to move to the left. At this time, the first spring telescopic rod 502 will be compressed. When the first sleeve 1 and the second sleeve 2 are completely closed, the position of the plug post 503 will be aligned with that of the fixed sleeve 506. At this time, the fixing rod 504 is released, and the first spring telescopic rod 502 will release the elastic force to push the plug post 503 to the right. At this time, the plug post 503 will be inserted into the fixed sleeve 506, thereby fixing the first sleeve 1 and the second sleeve 2 together to protect the sling of the suspension bridge. At this time, multiple groups of the first sleeve 1 and the second sleeve 2 can be arranged on the sling in the same way. By inserting the second joint 4 on the adjacent two groups of the first sleeve 1 and the second sleeve 2 into the first joint 3 of another group and setting screws, nuts or rivets for fixation, the protective cylinders formed by multiple groups of the first sleeve 1 and the second sleeve 2 are connected together, so as to play a role in facilitating the protection of the entire sling.

[0025] Embodiment 2

The limiting component 6 includes a notch 601, the size of the notch 601 is adapted to that of the fixing seat 603, the notch 601 is opened on the front surface of the second sleeve 2, a second spring telescopic rod 602 is fixedly connected to the front surface of the inner surface of the notch 601, the second spring telescopic rod 602 will always be in the extended state under normal conditions, a fixing seat 603 is fixedly connected to the front end of the second spring telescopic rod 602, an opening is arranged on the front surface of the fixing seat 603, inclined surfaces are arranged on the left and right sides of the fixing seat 603, the fixing rod 504 is arranged on the inner surface of the fixing seat 603, when the second spring telescopic rod 602 is in the extended state, the fixing rod 504 can be exactly arranged in the opening on the fixing seat 603, a disassembly component 7 is arranged on the right side of the fixing seat 603, the disassembly component 7 includes an insertion cylinder 701, the insertion cylinder 701 is fixedly connected to the front surface of the second sleeve 2, the insertion cylinder 701 is welded to the front surface of the second sleeve 2 through a connecting rod, a top rod 702 is inserted on the left side of the insertion cylinder 701, and the shape of the top rod 702 is L-shaped.

[0027] When the above device is in specific use, after the first spring telescopic rod 502 releases elastic force to push the plug post 503 to the right so that it is inserted into the fixed sleeve 506, the fixed rod 504 on the plug post 503 will abut against the inclined surface on the left side of the fixed seat 603. At this time, the plug post 503 is continuously pushed to the right to press the fixed seat 603 backward. At this time, the second spring telescopic rod 602 will be compressed. When the fixed rod 504 is located at the opening on the fixed seat 603, the second spring telescopic rod 602 will release elastic force to push the fixed seat 603 forward. At this time, the fixed seat 603 will cover the fixed rod 504, so that the plug post 503 is not easily detached from the fixed sleeve 506. When it is necessary to disassemble the first sleeve 1 and the second sleeve 2 on the sling, the ejector rod 702 is pulled out to the left from the insertion cylinder 701. The ejector rod 702 will first abut against the inclined surface on the right side of the fixed seat 603 and press it backward. Then, the ejector rod 702 will push the fixed rod 504 to drive the plug post 503 to be pulled out from the fixed sleeve 506 to cancel the fixation between the first sleeve 1 and the second sleeve 2, so as to facilitate the disassembly of the first sleeve 1 and the second sleeve 2 on the sling.
