[0002] Chains are generally metal links or rings, mostly used for mechanical transmission and traction, chain-shaped objects used to block traffic channels, chains for mechanical transmission, chains include four major series: transmission chains, conveyor chains, traction chains and special professional chains, a series of often metal links or rings: chain-shaped objects used to block traffic channels, chains for mechanical transmission, chains can be divided into short pitch precision roller chains, short pitch precision roller chains, bent plate roller chains for heavy-duty transmission, chains for cement machinery, plate chains, high-strength chains. In the process of modern shipbuilding, after the hull is transported, turned over and hoisted in sections, before the subsequent work on the slipway or in the sand room in sections, for safety reasons, the safety protection chain must be pulled and installed first. The chain is supported by a safety rod about 2 meters apart, and two clasps are fixedly installed on the safety rod. The chain is pulled through the clasps on the safety rod, so the safety rod is installed and fixed first, and then the chain is pulled.

[0003] Since the chain is at least 30 meters long and the chain cannot be locked after passing through the clasp, it is inevitable that there will be looseness, which cannot achieve the purpose of safety protection and will also leave safety hazards. Therefore, it is necessary to tighten the chain and then fasten the chain to the clasp with a small shackle, which has low work efficiency. In addition, small shackles need to be purchased separately every year. Small shackles are prone to rust during long-term use, making it difficult to loosen some small shackles after rusting, resulting in a high replacement rate and increased production costs.
