Abstract
A chain assembling-disassembling structure includes an assembling base, a first clamping component, a second clamping component, a penetrating shaft and a driving shaft. The assembling base has a fixing portion and the fixing portion has a concave edge for receiving a bushing of the chain section. And, the assembling base includes a first portion and a second portion vertically formed at two opposite ends thereof for respectively engaging with the first and second clamping components. Here, the first and second clamping components together clamp and restrict the chain. The second clamping component has a tubular shape for being inserted by the penetrating shaft, and then, the driving shaft can further be locked into the second clamping component. By turning the driving shaft, the penetrating shaft can be forced to push out a pin, which is used for jointing the inner and outer link plates of the chain.
