The drag chain mechanism comprises an A swing drag chain, a first drag chain support and a second drag chain support, the first drag chain support is fixed to the front side of a ram, the second drag chain support is fixed to the left side of a fork-shaped body, the upper end of the A swing drag chain is fixed to the lower end of the first drag chain support, and the lower end of the A swing drag chain is fixed to the upper end of the second drag chain support. A vertical supporting plate is fixed to the right side of the fork-shaped body and located below the A swing drag chain, and the A swing drag chain is supported by the supporting plate. According to the drag chain mechanism, the supporting plate is arranged below the A pendulum drag chain, the weight of the whole A pendulum drag chain and the weight of cables and pipelines in the A pendulum drag chain are distributed on the supporting plate, and the stress between chain links of the drag chain is greatly reduced. According to the drag chain mechanism,
