The present invention relates to the technical field of windlasses, and discloses an anchoring structure, a windlass based on this structure and a usage method. Through the setting of the connection component, when it is necessary for the windlass to simultaneously retrieve the ship anchor and the cable, the crew uses the lever to push the engagement shaft to dock with the engagement disc of the winch, becoming an integral whole. So that when the windlass drives the winch to rotate and retrieve the anchor chain, it can also synchronously drive the auxiliary drum to rotate, enabling the auxiliary drum to retrieve the cable. When it is necessary for the windlass to separately retrieve the ship anchor or the cable, the crew uses the lever to push the connecting shaft to separate from the engagement disc of the winch, making the winch and the auxiliary drum independent of each other, and capable of separately retrieving the ship anchor or the cable. Thus, the windlass can be applied to various situations, improving the applicability of the device.
