The present creation is focused on providing structural improvements to the locking device by pivotable installing a windlass in the interior body of the lock for winding the steel cable, also installed at one lateral side is a single-direction ratchet gear, with a rotary spring bent at another lateral side to drive the windlass, and a stopper of the locking mechanism controlled by the core of the locking device set at one lateral side of the windlass to cope with a compressed spring; a tenon and mortise are fixed onto the stopper corresponding to the single-direction ratchet gear, and at the end of the steel cable a ring is used to connect it with the locking pin on the steel cable or at the extreme end of the U-shape rod. When the locking pin is locked together with the body of the locking device, the safety helmet and other articles can then be locked firmly.

[What is claimed is:] [1.]a body having a hole;a locking core fixed within interior of said body;a steel cable having a first end fixedly connected with said body and a second end provided with a locking pin configured to engage with said locking core through said hole;a rectangular shell body integrally formed with said body;a windlass pivotally mounted in said rectangular shell body;a single-direction ratchet gear mounted on one side of said windlass;a rotary spring mounted on another side of said windlass to urge said windlass to rotate;a stopper urged by a spring to engage with said locking core and having a projection engaged with said ratchet gear;a winding cable having a first end fixedly connected with said windlass and a second end extending through said shell body to engage with a ring;whereby when in use, said ring is pulled out of said shell body to bind a desired article and engaged with said locking pin and then said locking pin is inserted in said hole to engage with said locking core, thus securely locking said article in place.
