The utility model relates to a kind of
ratchet drag
chain type rolling belt buckle, including
fixed frame and fixed mechanism, the fixed mechanism is arranged on
fixed frame, the fixed mechanism includes the steel band with multiple through holes being arranged on
fixed frame and rotatable setting on fixed frame pivot, the pivot is equipped with
ratchet and the clamping element of the through hole clamping, when needing to be fixed by steel band to bundle object, steel band is inserted into the gap between pivot and fixed frame, make the through hole on steel band with clamping ring accurate clamping, at this time, pull steel band, steel band drives clamping ring and pivot rotate together, pivot will simultaneously drive
ratchet rotate, ratchet positive rotation, push pawl moves and extrude
torsion spring, when steel band moves to certain distance after completing binding, pawl will be reset under the elasticity of
torsion spring, and clamped into the tooth slot of ratchet, prevent ratchet from rotating, ensure that steel band can stably fix bundle object.
