Continuous turn -buckle

The utility model discloses a continuous turn -buckle has solved the problem that current turn -buckle can not continuous operation. Specifically include action wheel, initiative wheel carrier, follow driving wheel, driven wheel carrier, ratchet, pawl, ratchet spanner and couple, initiative wheel carrier and driven wheel carrier to insert and fixed after form square frame, action wheel and setting up respectively along the recess of its circumference from the wheel surface of driving wheel, the two is fixed respectively on initiative and driven frame, and the recess of the two has formed the wire and wears double -layered hole, the ratchet is fixed in the second punching epaxially, and ratchet spanner, ratchet and pawl constitute unidirectional rotation mechanism, the turn -buckle utilizes two to take the notched runner to press from both sides tight wire, and the combined action of unidirectional rotation mechanism drives action wheel unidirectional rotation to rely on the friction between runner surface and
