A ratchet buckle, which is configured to connect a first strap and a second strap, includes a controlling device, an operating device connected to the first strap, a reel passing through the controlling device and the operating device along an axial line, the second strap wound around the reel, at least one ratchet set mounted on the reel, the reel being not rotated relative to the ratchet set, and a pawl device. When the user wants to unwind the second strap from the reel, the user moves and rotates the controlling device smoothly with only one hand thereof; therefore, it's very convenient for the user to operate. |

1. A ratchet buckle, which is configured to connect a first strap and a second strap, comprising:
a controlling device; an operating device connected to the first strap; a reel passing through the controlling device and the operating device along an axial line, the second strap wound around the reel; at least one ratchet set mounted on the reel, the reel being not rotated relative to the ratchet set; and a pawl device having a first through hole, a first pawl member, a second through holes and a second pawl members, the first through hole formed on the controlling device therethrough, along the axial line, the reel passing through the through holes, the first pawl member defined on the controlling device, the first pawl member being close to the first through hole, the first through hole being movable relative to the reel so that the controlling device and the first pawl member are movable between a lock position under which the first pawl member is engaged with the ratchet set, and an unlock position under which the first pawl member is disengaged from the ratchet set, the second through hole formed on the operating device therethrough, along the axial line, the reel passing through the second through hole, the second pawl member defined on the operating device, the second pawl member being close to the second through hole, the reel being movable relative the second through hole so that the reel is movable between a first position under which the second pawl member is engaged with the ratchet set, and a second position under which the second pawl member is disengaged from the ratchet set. |
