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, configured to connect a first strap and a second strap, comprising: a controlling device forming a first through hole defining an axial line therethrough;an operating device connected to the first strap, the operating device forming a second through hole;a reel passing through the first and second through holes of the controlling and operating devices substantially along the axial line, the second strap wound around the reel, each of the first and second through holes being configured to maintain a displacement clearance about the reel;at least one ratchet set mounted on the reel, the reel being non-rotatable relative to the ratchet set; anda pawl device having a first pawl member and a second pawl member, the first pawl member disposed on the controlling device,wherein the controlling device is movable along a first radial direction relative to the reel between lock and unlock positions, in the lock position the first pawl member being engaged with the ratchet set, and in the unlock position the first pawl member being disengaged from the ratchet set,wherein the second pawl member is disposed on the operating device, the reel being movable along a second radial direction relative the operating device between a first position and a second position, in the first position the second pawl member being engaged with the ratchet set, and in the second position the second pawl member being disengaged from the ratchet set. 2. The ratchet buckle as claimed in claim 1, wherein a strain of the second strap pulls the reel toward the first position. 3. The ratchet buckle as claimed in claim 1, wherein the controlling device has two connectors, a handle and two extending portions; the handle is connected between the two connectors; there are two ratchet sets; there are two first through holes and two first pawl members; each first pawl member is defined on each corresponding connector; each first pawl member has a first engaging portion for preventing the ratchet set from being rotated; each extending portion is defined at one end of each corresponding connector; each extending portion presses each second pawl member and moves the reel relative to the first through hole; as a result, the second pawl member is prevented from being engaged with the ratchet set; the operating device has two wall members, a rod member, two first notches; the two wall members are spaced from each other; the rod member is connected between two ends of the two wall members; the rod member is connected to the first strap; each first notch is formed at a top periphery of each corresponding wall member; when the first pawl member is engaged with each corresponding first notch, the first pawl member is disengaged from the ratchet set. 4. A ratchet buckle, configured to connect a first strap and a second strap, comprising: a controlling device forming through hole defining an axial line therethrough;an operating device connected to the first strap;a reel passing through the through hole of the controlling device and the operating device substantially along the axial line, the second strap wound around the reel, the first through hole being configured to maintain a displacement clearance about the reel;at least one ratchet set mounted on the reel, the reel being non-rotatable relative to the ratchet set; anda pawl device having a first pawl member, the first pawl member disposed on the controlling device,wherein the controlling device is movable along a radial direction relative to the reel between lock and unlock positions, in the lock position the first pawl member being engaged with the ratchet set, and in the unlock position each first pawl member being disengaged from the ratchet set. 5. The ratchet buckle as claimed in claim 4, wherein the operating device has two wall members and a rod member; the two wall members are spaced from each other; the rod member is connected between two ends of the two wall members; the rod member is connected to the first strap; the operating device has a pawl plate and an elastic member; the pawl plate is movably assembled between the two wall members; the elastic member is assembled on the pawl plate and the wall members; a recovery force of the elastic member has the pawl plate engage with the ratchet set. 6. The ratchet buckle as claimed in claim 5, wherein the controlling device has two connectors, a handle and two extending portions; the handle is connected between the two connectors; there are two ratchet sets; there are two first through holes and two first pawl members; each first pawl member is defined on each corresponding connector; each first pawl member has a first engaging portion for preventing the ratchet set from being rotated; each extending portion is defined at one end of each corresponding connector; each extending portion presses the pawl plate and disengages the pawl plate from the ratchet set; the operating device has two first notches; each first notch is formed at a top periphery of each corresponding wall member; when the first pawl member is engaged with each corresponding first notch, the first pawl member is disengaged form the ratchet set. 7. A ratchet buckle, configured to connect a first strap and a second strap, comprising: a controlling device forming a first through hole defining an axial line therethrough;an operating device connected to the first strap, the operating device forming a second through hole;a reel passing through the first and second through holes of the controlling and the operating devices substantially along the axial line, the second strap wound around the reel, each of the first and second through holes being configured to maintain a displacement clearance about the reel;a pawl device having a second pawl member; andat least one ratchet set mounted on the reel, the reel being non-rotatable relative to the ratchet set,wherein the controlling device is movable along a radial direction relative to the reel between first and second positions, in the first position the second pawl member being engaged with the ratchet set, and in the second position the second pawl member being disengaged from the ratchet set. 8. The ratchet buckle as claimed in claim 7, wherein a strain of the second strap pulls the reel toward the first position. 9. The ratchet buckle as claimed in claim 7, wherein the operating device has two wall members and a rod member; the two wall members are spaced from each other; the rod member is connected between two ends of the two wall members; the rod member is connected to the first strap; there are two ratchet sets; there are two second through holes and two second pawl members; each second pawl member is defined on each corresponding wall member; each second pawl member has a second engaging portion for preventing the ratchet set from being rotated; the controlling device has two connectors and a handle; the two connectors are connected to the reel; the handle is connected between the two connectors; the controlling device has a plate unit and an elastic unit; the plate unit is movably assembled between the two connectors; the elastic unit is assembled between the plate unit and the connectors; a recovery force of the elastic unit has the plate unit engage with the ratchet set. 10. The ratchet buckle as claimed in claim 9, wherein the controlling device has two extending portions; each extending portion is defined at one end of each corresponding connector; each extending portion presses each second pawl member and moves the reel relative to the second through hole; as a result, the second pawl member is prevented from being engaged with the ratchet set.
