The present invention discloses a quick tightener, which addresses the problems existing in the conventional tighteners such as inconvenient operation or failure in use under extreme conditions. The quick tightener includes a support, a handle, a ratchet wheel and a half-moon shaft. The half-moon shaft is composed of a first half-moon shaft and a second half moon shaft. Said first half-moon shaft could be fixedly connected with the ratchet wheel. Said second half-moon shaft could be fixedly connected with the ratchet wheel in the circumferential direction and axially move relative to the ratchet wheel. A clutch device is located between said first half-moon shaft and second half-moon shaft to connect the second half-moon shaft to the first half-moon shaft or disengage the second half-moon shaft from the first half-moon shaft. Such a quick tightener is equipped with the advantages such as preferential reliability and a high practical value.
A quick tightener, comprising a support (1), a handle (4), a ratchet wheel (3) and a half-moon shaft (2), the handle (4) could be hinged to the support (1) via the half-moon shaft (2), the ratchet wheel (2) could be connected with the half-moon shaft (2) and the handle (4) could drive the ratchet wheel (3) to rotate, the half-moon shaft (2) is composed of a first half-moon shaft (2b) and a second half moon shaft (2a), in which both the first half-moon shaft (2b) and the second half-moon shaft (2a) could be connected with the ratchet wheel (3) of the tightener and a spacing could be provided there between to connect the binding belt, characterized in that, said first half-moon shaft (2b) could be fixedly connected with the ratchet wheel (3), said second half-moon shaft (2a) could be fixedly connected with the ratchet wheel in the circumferential direction, said second half-moon shaft (2a) could axially move relative to the ratchet wheel (3), and a clutch device is located between said first half-moon shaft (2b) and second half-moon shaft (2a) to connect the second half-moon shaft (2a) to the first half-moon shaft (2b) or disengage the second half-moon shaft (2a) from the first half-moon shaft (2b).
