Abstract

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.
