The utility model discloses a crank shaft used in a connecting rod beating-up mechanism of an air-jet loom. The crank shaft comprises a rotating shaft and a crank part which is hinged with a connecting rod, wherein a guide rail is fixedly arranged on the rotating shaft along the radial direction of the rotating shaft; the end part of the rotating shaft arranged on the crank part can slide along the guide rail; the crank shaft further comprises a locking device used for locking one end part of the crank part on the guide rail; and the locking device comprises a sliding screw mechanism fixedly connected with the end part of the crank part. In the crank shaft provided by the utility model, the crank part can slide along the radial direction of the rotating shaft, so that the length of the crank shaft can be adjusted freely, and the length of the crank shaft can be well fixed.
