Air blowing screw machine

The utility model discloses a blowing screw machine, relates to the technical field of screw machines, and aims to solve the problems that in the prior art, although the frictional resistance of a screw locking mechanism during operation is effectively reduced, the machine performance is stable, and the screw locking quality is ensured, the clamping is unstable due to external factors of a motor during operation. And screw installation is influenced. The supporting plates are arranged on the upper surface of the operation table, the number of the supporting plates is two, and second sliding grooves are formed in the supporting plates; the second sliding plates are arranged on the second sliding grooves, the second sliding plates are connected with the second sliding grooves in a sliding mode, a first air cylinder is arranged at the rear end of the locking mechanism, a first hydraulic telescopic rod is arranged at the top of the front end face of the locking mechanism, and a third sliding groove is formed in t
