Be provided with trapezoidal thread on the cylinder barrel wall of described oil cylinder, be provided with the screw thread that is meshed with trapezoidal thread on the inwall of turbine.
The two ends of described turbine suit is provided with two thrust ball bearings, and two thrust ball bearings and turbine are arranged on box house by cover plate.
Be provided with two bearings between described worm screw and the casing, two bearings are set with the two ends that are arranged on worm screw.
Syndeton between described worm screw and the dwang is: dwang penetrates the inside that is arranged on worm screw, and fixes by key and worm screw.
The invention has the beneficial effects as follows: the blowning installation of above-mentioned bottle blowing machine, adopt turbine and worm screw directly to adjust the upper-lower position of cylinder tube, thereby reach the purpose of adjusting the blow needle upper-lower position.Compare with the blowning installation of present employed blowing cylinder, its adjust precision higher, regulate the speed comparatively fast, and device structure is simple, easy for installation.
