Method for achieving screw propulsion of cylindrical rod body

The invention discloses a method for achieving screw propulsion of a cylindrical rod body. The method includes the steps that the required cylindrical rod body is selected; a supporting frame with thetop being provided with a V-shaped groove is further selected; the included angle formed between the left wall surface and the right wall surface of the V-shaped groove is alpha, and the intersectingline between the left wall surface and the right wall surface of the V-shaped groove is called an inside corner line; a horizontal movement device is installed on the left wall surface and the rightwall surface of the V-shaped groove, a plurality of left horizontal movement units of the horizontal movement device are correspondingly installed on the left wall surface and further comprise turningwheel brackets and turning wheels, the included angle between a left intersecting line of the turning wheel cross section of the left wall surface and the left wall surface and the inside corner lineis beta1 and smaller than 90
