Novel linear steering engine anti-torsion mechanism

The utility model relates to the technical field of linear steering engines, in particular to a novel torsion preventing mechanism of a linear steering engine, which comprises a box body, the box body comprises a gear box, the bottom end of the gear box is fixedly connected with a box cover, the inner side of the gear box is provided with a bearing mounting seat, and the top end of the bearing mounting seat is fixedly connected with a shell. The first gear is driven by the motor and the controller assembly to rotate, the ball screw can rotate under the action of the second gear and the third gear, and then the screw nut conducts vertical linear motion under the action of cooperation of the anti-rotation sleeve shaft, the deep groove ball bearing and the sliding rail and drives the telescopic shaft to move along with the screw nut. The outer ring of the deep groove ball bearing rolls up and down on the sliding rail along with the lead screw nut, a traditional linear steering engine sliding block sliding mode c
