[0029] The rotation of the rotating block 307 drives the rotation of the bidirectional screw 302. At this time, the rotation of the bidirectional screw 302 drives the rotation of the rotating wheel 305. The rotating wheel 305 cooperates with the belt 306 to drive the two sets of bidirectional screws 302 to rotate synchronously.
