Direction is relevant with the object that drive gear engages, so, the direction of motion of swivel nut is relevant with the rotation direction of drive shaft, and drives
The rotation direction of axle is controlled by toggle mechanism；So said process just forms interactional cyclic motion process, stirs
Mechanism constantly influences continuous loop control with drive mechanism.
（12）Spacing between two shifting fork bars is more than the axial length of drive gear, can be carried to the motion of drive gear
Buffered for heterodromous inertia.
（13）Spacing between two shifting fork bars is more than the axial length of drive gear, and the length for being longer than drive gear is two
Shift fork distance between tie rods is relative to the length surplus of drive gear, and due to the presence of above-mentioned surplus, swing rod is when in vertical state, and two
Individual shifting fork bar will not be stopped by drive gear, only need to rely on inertia when swing rod crosses its vertical state.
（14）Travelling gear is coaxial with first gear, and second gear engages with travelling gear, realizes first gear and the
The reverse rotation of two gears.
（15）The first spring on first shut-down mechanism in time can reset the locking lever for producing displacement.
（16）Handle can pull up the locking lever on manual shut-down mechanism, the right-angle surface being so manually stopped in mechanism
The projection blocked can depart from constraint, and driving lever just can continue to move left and right, as long as can only be done the monocycle without pulling up mechanism
Motion.
（17）The position that manual shut-down mechanism is set projection can be blocked in drive gear be located exactly at first gear and
