Good effect of the present invention

1, the alternate reciprocating motion by two cylinders realizes guide rail continuous linear and moves, and the length of guide rail is restriction not.

2, by inclined to one side axle, realize one-way rolling and guide rail clutch direction adjusting facility.

3, simple in structure, compact stable drive.
