Embodiment
With reference to accompanying drawing, the utility model diameter of axle variable gears embodiment is described in further details.
Embodiment one
See Fig. 1, Fig. 2 and Fig. 3, described diameter of axle variable gears comprises gear 1, transparent cover 2 and some screws 3, the both ends of the surface of described gear 1 offer tapped hole 21, in gear 1, described tapped hole 21 is blind hole, described transparent cover 2 is provided with identical with gear quantity, the tapped hole 21 that pore size is identical, be located at transparent cover 2 upper screwed hole 21 for through hole, during normal use, transparent cover 2 is without the need to being arranged in gear 1, gear 1 is identical with ordinary gear, the axis hole that transparent cover 2 makes gear have to be different from gear axis hole 11 size is installed in the both ends of the surface of gear 1 when needing the gear of less axis hole, now axis hole becomes transparent cover axis hole 23, can be assemblied in on the axle of transparent cover axis hole 23 size, transparent cover 2 is provided with keyway and is convenient to transmitting torque.
