Method of driving a sliding tool on ice-surface

A method of driving a sliding tool on ice-surface, the method comprising:

• step a):
• placing a tool on an ice surface, and
• making a user sit on a seat board with hands holding a rotating rod of a hand-operated chain wheel;
• step b):
• rotating counterclockwise and accelerating the hand-operated chain wheel to drive a chain,
• rotating counterclockwise a chain wheel via a reversing action of a reversing gear to rotate counterclockwise a ratchet via a rotating shaft,
• rotating counterclockwise a disk under limitation of limiters to the ratchet, and
• driving transmission rods and friction members to rotate counterclockwise via a cylinder, connecting plates, and an annular disk;
• step c):
• abutting internal threads of a through chamber in a tapered base against external threads on the rotating shaft which has not yet rotated through a tension of a return spring in order to restrict the tapered base to move toward an H-shaped connecting frame, wherein the external threads of the rotating shaft match with the internal threads of the through chamber when the rotating shaft is rotated counterclockwise,
• moving the tapered base toward the H-shaped connecting frame along limiting rods until the internal threads of the through chamber arrive at an outer side of the external threads of the rotating shaft and abut against each other under the return spring,
• approaching trapezoidal limiting blocks to the rotating shaft under the disk and first pressure springs when the tapered base moves toward the H-shaped connecting frame,
• making the friction members rotate around rod shafts and friction ends of the friction members be deployed between the disk and the annular disk, and
• rotating the friction members to generate force with an ice surface via outermost ends of the deployed friction members through the counterclockwise rotation of the rotating shaft, wherein the rotation of the friction members provides power for the tool, and
• a speed of the tool gradually increases from 0 to accelerate the sliding tool when a linear speed of the friction members with respect to the ice surface is greater than the speed of the tool;
• step d):
• continuing rotating counterclockwise the friction members with the disk and the annular disk by inertia and generating the force with the ice surface to slide the tool after the speed increases for a period of time,
• rotating clockwise the hand-operated chain wheel to drive the chain and rotate clockwise the chain wheel through the reversing action of the reversing gear when the rotation of the friction members stops to provide power for the tool but provide resistance instead and the linear speed of the friction members with respect to the ice surface is less than the speed of the tool, and
• allowing the chain wheel to rotate the ratchet clockwise via the rotating shaft, wherein the ratchet is unable to restrict the limiters to rotate clockwise, whereby the disk and the friction members continue to rotate counterclockwise by inertia;
• step e):
• rotating clockwise the rotating shaft whose external threads are matched with the internal threads of the through chamber when the internal threads of the through chamber in the tapered base abut against the external threads on the rotating shaft via the pressure of the return spring,
• moving the tapered base away from the H-shaped connecting frame along the limiting rods until the internal threads of the through chamber arrive at an inner side of the external threads of the rotating shaft and abut against each other under the return spring, moving the trapezoidal limiting blocks away from the rotating shaft under the disk and the first pressure springs when the tapered base moves away from the H-shaped connecting frame, and
• making the friction members rotate around the rod shafts and the friction ends of the friction members be retracted between the disk and the annular disk, thereby releasing the force between the rotating friction members and the ice surface, and eliminating the resistance for the tool to prolong sliding;
• and
• step f):
• rotating counterclockwise the hand-operated chain wheel to decelerate the tool in emergency to drive the chain and rotate counterclockwise the chain wheel through the reversing action of the reversing gear,
• allowing the chain wheel to rotate the ratchet counterclockwise via the rotating shaft,
• rotating counterclockwise the disk under the limitation of the limiters to the ratchet,
• rotating counterclockwise the transmission rods and the friction members via the cylinder, the connecting plates, and the annular disk,
• rotating counterclockwise the rotating shaft, the external threads of which are matched with the internal threads of the through chamber,
• moving the tapered base toward the H-shaped connecting frame along the limiting rods until the internal threads of the through chamber arrive at the outer side of the external threads of the rotating shaft as well as the internal threads of the through chamber and the external threads of the rotating shaft abut against each other under the action of the return spring,
• approaching the trapezoidal limiting blocks to the rotating shaft under the action of the disk and the first pressure springs when the tapered base moves toward the H-shaped connecting frame, and
• making the friction members rotate around the rod shafts and the friction ends of the friction members be deployed between the disk and the annular disk, thereby generating the force with the ice surface;
• wherein when the linear speed of the friction members with respect to the ice surface is less than the speed of the tool by rotating the hand-operated chain wheel, and the rotation of the friction members stops to provide power for the tool but provide resistance instead to decelerate the tool.
