Method of driving a sliding tool on ice-surface

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

• step a):
• placing a tool on an ice surface,
• making a user sit on a seat board with two feet off the ice surface and two hands holding the rotating rod of a hand-operated chain wheel;
• step b):
• counter-clockwise rotating and accelerating the hand-operated chain wheel by hands to drive the chain,
• rotating counterclockwise a chain wheel via the reversing action of a reversing gear to rotate counterclockwise a ratchet via a rotating shaft,
• rotating counterclockwise a disk under the limitation of limiters to the ratchet, and driving the transmission rods and the 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 the 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 the other 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 unscrewed between the disk and the annular disk, and
• rotating the friction members to generate force with the ice surface via the outermost ends of the unscrewed friction members through the counterclockwise rotation of the rotating shaft, wherein the rotation of the friction members provides power for the tool and the speed of a sliding tool gradually increases from 0 to accelerate the sliding when the linear speed of the friction members with the ice surface is greater than that of the sliding speed of the tool;
• step d):
• continue rotating counterclockwise the friction members with the disk and the annular disk by inertia and generating the force with the ice surface when the tool is needed to slide after the speed increases for a period of time,
• rotating clockwise the hand-operated chain wheel by hands 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 during the action with the ice surface is less than that of the sliding speed of the tool, and
• the chain wheel rotating clockwise the ratchet via the rotating shaft, wherein the limiters cannot restrict the ratchet to rotate clockwise, and 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 the other 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 that the friction members rotate around the rod shafts and the friction ends of the friction members be screwed between the disk and the annular disk, thereby releasing force between the rotating friction members and the ice surface, and eliminating the resistance for the sliding tool to prolong the sliding time;
• and
• step f):
• rotating counterclockwise the hand-operated chain wheel by hands when needs to decelerate the sliding tool in emergency to drive the chain and rotate counterclockwise the chain wheel through the reversing action of the reversing gear,
• the chain wheel rotating counterclockwise the ratchet 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 through the cylinder, the connecting plates and the annular disk,
• rotating counterclockwise the rotating shaft whose external threads of 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 other 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 unscrewed between the disk and the annular disk, thereby generating the force with the ice surface;
• wherein when the linear speed of the friction members during the action with the ice surface is less than the sliding 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 sliding tool.
