3. A wide range of damping adjustable wrist exerciser according to claim 1, wherein: the pipe wall of the adjusting pipe is provided with a plurality of through holes which are densely distributed.
4. A wide range of damping adjustable wrist exerciser according to claim 3, wherein: the adjusting pipe is characterized in that a filter screen is arranged on the outer side of the adjusting pipe, and the outer pipe wall of the adjusting pipe is completely wrapped by the filter screen.
5. The wide range damping adjustable wrist exerciser of claim 4, wherein: the filter screen is made of metal materials.
6. A wide range of damping adjustable wrist exerciser according to claim 1, wherein: the stirring mechanism consists of a plurality of baffles.
7. The wide range damping adjustable wrist exerciser of claim 6, wherein: the baffles are circumferentially arrayed around the axis of the second holding part, and can radially extend and retract along the second holding part.
8. The wide range damping adjustable wrist exerciser of claim 6, wherein: and a convex block is arranged on the outer wall of the second holding part and is connected with the second holding part through a spring.
9. The method of using a wide-range damping adjustable wrist exerciser according to any one of claims 1-8, comprising the steps of:
the baffle is completely retracted into the second holding part, the protruding block is kept in a bouncing state, the baffle gradually extends out of the second holding part, the contact area of the baffle and non-Newtonian liquid is gradually increased until the wrist strength exerciser is adjusted to appropriate rotation damping, and wrist strength exercise can be started.
10. The method of using a wide range of damping adjustment wrist exerciser according to claim 9, wherein the method further extends the damping range of the wrist exerciser based on the fact that the baffle has extended to the maximum contact area with non-newtonian fluid, comprising the steps of:
A. moving the telescopic end of the second holding part towards the end of the first holding part without the through hole, extruding and injecting pure water in the adjusting pipe into the non-Newtonian liquid, reducing the concentration of the non-Newtonian liquid, and reducing the rotational damping of the wrist force exerciser;
B. move the flexible end of second portion of gripping towards first portion of gripping through hole one end, form the vacuum in the adjusting tube, non-Newtonian liquid is blockked by the filter screen, and liquid water is intraductal by the suction adjusting, and non-Newtonian liquid concentration improves, and wrist power exerciser rotates the damping increase.
