The inner wall array of the push rod 34 is distributed with sliding chutes 33, and the inner wall array of the cylinder 31 is provided with guide blocks 32 which extend into the sliding chutes 33 and are connected with the sliding chutes in a sliding manner. And a limiting ring 9 positioned below the sliding plate 10 is fixedly arranged on the inner wall of the fourth cavity 8. A reset diamond block 46 is fixedly installed on the outer side of the third rotating shaft 47, and a reset mandril 48 penetrating through the bottom of the first cavity 20 is fixedly installed at the bottom of the lifting plate 17. The box body 1 is made of metal.

Referring to the attached figures 1 to 8: a use method of an adjustable self-adaptive wrist strength training device comprises the following steps:

firstly, general training: liquid is filled in the fourth cavity 8 and the fifth cavity 54, when wrist strength training is needed, the first rotating shaft 21 is twisted by hands to rotate, the first rotating shaft 21 rotates to drive the convex rod 15 to rotate and the lantern ring 19 to rotate, the convex rod 15 rotates to drive the clip frame 16 to lift, the clip frame 16 lifts to drive the first lifting rod 11 to lift, the first lifting rod 11 drives the sliding plate 10 to lift, when the sliding plate 10 lifts, liquid in the fifth cavity 54 is sucked into the fourth cavity 8 through the first pipe body 6, when the sliding plate 10 descends under the action of the fourth spring 12, the liquid is discharged back into the fifth cavity 54 from the second pipe body 5 and the third pipe body 3, when the speed of twisting the first rotating shaft 21 is appropriate, the generated centrifugal force is small, so that the push rod 34 in the pipe body 31 cannot be thrown out under the action of the first spring 30 when the lantern ring 19 rotates, and then the second fixing plate 22 is pushed;

II, over-exercise protection: when the speed of twisting the first rotating shaft 21 is too fast, the centrifugal force generated is large, so that the push rod 34 slides out of the cylinder 31 to push the second fixing plate 22 to descend, the second fixing plate 22 descends to drive the second lifting rod 50 to descend, the second lifting rod 50 descends to push the first fixing plate 51 to descend, the first fixing plate 51 descends to push the first rack 43 to descend, the first rack 43 descends to drive the first gear 44 to rotate, the first gear 44 rotates to drive the second pawl sleeve 35 to rotate, the second pawl sleeve 35 rotates to drive the second rotating shaft 37 to rotate, the second rotating shaft 37 rotates to drive the toothless gear 39 and the third rotating shaft 47 to rotate, the toothless gear 39 rotates to drive the second rack 52 to descend, the second rack 52 descends to drive the third fixing plate 40 to descend, the third fixing plate 40 descends to drive the third lifting rod 41 to descend, the third lifting rod 41 descends to drive the fourth fixing plate 26 to descend, the fourth fixing plate 26 descends to drive the third rack 29 to descend, third rack 29 descends and drives second gear 27 rotatory, second gear 27 is rotatory to drive fourth pivot 28 rotatory, fourth pivot 28 is rotatory to drive ball valve 2 rotatory, the flow in the third body 3 is reduced in the ball valve 2 rotation makes, lead to sliding plate 10 descending speed to slow down this moment, force people to slow down training speed, third pivot 47 drives the rhombus 46 that resets to rotate during the rotation, it is rotatory to drive the rhombus 46 that resets when the ejector pin 48 that resets descends, it is rotatory that the rhombus 46 that resets drives third pivot 47, third pivot 47 is rotatory to drive second pivot 37 rotatory, second pivot 37 is rotatory to make scarce tooth gear 39 rotatory to breach department, second rack 52 receives the effect of third spring 42 and rises when scarce tooth gear 39 rotates to breach department and resets, ball valve 2 resumes initial position this moment.

While the invention has been shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the appended claims.
