[0037] In one embodiment, Figure 1As shown, a plurality of telescopic rods 30 are disposed between the first rotating ring 22 and the second rotating ring 23 , so that when the first rotating ring 22 or the second rotating ring 23 is rotated, the first rotating ring 22 and the second rotating ring 23 are rotated synchronously.

[0038] In one embodiment, Figure 1 As shown, a first rubber sleeve 32 is provided on the first handle 3, a second rubber sleeve 33 is provided on the second handle 4, a first mounting block 34 is provided at the outer end of the first handle 3, a first pull ring 36 is provided at the outer side of the first mounting block 34, a second mounting block 35 is provided at the outer end of the second handle 4, a second pull ring 37 is provided at the outer side of the second mounting block 35, the first rubber sleeve 32 and the second rubber sleeve 33 have an anti-slip effect, which is convenient for the user to train the wrist, and the user's arm can be stretched by holding the first pull ring 36 and the second pull ring 37 with both hands and stretching them outwards.

[0039] The above embodiment discloses an elastic force-assisted training device. When in use, when wrist training is needed, the user holds the first handle 3 and the second handle 4 with both hands and rotates them in relative directions.

The second slider 19 can limit the rotation of the second pull block 2 in the second slide groove 17, so that the rotating disk 6 in the second pull block 2 rotates alone. During the rotation of the rotating disk 6, the connecting block 7 squeezes the first spring 9, and resistance is generated by the first spring 9 to achieve the effect of wrist training. When arm stretching training is needed, the user holds the first pull ring 36 and the second pull ring 37 with both hands and stretches them outwards. The first handle 3 and the second handle 4 are pulled relatively to pull the second spring 10 apart, and the first slider 16 slides in the first slide groove 14, and the second slide block 19 slides in the second slide groove 17, and the arm strength stretching training effect is achieved through the resistance of the second spring 10 itself. When adjusting the resistance, the first rotating ring 22 is rotated, and the first rotating ring 22 moves inward on the left-handed thread 12, and the first connecting ring 24 moves synchronously, so that the moving block 31 in the first connecting ring 24 drives the first pulling block 1 to squeeze the second spring 10 inward, and the second rotating ring 23 is rotated, and the second rotating ring 23 moves inward on the right-handed thread 13, and the second connecting ring 25 moves synchronously, so that the moving block 31 in the second connecting ring 25 drives the second pulling block 2 to squeeze the second spring 10 inward, and under the action of the telescopic rod 30, the first rotating ring 22 and the second rotating ring 23 rotate synchronously, and the resistance size can be stably adjusted according to usage requirements.
