The inner wall of the bottom ring 10 is provided with a limiting component, which includes two cylinders 15 fixedly connected to the top of the inner wall of the bottom ring 10. A second spring 14 is fixedly connected to the top of each of the two cylinders 15. A lower pressure block 11 is fixedly connected to the top of the two second springs 14. A stop post 12 is fixedly connected to the left and right sides of the top of the lower pressure block 11. The outer wall of the stop post 12 slides on the inner wall of the bottom ring 10, and the outer wall of the lower pressure block 11 is slidably connected to the inner wall of the bottom ring 10.

[0027] Specifically, first, the device is moved outward from the housing 1, and then the turntable 3 is rotated on the outer wall of the top block. After the turntable 3 unfolds, the inner wall of the outer shell 2 is exposed. Then, the pressing block 11 is pressed down, causing it to move downward and move the stop posts 12 on the left and right sides of the top of the pressing block 11 downward. The stop posts 12 slide on the inner wall of the bottom ring 10, causing them to slide into the inner wall of the bottom ring 10. At the same time, the pressing block 11 presses down, and then the bottom of the pressing block 11... The two fixedly connected second springs 14 are compressed under force, and then the counterweight ring 9 can be fitted onto the outer wall of the bottom ring 10. Then, the number of counterweight rings 9 can be increased or decreased according to the user's needs. Then, the lower pressure block 11 is released, so that the second springs 14 rebound and reset, causing the stop post 12 to slide out of the inner wall of the bottom ring 10 to fix the counterweight ring 9. At the same time, the rubber layer provided on the ring device 8 provides anti-slip treatment for the outer wall of the counterweight ring 9.

The pressing block 5 then slides into the inner wall of the fixed rod 4. The extension rod 7 then moves to the right, sliding along the inner wall of the fixed rod 4 until it reaches the user's designated position. The first spring 13 then rebounds, causing the pressing block 5 to spring back to the slot on the inner wall of the fixed rod 4 and eject, thus fixing the extension rod 7. This allows for adjustment of the handle. Adjusting the handle makes the device suitable for most users, improving its applicability and practicality, and meeting various training needs.

[0030] Working principle: First, take out the device and move it out of the housing 1. Then, rotate the turntable 3 on the outer wall of the top block to unfold the turntable 3, exposing the inner wall of the outer shell 2. Then, press down on the lower block 11 to move it downwards, causing the lower block 11 to move the stop posts 12 on the left and right sides of the top of the lower block 11 downwards. The stop posts 12 slide on the inner wall of the bottom ring 10, allowing them to slide into the inner wall of the bottom ring 10. At the same time, the downward pressure of the lower block 11 compresses the two second springs 14 at the bottom of the lower block 11, allowing the counterweight ring 9 to be fitted onto the outer wall of the bottom ring 10. The number of counterweight rings 9 can be increased or decreased according to the user's needs. Then, release the lower pressure block 11, causing the second spring 14 to rebound and reset, allowing the stop post 12 to slide out of the inner wall of the bottom ring 10 to fix the counterweight ring 9. At the same time, the rubber layer provided on the ring device 8 provides anti-slip treatment to the outer wall of the counterweight ring 9. Then, according to the user's needs, press the pressing block 5 to move it downwards, causing the first spring 13 at the bottom of the pressing block 5 to be pressed and contracted by the pressing block 5. Then, after the pressing block 5 slides into the inner wall of the fixing rod 4, move the extension rod 7 to the right, allowing the extension rod 7 to slide on the inner wall of the fixing rod 4 and reach the user's designated position. Then, the first spring 13 rebounds, causing the first spring 13 to drive the pressing block 5 to rebound to the slot opened in the inner wall of the fixing rod 4 and push it out, fixing the extension rod 7 and realizing the adjustment of the device.
