[0033] One specific application of the embodiment is:

[0034] When the staff needs to use the device, the user makes the telescopic spring 105 reciprocate by using the foot pedal 106 to achieve the training of the user's leg strength. In the process of the movement of the telescopic spring 105, the steel wire rope 210 will be moved. At this time, the coil spring 206 will be continuously tightened or loosened to the steel wire rope 210 through the vertical line wheel 209 due to the elastic force. When the user's leg strength is exhausted, the foot pedal 106 will be quickly reset due to the large elastic force of the telescopic spring 105. When the foot pedal 106 quickly moves to the right, the vertical line wheel 209 will be moved by pulling the steel wire rope 210. Since the friction between the multiple turns of the steel wire rope 210 wound on the vertical line wheel 209 is large, the steel wire rope 210 is difficult to quickly drive the vertical line wheel 209 to rotate quickly, thereby quickly moving the rotating shaft 204 to the right to quickly move the storage box 203 in the sliding groove 202. The force of the right movement of the storage box 203 is greater than the elastic force of the telescopic spring two 208, so the whole storage box 203 will quickly move to the right. When the rotating shaft 204 moves to the position of the clamping block 211 and the ratchet wheel 205 is clamped by the clamping block 211, the ratchet wheel 205 will no longer rotate, thereby the rotating shaft 204 will no longer rotate. The stop of the rotating shaft 204 will stop the movement of the vertical line wheel 209, thereby timely pulling the foot pedal 106 through the steel wire rope 210 to prevent it from hurting the user. The user needs to wear the elastic band two 303 and the elastic band one 301 during the training process. After the elastic band two 303 passes through the fixed block 309 on the elastic band one 301, it is pulled out from the limiting ring 302, and the clamping block two 310 is clamped into the positioning hole 304. When the elastic band two 303 slides outward, the fixed block 309 is fixed in the limiting ring 302, thereby preventing the elastic band two 303 from falling off by itself. The telescopic spring three 306 will always resist the sliding rod 307 due to the elastic force, thereby preventing the sliding rod 307 from being separated from the fixed block 309. When the fixed block 309 needs to be replaced as a whole, the top block 308 is pressed at the same time. The movement of the top block 308 will resist the sliding rod 307 to make it separate from the inside of the fixed block 309, thereby the fixed block 309 can be removed as a whole. When the position of the sliding block 104 needs to be replaced, the positioning rod 313 on both sides of the sliding rail 101 is pulled downward at the same time to make the positioning rod 313 separate from the positioning hole two 311, so that the sliding block 104 can be slid. After the adjustment is completed, the positioning rod 313 is released. The spring 314 will automatically drive the positioning rod 313 to reset and clamp into the positioning hole two 311 to fix the sliding block 104.
