[0014] 1. The utility model provides a fixing mechanism, when performing rope skipping exercise, when grasping the handle, the hand is placed at the bottom of the hand strap located on the surface of the handle, and when the shift block is shifted upward, the cylinder drives the tooth block to rotate, and the tooth block meshes with the gear, driving the second rotating rod to rotate, and the rotating second rotating rod drives the middle hand strap to rotate, so that the hand strap is wrapped around the outer wall of the second rotating rod, while the shift block is continuously shifted, the hand strap is pulled to tighten the hand strap on the surface of the handle to fix the hand, and when it is adjusted to a suitable angle, the shift block is stopped, and the torsion spring pulls the hand strap back, at this time the cylinder rotates downward, and when the cylinder moves downward, it drives the extrusion block on the left side of the cylinder to move downward, and the bottom of the extrusion block touches the top of the blocking block, and the blocking block blocks the extrusion block, thereby restricting it, thereby preventing the tightened hand strap from loosening, thereby improving the practicality of the device.
[0015] 2. The utility model provides a reset mechanism. After finishing the rope skipping exercise, it is only necessary to push the round rod at the bottom of the handle. The pushed round rod squeezes and pushes the slider, thereby driving a moving block on one side to move. When the blocking block restricts the squeezing block, the moving block moves away, thereby driving the blocking block to move away, so that the blocking block no longer restricts the squeezing block, so that the cylinder continues to rotate under the drive of the torsion spring, and the hand strap on the surface of the second rotating rod is pulled by the torsion spring, so that the hand strap returns to the surface of the torsion spring in the storage bin. After the torsion spring is twisted to reset, the remaining hand straps are in a relaxed state, so that the hands of the person are no longer restricted, thereby resetting, thereby improving the practicability of the device.
