[0021] Reference Figure 1 and Figure 2 comprises a substrate 1, on the surface of the substrate 1 is provided a pull rod assembly 2, the pull rod assembly 2 includes a cylinder 5 and a rotating cylinder 6. As shown in Figure 1 , the cylinder 5 is arranged at the middle position of the substrate 1, and the rotating cylinder 6 is rotatably sleeved on the surface of the cylinder 5 through a rotating bearing for providing rotation of the pull rod member 7. In this way, flexible rotation can flexibly change the position of the pull rod member 7 during stretching. The surface of the rotating cylinder 6 is rotatably connected with a pull rod member 7. The pull rod member 7 includes a pull rod body 9. One end of the pull rod body 9 is provided with a telescopic groove 10 for limiting the telescopic rod 11. The telescopic rod 11 is movably connected inside the telescopic groove 10. The telescopic rod 11 can be in the shape of a cylinder 5 or a square rod. The shape of the telescopic rod 11 is not limited here. On the upper surface of the pull rod body 9 is provided a locking bolt 12. Rotating the locking bolt 12 will cause the locking bolt 12 to move downward and closely fit on the surface of the telescopic rod 11 to lock the position of the telescopic rod 11 through friction. The bottom end of the locking bolt 12 passes through the pull rod body 9 and extends to the surface of the telescopic rod 11. The upper surface of the telescopic rod 11 is provided with anti-slip lines for enhancing the anti-slip performance at this position and improving the stability of positioning;

[0022] The other end of the telescopic rod 11 is fixed with a connecting rod 13. Transverse rods 14 perpendicular to the pull rod body 9 are fixedly connected to the sides of the pull rod body 9 and the connecting rod 13. The other end of the connecting rod 13 is fixedly connected to a hand ring 8. The other end of the pull rod member 7 is fixedly connected to a hand ring 8. Before the hamstring stretching training, it is necessary to adjust the position of the telescopic rod 11, and adjust the length of the pull rod body 9 through the position of the telescopic rod 11. Specifically, rotate the locking bolt 12 to make it away from the telescopic rod 11, and then pull the connecting rod 13 to drive the telescopic rod 11 to move inside the limiting groove. After reaching the appropriate position, rotate the locking bolt 12 in the reverse direction to make it fit on the surface of the telescopic rod 11 to lock the position of the telescopic rod 11. After locking the position, it is necessary to place the feet on the foot pedal 18 to stabilize the position of the feet. After straightening the legs, hold the hand rings 8 with both hands, and then exert force from the waist position to the side of the back of the head to straighten the arms and pull. In this way, the two legs will be spread apart. The harder you pull, the more the two legs will be spread apart, thereby specifically targeting the hamstring stretching training for the leg position.
