Now briefly describe the working principle of Embodiment 1:

The athlete stands on the turntable 101 , and the feet are put on the foot ring 104 , while the athlete grasps the pull ring 103 with both hands. The power device 105 drives the rotating shaft 102 to rotate, thereby driving the turntable 101 to rotate. The tension belt rotates together with the rotating shaft 102, so the athlete standing on the turntable 101 tends to be thrown out of the turntable 101 due to the centrifugal force. Stand firm. In this way, it can simulate the state of the whole body before the long-distance mobilizer throws the hammer hard. Further, since the turntable 101 and the horizontal plane are at an angle of less than 90 degrees, while the turntable 101 is rotating, the athlete needs to adjust the state of the legs exerting force at all times, so as to ensure that he stands firm on the turntable 101, which further simulates the athlete throwing out. When the hammer is rotated before the hammer, when the rotation plane of the hammer and the horizontal plane are at a certain angle, the athlete's legs are in a state of force, so that the athlete can train the hammer more realistically.

Example 2:

On the basis of Embodiment 1, in order to be able to adjust the angle between the turntable 101 and the horizontal plane, so as to achieve different levels of training for the leg strength of the athlete.

As shown in Figures 1-4, 7 and 8, a tenon mechanism is further provided between the turntable 101 and the rotating shaft 102, including a tenon block 201 and a tenon seat 202, and the tenon seat 202 is provided with a first tenon block 201.
