The working principle of example 1 is now briefly described:

the player stands on the turntable 101 with the foot portion fitted over the foot ring 104, while the player grasps the tab 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 along with the rotation shaft 102, so that the player standing on the turntable 101 tends to be thrown out of the turntable 101 due to centrifugal force, and the player pulls the pull ring 103 with his or her hands and arms, and stands on the turntable 101 with his or her legs firmly. Thereby achieving the purpose of simulating the whole body force applying state before the teleoperator throws the hammer out. Furthermore, the angle between the rotary table 101 and the horizontal plane is smaller than 90 degrees, so that when the rotary table 101 rotates, a player needs to constantly adjust the leg strength state, the player can stably stand on the rotary table 101, the leg strength state of the player is further simulated when the player rotates the hammer ball before throwing the hammer ball, and the rotating plane and the horizontal plane of the hammer ball form a certain included angle, so that the player can more truly train and throw the hammer ball.

Example 2:

on the basis of the embodiment 1, the included angle between the rotary table 101 and the horizontal plane can be adjusted, so that different levels of training of leg strength of athletes can be achieved.

As shown in fig. 1-4, 7 and 8, a tenon clamping mechanism is further disposed between the turntable 101 and the rotating shaft 102, and includes a tenon clamping block 201 and a tenon clamping seat 202, the tenon clamping seat 202 is provided with a first through hole and a plurality of first tenon grooves 203, the rotating shaft 102 penetrates through the central through hole and is fixedly connected with the tenon clamping seat 202, the plurality of first tenon grooves 203 are uniformly distributed on the outer wall of the tenon clamping seat 202, the turntable 101 is provided with a second through hole 204, the inner wall of the second through hole 204 is provided with a plurality of second tenon grooves 205, one end of each tenon clamping block 201 is embedded into different first tenon grooves 203, the other end of each tenon clamping block 201 is provided with an arc surface 206, the arc surface 206 is slidably connected with the inner wall of the second tenon groove 205, a gap is left between the side wall of each tenon clamping block 201 and the second tenon groove 205, and a gap is left between the inner wall of the second through hole 204 and the outer wall.
