[0002] In the discus throwing sport, the more traditional training method is to throw the discus by the thrower in an open area. However, this method requires the discus after throwing to be transported back, which is inconvenient for training.

[0003] In 2006, Ocean University of China proposed a discus throwing simulation training device, with the publication number of CN1876205A. This device sets an inclined annular track, and a counterweight sliding device is arranged on the annular track. The user applies force to the counterweight sliding device on the track to make it slide on the annular track, so as to achieve the purpose of simulation training.

[0004] However, after years of development of the above discus comprehensive training device, its overall structure has not changed significantly. After long-term use, users have summarized its disadvantages: 1. The contact structure between the counterweight sliding device and the annular track is unstable, and the counterweight sliding device is prone to radial shaking on the annular track, affecting the training experience; 2. The existing such devices do not set a vertical adjustment device or set the vertical adjustment device at the front side of the training device. This structural setting interferes with the trainers. When the front knees of the trainers bend, it is easy to touch the support rod; 3. The height adjustment device mostly adopts a hand-crank structure, and the trainer needs to squat down and turn the hand crank to achieve lifting, which is inconvenient to operate.
