[0074] Reference appendix Figures 1 to 5 In some instances, the connection assembly 500 further includes a rotating seat 510, a third guide member 503, and a connecting member 511.

[0075] Specifically, the rotating seat 510 is fixedly arranged on the top of the sliding seat 504. The rotating seat 510 is provided with a long strip-shaped guide opening for guiding the transmission rope 505, so that the transmission rope 505 moves along the length direction of the guide opening, flexibly matching the pulling direction of the athlete, and at the same time preventing the transmission rope 505 from slipping off the second guide member 502 and the third guide member 503.

[0076] The third guide member 503 is a fixed pulley. The third guide member 503 and the second guide member 502 are relatively rotatably arranged inside the rotating seat 510. The transmission rope 505 passes between the third guide member 503 and the second guide member 502 and extends out through the guide opening. The third guide member 503 and the second guide member 502 cooperate to guide the transmission rope 505 to extend out through the guide opening.

[0077] The connecting member 511 is arranged on one side of the guide opening and is connected to the transmission rope 505. A connecting buckle is arranged at one end of the connecting member 511 away from the guide opening for connecting with the training auxiliary component.

The pusher 506 includes a first rod and a second rod that are parallel to each other. The first rod is slidably disposed on the sliding seat 504 along the length direction of the base 100, and the second rod is provided with tooth patterns. When the athlete pushes the first rod, the second rod pushes the transmission gear 508 along the length direction of the base 100 following the first rod.

[0082] The positioning member 507 is slidably disposed on the sliding seat 504 along the width direction of the base 100. The side wall of the positioning member 507 is provided with tooth patterns. The moving direction of the positioning member 507 is perpendicular to the moving direction of the pusher 506. As the pusher 506 drives the transmission gear 508 to rotate, the transmission gear 508 drives the positioning member 507 to extend into or out of the positioning hole 301.

[0083] The elastic member 509 includes a spring, a compression spring, rubber, etc. The elastic member 509 is disposed between the pusher 506 and the sliding seat 504. The elastic member 509 is used to push the pusher 506 to reset, so that the pusher 506 drives the positioning member 507 to extend into the positioning hole 301 through the transmission gear 508 to complete the positioning.

[0084] When the athlete needs to adjust the relative position between the sliding seat 504 and the base 100, by pressing the pusher 506 to compress the elastic member 509, the pusher 506 drives the positioning member 507 to extend out of the positioning hole 301 through the transmission gear 508. At this time, the sliding seat 504 can slide along the length direction of the base 100.

[0085] Until reaching the appropriate position, the athlete releases the pusher 506 to release the elastic member 509. The elastic member 509 drives the pusher 506 to reset. The pusher 506 drives the positioning member 507 to extend into the positioning hole 301 through the transmission gear 508. At this time, the relative position between the sliding seat 504 and the base 100 is fixed, so as to facilitate the athlete to change the relative position between the sliding seat 504 and the support member 200 according to their different physical signs.

[0086] The present application provides a training machine. Through the flexible adjustment functions of the telescopic component 400 and the connection component 500, the needs of athletes for multiple trainings such as Bulgarian squats, hip bridges, arm stretches, and leg stretches can be met. Athletes can adjust the training machine based on their personal indicators such as height, arm span, and leg-lifting height, so that the training machine has stronger applicability; through the cooperation of the sliding seat 504, the first guide member 501, the second guide member 502, and the transmission rope 505, the resistance of the motor 900 is transmitted to other positions to meet the training needs of athletes; through the cooperation of the positioning hole 301, the pushing member 506, the positioning member 507, and the transmission gear 508, it is convenient for athletes to adjust and control the sliding seat 504 to stay at a suitable position on the base 100 to meet the training needs of athletes; by adjusting the knob 700, it is convenient to control the magnitude of the resistance of the motor 900 to meet the training resistance needs of athletes.
