[0024] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0025] See also Figure 1-5 The utility model provides a technical solution: a traction and stretching exercise machine based on sports human science, including a fixed support plate 1, an adjustment structure and a stretching structure. A sliding support plate 2 is provided on one side of the fixed support plate 1. The adjustment structure includes a sliding plate 10, a spring 11, a clamping plate 13, a second spring 14 and a clamping block 15. The sliding plate 10 is slidably connected to the inside of the fixed support plate 1. The sliding plate 10 is fixedly connected to the sliding support plate 2. The clamping plate 13 is slidably connected to the inside of the fixed support plate 1. The spring 11 is fixedly connected between the clamping plate 13 and the sliding plate 10. There are two clamping blocks 15, which are slidably connected to both sides of the clamping plate 13 respectively. The second spring 14 is fixedly connected to the top of the clamping block 15. The top of the second spring 14 is fixed to the clamping plate 13. The fixing support plate 1 is connected and a plurality of slots 12 adapted to the block 15 are equidistantly provided on the fixing support plate 1. The block 15 is moved upward to disengage from the slot 12, thereby moving the position of the card plate 13. After the card plate 13 is moved to a suitable position, the block 15 is released. Due to the action of the spring 14, the block 15 returns to its original position and enters into the corresponding slot 12, thereby completing the fixation of the card plate 13. Moving the card plate 13 to a different position can change the stretching degree of the spring 11, thereby changing the pulling force required to move the sliding support plate 2 to the farthest point. The pulling force can be adjusted according to the conditions of different users through the adjusting device, thereby solving the problem that the pulling force required for stretching is too large due to the inconvenience of adjusting the device, which may cause muscle damage to the user.

[0026] Furthermore, the stretching structure includes a bottom support plate 3, a pull rope 7, a fixed plate 8, a handle 9 and a fixed pulley 16. The bottom support plate 3 is fixedly connected to the bottom of the fixed support plate 1, the sliding support plate 2 is slidably connected to the bottom support plate 3, the fixed pulley 16 is rotatably connected to the inside of the bottom support plate 3, the pull rope 7 is arranged on the outer surface of the fixed pulley 16, the pull rope 7 is fixedly connected to the sliding support plate 2, the fixed plate 8 is fixedly connected to the surface of the fixed support plate 1, the handle 9 is slidably connected to the fixed support plate 1, and the end of the pull rope 7 away from the sliding support plate 2 is fixedly connected to the handle 9. Pulling the handle 9 drives the pull rope 7 to move, and the action of the fixed pulley 16 can drive the sliding support plate 2 to move, and drive the sliding plate 10 to move inside the fixed support plate 1, and at the same time causes the spring to stretch. When the sliding support plate 2 moves to the farthest point, the pulling force on the handle 9 is reduced, and the spring 11 drives the sliding support plate 2 back to its original position, so that the stretching movement is realized in this reciprocating manner, which is convenient to use.

[0027] Secondly, the bottom of the fixed support plate 1 is fixedly connected to multiple bottom supports 4, the bottom of the sliding support plate 2 is fixedly connected to a movable bracket 5, the bottom of the movable bracket 5 is provided with a roller 6, the top of the sliding support plate 2 is fixedly connected to a tripod 18, and the tops of the fixed support plate 1 and the sliding support plate 2 are both fixedly connected to anti-skid pads 17 for anti-skid. The movement of the sliding support plate 2 is facilitated by the rollers 6, the anti-skid pads 17 can increase friction, and the use is safer and more stable. The bottom support 4 can ensure the stability of the placement of the device and improve the safety of use.

[0028] Working principle: Move the card block 15 upward to disengage the card slot 12, and then move the position of the card plate 13. After moving the card plate 13 to the appropriate position, release the card block 15. Due to the action of the spring 14, the card block 15 returns to its original position and enters the corresponding card slot 12 to complete the fixation of the card plate 13. Moving the card plate 13 to different positions can change the stretching degree of the spring 11, and then change the pulling force required for the sliding support plate 2 to move to the farthest point. Pulling the handle 9 drives the pull rope 7 to move, and the action of the fixed pulley 16 can drive the sliding support plate 2 to move, and drive the sliding plate 10 to move inside the fixed support plate 1, while causing the spring to stretch. When the sliding support plate 2 moves to the farthest point, the pulling force on the handle 9 is reduced, and the spring 11 drives the sliding support plate 2 back to its original position, and the stretching movement is realized in this reciprocating manner.

[0029] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
