A second adjustment assembly 8 is installed inside both support plates 4. First, according to the arm length after the user stretches out the arms, use the first adjustment assembly 7 to adjust the position of the fixed rod 5. The user can sit on the seat 2, then place the legs on the corresponding support plates 4, and according to the thickness of the user's legs, use the second adjustment assembly 8 to drive the corresponding two guard plates 42 to move towards each other to clamp and limit the user's legs, and then use the driving assembly 6 to perform stretching training on the user's legs.
[0019] The driving assembly 6 includes a double-sided toothed plate 61, and the double-sided toothed plate 61 is slidably installed on the bottom plate 1.
[0020] By adopting the above technical solution, the double-sided toothed plate 61 slides on the bottom plate 1.
[0021] One end of the double-sided toothed plate 61 is fixedly installed with a sliding rod 65, and the sliding rod 65 is slidably inserted into the bottom plate 1. A spring 66 is sleeved on the sliding rod 65.
[0022] By adopting the above technical solution, the sliding rod 65 drives the double-sided toothed plate 61 to slide on the bottom plate 1 and compresses the spring 66.
[0023] Both bottom ends of the two rotating rods 3 are fixedly installed with gears 62, and the gears 62 are meshed with the double-sided toothed plate 61.
[0024] By adopting the above technical solution, the double-sided toothed plate 61 drives the two gears 62 to rotate synchronously and in opposite directions, and the gears 62 drive the support plates 4 and the user's legs to stretch and separate through the rotating rods 3.
[0025] One end of the sliding rod 65 is fixedly installed with a pull rope 63, and one end of the pull rope 63 is fixedly installed with a handle 64.
[0026] By adopting the above technical solution, the user drives the sliding rod 65 to slide through the handle 64 and the pull rope 63.
[0027] Two pulleys 51 distributed up and down are rotatably installed in the fixed rod 5, and the pull rope 63 contacts the pulley 51.
[0028] By adopting the above technical solution, the pulley 51 facilitates the transmission of the pull rope 63.
[0029] The first adjusting assembly 7 includes a threaded rod 72. The threaded rod 72 is rotatably installed in the bottom plate 1, and the threaded rod 72 is threadedly inserted into the fixed rod 5. One end of the threaded rod 72 is fixedly installed with a first turntable 71.

[0031] Both of the two second adjusting assemblies 8 include a bidirectional lead screw 82. The two bidirectional lead screws 82 are respectively rotatably installed in the support plate 4, and the bidirectional lead screw 82 is threadedly inserted into the corresponding guard plate 42. One end of each of the two bidirectional lead screws 82 is fixedly installed with a second turntable 81.
[0032] By adopting the above technical solution, the second turntable 81 is used to drive the bidirectional lead screw 82 to rotate, and the bidirectional lead screw 82 drives the corresponding two guard plates 42 to slide towards each other to clamp and limit the user's legs.
[0033] Working principle: When the present utility model is in use, first, according to the arm length after the user stretches out the arms, the first turntable 71 is used to drive the threaded rod 72 to rotate, and the threaded rod 72 drives the fixed rod 5 to slide and adjust its position. The user can sit on the seat 2, then place the legs on the corresponding support plates 4, and according to the thickness of the user's legs, the second turntable 81 is used to drive the bidirectional lead screw 82 to rotate, and the bidirectional lead screw 82 drives the corresponding two guard plates 42 to slide towards each other to clamp and limit the user's legs. Then the user drives the sliding rod 65 to slide through the handle 64 and the pull rope 63. The pulley 51 in the fixed rod 5 can facilitate the transmission of the pull rope 63. The sliding rod 65 drives the double-sided toothed plate 61 to slide on the bottom plate 1 and compress the spring 66. The double-sided toothed plate 61 drives the two gears 62 to rotate synchronously and reversely. The gears 62 drive the support plate 4 and the user's legs to stretch and separate through the rotating rod 3, and use the resilience of the spring 66 to make the double-sided toothed plate 61 drive the support plate 4 and the user's legs to reset. In this way, it reciprocates, so as to achieve the purpose of stretching and training the user's arms and legs simultaneously.
