[0022] When in use, the user sits on the leg stretching chair 2, places both legs on the leg stretching training mechanism 3, and is driven by the servo motor 12 to drive the two leg stretching training mechanisms 3 to rotate slowly, thereby achieving stretching exercise for the user's legs.

[0023] See also Figure 1 , Figure 2 and Figure 3Further, the leg stretching training mechanism 3 includes a main stretching arm 31 and a secondary stretching arm 34 slidably arranged at one end of the main stretching arm 31, a foot ankle limiting support 36 is fixedly arranged at the top of the secondary stretching arm 34, a universal wheel 35 is fixedly installed at the bottom of the secondary stretching arm 34, a central shaft 32 is fixedly arranged at the other end of the main stretching arm 31, a worm gear 33 is fixedly arranged at the bottom end of the central shaft 32, and the worm gear 33 is meshedly arranged on the worm 13, an adjusting pin 38 is threadedly connected to the front of the main stretching arm 31, and an adjusting hole 37 is opened on the surface of the secondary stretching arm 34, and the adjusting pin 38 matches the adjusting hole 37;

[0024] When in use, before stretching training, the user can first loosen and remove the adjustment pin 38, pull out the auxiliary stretching arm 34 to a suitable length, and then screw the adjustment pin 38 into the corresponding adjustment hole 37, so that it is suitable for users with different leg lengths to perform stretching training. During stretching, the main stretching arm 31 drives the auxiliary stretching arm 34 to perform a 90° fan-shaped motion with the central axis 32 as the center. During the movement, the auxiliary stretching arm 34 is supported by the universal wheel 35, and the movement is stable and smooth.

[0025] See also Figure 1 and Figure 4 Further, a battery 14 is fixedly installed inside the power box 4, a charging interface 5 is fixedly installed outside the power box 4, a training switch 9 is fixedly installed on the top of the T-shaped handrail 8, the servo motor 12 is electrically connected to the battery 14 through the training switch 9, and a timer 10 is fixedly installed inside the T-shaped handrail 8;
