[0015] The present invention will be further described in detail below with reference to embodiments: Example 1 like Figure 1-6 As shown, this utility model provides a leg stretching exercise device, including a fixed plate 1. An exercise structure 2 is provided on the top surface of the fixed plate 1, and a support mechanism 3 is provided on the top surface of the exercise structure 2. The exercise structure 2 includes a first lifting groove 201, a second lifting groove 202, and a footrest 203. The first lifting groove 201 and the second lifting groove 202 are fixedly connected to both sides of the top surface of the fixed plate 1. A support plate is fixedly connected inside the first lifting groove 201. A lead screw 204 is rotatably connected inside the first lifting groove 201 and the support plate. A drive motor 205 is fixedly connected inside the first lifting groove 201, and the output shaft of the drive motor 205 is fixedly connected to one end of the lead screw 204. A sliding rod 206 is fixedly connected inside the second lifting groove 202, and the first lifting groove 201 and the second lifting groove 202 are slidably connected inside each other. A lifting block 207 is attached. One lifting block 207 is threadedly connected to a lead screw 204, and the other lifting block 207 is slidably connected to a slide rod 206. A support frame 208 is fixedly connected to the sides of the two lifting blocks 207. An adjusting rod 209 is fixedly connected inside the support frame 208. A footrest 203 is slidably connected to the outer surface of the adjusting rod 209. A rod groove 210 is linearly arrayed on the top surface of the footrest 203. An L-shaped rod 211 is rotatably connected to both sides inside the rod groove 210. A support block 212 is fixedly connected to the bottom surface of the footrest 203. A magnet is fixedly connected to the bottom end of the support block 212. A telescopic rod 213 is rotatably connected to both sides inside the rod groove 210. A spring 214 is sleeved on the outer surface of the telescopic rod 213. One end of the telescopic rod 213 is rotatably connected to the L-shaped rod 211.
[0016] In this embodiment, the exercise device is fixedly connected to the ground by a fixing plate 1 to support and fix the entire device. When performing leg stretching exercises, the user stands on the fixing plate 1 and pulls the footrest 203 according to their own standing position. The footrest 203 slides along the adjusting rod 209. After the footrest 203 is adjusted to a suitable position, it is rotated. The footrest 203 drives the support block 212 and the magnet to rotate. The magnet is attracted to the support frame 208 to restrict the rotation of the footrest 203. The restricted rotation of the footrest 203 makes it easier for the user to place their feet on it. When the user places their feet on the footrest 203, it drives multiple L-shaped rods 211 to rotate. When the L-shaped rods 211 rotate, they drive the telescopic rod 213 and the spring 214 to retract. When one end of the L-shaped rod 211 rotates into the rod groove 210, the user's foot comes into contact with the footrest 203, and the footrest 203 supports the user's feet. The other end of the L-shaped rod 211 contacts the user's foot, thus restricting the movement of the user's foot. At this time, the drive motor 205 is started to drive the lead screw 204 to rotate. The lifting groove 201 and the support plate are connected to the lead screw 204 through bearings to improve the rotational stability of the lead screw 204. When the lead screw 204 rotates, it drives a lifting block 207 to rise. The lifting block 207 drives the user's foot to rise through the support frame 208, the adjusting rod 209 and the footrest 203, thereby stretching the user's legs. When the support frame 208 rises, it drives another lifting block 207 to rise. The slide rod 206 is connected to the lifting block 207 to improve the lifting stability of the lifting block 207. When the footrest 203 drives the user's foot to a suitable height, the drive motor 205 is turned off to fix the height of the footrest 203, so that the user can continue to stretch the legs.
[0017] Example 2 like Figure 1-6 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the support mechanism 3 includes a connecting plate 301 and a pull ring plate 302. The connecting plate 301 is fixedly connected to the top surface of the first lifting groove 201 and the second lifting groove 202. Adjustment grooves 303 are fixedly connected to both sides of the connecting plate 301. Limiting holes 304 are linearly arrayed on the side of the adjustment groove 303. An adjustment block 305 is slidably connected inside the adjustment groove 303. A hand support 306 is fixedly connected to the side of the adjustment block 305. A sponge is fixedly connected to the top surface of the hand support 306. A limiting rod 307 and a magnetic sheet are fixedly connected to the side of the pull ring plate 302. A through hole is opened on the side of the adjustment block 305. The limiting rod 307 cooperates with the limiting hole 304 and the through hole.
[0018] In this embodiment, the connecting plate 301 is connected to the first lifting groove 201 and the second lifting groove 202 respectively to improve the stability of the first lifting groove 201 and the second lifting groove 202. The connecting plate 301 is also connected to the adjusting groove 303 to fix the adjusting groove 303. Before performing leg stretching exercises, the user pulls the hand support 306 according to their own height to drive the adjusting block 305 to slide in the adjusting groove 303, thereby adjusting the height of the hand support 306. When the hand support 306 is adjusted to a suitable height, the pull ring plate 302 is pushed to drive the limiting rod 307 to be inserted into the limiting hole 304 and the through hole inside the adjusting block 305. The limiting rod 307 fixes the height of the adjusting block 305 and the hand support 306. The magnetic sheet connected to the side of the pull ring plate 302 is attracted to the adjusting groove 303 to prevent the limiting rod 307 from falling out of the limiting hole 304 and the through hole during use, thereby improving the safety of the exercise device. When performing leg stretching exercises, the two hand supports 306 support the user's arms, improving the user's body stability. The sponge connected to the top surface of the hand supports 306 can improve the user's comfort. A controller is connected to the top surface of one hand support 306. An external power supply is connected to the controller and the drive motor 205 respectively. The controller allows the user to control the start and stop of the drive motor 205.
