Connecting blocks are symmetrically installed at the center of the outer top surface of the pedal. A round rod is fixed between the two connecting blocks. A tension rope is wound around the outer wall of the round rod. One end of the tension rope passes through the inside of the two pull rings and is fixedly connected to the outer wall of the two square blocks, while the other end is fixedly connected to a handle.

[0008] As a further technical solution of this utility model, one end of the tension rope passes through the inside of the two pull rings and is fixedly connected to the outer side wall of the two blocks, while the other end is fixedly connected to a handle. The outer top surface of the two connecting blocks is fixed with a U-shaped sleeve, and the two ends of the handle are respectively engaged in the inner side of the two U-shaped sleeves.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-3 This utility model provides an adjustable leg fitness training device: it includes two sets of symmetrical support plates 1, and each set of support plates 1 has a supporting block 104 fixed on its outer bottom surface. The outer bottom surface of each of the two supporting blocks 104 is provided with a through screw hole 105. Tightening the bolt in the screw hole 105 can fix the two sets of support plates 1 on the training ground, thereby ensuring stability during subsequent use and facilitating disassembly. The outer top surfaces of the two sets of support plates 1 are respectively fixed with a horizontal plate 101 and a horizontal block 102. The left end of the outer top surface of the horizontal plate 101 is fixed with a vertical plate 103. The user can sit on the horizontal plate 101 and lean against the vertical plate 103 to carry out fitness training. At the same time, handrails are symmetrically installed on the horizontal plate 101 to facilitate support for the user during training.

[0025] A stretching training component 2 is provided between the horizontal plate 101 and the horizontal block 102. The stretching training component 2 includes a pedal 201 located between the horizontal plate 101 and the horizontal block 102. A square base 202 is fixed to the outer wall of the pedal 201 on the side away from the horizontal plate 101. A connecting plate 203 is fixed to the right outer wall of the square base 202 by bolts. A connecting plate 204 is fixed to the left outer wall of the horizontal block 102 by bolts. Both the connecting plate 204 and the outer wall of the horizontal block 102 have through-holes 205. A sliding rod 206 is slidably connected inside the two holes 205. One end of the sliding rod 206 is fixedly connected to the connecting plate 203, while the other end extends to the right outer wall of the horizontal block 102. A return spring is fitted on the outer wall of the sliding rod 206. 207. The two ends of the return spring 207 are fixedly connected to the connecting plate 1 203 and the connecting plate 204 respectively. The horizontal plate 101 and the horizontal block 102 are fixed together with symmetrically arranged guide rods 403. The two ends of the pedal 201 are slidably sleeved on the outer walls of the two guide rods 403 respectively. When in use, the user can push the pedal 201 with his / her legs to move laterally along the guide rods 403, so that the pedal 201 moves away from the horizontal plate 101 and the slide rod 206 slides inside the round hole 205, thereby compressing the return spring 207 to train the user's legs. At the same time, the bolt connection method allows the return spring 207 to be replaced when it loses its elasticity after long-term use, thereby ensuring the continuous normal use of the device.

[0026] Square blocks 3 are fixed on the outer walls of both the front and rear sides of the pedal 201. Pull rings 301 are fixed on the outer walls of both the front and rear sides of the cross block 102. Connecting blocks 302 are symmetrically installed at the center of the outer top surface of the pedal 201. A round rod 303 is fixed between the two connecting blocks 302. A tension rope 304 is wound around the outer wall of the round rod 303. One end of the tension rope 304 passes through the inside of the two pull rings 301 and is fixedly connected to the outer wall of the two square blocks 3. The other end is fixedly connected to a handle 305. A U-shaped sleeve 306 is fixed on the outer top surface of the two connecting blocks 302. The two ends of the handle 305 are respectively engaged in the inner side of the two U-shaped sleeves 306. When performing arm training, the user can remove the handle 305 from the inside of the U-shaped sleeve 306 and then use the handle 305 to drive the tension rope 304 to move. This, in turn, pulls the pedal 201 laterally through the square block 3 and compresses the return spring 207, thereby achieving the purpose of exercising the user's arms and increasing practicality.

[0027] The outer top surface of the square base 202 has horizontal openings 4 arranged at equal intervals. Each horizontal opening 4 contains a matching counterweight 401. A handle 402 is fixed to the outer top surface of each counterweight 401. The outer sidewalls of the two guide rods 403 have insertion holes 404 arranged in a linear array. A limiting plate 405 is slidably inserted into the insertion hole 404. The weight of the pedal 201 can be increased or decreased by adding or removing the counterweights 401. At the same time, the lateral displacement of the pedal 201 can be adjusted by inserting the limiting plate 405 into the insertion hole 404. Thus, the tension can be adjusted according to the user's actual training needs, thereby increasing the flexibility of the device.

[0028] The working principle of this utility model is as follows: When in use, the device is first fixed on the training ground. Then, the user can sit on the horizontal plate 101 and lean against the vertical plate 103. The user can push the pedal 201 with their legs to move laterally along the guide rod 403, so that the pedal 201 moves away from the horizontal plate 101 and the slide rod 206 slides inside the round hole 205 to compress the return spring 207, so as to train the user's legs.

[0029] At the same time, the user can hold the handle 305 to drive the tension rope 304 to perform a winding motion, and then pull the pedal 201 through the block 3 to perform lateral displacement and compress the return spring 207, so as to achieve the purpose of exercising the user's arms.

[0030] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
