[0005] The base has rotating grooves on both sides of the top of the base, pedals are rotatably connected in the two rotating grooves through rotating shafts, moving blocks are slidably provided at the bottom of the two pedals through sliding grooves, elastic mechanisms for allowing the pedals to bounce are provided between the two moving blocks and the base, and an adjusting mechanism for adjusting the elastic force of the elastic mechanism is provided inside the base.

[0006] Preferably, the elastic mechanism includes a connecting rod which is rotatably connected to the bottom of the two moving blocks on the same side through a rotating shaft, a disc is fixed to the bottom of the connecting rod, a guide column is fixed to the bottom of the disc, a sliding groove is provided at the top of the base directly below the guide column, a sliding block slides inside the sliding groove, a guide groove is provided on the sliding block, the guide column is inserted into the guide groove, and a spring is provided on the outside of the guide column between the disc and the sliding plate.

[0007] Preferably, the adjustment mechanism includes a rectangular groove inside the base, which is opened on one side of the two sliding grooves. The rectangular groove is connected to the sliding groove. A rectangular block is provided in the rectangular groove. One side of the rectangular block is fixedly connected to the sliding block. A screw is provided in the rectangular groove. The screw passes through the rectangular block and is threadedly connected to the rectangular block. The bottom end of the screw is rotatably connected to the rectangular groove through a rotating shaft, and the top end of the screw passes through the base.

[0008] Preferably, a fixing block is fixed to one side of the base, a supporting rod is fixed to the top of the fixing block, and a handle is installed on the supporting rod.

[0009] Preferably, a baffle is fixed on one side of the top of the base, and the baffle is arranged at an angle.

[0010] Preferably, a non-slip pad is provided at the bottom of the base.

[0011] Preferably, the tops of the two pedals are provided with anti-slip grooves.

[0012] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0013] 1. By stepping on the pedal, the pedal will drive the rotating column to move downward, and the rotating column will drive the disc and the guide column to move downward. The guide column will slide downward through the guide groove on the sliding block, and the spring between the disc and the slider will be squeezed. The upward rebound force of the spring after being squeezed can exercise the legs, thereby realizing the leg exercise function.

[0014] 2. By rotating the screw, the screw drives the rectangular block to move upward, and then drives the sliding block to move upward. However, the pedal will not continue to rotate upward due to the obstruction of the baffle, thereby squeezing the spring, causing the resistance of the spring to increase. At this time, more force is required to step on the pedal. When the elastic force of the elastic mechanism needs to be reduced, the screw can be reversed, thereby realizing the function of adjusting the resistance of the elastic mechanism.

[0026] Through the above technical solution:

[0027] When using the leg exerciser, the user first sits on the bed, places the leg exerciser on the ground in front of the user, places both feet on the two pedals 4 respectively, holds the handles with both hands, and steps on the pedals 4 with both feet alternately. The pedals 4 will drive the rotating column to move downward, and the rotating column will drive the disc 8 and the guide column 10 to move downward. The guide column 10 will slide downward through the guide groove 13 on the sliding block 12, and the spring 9 between the disc 8 and the slider will be squeezed. The upward rebound force of the spring 9 after being squeezed can exercise the legs, thereby realizing the leg exercise function.

[0028] Embodiment 2

[0029] Reference Figure 3 As shown, a leg exerciser comprises:

[0030] An adjusting mechanism for adjusting the elastic force of the elastic mechanism is arranged inside the base 1 .

[0031] Furthermore, the adjustment mechanism includes a rectangular groove 14 provided on one side of the two sliding grooves 11 inside the base 1, the rectangular groove 14 is connected to the sliding groove 11, a rectangular block 15 is provided in the rectangular groove 14, one side of the rectangular block 15 is fixedly connected to the sliding block 12, a screw 16 is provided in the rectangular groove 14, the screw 16 passes through the rectangular block 15 and is threadedly connected to the rectangular block 15, the bottom end of the screw 16 is rotatably connected to the rectangular groove 14 via a rotating shaft, the top end of the screw 16 passes through the base 1, and the screw 16 is rotated, the screw 16 drives the rectangular block 15 to move upward, and then drives the sliding block 12 to move upward, and the pedal 4 will not continue to rotate upward due to the obstruction of the baffle 2, thereby squeezing the spring 9, so that the resistance of the spring 9 becomes larger, and at this time, more force is required to step on the pedal 4, and the resistance of the elastic mechanism can be adjusted in this way.

[0032] Furthermore, a fixing block 5 is fixed to one side of the base 1, a support rod 6 is fixed to the top of the fixing block 5, and a handle is installed on the support rod 6 to facilitate the user to ensure stability.

[0036] Through the above technical solution:

[0037] During use, when the user feels that the elastic force is too small and needs to increase the elastic force of the elastic mechanism, the user rotates the screw 16, and the screw 16 drives the rectangular block 15 to move upward, thereby driving the sliding block 12 to move upward. The pedal 4 will not continue to rotate upward due to the obstruction of the baffle 2, thereby squeezing the spring 9, making the resistance of the spring 9 larger. At this time, more force is needed to step on the pedal 4. When the elastic force of the elastic mechanism needs to be reduced, the screw 16 can be reversed, thereby realizing the function of adjusting the resistance of the elastic mechanism.
