The pedal rotating shaft 5 is arranged at a non-central position in the middle of the outer surface of the installation side plate 1, at the moment, the heights of the pedal rotating shaft 5 relative to the top end or the bottom end are different, and the device can be provided with two pedal heights and is suitable for different crowds.

The center of the reciprocating roller 2 is rotatably provided with a rotating shaft 7, two ends of the rotating shaft 7 extend out of the reciprocating roller 2 and are respectively fixed on the corresponding mounting side plate 1, and a scroll-shaped spring piece 41 in the reciprocating roller 2 is connected with the corresponding rotating shaft 7. The outer ends of the two rotating shafts 7 are provided with shoulders which are abutted against the inner surface of the installation side plate 1, and the outer ends of the rotating shafts 7 extend out of the installation holes of the installation side plate 1 and are fixedly connected with the installation side plate 1 through bolts.

Since the scroll spring 41 is compressed when the reciprocating drum 2 moves forward in the forward direction, the inner end of the scroll spring 41 has a force for pulling the rotation shaft 7 to rotate, and in order to ensure that the rotation shaft 7 can be stably not rotated, an anti-rotation structure is provided, one of the installation side plates 1 is provided with an anti-rotation hexagonal hole 8, and the rotation shaft 7 corresponding to the scroll spring 41 is provided with an anti-rotation hexagonal surface 9 which is installed in cooperation with the anti-rotation hexagonal hole 8. The anti-rotation hexagonal surface 9 is correspondingly sleeved and matched with the anti-rotation hexagonal hole 8, so that the rotation of the rotating shaft 7 can be effectively avoided.

The outer surface of the roller driving belt 3 is provided with anti-skid patterns, so that slipping is not easy to occur when the roller driving belt moves forwards on the ground; in order to ensure that no slip occurs between the roller driving belt 3 and the reciprocating roller 2 when the roller driving belt 3 moves, an anti-slip strip for increasing friction force between the roller driving belt 3 and the outer surface of the reciprocating roller 2 is arranged.

In this embodiment, pedal pivot 5 is by two sections combination, be equipped with the mounting hole seat on the installation curb plate 1, two sections of pedal pivot 5 are respectively by outer tear into in the mounting hole seat, then two sections screw thread butt joint installations, the both ends of pedal pivot 5 stretch out respectively the pedal portion 6 outside the installation curb plate 1, pedal pivot 5 can wind installation curb plate 1 rotates, simultaneously carry out left and right directions spacing through the shoulder between pedal pivot 5 and the installation curb plate 1. The pedal part 6 can be coated with an anti-slip sponge layer.

The top surface and the side surface of the installation side plate 1 are provided with direction indication marks for clearly indicating the forward moving direction.

The working principle of the embodiment is as follows:

Before use, a user sits on the device, the device is placed on the ground in front of the user, the device is adjusted to be in a state shown in fig. 5, the pedal rotating shaft 5 is adjusted to be at a low position, and the forward moving direction is adjusted well; when the scroll spring plate is used, a user steps on the left pedal part and the right pedal part 6, then lower limbs exert force to push the two pedal parts 6 forwards by feet, so that the roller driving belt 3 slides forwards, the two reciprocating rollers 2 rotate forwards, the movement direction of the reciprocating rollers 2 is shown in fig. 7, in the forward movement process of the reciprocating rollers 2, the spring plate clamping seat 42 rotates around the rotating shaft 7, and as the inner end of the scroll spring plate 41 is fixed, the outer end of the scroll spring plate 41 rotates along with the action of the spring plate clamping seat 42, the scroll spring plate 41 is compressed and deformed; when the feet of a user are loosely lapped on the two pedal parts 6, the reciprocating roller 2 is not pressed and released, at the moment, the scroll spring pieces 41 are not pressed any more, the scroll spring pieces 41 recover to deform and reversely push the corresponding reciprocating reverse rotation to back movement, so that the roller driving belt 3 slides backwards, the other reciprocating roller 2 also moves backwards along with the reverse rotation, and at the moment, the feet of the user are lapped on the two pedal parts 6 lightly and back to the initial position along with the pedal parts 6; when the user needs to step on the high position, the device is turned over by 180 degrees and then the front and back directions are adjusted, the state is shown in fig. 8, and at the moment, the front and back positions of the reciprocating roller 2 with the scroll-shaped spring piece 41 are changed, but when the reciprocating roller 2 moves forwards, the rotation directions of the reciprocating roller 2 are the same, and the spring piece clamping seat 42 also enables the scroll-shaped spring piece 41 to be compressed and deformed;

When the front and back directions of the device are reversed, the roller driving belt 3 is pushed to slide forwards by reverse forward movement, at the moment, the spiral spring piece 41 is not pressed and is separated from the rectangular groove when the spring piece clamping seat 42 rotates along with the reciprocating roller 2, at the moment, no matter which position the reciprocating roller 2 rotates to, the spiral spring piece 41 is always in a separated state, and when the lower limb does not apply force to move forwards any more, the device does not fall back; however, when the lower limb of the user applies a force in a reverse direction, so that the device is retracted backward passively, the spring plate clamping seat 42 rotates in a reverse direction, the scroll spring plate 41 contacts the spring plate guide block 46, and slides along the spring plate guide block 46 to pass through the conical guide structure 45 and enter the rectangular groove, so that the scroll spring plate 41 is automatically inserted.

The foregoing has shown and described the basic principles, main features and advantages of the present utility model. It will be understood by those skilled in the art that the present utility model is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present utility model, and various changes and modifications may be made without departing from the spirit and scope of the utility model, which is defined in the appended claims.
