[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example

[0024] See Figures 1 to 4 As shown, a leg training device includes a first leg training arm 1, a second leg training arm 2, a rotating shaft 3, a first leg guard 4, a second leg guard 5 and a reset torsion spring; in this embodiment, the first leg training arm, the second leg training arm, the first leg guard and the second leg guard are all plastic structures. The reset torsion spring is a conventional structure of the prior art, which is simply applied and is mainly used to reset the first leg training arm 1 and the second leg training arm 2 to expand into a V shape in actual application.

[0025] During installation, one end of the first leg-building arm and the second leg-building arm are attached and connected through a rotating shaft; the reset torsion spring is sleeved on the rotating shaft, and the two ends of the reset torsion spring are respectively buckled on the first leg-building arm and the second leg-building arm; the first leg-building arm and the second leg-building arm are unfolded in a V shape under the action of the reset torsion spring; the first leg guard is fixed on the side of the first leg-building arm away from the second leg-building arm through a screw; the second leg guard is fixed on the side of the second leg-building arm away from the first leg-building arm through a screw. In this embodiment, the screw can be a disc-shaped nut or a round nut with stripes, which is convenient for twisting operation, conducive to disassembly and replacement of position, improves the convenience of operation, and is highly practical.

[0026] In actual application, in order to facilitate the position adjustment operation, the first leg-building arm and the second leg-building arm are provided with a plurality of mounting holes 6; the first leg guard and the second leg guard are fixed to different mounting holes by screws to achieve position adjustment. That is, the positions of the first leg guard and the second leg guard can be adjusted as needed to meet the use requirements of different users, which is convenient to operate and highly practical.

[0027] In order to better protect the legs, the outer sides of the first leg guard and the second leg guard are arc-shaped.

[0028] In order to better observe the number of times of fitness, a counting sensor and a display screen connected to the counting sensor are arranged on the first leg-building arm or the second leg-building arm. In this embodiment, the counting sensor and the display screen are conventional structures of the prior art. When in use, when the first leg-building arm and the second leg-building arm are closed, the counting sensor senses and counts once, and displays it on the display screen, so that the user can intuitively check his or her own exercise situation. Therefore, it is not recorded in detail, but simply applied.

[0029] The utility model has positive effects: the structure of the utility model is reasonably arranged. When in use, the leg fitness device is placed between the two legs, and the inner sides of the two legs are respectively abutted against the first leg guard plate and the second leg guard plate. When in use, the two legs are compressed inwardly, and the first leg fitness arm and the second leg fitness arm are rotated around the rotating shaft rod, and the reset torsion spring is compressed. When the two legs move outward, the first leg fitness arm and the second leg fitness arm are reset under the action of the reset torsion spring. In this reciprocating manner, the leg strength training is realized. The utility model is convenient to use, stable and reliable, and is also conducive to reducing assembly and processing costs, and has strong practicality.

[0030] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification can also be directly processed according to existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.
