At this time, a handrail support rod 16 extending parallel to the bottom rod 12 can be provided on the base 10, and the handrail support rod 16 is slightly bent upward at one end toward the handrail portion 20, so that the top ends of the two handrail rods 22 are fixed to the near-top ends of the handrail support rod 16, so that the two handrail rods 22 can be stably fixed on the base 10, and the base 10 can be further provided with an oblique support rod 17 connected to the handrail support rod 16, and the two ends of the oblique support rod 17 are respectively fixedly connected to the bottom surface of the handrail support rod 16 and the top surface of the bottom rod 12, so as to provide the handrail portion 20 with a better structural support effect.

[0056] The two actuating rods 30 are respectively pivotally connected to the base 10, and a pedal 32 is respectively provided at one end of the two actuating rods 30 which is different from the end pivotally connected to the base 10, wherein a support rod 14 obliquely extending toward one side of the armrest portion 20 can be provided at the end of the bottom rod 12 of the base 10 away from the armrest portion 20, one end of the two actuating rods 30 is respectively pivotally connected to the support rod 14, and the armrest support rod 16 is fixedly connected to the support rod 14 at one end different from the end connected to the armrest rod 22, and a seat 142 can be provided at the top end of the support rod 14.

[0057] The balancing linkage device 40 is disposed between the two actuating rods 30, so that the two actuating rods 30 can swing in opposite directions relative to the base 10. Preferably, please refer to Figure 3The balancing linkage device 40 includes a linkage seat 42 fixed on the support rod 14, a horizontal rotating shaft tube 43 is arranged on the linkage seat 42, a rotating shaft 44 that can rotate relative to the rotating shaft tube 43 is arranged in the rotating shaft tube 43, and a rotating arm 46 is fixedly connected to both ends of the rotating shaft 44, a pivot rod 48 is pivotally connected to one end of the rotating arm 46 different from the one connected to the rotating shaft 44, and the pivot rod 48 is pivotally connected to an opposite actuating rod 30 at one end different from the one connected to the rotating arm 46, and a limiting plate 49 is arranged on the linkage seat 42, which is inclined at an angle relative to the linkage seat 42 and can abut against the two rotating arms 46.

[0058] The two dampers 50 are arranged between the two actuating rods 30 and the base 10. The two ends of each damper 50 are pivotally connected to the base 10 and an opposite actuating rod 30. Preferably, each damper 50 is a hydraulic / pneumatic cylinder, and each has a cylinder body 52 and a telescopic rod body 54. One end of the cylinder body 52 is pivotally connected to a connecting piece 18 protruding and fixed on the support rod 14. One end of the telescopic rod 54 can be telescopically moved into the cylinder body 52 other than the end connected to the base 10, and the other end is pivotally connected to an opposite actuating rod 30.

[0059] Therefore, please cooperate with Figure 2 and Figures 4 to 7 The user can step on the pedals 32 of the two actuating rods 30 with both feet respectively, support the two armrest rods 22 of the armrest part 20 with both hands, lean forward slightly and lie down, and step on the pedals 32 with both feet respectively. In this way, the two actuating rods 30 will pivot relative to the support rod 14 due to the user's stepping. At this time, when the actuating rod 30 on one side pivots downward due to the force of the user's stepping, it can drive the pivot rod 48 pivoted thereto to pivot, and at the same time drive the rotating arm 46 pivoted to the pivot rod 48 to pivot relative to the pivot rod 48, thereby driving the rotating shaft 44 to rotate. In this way, when the rotating shaft 44 rotates, it can drive the rotating arm 46 and the pivot rod 48 on the other side to pivot relative to each other, thereby linking the actuating rod 30 on the other side, so that the two actuating rods 30 can swing in the opposite direction relative to the base 10 through the balancing connection device 40.

[0060] Furthermore, the relative abutment between the rotating arm 46 and the limiting plate 49 can limit the maximum swing angle of the two actuating rods 30 .

[0061] In this way, when the user steps on the two actuating rods 30 to swing in the opposite direction, the damper 50 can be pivoted relative to the actuating rod 30 and the base 10 through the swinging movement of the actuating rod 30, and the telescopic rod 54 of the damper 50 can be telescopically moved relative to the cylinder body 52 to provide a resistance force to resist the user's stepping force, so as to achieve the effect of training the user's leg muscles. In addition, each damper 50 is an adjustable damper 50, which can be provided with an adjustment knob 522 at one end of the cylinder body 52 of each damper 50 close to the base 10 to adjust the damping size of the damper 50, so as to provide the user with different damping sizes to achieve different training effects.

[0062] Since the leg training machine of the present invention utilizes two cylinder-type dampers 50 to provide resistance to the swinging motion of the two actuating rods 30 , the structure of the leg training machine of the present invention can be greatly simplified, thereby achieving the effect of greatly reducing the manufacturing and maintenance costs of the leg training machine.

[0063] See also Figure 7 and Figure 8 When using the leg training machine of the present invention, the user can change the position of the leg muscles to be trained by adjusting the body to different angles and postures, such as Figure 7 As shown, the user simulates the starting posture of a race to train the muscle strength and explosive power of the athlete or user at the start.

[0064] In addition, if Fig. 9 As shown, the user stands upright and steps on the actuating rod 30, so that the leg training machine of the present invention can be used as a general stepper, which can improve the flexibility of use of the leg training machine of the present invention.

[0065] Please cooperate and see Fig.10 The user can also sit on the seat 142 at the top of the support rod 14 so that the user's feet can step on the two actuating rods 30 in turn at a smaller angle. This can be used for rehabilitation of the feet of users with muscle atrophy, thereby expanding the scope of application and applicability of the leg training machine of the present invention.
