[0042] Figure 1 In the embodiment, one pedal 12 and second pedal 22 are in staggered motion state;

[0043] Figure 2 In one embodiment, the first pedal 12 and the second pedal 22 are in a synchronous movement state.

[0044] Both pedals are provided with an upwardly protruding retaining ring 4, which is a rectangular ring and surrounds the periphery of the pedal.

[0045] The motor 6 drives the movement of the two pedals, and the specific structure is as follows:

[0046] Referring to Figures 3-7 ,

[0047] The motor 6 is drivingly connected with a main shaft 8; the motor 6 is located between the two pedals, the motor 6 and the main shaft 8 are vertically arranged, the output shaft of the motor 6 is fixedly connected with a worm 71, the main shaft 8 is installed with a turbine 72, and the worm 71 engages the turbine 72. The motor 6 can drive the worm 71 to rotate forward and reverse, thereby achieving the driving of the main shaft 8 to rotate forward and reverse.

[0048] The turbine 72 and the worm 71 are sleeved with an outer shell, and the outer shell is fixed on the base 5, while the shell of the motor 6 is fixedly connected with the outer shell through screws.

[0049] The two ends of the main shaft 8 are respectively installed with a first rotary disc 11 and a second rotary disc 21;

[0050] Both the first rotary disc 11 and the second rotary disc 21 are circular discs; the main shaft 8 is inserted into the two ends of the first rotary disc 11 and the second rotary disc 21 respectively, and then the end part is fixed by using a clamping spring;

[0051] The sleeve body of the first rotary disc 11 is fixed with the main shaft 8 by using a latch, so that when the main shaft 8 rotates forward or reversely, the first rotary disc 11 rotates synchronously with the main shaft 8;

[0052] The second rotary disc 21 is provided with a shaft sleeve 31 sleeved on the main shaft 8, the shaft sleeve 31 is provided with a gear slot 32 on the circumference, the gear slot 32 is arranged along the circumferential direction of the shaft sleeve 31, and the circumferential angle of the gear slot 32 relative to the shaft sleeve 31 is 180 degrees; in other embodiments, the circumferential angle of the gear slot 32 relative to the shaft sleeve 31 can be 90 degrees, 120 degrees or 150 degrees, etc.

[0053] The main shaft 8 is fixed with a gear lever 33 located in the gear slot 32; the gear lever 33 is fixed on the side wall of the main shaft 8, and in this design, the gear lever 33 is an open elastic latch which is inserted and fixed in the main shaft 8.

[0054] When the motor 6 rotates forward, the gear lever 33 abuts against one end of the gear slot 32, the main shaft 8 drives the gear lever 33 to rotate, the gear lever 33 pushes the shaft sleeve 31 to drive the second rotary disc 21 to rotate, thereby realizing the synchronous swinging of the first rotary disc 11 and the second rotary disc 21;

[0055] When the motor 6 reverses, the main shaft 8 rotates, and the gear lever 33 first rotates along the circumferential direction of the gear slot 32. When the gear lever 33 abuts against the other end of the gear slot 32, the main shaft 8 pushes the second rotating disc 21 to rotate, so as to realize the staggered swinging of the first rotating disc 11 and the second rotating disc 21.

[0056] The swinging structure of the two rotating discs is as follows:

[0057] The first rotating shaft 15 is eccentrically arranged and rotatably connected to the first rotating disc 11. The first rotating shaft 15 is located at the edge of the first rotating disc 11 and is fixed at both ends of the first rotating disc 11 by using a snap spring. The first rotating shaft 15 can rotate relative to the first rotating disc 11.

[0058] Similarly, the second rotating shaft 25 is eccentrically arranged and rotatably connected to the second rotating disc 21. The second rotating shaft 25 is located at the edge of the second rotating disc 21 and is fixed at both ends of the second rotating disc 21 by using a snap spring. The second rotating shaft 25 can rotate relative to the second rotating disc 21.

[0059] The first rotating shaft 15 is fixed to the first pedal 12.

[0060] The second rotating shaft 25 is fixed to the second pedal 22.

[0061] Since the first rotating shaft 15 is eccentrically arranged at the first rotating disc 11 and the first pedal 12 is eccentrically arranged at the first rotating disc 11,

[0062] Since the second rotating shaft 25 is eccentrically arranged at the second rotating disc 21 and the second pedal 22 is eccentrically arranged at the second rotating disc 21,

[0063] The base 5 is provided with a first track 13 for the back-and-forth swinging of the first pedal 12.

[0064] The first pedal 12 is provided with a first sliding rod 14 sliding in the first track 13. The first sliding rod 14 is fixed to the bottom of the first pedal 12. The first track 13 includes two arc-shaped sliding grooves arranged in parallel. The two ends of the first sliding rod 14 slide in the two corresponding arc-shaped sliding grooves. The first track 13 and the first rotating disc 11 are located at both ends of the first pedal 12.

[0065] The base 5 is provided with a second track 23 for the back-and-forth swinging of the second pedal 22.

[0066] The second pedal 22 is provided with a second sliding rod 24 sliding in the second track 23. The second sliding rod 24 is fixed to the bottom of the second pedal 22. The second track 23 includes two arc-shaped sliding grooves arranged in parallel. The two ends of the second sliding rod 24 slide in the two corresponding arc-shaped sliding grooves. The second track 23 and the second rotating disc 21 are located at both ends of the second pedal 22.

[0067] The first track 13 and the second track 23 are both fixed to the base 5.

[0068] Working principle: the motor 6 rotates forward, the main shaft 8 rotates forward through the turbine 72 and the worm 71 drive, at this time the main shaft 8 drives two rotating discs to rotate simultaneously, the two rotating shafts on the two rotating discs are on the same straight line, therefore, when the two rotating shafts rotate in a circle, the front ends of the two pedals are estimated to be the same, and the rear end slide bars of the pedals are passive sliding, so the two pedals swing differently, and the working state is as follows Figure 2 .

[0069] When the motor 6 reverses, the main shaft 8 first rotates relative to the second rotating disc 21, the gear lever 33 first rotates relative to the gear slot 32 in the circumferential direction, when the gear lever 33 abuts against the other end of the gear slot 32, the two rotating shafts of the two rotating discs are not on the same straight line, in the design, the two rotating shafts are separated by a circumferential angle of 180 degrees on the circumference of the rotating disc, the main shaft 8 drives the second rotating disc 21 to rotate, so as to realize the staggered swing of the first rotating disc 11 and the second rotating disc 21, and the working state is as follows Figure 1 .

[0070] Embodiment 2, a pedal type calf massage mechanism, which is different from embodiment 1, as follows Figure 8 The slot wall of the gear slot 32 is adhered with a rubber layer 9;

[0071] As follows Figures 7-8 The gear lever 33 abuts against the rubber layer 9, which has two effects, one is to mute the impact when adjusting the gear, and the other is to reduce the wear of the gear lever 33 when impacting, thereby prolonging the service life.

[0072] The above is only the preferred embodiment of the present application, the protection scope of the present application is not limited to the above embodiment, any technical solution under the idea of the present application belongs to the protection scope of the present application. It should be noted that for ordinary technical personnel in the technical field, some improvements and decorations without departing from the principle of the present application are also considered as the protection scope of the present application.
