[0035] The drive device 6 includes a rotating motor, each of which is provided with a rotating disk perpendicular to the foot frame 2. The rotating motor can cooperate with the rotating disks via a gear assembly to drive the two rotating disks to rotate in the same or opposite directions. The rotating disks are perpendicular to the foot frame 2. Each rotating disk is provided with a fixed hinge point for articulating the left and right pedal assemblies 4 and 8, respectively, thereby driving the rear ends of the left and right pedal assemblies 4 and 8 to perform circular motion in the vertical direction. In actual use, the vertical direction refers to the direction in which the rotating disks are perpendicular to the foot frame 2 when the foot frame 2 is parallel to the horizontal. As the angle of the foot frame 2 changes, the rotating disks remain perpendicular to the foot frame 2. In one embodiment, the fixed hinge points on the two rotating disks are spaced 180 degrees apart along the circumference, thereby achieving asynchronous movement of the left and right pedal assemblies 4 and 8, creating a stepping effect.

[0036] Combine Figures 8 and 9As shown, the pedal housing includes a pedal fixing plate 4-3 and a pedal assembly upper shell 4-1 and a pedal assembly lower shell 4-6 arranged above and below the pedal fixing plate 4-3.

The pedal fixing plate 4-3 is provided with a through slot for mounting the scraping assembly 4-4, and the drive rod 4-2 is hinged on the rotation shaft 4-3-6. The pedal fixing plate 4-3 is provided with a sliding slot 4-3-3 below the through slot, and pulleys 4-4-2 are provided on both sides of the scraping assembly 4-4 for sliding in the sliding slot 4-3-3. The pedal assembly upper shell 4-1 is formed with a storage space suitable for placing the sole of the foot, and the storage space is located above the through slot. The foot pedal fixing plate 4-3 of the lower shell user specifically includes a fixed plate surface 4-3-1, a slide groove fixing part 4-3-2, a sliding groove 4-3-3, a rotating fixed seat 4-3-4, a rotating shaft sleeve 4-3-5 and a rotating shaft 4-3-6, wherein the through groove is arranged on the fixed plate surface 4-3-1, the slide groove fixing part 4-3-2 is used to hinge the slider 4-5, and the sliding groove 4-3-3 is used to cooperate with the pulley 4-4-2 on the scraping assembly 4-4; the left and right sides of the rotating fixed seat 4-3-4 are hinged together with a rotating shaft sleeve 4-3-5, and the rotating shaft 4-3-6 is suitable for rotating and inserting into the rotating shaft sleeve 4-3-5. The two ends of the rotating shaft 4-3-6 are respectively connected to the fixed hinge point of the rotating disk and the left foot pedal support seat 2-2 or the right foot pedal support seat 2-4. Driven by the rotating disk, the rear ends of the left pedal assembly 4 and the right pedal assembly 8 follow the rotating disk to make circular motion, and at the same time slide in the circular track of the left foot pedal support seat 2-2 or the right foot pedal support seat 2-4 to maintain the stability of the left pedal assembly 4 and the right pedal assembly 8.

[0037] Combine Figure 10As shown, the scraping assembly 4-4 includes a scraping movable part 4-4-1 suitable for exposing the through groove. Two pulleys 4-4-2 are respectively provided on the left and right sides of the scraping movable part 4-4-1 for sliding in the sliding groove 4-3-3 of the foot pedal housing. Connecting plates are also provided on both sides of the scraping movable part 4-4-1 for hinged connection with the driven rod 4-7. The pulleys 4-4-2 are connected via a rolling shaft 4-4-3. A plurality of scraping protrusions are provided above the scraping movable part 4-4-1 for acting on the bottom of the user's foot. The two pulleys 4-4-2 provided on both sides of the scraping movable part 4-4-1 can enable it to slide smoothly in the sliding groove 4-3-3. A driven rod 4-7 is hinged on both sides of the scraping assembly 4-4, and an active rod 7 is hinged on both sides of each scraping assembly 4-4 of the foot fixing frame 2. The other end of the active rod 7 is hinged to the driven rod 4-7, so that when the pedal housing moves, the active rod 7 and the driven rod 4-7 synchronously drive the scraping assembly 4-4 to slide back and forth in the through groove. Here, a crank slider 4-5 structure is formed by the driven rod 4-7, the active rod 7 and the scraping movable part 4-4-1, so that when the driving device 6 is working, it can synchronously drive the scraping movable part 4-4-1 to slide back and forth in the sliding groove 4-3-3 to perform scraping.

[0038] In this embodiment, the driving device 6 drives the foot pedal assembly to move, thereby making the scraping assembly 4-4 move forward and backward, and the driving rod 4-2 connects the foot pedal assembly and the leg side kneading device. When the foot pedal assembly performs a walking action similar to a bicycle, it drives the scraping assembly 4-4 and the leg side kneading device to work simultaneously, so as to achieve the effects of scraping and kneading, thereby realizing diversified massage.
