[0033] Multiple mounting shafts 6 are provided, and the top of the mounting shaft 6 is rotatably connected to the bottom of the mounting frame 1;

[0034] Multiple support frames 7 are provided and correspond one-to-one with the mounting shaft 6. The top of the support frame 7 is fixedly connected to the bottom of the mounting shaft 6, and a traveling wheel 8 is rotatably connected inside the support frame 7.

[0035] Multiple locking cards 9 are provided and correspond one-to-one with the support frame 7. The locking cards 9 are rotatably connected to the support frame 7 to lock the walking wheel 8.

[0036] Multiple positioning mechanisms are provided, each corresponding to the mounting shaft 6. One end of the positioning mechanism is connected to the mounting frame 1, and the other end of the positioning mechanism is connected to the support frame 7 for positioning the mounting shaft 6.

[0037] The limiting mechanism is provided in multiple sets and corresponds to the locking card 9. The limiting mechanism is connected to the support frame 7 to limit the locking card 9.

[0038] Example 2

[0039] like Figure 2 As shown, the present invention discloses a portable multi-directional training chair. Compared with Embodiment 1, this embodiment further discloses the structure of the positioning mechanism. The positioning mechanism includes a first end face toothed ring 31, a second end face toothed ring 32, and an adjustment frame 33. The first end face toothed ring 31 is sleeved on the mounting shaft 6 and rotatably connected to the mounting shaft 6. The top of the first end face toothed ring 31 is fixedly connected to the bottom of the mounting frame 1. The second end face toothed ring 32 is sleeved on the mounting shaft 6 and slidably connected to the mounting shaft 6 along the axial direction of the mounting shaft 6. One end of the adjustment frame 33 is fixedly connected to the locking clip 9. The present invention also includes a return spring 34. Multiple return springs 34 are provided. One end of the return spring 34 is fixedly connected to the second end face toothed ring 32, and the other end of the return spring 34 is fixedly connected to the support frame 7. The return spring 34 is in a stretched state.

[0040] Example 3

[0041] like Figures 2-6As shown, this utility model discloses a portable multi-directional training chair. Compared to Embodiment 2, this embodiment further discloses the structure of a limiting mechanism. The limiting mechanism includes a mounting cylinder 41, a limiting block 42, a movable rod 43, and an adjustment assembly. The mounting cylinder 41 is fixedly connected to the support frame 7. One end of the limiting block 42 is slidably disposed within the mounting cylinder 41, and the other end of the limiting block 42 passes through the mounting cylinder 41 and the support frame 7, extending into the support frame 7. One end of the movable rod 43 is fixedly connected to the limiting block 42, and the other end of the movable rod 43 passes through the mounting cylinder 41 and extends into the support frame 7. Externally, an adjustment assembly is mounted on the mounting cylinder 41 for adjusting the movable rod 43, and also includes a pre-tension spring 45. The pre-tension spring 45 is located inside the mounting cylinder 41, with one end connected to the limiting block 42 and the other end fixedly connected to the inner wall of the mounting cylinder 41. The adjustment assembly includes an adjustment rod 441 and an adjustment plate 442. One end of the adjustment rod 441 is rotatably connected to the mounting cylinder 41, and the movable rod 43 has a through-hole 443. The adjustment rod 441 passes through the movable rod 43 through the through-hole 443, and the adjustment plate 442 is fixedly connected to the adjustment rod 441.

[0042] When the chair needs to be fixed in position, step on the locking clip 9. The locking clip 9 rotates and comes into contact with the surface of the traveling wheel 8, locking the traveling wheel 8. When the locking clip 9 locks the traveling wheel 8, the limiting block 42, under the action of the pre-tension spring 45, limits the locking clip 9. The rotation of the locking clip 9 drives the adjusting frame 33 to rotate together. The rotation of the adjusting frame 33 pushes the first end face toothed ring 31 to move upward and engage with the teeth of the first end face toothed ring 31, thereby locking the mounting shaft 6 and preventing the mounting shaft 6 and the support frame 7 from rotating. The position of the chair is further fixed. When the chair needs to be moved, step on the adjustment plate 442 with your foot. The adjustment plate 442 drives the adjustment rod 441 to rotate. The rotation of the adjustment rod 441 drives the limit block 42 to move through the movable rod 43, which causes the locking card 9 to lose its limit. The locking card 9 rotates and disengages from the traveling wheel 8. At the same time, the locking card 9 drives the adjustment frame 33 to move. After the adjustment frame 33 moves, the second end face toothed ring 32 disengages from the first end face toothed ring 31 under the action of the return spring 34. The mounting shaft 6 and the support frame 7 can rotate to facilitate the movement of the chair.

[0043] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
