A first threaded rod 6 is movably connected inside the columnar groove 7. The first threaded rod 6 is threadedly connected to a first thread groove 8. The first thread groove 8 communicates with the cavity 2. It further includes:

[0032] The extension and contraction component 9, the sides of the two support plates 1 are respectively fixedly connected with an extension plate 1 901 and an extension plate 2 902, and the square cavity 903 reserved inside the extension plate 1 901 and the extension plate 2 902 is movably connected, the inner wall of the square cavity 903 is rotatably connected with a threaded rod 2 904, and the threaded rod 2 904 is threadedly connected with a threaded groove 2 905 reserved inside the extension plate 1 901, and the outer ring of the threaded rod 2 904 is fixedly sleeved with a shift block 906, and the shift block 906 passes through the notch 907 reserved inside the extension plate 2 902, and the shift block 906 drives the rotation of the threaded rod 2 904 to move the position of the extension plate 1 901 threadedly connected with the threaded rod 2 904, thereby adjusting the gap between the two support plates 1, so that the exercise device is convenient for adapting to lower limbs of different thicknesses;

[0033] A stable installation component 10 is provided with an annular groove 101 inside the threaded rod 6, and an annular block 102 is rotatably connected inside the annular groove 101, and a movable groove 103 is preset inside the annular block 102, and a movable rod 104 is slidably connected inside the movable groove 103, and the end of the movable rod 104 is fixedly connected to a limiting block 105, and the limiting block 105 is movably connected to a limiting groove 106 reserved inside the roller shaft 4, and the limiting groove 106 is communicated with the columnar groove 7, which is convenient for the removal and installation of the foam roller 3.

[0034] Both support plates 1 are arc-shaped, and the two support plates 1 are symmetrically arranged on the left and right, and three groups of foam rollers 3 arranged to fit the arc of the support plate 1 are rotatably connected in the cavity 2 reserved inside each support plate 1, so that the foam rollers 3 on both sides fit the lower limb muscles, which facilitates the rotation of the foam rollers 3 to relax the lower limb muscles.

[0035] The upper part of the threaded rod 6 is provided with threads, and the lower part of the threaded rod 6 is a smooth rod, and the outer wall of the threaded rod 6 is in contact with the inner wall of the columnar groove 7 to realize an up and down sliding connection, thereby ensuring the stability of the threaded connection between the threaded rod 6 and the support plate 1, and at the same time ensuring that the firmness of the connection between the threaded rod 6 and the support plate 1 is not affected when the roller shaft 4 rotates.

[0036] The extension plate 901 is in a horizontal "T" shape, and the outer wall of the T-shaped end of the extension plate 901 is in contact with the inner wall of the square cavity 903 to achieve a sliding connection. The T-shaped end of the extension plate 901 is always located inside the square cavity 903, ensuring that the extension plate 901 and the extension plate 2 902 are installed without falling off, and ensuring that the two support plates 1 are installed without falling off.

[0037] The movable rod 104 presents a horizontal "T" shape. Two movable rods 104, which are symmetrically arranged with respect to the central axis of the annular block 102, are slidably connected in the annular movable groove 103 reserved inside the annular block 102. The outer wall of the movable rod 104 is in contact with the inner wall of the movable groove 103 to achieve a sliding connection, which ensures that the sliding connection between the movable rod 104 and the annular block 102 does not fall off and ensures the stability of the sliding connection between the movable rod 104 and the annular block 102.

[0038] One end wall of the limiting block 105 fixedly connected to the movable rod 104 presents an arc shape. This end wall is in contact with the outer wall of the annular block 102 to achieve a sliding connection. The end of the limiting block 105 far from the movable rod 104 presents a square shape. The outer wall of this end is in contact with the inner wall of the limiting groove 106 to achieve a sliding connection. The limiting block 105 that is slidably connected up and down with the limiting groove 106 inside the roller shaft 4 is rotatably connected to the first threaded rod 6. In this way, when the roller shaft 4 rotates, it will not drive the rotation of the first threaded rod 6, and further the threaded connection between the first threaded rod 6 and the support plate 1 is not affected by the rotation of the foam roller 3.

[0039] The upper end of the limiting groove 106 is closed. The limiting block 105 movably connected inside the first threaded rod 6 is slidably connected in the limiting groove 106 reserved inside the roller shaft 4. This ensures the anti-disconnection connection between the first threaded rod 6 and the roller shaft 4 and facilitates the subsequent installation of the new foam roller 3.

[0040] Working principle: When using a lower limb exercise device for orthopedic care, first, when it is necessary to adjust the gap size between the two support plates 1, turn the dial 906. The dial 906 drives the rotation of the second threaded rod 904 fixedly inserted in the inner circle of the dial 906. The second threaded rod 904 is in threaded connection with the second threaded groove 905 reserved inside the first extension plate 901. In this way, when the second threaded rod 904 rotates, under the limiting effect of the square cavity 903 on the first extension plate 901, the first extension plate 901 moves inside the square cavity 903, and then drives the movement of one side support plate 1 fixedly connected to the first extension plate 901. In this way, the gap size between the two support plates 1 is adjusted. Continuously turn the dial 906 until the foam roller 3 is felt to fit the leg muscles during the movement of the two support plates 1 and then stop. At this time, connect the power supply. The gasket embedded at the lower end of the roller shaft 4 is electrically connected to the inside of the mounting groove 5, and then drives the rotation of the foam roller 3 to perform rolling relaxation exercise on the patient's leg muscles. At the same time, when the roller shaft 4 rotates, the limiting block 105 that is slidably connected up and down with the limiting groove 106 inside the roller shaft 4 is rotatably connected to the first threaded rod 6. In this way, when the roller shaft 4 rotates, it will not drive the rotation of the first threaded rod 6, and further the threaded connection between the first threaded rod 6 and the support plate 1 is not affected by the rotation of the foam roller 3;

[0041] When it is necessary to disassemble and assemble the foam roller 3, twist the rotation of the threaded rod 6. The threaded rod 6 that is threadedly connected to the support plate 1 gradually leaves the inside of the preset thread groove 8 during the rotation process. In this way, the foam roller 3 can be disassembled and replaced. At the same time, the limiting block 105 movably connected inside the threaded rod 6 is slidably connected to the limiting groove 106 reserved inside the roller shaft 4, which ensures the anti-disconnection connection between the threaded rod 6 and the roller shaft 4 and facilitates the installation of the subsequent new foam roller 3.

[0042] Only some exemplary embodiments of the present invention have been described by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
