[0033] As a technical optimization solution of the present invention, due to the provision of the spring 21 , a good elastic recovery effect can be achieved on the fixing rod 19 .

[0034] refer to Figure 2 A rectangular groove 22 is formed on the top of the bottom plate 1 and is located directly below the double-threaded lead screw 6 . A rectangular block 23 located inside the rectangular groove 22 is fixedly connected to the bottom of the sleeve block 7 .

[0035] As a technical optimization solution of the present invention, due to the arrangement of the rectangular groove 22 and the rectangular block 23, the movement of the two sleeve blocks 7 can be made more stable.

[0036] The working principle and use process of this utility model:

[0037] When the height of the long rod 11 needs to be adjusted, the operator starts the driving motor 5 to rotate the double-threaded screw 6. The rotation of the double-threaded screw 6 drives the two sleeve blocks 7 to move toward each other along the outer surface of the double-threaded screw 6, and then drives the lifting plate 9 and the movable block 3 as a whole to move upward along the inner surface of the movable groove 10 through the hinge rod 8, thereby increasing the height of the long rod 11 to meet the use of people with taller heights.

[0038] When the operator needs to relax the leg muscles, the operator pulls the pull block 20 to make the fixing rod 19 disengage from the inside of the second fixing plate 14, thereby releasing the fixing effect on the clamping block 18, and then rotates the clamping block 18 to make the clamping block 18 disengage from the outer surface of the round rod 16, thereby releasing the fixing effect on the entire rolling block 12. The operator then places the leg on the rolling block 12 and rolls it back and forth to relax.
