The springs 10 are installed at both ends between the pull plate 18 and the interior of the housing 9. The damper 11 is provided inside the spring 10. The bottom end of the pull plate 18 is sleeved with a protective sleeve 19. The bottom end of the housing 9 is provided with a limiting groove 20. The bottom end of the support rod 8 is fixedly connected to the mounting plate 17. Adjustment holes 16 are respectively provided on both sides of the interior of the mounting plate 17 and on the left sides of the front and rear ends of the interior of the support plate 2. Mounting bolts 21 are provided inside the adjustment holes 16.

[0027] The pull plate 18 passes through the interior of the limiting groove 20 and slides inside the limiting groove 20. There are multiple groups of adjustment holes 16, which are evenly spaced on the left sides of the front and rear ends of the support plate 2. The mounting plate 17 is fixed through the adjustment holes 16 and the mounting bolts 21.

[0028] Specifically, if Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, when the position of the shell 9 needs to be adjusted, the mounting bolt 21 is unscrewed from the inside of the adjustment hole 16 to make the mounting plate 17 lose its fixation. After the mounting plate 17 loses its fixation, the mounting plate 17 can be slid to adjust the position of the shell 9. After adjustment, the mounting bolt 21 is screwed into the inside of the adjustment hole 16 again to fix the mounting plate 17. When exercise is needed, grab the pull plate 18 to move the pull plate 18 closer to the middle of the active wrist joint to promote blood circulation in the fingers and wrist, and prevent arteriovenous blood blockage caused by arm inactivity after surgery. The damper 11 can improve the stability of the spring 10.

[0029] Embodiment 2: A non-slip pad 3 is provided at the bottom end of the base plate 1, and a mounting block 4 is fixedly connected to the top end of the non-slip pad 3. A mounting groove is provided at the bottom end of the interior of the base plate 1, and the mounting block 4 is embedded in the interior of the mounting groove.
