[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a pulling rod to drive the movable plate and the insert block to move back and forth, pulling the insert block out of the slot. Then, the second support plate is rotated to drive the second connecting plate, the rotating rod, the mounting shell, the spring, the movable plate, the driving rod, and the insert block to rotate. After the second support plate is adjusted to a suitable angle, the driving rod is released. Under the action of the spring force, the movable plate drives the movable plate and the insert block to move back and forth, inserting the insert block back into the slot. The second support plate is positioned by the insert block and the slot.

[0014] 2. This utility model uses the rotation of the threaded rod to drive the threaded plate and the hand support plate to make lateral movement, thereby adjusting the position of the hand support plate.

[0021] Please see Figures 1-5 An adjustable hand rest includes a first support plate 1, with connecting straps 2 installed on both the front and rear sides of the first support plate 1. A bottom buckle 5 is installed on the surface of the connecting straps 2, a neck strap 3 is provided at the top of the connecting straps 2, and a buckle cap 4 is provided on the surface of the neck strap 3. A hand rest plate 9 is provided on the right side of the first support plate 1. A mounting groove 6 is formed at the bottom of the first support plate 1, and an adjustment component 21 is provided inside the mounting groove 6. A first connecting plate 11 is welded to the left side of the first support plate 1, and a rotating rod 14 is rotatably connected to the opposite side of the first connecting plate 11. A slot 12 is formed on the surface of the first connecting plate 11. A mounting shell 15 is welded to the front side of the rotating rod 14, and a second connecting plate 13 is fixedly fitted onto the surface of the rotating rod 14. A spring 16 is welded to the inner wall of the mounting shell 15, a movable plate 17 is welded to the rear side of the spring 16, an insert block 19 is welded to the rear side of the movable plate 17, a driving rod 18 is welded to the front side of the movable plate 17, and a second support plate 20 is welded to the top of the second connecting plate 13.

[0022] Please see Figure 1 and Figure 4 The adjustment component 21 includes a threaded plate 8. By setting the threaded plate 8, it is easy to move the hand support plate 9 and adjust the position of the hand support plate 9. The left side of the threaded plate 8 extends into the inner cavity of the mounting groove 6. A threaded rod 7 is provided through the left side of the threaded plate 8. The right side of the threaded plate 8 is welded to the hand support plate 9. A Velcro strap 10 is installed on the surface of the hand support plate 9.

[0023] Please see Figure 4 and Figure 5 The inner cavity of the mounting groove 6 is welded with a positioning plate. By setting the positioning plate, the threaded rod 7 can be easily positioned and rotated. The surface of the threaded rod 7 is rotatably connected to the positioning plate.

[0024] Please see Figure 4 A friction sleeve is fixedly fitted on the left side of the threaded rod 7. By setting the friction sleeve, it is easy for people to rotate the threaded rod 7 and to move the threaded plate 8. The surface of the threaded rod 7 is threadedly connected to the threaded plate 8.

[0025] Please see Figure 5The bottom of the first support plate 1 is connected to a protective plate by bolts. By setting the protective plate, the threaded rod 7 and threaded plate 8 in the mounting groove 6 can be easily protected, and the threaded rod 7 and threaded plate 8 can be easily operated normally.
