Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

1-5, the present invention provides a technical solution: a stretching device for arm training, comprising a vertical cylinder 1, an extension block 2, a cushion block 3 and an adjustment mechanism 4, and the extension block 2 is fixedly installed on the On one side of the vertical cylinder 1, the cushion block 3 is fixedly installed between the inner walls on both sides of the vertical cylinder 1, and the adjustment mechanism 4 is installed in the vertical cylinder 1;

The adjustment mechanism 4 includes two bar-shaped blocks 5 which are respectively fixedly connected with the inner walls of the vertical cylinder 1 on both sides. Rod 7, the bottom ends of the two hinge rods 7 are fixedly installed with the same connecting block 8, the top of the connecting block 8 is fixedly installed with a placing rod 9, and two pressing blocks 10 are sleeved on the placing rod 9, and the moving rod 6 rotates A gear 11 is installed, a rack 12 is fixedly installed on one inner wall of the vertical cylinder 1, the rack 12 is matched with the gear 11, and a pulling rope 13 is fixedly bound on the moving rod 6, and the pulling rope 13 is far away from the moving rod 6. One end extends to the outside of the extension block 2 through the vertical cylinder 1, and one end of the pull rope 13 is fixedly installed with a grip ring 14;

The sides of the two bar blocks 5 that are close to each other are provided with sliding grooves, the same round rod is fixedly installed between the top and bottom inner walls of the sliding groove, and the moving rod 6 is slidably connected with the two round rods. A rope hole is opened on the side of the cylinder 1 close to the extension block 2, and the pull rope 13 is slidably connected in the rope hole.
