Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. 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.

1-3, the present utility model provides a technical solution: an upper limb exercise device for sports training, comprising a first handle 1, a first spring 11 and a second spring 12, and one end of the first handle 1 is provided with a spring Mounting hole 8, one end of the first spring 11 is fixedly connected with a connecting block 10, one end of the connecting block 10 is fixedly connected with a threaded head 9 with an external thread, one end of the threaded head 9 is threadedly connected with the spring mounting hole 8, and the second spring The middle part of 12 is movably connected with a rubber cord 13, the second spring 12 is threadedly connected with the first handle 1 and one end of the rubber cord 13 is fixedly connected with the first handle 1, and one side of the first handle 1 passes through the first spring 11 is fixedly connected with the second handle 2 , and one side of the first handle 1 is fixedly connected with the second handle 2 through a second spring 12 .

In actual implementation: one end of the first handle 1 is provided with a concave-convex structure 3, and the outside of the concave-convex structure 3 is glued with a non-slip rubber pad 4, which is convenient for holding the tensioner for stretching, and the interior of the first handle 1 is fixedly connected with a spare block 6. One end of the spare block 6 is provided with a spare mounting hole 7 that is the same as the spring mounting hole 8.
