Description

Technical Field

[0001] The utility model belongs to the technical field of hand rehabilitation training, and specifically relates to a hand rehabilitation training device. Background Art

[0002] Finger strengtheners are usually composed of multiple finger pressing devices and built-in springs. Put your fingers on the finger strengthener and apply pressure to overcome the spring force to exercise your finger strength. Finger strengtheners are suitable for people of all ages, whether they are athletes, fitness enthusiasts, office workers, or patients and the elderly who need hand rehabilitation. They can all use finger strengtheners to train and restore their finger strength.
