The structures and working principles of the first little finger rehabilitation trainer 112, the first ring finger rehabilitation trainer 113, the first middle finger rehabilitation trainer 114, the first index finger rehabilitation trainer 115, and the first thumb rehabilitation trainer 116 are the existing technology, which are deformed by gas, and drive the human fingers to complete grasping training, finger separation training, finger pairing training, and thumb extension training through the first glove 111.

[0060] Specifically, in the exemplary embodiment, the first thumb rehabilitation trainer 116 includes a metacarpal support seat 1161, a first knuckle drive seat 1162, a third knuckle drive seat 1164, a second knuckle drive seat 1163, an outer guide tube 1165, an inner guide tube 1166, a ball, an air inlet nozzle, a first air duct, a first bellows 1167, a fixing seat 1168, a second bellows 1169, and a second air duct. A slide groove is provided on the top surface of the metacarpal support seat 1161. The first knuckle drive seat 1162 is rotatably disposed at one end of the metacarpal support seat 1161. The second knuckle drive seat 1163 is rotatably disposed at one end of the first knuckle drive seat 1162 away from the metacarpal support seat 1161. The third knuckle drive seat 1164 is rotatably disposed at one end of the second knuckle drive seat 1163 away from the first knuckle drive seat 1162. The outer guide tube 1165 is an arc-shaped hollow structure, which is installed on the metacarpal support seat 1161. The inner guide tube 1166 is an arc-shaped structure, one end of which is inserted into the outer guide tube 1165, and the other end is connected to one side of the first knuckle drive seat 1162, and can extend a preset length outside the outer guide tube 1165. The ball is fixedly installed at the bottom of the inner guide tube 1166 and can slide along the slide groove. The slide groove can guide the movement of the ball, thereby effectively improving the smoothness of the movement of the inner guide tube 1166. The air inlet nozzle is arranged at one end of the outer guide tube 1165 away from the inner guide tube 1166. The first air guide pipe is connected to the air inlet nozzle. One end of the first corrugated tube 1167 is fixedly connected to the first knuckle drive seat 1162.
