The invention provides an elbow joint flexion-extension trainer. The elbow joint flexion-extension trainer comprises a forearm protecting jacket, a flexion-extension switching guiding arm, a support sliding arm, a movement sliding arm, a handle, an extending frame and an upper arm protecting jacket, wherein the forearm protecting jacket is fixed at the first end of the flexion-extension switching guiding arm; the second end of the flexion-extension switching guiding arm is fixed on the support sliding arm; a rack is arranged at the first end of the movement guiding arm, and the support sliding arm is meshed with the rack by virtue of a gear, so that the support sliding arm is fixed on the movement guiding arm; the handle is connected to a central shaft of the gear; the upper arm protecting jacket is fixed on the extending frame; and the extending frame is fixed on a second end of the movement guiding arm. When the elbow joint flexion-extension trainer is used, an upper arm and a forearm are respectively placed in the forearm protecting jacket and the upper arm projecting jacket to be fixed, the gear is driven to rotate on the rack of the movement guiding arm by rotating the handle so as to adjust angles of the support sliding arm and the movement guiding arm, and further adjustment of an elbow joint flexion angle is realized; and the trainer is simple in structure and easy to operate, and a patient does not need professional guidance of a rehabilitation trainer and can purchase personally and train and use the elbow joint flexion-extension trainer at home.
