[0040] A rehabilitation exercise method comprises the following steps: Step 1: Sitting opposite to each other: two patients sit opposite to each other at the two ends of the device body 1; Step 2: Resistance adjustment: The resistance of the exercise push column 6 is adjusted by the electric telescopic rod 18; Step 3: Pushing column 6 for reciprocating lower limb exercise: Two patients use pushing column 6 for reciprocating lower limb exercise to exercise their lower limbs.

[0041] When the patient is exercising the lower limbs, he sits at the two ends of the device body 1 relatively to each other, and then pushes the exercise push column 6 through the lower limbs to achieve the reciprocating motion of the exercise push column 6, thereby achieving the exercise of the lower limbs. At the same time, the speaker 3 can play music, and the counter 2 can count the number of pushes for each patient, thereby increasing a certain degree of competitive interest and improving the patient's exercise enthusiasm. When adjusting the resistance of the exercise push column 6, when it is necessary to adjust it to a larger value, the controller 4 controls the electric telescopic rod 18 to extend and drive the driving bearing plate 5 to move toward the device body 1, so that the first movable support plate 8 is pushed downward under the action of the movable connecting rod 84. As the first movable support plate 8 moves downward, under the restriction of the exercise push column 6, the first connecting spring 873 will be further compressed, so that under the action of the elastic force of the first connecting spring 873, the first force plate 87 will increase the force on the exercise push column 6, and as the first movable support plate 8 moves downward, under the action of the inclined pull frame 86, the movable connection bar 88 will be driven to move, so that the second movable support plate 8 is pushed upward under the action of the articulated connecting rod 885. The support plate 9, under the restriction of the exercise push column 6, will make the second connection spring 96 further compressed, so that the second force plate 93 increases the force on the exercise push column 6, so that the resistance of the exercise push column 6 will become larger when it moves. When it is necessary to adjust the resistance to be smaller, the electric telescopic rod 18 is retracted to drive the driving bearing plate 5 to move in the opposite direction, which is very convenient and can meet different usage requirements. In addition, when it is necessary to disassemble the exercise push column 6, the two movable plug plates 74 on the movable disk 7 are pushed at the same time. , so that the locking block 791 exits the locking slot 65, the movable disk 7 can be removed, and then the exercise push column 6 can be removed. When installing the exercise push column 6, it is inserted into the exercise channel 11, and then the two movable plug plates 74 on the movable disk 7 are pushed toward each other at the same time to plug the connecting plug column 71 into the connecting socket 63. Releasing the movable plug plate 74 can make it reset under the action of the spring piece 78, and then the locking block 791 is plugged into the locking slot 65, thereby realizing the installation of the exercise push column 6. The operation is simple, convenient and quick.
