There is a detachable baffle 6521 connected to the sliding seat 65, and the baffle 6521 is used to block the sliding seat 66.

When it is necessary to use this device, first sit on the seat 2 and step on the footrest 44, and then step on the footrest 44 for training. During the training process, the training wheels are driven by the sprocket transmission group 40. 41 rotates. When the training wheel 41 rotates, it drives the reciprocating screw rod 64 to rotate through the reduction group 61, the rotating shaft 62 and the bevel gear 63. When the reciprocating screw rod 64 rotates, it drives the sliding base 66 to reciprocate left and right. When the sliding base 66 moves to When blocked by the baffle 6521, the sliding seat 66 is restricted by the baffle 6521 and cannot move. At this time, the footrest 44 cannot be stepped on either. At this time, the patient has also been trained for a period of time and can take a rest or stop training. When it is necessary to train again, the rotating transmission screw rod 651 drives the limiting frame 652 and the baffle 6521 to move to the left until the sliding seat 66 is no longer blocked. At this time, the foot pedal can be continued for training, and at this time the sliding seat 66 It will first move to the left to the leftmost end of the reciprocating screw rod 64 and then move to the right along the reciprocating screw rod 64 until it is blocked by the baffle 6521 again. Then the transmission screw rod 651 can be rotated to control the baffle 6521 to move to the right to perform training again, thus It has the effect of controlling the training time. When contact control is required, the baffle 6521 can be removed. During training, if the friction needs to be increased, the screw 52 can be twisted to control the threaded sleeve 551 and the guide sleeve 552 to move downward. Close to the shaft sleeve 42, the length of the moment arm is reduced, and there is friction between the damping sleeve 53 and the shaft sleeve 42, thereby increasing the force required when pedaling, achieving the effect of increasing training intensity, and after increasing, When pedaling, the friction force will not suddenly decrease or reduce, thereby reducing the force change range to ensure the training effect. When there is no need to increase the friction force, the bolt can also be twisted to separate the thread sleeve 551 and the guide sleeve 552.
