Wherein, locking mechanical system 780 includes support column 781, roll wheel 783 and keep off board 785, support column 781 is connected with second splint 750's bottom, holding tank 7811 has been seted up to support column 781, be provided with electro-magnet 7813 and spring 7815 in the holding tank 7811, the one end of spring 7815 is fixed in support column 781, the other end of spring 7815 is connected with keep off board 785, roll wheel 783 rotates with support column 781 to be connected, keep off board 785 can rotate with the restriction roll wheel 783 butt when electro-magnet 7813 cuts off the power supply, keep away from roll wheel 783 when electro-magnet 7813 switches on to keep off board 785.

In use, the damper plate 785 can be electrically controlled to contact the roller wheel 783 by controlling the on/off of the electromagnet 7813, thereby braking or rolling the roller wheel 783. When the lower limb trainer 700 needs to be moved, the electromagnet 7813 is electrified, at the moment, the electromagnet 7813 generates suction to the baffle 785, the spring 7815 is compressed, and the baffle 785 is separated from the rolling wheel 783 to realize rolling. When the electromagnet 7813 is powered off, the baffle 785 is abutted against the rolling wheel 783, and braking is achieved. The locking mechanism 780 improves the mobility of the lower limb exerciser 700 so that the lower limb exerciser 700 can be easily moved, and also improves the mobility of the limb rehabilitation exerciser 10.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
