Here, through setting up lead screw 8 and shaft coupling 9 to link to each other lead screw 8 with driving motor through shaft coupling 9, simple structure, low cost, and easily realize that drive division 3 orders about foot placing parts 4.
Of course, the driving part 3 in this embodiment may also adopt other linear module structure besides the above structure form, for example, adopt a linear motor, and the foot placing member 4 is slidably disposed on the linear motor through the sliding seat 7.
In the specific structure of this embodiment, the foot placing member 4 includes a foot pedal provided on the sliding seat 7, and a foot locking member provided on the foot pedal. This setting of foot lock piece can fix hemiplegia patient's foot, avoids hemiplegia patient's shank to break away from the running-board, and then promotes the foot and places the safety in utilization of piece 4. It should be noted that the foot lock member may be a conventional hook and loop fastener, which is not shown in the drawings.
In order to adjust the position of the two knee supports 5 in the height direction of the base 1, as shown in fig. 1, 2 and 6, the supporting mechanism includes a height-adjustable longitudinal support 10 disposed on the base 1, and the longitudinal support 10 includes a supporting column 1001 and a supporting rod 1002.
