Dynamic space prevents fixed curvature for a long time and leads to knee contracture, and can prevent leg hyper-extended, prevents injured ankle
Joint, which contacts to earth or collides with, causes secondary damage；
Four, people's leg stretches into shell (4), and shell (4) upper and lower part corresponds to human thigh and lower leg portion respectively, then uses Buddhist nun
Imperial hasp (5) is fixed by leg and shell (4), this sprained ankle patient walk helper can provide support, substitute knee joint with
The work of lower leg, while there are three supporting points with ground for two bending supporting legs (12) and one long allotment leg (14), support can
It leans on, hold handle (9) with the hand of the opposite side of patient injury's leg provides balance for upper body；
Five, locking counterbore (16) is two, two locking counterbores (16) respectively in bearing (18) both sides, two locking counterbores (16) with
Bearing (18) on the same line, locks counterbore (16) interior fixed magnet (15), and magnet (15) prevents locking level (17) from falling, and locks
Determine cooperation locking level (17) in counterbore (16), locking level (17) is irony, setting locking through-hole (28), locking level on chassis (11)
(17) cooperation is in locking through-hole (28), locking level (17) is passed through stretch into after lock hole locking counterbore (16) and with magnet (15)
It is attracted, locking level (17) fixes height adjustment disk (10) and the relative position of chassis (11) at this time；If it is another one leg
Ankle injury pulls up locking level (17), rotation height adjustment disk (10) 180 degree, at this time another locking counterbore (16) and locking
Through-hole (28) coaxially, then reinserts locking level (17) and stretches into locking counterbore (16) and magnet (15) actuation, still at this time
It is to hold handle (9) with the hand of the opposite side of patient injury's leg to provide balance for upper body, can be thus directed to left and right leg and carry out
Switching, it is of low cost without developing two sets of walk helpers, and clever structure specifically for left and right leg；
Six, when not used, folding bolt (25) is unscrewed so that it is heavy that folding bolt (25) is detached from the folding folded in adjusting set (26)
Hole (24) will fold adjusting rod (23) and extract out, then folds bending supporting leg (12) with folding landing leg, chassis (11) are lifted
It rises and folds, greatly save storage space.
