Plate 802 surrounds an airtight cavity 804, when sideboard 803 moves up, cavity 804 with the inwall of lower stick stem 23
Tapering into, the air in cavity 804 is compressed, sideboard 803 by compressed-air actuated resistance, the so far cane head of crutch
6 or the instant impact that produces when landing of cane point 5 be cancelled, handle will not be delivered to along stick stem 2, this punching can be prevented effectively from
Old people is caused damage by power of hitting, and the skeleton of protection old people, being provided with breather cheek valve 805 is in order to avoid cavity 804
The interior very few distance causing sideboard 803 to move up of air is excessive, thus affects the normal use of crutch, if cavity 804
Interior air is very few, only need to hold cane head 6 or cane point 5 pulls out so that sideboard 803 moves down, such cavity 804
Becoming larger, the air pressure in its cavity 804 tapers into, and outside air just can enter into sky along breather cheek valve 805 smoothly
Intracavity, it is ensured that there is in cavity 804 enough air.
