251 when rotating, second sleeve 253 along the and screw rod moves up and down.The stick stem when not in use, can unclamp the second self-locking in crutch
During structure 25 entirely inserts lower stick stem 23 in stick stem 22, then unclamp the first self-locking structure 24 and middle stick stem 22 is entirely inserted to upper cane
In bar 21, so whole crutch just becomes to hold very much, is easy to old man to carry, when needing to use crutch, extract lower stick stem 23 with
Middle stick stem 22 to correct position and then the first self-locking structure 24 and the second self-locking structure 25 will be tightened so that by upper stick stem 21, in
Stick stem 22, lower stick stem 23 are fixed together, and the operation principle of first self-locking structure 24 is as follows：Middle stick stem 22 is inserted into upper cane
After bar 21, stick stem 22 in rotation, because lower end and the middle stick stem 22 of the first screw rod 241 are fixed together, middle stick stem 22 rotates meeting
The first screw rod 241 is driven to rotate, the first screw rod 241 can cause the first sleeve 243 to be moved up and down along the first screw rod 241 when rotating,
Because the external diameter of the first swollen cylinder 244 and the internal diameter of upper stick stem 21 match and between the first swollen cylinder 244 and the inwall of upper stick stem 21
Frictional fit, when the first sleeve 243 moves up, the first swollen cylinder 244 is because frictional force presence can't move up, simultaneously
Due to the internal diameter of the first swollen cylinder 244 taper into from bottom to top and the external diameter of the first sleeve 243 be less than the first swollen cylinder 244 lower end
Internal diameter and the upper-end inner diameter for being more than the first swollen cylinder 244, the upper end of the first swollen cylinder 244 can be supportted when the first sleeve 243 moves up
Open so that swelling between the first swollen cylinder 244 and the inwall of upper stick stem 21, so as to complete auto-lock process, to unblock, only need reverse
Stick stem 22 in rotation, whole process operation it is very simple, be easy to old man to be operated, and old man can according to oneself
Height freely adjusts the length of its crutch, without deliberately being bought according to height, to people use and purchase is brought
Very big facility.The operation principle of second self-locking structure 25 is identical with the operation principle of the first self-locking structure 24.
Crutch can produce an impulsive force when landing suddenly, the impulsive force can cause certain damage to the bone of the elderly
Wound, in order to avoid the impulsive force causes to damage to the elderly, protects the bone of the elderly, the upper end and second of the lower stick stem 23
Buffer unit 26 is provided between self-locking structure 25, the buffer unit 26 includes inserted link 261, ring baffle 262, circular baffle plate
263rd, spring 264, the external diameter of the circular baffle plate 263 and the internal diameter of middle stick stem 22 are mutually matched, and the upper end of the inserted link 261 is consolidated
The lower surface of circular baffle plate 263 is scheduled on, the ring baffle 262 is fixed on the upper end of lower stick stem 23, and the spring 264 is set in
On the inserted link 261 and lower end of inserted link 261 is stretched into lower stick stem 23 through ring baffle 262, the internal diameter of the ring baffle 262 with
The external diameter of inserted link 261 is adapted.By setting buffer unit 26, profit between the upper end of lower stick stem 23 and the second self-locking structure 25
Crutch can be offset with buffer unit 26 to land suddenly caused impulsive force, so as to avoid the impulsive force from causing to damage to the elderly
Wound, protect the bone of the elderly.
In order to further offset impulsive force when crutch lands, so as to avoid the impulsive force from causing to damage to the elderly, protect
The bone of the elderly is protected, the lower end of the lower stick stem 23 is provided with anti-collision structure 8, and the anti-collision structure 8 includes movable block
801st, fixed dam 802, sideboard 803, the lower end of the movable block 801 are connected with cane point 5 or cane first 6, movable block 801
Upper end is stretched into lower stick stem 23 and can be in lower stick stem 23 slidably, the fixed dam 802,803 equal position of sideboard
In in lower stick stem 23, the fixed dam 802 is fixed on the inwall of lower stick stem 23, and sideboard 803 can be along lower stick stem 23
Central axial direction slidably, sideboard 803, the inwall of fixed dam 802 and lower stick stem 23 surround one it is closed
Cavity 804, is provided with breather cheek valve 805 on the fixed dam 802, the air inlet of the breather cheek valve 805 with it is extraneous
Connection, the gas outlet of the breather cheek valve 805 connects with cavity 804, the sideboard 803 be located at sideboard 803 and
Between movable block 801, rubber spring 806, the rubber spring 806 are provided between the sideboard 803 and movable block 801
Lower end be fixed on the upper surface of movable block 801, the upper end of rubber spring 806 is fixed on the lower surface of sideboard 803.This is anti-
The operation principle of impact structure 8 is as described below：When the cane of crutch first 6 or cane point 5 land, the impact of a moment can be produced
Power, the impulsive force pass to movable block 801 along cane point 5 or cane first 6 and cause movable block 801 along the upward sliding in lower stick stem 23,
The meeting compression rubber spring 806 during moving up of movable block 801, the rubber spring 806 compressed can be to movable blocks 801
One downward reaction force offsets part of impact force, while gives 803 1 upward thrusts of sideboard so that sideboard
803 is movable upwards along the central axial direction of lower stick stem 23, due in sideboard 803, fixed dam 802 and lower stick stem 23
Wall surrounds a closed cavity 804, and when sideboard 803 moves up, cavity 804 tapers into, the sky in cavity 804
Gas is compressed, and sideboard 803 is by the resistance of compressed air, and so far the cane of crutch first 6 or cane point 5 land caused moment
Impulsive force is cancelled, and will not be delivered to handle along stick stem 2, it is possible to prevente effectively from the impulsive force causes to damage to the elderly, protection
The bone of the elderly, it is to cause sideboard in order to avoid the air in cavity 804 is very few to be provided with breather cheek valve 805
803 distances moved up are excessive, so as to influence the normal use of crutch, if the air in cavity 804 is very few, only need to hold cane
First 6 or cane point 5 pulls out so that sideboard 803 moves down, such cavity 804 becomes larger, the gas in its cavity 804
Pressure tapers into, and outside air can be smoothly to enter in cavity along breather cheek valve 805, and ensure that has in cavity 804
Enough air.
