Further, described sleeve inner is additionally provided with stopping means, and described stopping means is for limiting sliding distance in sleeve for the slide block.
Further, described stopping means is cylinder ring, and described cylinder ring is positioned at the lower section of slide block and can slide up and down along sleeve inner, and described cylinder ring can be by the second adjusting nut regulation relative to the position of sleeve.
Further, described 3rd support bar is connected by spherical pair between described sucker.
The invention has the beneficial effects as follows:
The crutch structure of the present invention is simple, by the length of the first adjusting nut adjustable telescopic rod, thus changes the entire length of crutch, can be suitable for the patient of differing heights;Second, the crutch of the present invention is provided with an elastic device, when patient goes downstairs, when a certain step prepares to march toward next step, under the effect of gravity and spring, the 3rd support bar below slide block forward extends out, and faster touches the next step on stair than traditional crutch, facilitates patient to go downstairs;3rd, the bottom of the 3rd support bar of the crutch of the present invention is equipped with sucker, during crutch contacts to earth, particularly relatively slide ground on walking when, crutch grab ground ability higher, more safe and reliable;4th, the stopping means of the sleeve inner of the crutch of the present invention can adjust sliding distance in sleeve for the slide block, and thus, the present invention is also suitable for the different shoulder height of stair;5th, it is connected by spherical pair between the 3rd support bar and described sucker, sucker can be made to keep forward to contact with ground all the time, grab more firm.

Detailed description of the invention
Purpose, technical scheme and advantage for making the embodiment of the present invention are clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, every other embodiment that those of ordinary skill in the art are obtained under the premise of not making creative work, broadly fall into the scope of protection of the invention.
The present invention will be further described with specific embodiment below in conjunction with the accompanying drawings:
First it is noted that upper and lower, left and right described in present embodiment etc. are consistent with the upper and lower, left and right described in accompanying drawing etc., but it is not intended that limitation of the invention further.
The crutch described in embodiment of the present invention as shown in Figures 1 and 2, including the first support bar the 11st, the second support bar 12, first support bar 11 is connected by V-type connecting rod 2 with the lower section of the second support bar 12, is provided with wooden block 3 and handrail 4 between the first support bar 11 and the second support bar 12;The lower section connection expansion link 5 of V-type connecting rod 2, one end that expansion link 5 is connected with V-type connecting rod 2 maintains static, the other end can stretch up and down relative to fixed one end, the stroke of expansion link 5 can be regulated by the first adjusting nut 61, i.e. unclamps the first adjusting nut 61, and expansion link 5 telescopic movable is unrestricted, after telescopic location regulation is appropriate, tighten the first adjusting nut 61, the length of expansion link 5 can be fixed, thus regulate the length of whole crutch;The lower section of expansion link 5 is connected with sleeve 7, upper cartridge is connected with the scalable position of expansion link 5, sleeve 7 inner hollow, and lower end has opening, the part of sleeve 7 inner hollow is provided with spring 15, spring 15 one end is connected with the top of sleeve 7, the other end of spring 15 is connected with slide block 10, slide block 10 can slide up and down inside sleeve 7, it should be noted that, in order to ensure that the present invention realizes its function smoothly, in the whole stroke that slide block 10 slides, spring 15 should be in compressive state all the time, with ensure whole during there is the existence of elastic restoring force all the time;Being connected with the 3rd support bar 13 below slide block 10, the bottom of the 3rd support bar 13 moves up and down equipped with sucker 8, the movement that slide block 10 followed by the 3rd support bar 13 and sucker 8.
