The specific embodiment
For to structure of the present utility model, technical characterictic and effect thereof, can have and further understand and be familiar with, lift a preferred embodiment now, and conjunction with figs. is described in detail as follows:
Referring to shown in Figure 2, a kind of crutch, roughly identical with known crutch, mainly comprise: top is two tubular bodies, 11, two tubular bodies, 11 upper ends of expanding shape and is installed with the soft shoulder 12 of holding up, and the lower end merges and is connected a footmuff 13; Each tubular body 11 epimere is respectively equipped with corresponding several spacing hole 111, one levers 2 two ends difference plug-in card in the corresponding spacing hole 111 of two tubular bodies 11, and is fastened between two tubular bodies, 11 epimeres.
Referring to shown in Figure 3, major technique of the present utility model is characterised in that: this lever 2 comprises a main body 21 and the flexible member 22, protruding pin 23, hook bar 24, the limit element 25 that are provided with in pairs; Wherein:
These main body 21 two ends are provided with trepanning 211, trepanning 211 wears for tubular body 11, corresponding trepanning 211 places, these main body 21 two ends are provided with a translot 212 that connects mutually respectively, flexible member 22, protruding pin 23 are housed in the translot 212 in regular turn, and on the inside and outside wall of translot 212, are respectively equipped with elongated hole slot 213 and track 214; These hook bar 24 locating slips are in respective track 214, and in addition, these main body 21 excircles are provided with concavo-convex alternate anti-skidding 215, in case hand skids when gripping.
Each flexible member 22 is placed in the translot 212 of main body 21; A protruding pin 23 is inserted in the corresponding translot 212 again, is equipped with recess 231 on each protruding pin 23, be provided with a fore-set 232 with respect to the end of tubular body 11, fore-set 232 can be with the displacement of protruding pin 23, inlay card or break away from the corresponding spacing hole 111 of tubular body 11.
Each hook bar 24 is placed in the track 214 of main body 21, and the two ends of hook bar 24 are respectively equipped with and protruding pin 23, limit element 25 corresponding hook portions 241.
Each limit element 25 sliding sleeve is in main body 21 outsides, and hook portion 241 places that each limit element 25 correspondence is positioned at the hook bar 24 of main body 21 elongated hole slots 213 are provided with corresponding shrinkage pool 251.
Shown in Fig. 4,5, when lever 2 is assembled with two tubular bodies 11 of crutch 1, each component sets with lever 2 is integrated earlier, soon each flexible member 22, protruding pin 23 are inserted in the corresponding translot 212 in main body 21 two ends in regular turn, again each hook bar 24 is distinguished eye-splices in respective track 214, the hook portion 241 of one end is snapped in the recess 231 of protruding pin 23, again with each limit element 25 respectively sliding sleeves then the hook portion 241 of hook bar 24 other ends is snapped in location in the shrinkage pool 251 of limit element 25 in main body 21 outsides.When desire is assembled in lever 2 on two tubular bodies 11, earlier limit element 25 is pulled outward and drawn, two corresponding protruding pins 23 are contracted in the corresponding translot 212 (as shown in Figure 5) simultaneously, at this moment, two tubular bodies 11 are placed in the trepanning 211 at main body 21 two ends, make the fore-set 232 of each protruding pin 23 end aim at spacing hole 111 on two tubular bodies 11, decontrol each limit element 25, under the effect of each flexible member 22, each limit element 25, protruding pin 23 reset, and the fore-set 232 of each protruding pin 23 end just can be intercalated in the spacing hole 111 interior lockings of two tubular bodies 11 respectively.
