Specific embodiment:

The explanation for example to the design below in conjunction with the accompanying drawings.

As shown in Figure 1 and Figure 2, the crutch of the design comprises handle 2, pole 3, leg 4, and described pole 3 is at it near lower end Tube wall border on uniformly have several rectangles leg mouth 8 it is illustrated that citing in be three or four, in leg On mouthfuls 8 direction towards pole axle center, all devices have that one same, the axis direction arcuation to pole is processed in interior outer end The leg 4 of warpage, shape as shown in Fig. 2 Fig. 3, being connected to of the inner end of leg 4 all activities one is in leg oral area in pole 3 tube chamber Position round slider 10 on, the diameter of slide block 10 is slightly less than the internal diameter of pole tube chamber, it can smoothly in tube chamber on move down Dynamic do not seem that space falls again, leg and the leg that the flexible connection position of slide block is on the slider side wall corresponding with leg inner end Axle 7, as in Fig. 2 left side zoomed-in view and right side under enlarged drawing shown in, such connected mode can obtain following operation Effect: when slide block 10 rises or moves down, outwards distributing, by leg mouth, the foot portion stretching out will be in leg axle and leg Rotate downwards so that whole leg is in the vertical closing up or locates upwards about going to almost horizontal shape under the collective effect of mouth In four bulk, under this kind of function mode, for each leg mouth leg similarly relatively in the inner be one promote itself or on Or under the force fulcrum that rotates general；The bottom being threaded with a bottle cap shape in the lower end of pole 3 blocks up 5, blocks up 5 and slide block 10 bottom of at Between nervous install a spiral helicine compression spring 6, the inner tubal wall border of the pole 3 above slide block 10 sets meanwhile It is equipped with the block 9 of several square, it can limit downwards the upper shifting movement of slide block, be the top dead centre of slide block；Court in handle 2 On tube wall on from just starting to the position in pole axle center to push away torsion groove 12 to what one end of handle was machined with one notch-like, such as scheme Shown in 2, the pushing away an of arcuation is turned round 1 and is turned round connecting rod 13 with a round bar shape in groove just submerging in its lower end to the position in pole axle center to push away Upper end be flexibly connected by a pin rod 14, a shaft-like core bar 11 be fixed in above the intraluminal slide block 10 of pole 3 and to Upper one is flexibly connected also by bearing pin 14 with the lower end of connecting rod 13 through to after the position under pole upper end, as shown in Figure 2 and its In right side on shown in enlarged drawing, when push away turn round 1 along push away torsion groove 12 to front or rear slip when, it can drive connecting rod 13 under it, core Bar 11 simultaneously and then moves or lower shifting movement on drive slide block 10 work bottom, finally leg is produced with recovery and closes up uprightly or discharge Two kinds of regulating effects of level of scattering, are become by such as Fig. 2 shape and turn to such as Fig. 3 shape or turned to as Fig. 2 shape by the change of such as Fig. 3 shape；Core bar 11 directly up with push away turn round 1 is connected be not provided with connecting rod 13 when, because limited by pole caliber push away turn round edge push away torsion groove 12 regulation and control slide Move and can be blocked and seem not smooth, additional the preceding paragraph connecting rod, to connect, solves this problem, shape as shown in Figure 3；Bullet Spring 6 and bottom block up 5 match can all the time slide block 10 be produced one upper move power-assisted, for mitigate the control manipulation resistance pushing away torsion and Leg closes up the stable of the determination state of its position rear very necessary positive effect, simultaneously under this kind of state, slide block Upper limb face can just touch block 9 and is engaged by it, and this locking of block acts on the leg one that also can be closed up Support power-assisted, when leg be in four scatter the self-support standing state coming when spring and bottom block up and equally also can give its strong Support；The shape (Fig. 3 shape) that leg 4 is arranged to the axis direction arcuation warpage to pole for the interior outer end is mainly to adapt to pole and cunning The setting of block, compound mode, the two ends of arcuation can better meet to support oneself stands and closes up the regulating effect of support, at leg In as shown in Figure 3 when closing up holding state, it supports the support force of body can make because of the arcuation feature of the lower end of its arcuation The transmission of support force centripetal direction, otherwise, such as select full straight-bar shape its under the effect of the pressure can the transmission of unfavourable direction, This is unfavorable for the stability of total stress and reliability of operation aspect, so, the arcuation design of the design is no It is suspected to be necessary.When specifically used, taking the state of Fig. 3 as a example, now it is in closing up the use state of support, pushes away torsion and be in handle One end of handss, stopping when stopping needs both hands to do during other things then to push away torsion with moving slip after the thumb of the handss grasping handle, such as front Described, associated each assembly can promote leg four to dissipate separately, be regulated to Fig. 2 shape by Fig. 3 shape, be also that Fig. 4 shape is regulated to Fig. 1 Shape, four legs dissipating can give crutch an overall reliable and stable self-support standing support, simultaneously also it is seen that crutch whole The body weight heart can be transformed into almost horizontal shape because of leg by vertical type, objectively also reduce center of gravity and be more beneficial for what its self-support was stood Stable, when needing to walk on mobile then more reversely before push away torsion so that leg is returned to original state again, support can be met again The job demand of walking.The design is simple to operation, and one hand can be using so that the necessary use of this elderly population of crutch Tool obtains brand-new use function, eliminates the danger tripped, has a kind of highly beneficial improvement.
