Specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, the present invention is described further:
Refer to Fig. 1-Fig. 4, the present invention relates to a kind of wheel combination device and hand buggy, wherein this wheel combination device include leading
Wheel 30, auxiliary wheel 31, axletree 32 and draw off gear.
Its better embodiment includes axletree 32 and the main wheel 30 being arranged on axletree 32 two ends, also includes at least three
Individual auxiliary wheel 31 and the draw off gear being socketed in axletree 32, described draw off gear includes the sleeve being socketed on axletree 32
10th, the first stopper slot 12 being fixed in main wheel 30 and the second stopper slot 11 being fixed on axletree 32, described sleeve 10
Both sides are respectively equipped with multiple the first buckles 101 for the first stopper slot 12 described in clamping and for clamping the second stopper slot 11
Second buckle 102, described auxiliary wheel 31 is arranged on support bar 20, a hinged draw bar 21 inside described support bar 20, institute
State draw bar 21 other end to be fixed on described sleeve 10, promote sleeve 10 to the first stopper slot 12 or the second stopper slot 11
Making draw bar 21 drive auxiliary wheel 31 is in stretch or gathering activity along axletree 32.
According to one preferred embodiment, described main wheel 30 is provided with a fixed seat 301, for hinged support bar
20.
