Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail, but not as to restriction of the present utility model.

As shown in Fig. 1 ~ Fig. 7, a kind of dual-purpose bicycle of the utility model, comprising:

One front truck stature 1 is (as Fig. 1, shown in Fig. 4), it is left, the each tool wheel carrier 11 in right both sides is with the front-wheel 101 that is pivoted respectively, 102, and above it, be provided with connection tube 12, bundle folder 13 or other Quick-dismantle component (not shown) is equiped with above described connection tube 12, connect for bicycle seat cushion 6 (as shown in Figure 1) or babychair chair frame 5 (as shown in Figure 5) group, and the rear side of described front truck stature 1 has an inner sleeve 14 is used for connection one rear car stature 3, screw 141 is run through (as Fig. 1 before the front side of described inner sleeve 14 at least has one, shown in Fig. 4), and the rear side of described inner sleeve 14 runs through screw 142 after at least having one, described inner sleeve 14 is made to may correspond to grafting rear car stature 3, and through a locked assembly 7 described inner sleeve 14 and rear car stature 3 locked and engage or dismantle,

At least one handle rack 2, can lock juncture and aforementioned front truck stature 1 group connect;

One rear car stature 3, cording has the rear wheel fork 31 being positioned at rear side to connect a trailing wheel 311 with group, the top of described rear car stature 3 is provided with connection tube 33, on this top of connection tube 33 be equiped with second bundle folder 34 or other Quick-dismantle component (not shown) connect for bicycle seat cushion 6 (as shown in Figure 1) or babychair chair frame 5 (as shown in Figure 5) group, the front side of described rear car stature 3 has an outer tube 32 and is used for the inner sleeve 14 of front truck stature 1 described in corresponding sleeve, and the outer tube 32 of this rear car stature 3 be at least provided with one be positioned at front side before run through screw 321, can pass through described locked assembly 7 select with the inner sleeve 14 of described front truck stature 1 before run through screw 141 or after run through screw 142 and revolve interlocking and close or dismantle,
