At present, because of socio-economic development needs, various automobiles, motor bike becomes the main vehicle of life and work, because the increase of vehicle, traffic is more and more crowded, traffic congestion is seen everywhere, the phenomenon that the parking stall difficulty is looked for, bicycle is the modernized miniature vehicle of a kind of suitable short range rider and the not busy amusement of body, because its volume is little, the approximate people walking of floor area during rider, go out to be easy to carry about with one, and be loved by the people, existing society has the Kickboard Scooter structure as shown in Figure 1, connect car body (13) and wheel mount (5) by a folding arm device (11), rear wheel (12) is housed behind the car body (13), front vehicle wheel (14) is loaded on the wheel mount (5), handle rack (16) but receive in the placement positioning pipes (6), as shown in Figure 2, registration arm (6) is longer than handle rack (16), as Fig. 3, Fig. 4, shown in Figure 5, registration arm (6) is up-small and down-big stepped body, there is an open slot (64) pipe (52) that is coupling to be installed in the wheel mount (5) vertically in lower end (62), the lower end of registration arm (6) is established (62) and is enclosed within outside the pipe (52) that is coupling, and it is fixing with pipe collar (65), handle rack (16) can insert in the endoporus (53) of pipe (52) that are coupling, be that the same registration arm of handle rack (16) (6) is to wheel mount (5) bottom equal length, as shown in Figure 6, hole at trailing wheel locating rack (3), connect hub cap (4) by lock shaft (9), the inside face of hub cap (4) is provided with the lonely face (5) of the brake that matches with trailing wheel (2), braking worker boss (10) at trailing wheel locating rack (3), main body of vehicle frame (1) bores a screw (8) from bottom to top near the place of rear wheel (2), one end of an elastic element (6) is by being fixed on the main body of vehicle frame (1) because of locking bolt (7) of cooperating with screw (8), the other end of elastic element (6) is butted on the inside face of hub cap (4), and elastic element (6) constitutes by one.This shows, the scooter that current social occurs, Kickboard Scooter is at folding device, and brake gear is unsatisfactory.

It is a kind of multiple functional that the purpose of this utility model is to provide, and volume is little, the step treadmill of head.

The technical scheme that the utility model adopted is, by handle bracing frame, registration arm, wheel mount, front vehicle wheel, rear wheel, the bicycle that rear wheel lid etc. constitute, handle bracing frame and registration arm are with isometric, and handle props up and falls the fixer flexible positioning, at car body and front vehicle wheel head is set partly, be convenient to be locked in car use location and the car collection rear wheel lid inboard miniature coil spring is set, form brake gear, handle adopts left and right active type, and installation easy to use and folding is deposited.

Advantage of the present utility model is that technology is ingenious, and is rational in infrastructure, deposits easy, the people who fully satisfies different heights fixes handle bracing frame diverse location, the wheel cover brake gear that internal layer forms of applying in a flexible way is controlled road speed, the safety that makes car have reality, interest.
