Preferred as one, be positioned at latch that described movable arm has been permanently connected, described latch is socketed with ring, described ring is also connected with one end of torsion spring, and the other end of described torsion spring is connected on movable arm, and one end of described ring is provided with directed card, the other end of described ring is provided with sense-finding switch, be positioned near ring at described connection box and be provided with positioning groove, stir described ring and make directed card snap in positioning groove, for the action of restraint arm.
Preferred as one, described left-hand tread plate and right-hand tread plate are respectively arranged with left socle connecting strap and right support connecting strap, described left socle connecting strap and right support connecting strap are provided with connecting bore, described vehicle frame is provided with bolt switch, it is interior for both being fixedly connected with the connecting bore on right support connecting strap that described bolt switch can stretch into left socle connecting strap, and described bolt switch also overlaps outward retracing spring.
Preferred as one, described handlebar is provided with brake handle, described brake is connecting brake cable.
In sum, the utility model has following advantage:
The utility model compact conformation, structure is simple, can realize the automatic rebounding after trailing wheel sidesway, can be laborsaving, reduces operation easier, and increasing slides experiences enjoyment.And the setting of ring structure, can realize the fixing of trailing wheel, limiting it swings, and adds different playing methods.And left and right pedal can separate or combine, add again a kind of playing method, retracing spring can avoid the interference of the left and right support connecting strap of bolt Switch Controller simultaneously.
