During handlebar, handlebar rotary spacing projection rotates with handlebar, when handlebar rotary spacing projection turns to the two of rotary spacing deep-slotted chip breaker
During end position, the both ends that handlebar rotary spacing projection is rotated spacing deep-slotted chip breaker are withstood, and can not be rotated further by, so as to play restriction car
The effect of rotational angle, when being turned round so as to effectively prevent user from cycling, excessive velocities and handlebar rotational angle is excessive, causes
Bicycle overturns.
The upper end of the front truck wheel arm is provided with connection rotating shaft, and the front portion of the main body of vehicle frame is provided with sleeve pipe, the handlebar
Rotary spacing deep-slotted chip breaker is arranged on the outer wall of sleeve pipe along the circumferential direction of sleeve pipe, and the connection rotating shaft passes through sleeve pipe and and handlebar
It is fixedly connected, connection rotating shaft is rotatably arranged in sleeve pipe.
On the lower end outer wall of sleeve pipe, raised slide of the handlebar rotary spacing sets the handlebar rotary spacing deep-slotted chip breaker
Put in handlebar rotary spacing deep-slotted chip breaker, the handlebar rotary spacing is raised on the transverse arm of front truck wheel arm.
The radian C of the handlebar rotary spacing deep-slotted chip breaker is 80 ° -150 °, and the radian C of rotary spacing deep-slotted chip breaker is preferably
120°。
The beneficial effects of the utility model are as follows：
（One）Front truck wheel arm of the present utility model is in single armed shape, and front truck wheel arm and the connection at an acute angle of front truck wheel shaft, phase
Front truck wheel arm more connected vertically than existing bicycle and the connected mode of front vehicle wheel axletree, front truck wheel arm of the present utility model
Structure is more firm, stress is more preferable, more reasonable.
（Two）It is provided between front truck wheel arm of the present utility model and the front portion of main body of vehicle frame and is used to limit handlebar rotational angle
Handlebar rotary position limiting structure, when being turned round so as to effectively prevent user from cycling, excessive velocities and handlebar rotational angle is excessive, from
Driving is easily overturned.
