As a further improvement of the above technical solution:

turn to stopper and headstock intraductal wall welding, the cover is established on the front fork director, and the both sides that turn to the stopper extend along axial symmetry has the dog, forms spacing breach between two dogs, be equipped with on the front fork director and be used for wearing to establish the through-hole of spacer pin, the spacer pin is located the central point of spacing breach puts the department, when the front fork director is rotated to the left and right sides along with the handlebar, and the spacer pin is blockked when rotating the dog to both sides.

The length of the limit pin and the outer diameter of the limit stop are both smaller than the inner diameter of the front forklift head pipe.

The clamping piece is of an annular structure and assembled with the front forklift head pipe pressing bowl to fix the front fork direction indicator and the front forklift head pipe.

The utility model has the advantages as follows:

the utility model discloses compact structure, reasonable, convenient operation hides the setting in stopper, the spacer pin of turning to, and both mutually support and play the limit to the effect, promote the appearance performance, and simple structure is reliable, and production manufacturability is good.

The spacer pin is fixed with the front fork direction device, turns to that stopper and headstock pipe are fixed, when the spacer pin rotates along with the front fork direction device, thereby receives to turn to the stopper stop the restriction left and right sides rotation direction, the spacer pin is located the central point who turns to between the stopper both sides dog and puts, and the contained angle that is between the dog 71 of both sides is 45 degrees respectively, the angle that turns to of restriction handlebar promptly is 45, through the reasonable angle that sets up, can realize different turned angle's control and adjustment.
