ABSTRACT:
A locking mechanism for the head tube of a bicycle in which the two ends of the head tube are respectively provided with a horizontal race and a vertical race. The horizontal race is provided for the handlebar to feed through, and the vertical race cooperates with a vertical tube for locking. The wall of the vertical race is provided with a feed-through lateral passage, which communicates with the vertical race through an intersecting hole. A stop member is placed inside the intersecting hole, and the two sides of the stop member are respectively provided with a push member. The side of the stop member facing the vertical race is provided with a recessed arc surface, and the opposite side is a V-shaped protruded portion, which is provided with a fixed ring. The two push members are respectively provided with a screw hole for a stove bolt to feed through so that the fixed ring can be locked together. The inner surfaces of the push members are slanted surfaces which correspond to the V-shaped protruded portion of the stop member therefore the stop member can be pushed toward the vertical race, allowing the stop member to push against the vertical tube for retaining.
