1. a monoblock type can realize the headset of Fast Installation, including being arranged on the top headset of head tube (A) upper orifice (A1) and being arranged on the bottom headset of head tube (A) lower nozzle (A2), it is characterized in that:

  • described top headset is by headset (5) on washer (1), opening holding circle (2), upper bearing (metal) (3) and upper aluminum bowl (4) the mutually equipped a kind of monoblock type constituted;

    Described bottom headset is by headset (9) under lower aluminum bowl (6), lower bearing (7) and lower plug (8) the mutually equipped a kind of monoblock type constituted;

    The mode that in described monoblock type, headset (5) uses hands to press is pressed into the upper orifice (A1) of head tube (A), in this monoblock type, the upper aluminum bowl (4) of headset (5) has and can expand body (41) and annular bottom surface (42a) can be with the upper bowl annular boss (42) of the end face location fit suitable for reading of head tube (A) upper orifice (A1) by the inwall of shrinkage and expansion deformation side face and head tube (A) upper orifice (A1) the upper bowl of being close to join, and described upper bowl expands the radians such as the side face of body (41) and has multiple upper bowl inflationary gap (41a) that can allow the upper bowl expansion appropriate elastic deformation of body (41) external diameter;

    The mode that under described monoblock type, headset (9) uses hands to press is pressed into the lower nozzle (A2) of head tube (A), under this monoblock type, the lower aluminum bowl (6) of headset (9) has and can expand body (61) and annular top surface (62a) can be with the lower bowl annular boss (62) of the end opening end face location fit of head tube (A) lower nozzle (A2) by the inwall of shrinkage and expansion deformation side face and head tube (A) lower nozzle (A2) the lower bowl of being close to join, and described lower aluminum bowl expands the radians such as the side face of body (61) and has the lower bowl inflationary gap (61a) of multiple appropriate elastic deformation of external diameter that can allow lower bowl expansion body (61).
