Bearing adjuster

A bearing adjuster comprising:

• a grip including an impact receiver disposed thereon to provide for receiving impact form external forces;
• a rotatable wheel mounted with the grip, the rotatable wheel having a through hole centrally defined therein, the rotatable wheel having multiple arc grooves spirally and concentrically defined in a bottom thereof;
• an adjusting member having a spindle extending from a top thereof, the spindle connected to the grip via the through hole in the rotatable wheel, the adjusting member having multiple grooves radially defined therein for corresponding to the multiple arc grooves, each groove having a movable member movably received therein, each movable member having a stub extended from a top thereof and received in a corresponding one of the multiple arc grooves in the rotatable wheel;
• wherein the rotatable wheel is rotatable relative to the grip and the adjusting member;
• when the rotatable wheel is rotated, the stub of each movable is pressed by the corresponding arc groove to move along the corresponding groove in the adjusting member such that each movable member is moved along the corresponding groove for adjusting a distance between each other for adapted to assemble with bearings having different sizes.
