<P>PROBLEM TO BE SOLVED: To provide a height-adjusting assembly for a shaft, which can adjust the position of the height-adjusting assembly relative to the shaft as desired. <P>SOLUTION: The height-adjusting assembly for a shaft has an outer device, an inner device and multiple positioning elements. The outer device is adapted to mount around the outer surface of a shaft and has a base and a mounting casing. The mounting casing is mounted around the base and has a chamber, an opening and a cone surface. The inner device is movably connected to the outer device and has a moving mount and at least one spring. The moving mount is mounted in the outer device and has a mounting chamber, a pressing segment and multiple positioning holes. The spring is mounted between the base and the moving mount to enable the positioning holes to face the cone surface. The positioning elements are respectively mounted in the positioning holes of the moving mount and abut on the cone surface and the shaft to hold the height-adjusting assembly on the shaft. <P>COPYRIGHT: (C)2012,JPO&INPIT |
