Patent ID: 8216028

Claim:
An installation/uninstallation structure for tooling disk of a grinding tool, comprising a rotary shaft mounted in a grinding tool and a securing assembly, wherein: the rotary shaft has a rear end, an annular groove being formed on a circumference of the rear end of the rotary shaft; the securing assembly includes a securing seat, a shift plate and a securing member; the securing seat having a through hole passing through the securing seat from a top face to a bottom face thereof; a slide way being radially formed on a rear side of the securing seat, an inner end of the slide way communicating with the through hole; the shift plate being pivotally disposed on the securing seat and movable between a locking position and an unlocking position; the securing member being mounted in the slide way of the securing seat and slidable within the slide way, the securing member having a front end as an abutment end; the securing member being connected with the shift plate by means of a link, whereby when shifting the shift plate, the shift plate via the link drives the securing member to move within the slide way; and the securing assembly being fitted on the rear end of the rotary shaft with the rotary shaft passing through the through hole of the securing seat; when the shift plate is shifted to the locking position, the shift plate driving the securing member to move toward an inner end of the slide way and making the abutment end of the securing member move into the through hole to be latched in the annular groove of the rotary shaft, whereby the securing assembly is secured to the rotary shaft for fixing the tooling disk; when the shift plate is shifted to the unlocking position, the shift plate driving the securing member to move toward an outer end of the slide way and making the abutment end of the securing member move out of the annular groove, whereby the securing assembly can be detached from the rotary shaft for taking off the tooling disk.
