Abstract:
1. A holding apparatus for a power tool machine, the power tool machine including a base providing an operating surface for supporting a workpiece, and a fence mounted on the operating surface and having a standing surface substantially perpendicular to the operating surface arrange to be abutted by a side of the workpiece, and the holding apparatus comprising: a supporting device configured for mounting on the base of said power tool machine; a connecting device comprising a body connected to the supporting device, wherein a length direction of the connecting device is substantially perpendicular to a length direction of the supporting device; an adjustable device pivotally and slidably coupled to the connecting device, the adjustable device being slidable along the connecting device substantially in the length direction of the connecting device; and a pressing device connected to the adjustable device for selectively pressing another side of the workpiece; wherein the adjustable device provides a guide slot, and the connecting device has a guide pin extending from the body of the connecting device through the guide slot; and wherein the connecting device further comprises a first projection protruding out of the body, the adjustable device provides a locking notch, the guide slot substantially elongates along a straight line passing through the guide pin, and the perpendicular distance between the first projection and the straight line is larger than the perpendicular distance between the locking notch and the straight line when the straight line is substantially perpendicular to the length direction of the supporting device.
