POWER TOOL MACHINE WITH A HOLDING APPARATUS

Abstract

A power tool machine includes a base, a fence, a cutting arm, a motor, a saw blade and a holding apparatus. The base has an operating surface for supporting a workpiece. The fence mounted on the operating surface has a standing surface substantially perpendicular to the operating surface for abutted by a side of the workpiece. The cutting arm pivotally coupled to the base. The saw blade mounted to the cutting arm is rotatable by the motor. The holding apparatus includes a supporting device mounted on the base, a connecting device including 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 coupled to the connecting device, and a pressing device connected to the adjustable device for selectively pressing another side of the workpiece.
