    • A portable cutting-guidance apparatus is used with a portable, hand-holdable power saw (20) to make an angle-cut in an object at a variably selected angle. A positioning device (300) is positioned motionless against the object being cut. The saw (20) travels on and along a cutting-guide (100) in a straight line. The linear cutting-guide (100) is pivotally connected to the positioning device (300) about a pivot point (400). The linear cutting guide (100) can be adjustably fastened to the positioning means (300) at a variably selected angle. The positioning device (300) can be positioned and held against the object purely by the manual force of the user, which includes force with which the user pushes the power saw forwards along the cutting-guide to cut the object. The pivot point (400) is located a distance (y) away from the leading edge of the linear cutting-guide (100) to provide improved performance.
    • 便携式切割引导装置与便携式手持式电动锯(20)一起使用,以可变的角度对物体进行角度切割。 定位装置(300)相对于被切割的物体不动地定位。 锯(20)在切割导向器(100)上并沿着直线行进。 线性切割导向器100围绕枢转点(400)枢转地连接到定位装置300。 线性切割引导件(100)可以可变地选择的角度可调节地紧固到定位装置(300)。 定位装置(300)可以纯粹地通过使用者的手动力定位和固定在物体上,其包括使用者沿着切割导向器向前推动动力锯的力,以切割物体。 枢转点(400)位于远离线性切割导向器(100)的前缘的距离(y)处以提供改进的性能。
