摘要： Fanned air generated by a fan to cool a motor is discharged from a housing through fanned air discharge ports toward an opening formed in a base. The fanned air discharged toward the opening is then introduced into a groove in fluid communication with the opening. The groove is formed in a bottom surface of the base and has an open side at a front side of the base. The fanned air is then discharged from the front side of the base, blowing off saw dust on a cutting object so as to prevent dust from accumulating on a marking line on the cutting object.

摘要： A portable cutting machine is provided with a cutting machine main body, a surface plate rotatably supported by the cutting machine main body, a saw blade supported by the cutting machine main body rotatably around a first axis, and a lower guard supported by the cutting machine main body rotatably around a second axis. The first axis is located on one side of the surface plate. A part of the saw blade passes through an opening portion formed to penetrate through the surface plate and is exposed to the other side of the surface plate. The part of the saw blade exposed to the other side is covered by the lower guard. The first axis is parallel to the second axis. The first axis is located closer to a side of the surface plate than the second axis.

摘要： An electric circular saw of the type including a mechanism for tilting a base relative to the plane of a blade is provided wherein a side knob for being gripped by the user during cutting operation pivotally connects the base and a body of the circular saw through a base attachment portion and a bevel plate having an arcuate guide groove extending through an angular distance corresponding to a tilt angle of the base relative to the blade. The side knob is threaded to the base attachment portion and movable together with the base when the base is tilted. The side knob is spaced from a guide surface of the base by a distance at least larger than a maximum radius of the side knob. The distance between the base and the side knob is constant regardless of the relative angular position of said base and the blade, so that circular saw can be held stably and hence is capable of performing an accurate cutting operation.
摘要翻译：提供一种类型的电动圆锯，其包括用于相对于叶片的平面倾斜底座的机构，其中用于在切割操作期间由使用者夹持的侧旋钮将基座和圆锯的主体通过基座附接部分和斜板，其具有延伸通过对应于基部相对于叶片的倾斜角的角距离的弓形引导槽。当底座倾斜时，侧把手螺纹连接到基座安装部分并与基座一起移动。侧按钮与基座的引导表面间隔至少大于侧钮的最大半径的距离。基座和侧把手之间的距离与所述基座和叶片的相对角度位置无关，因此能够稳定地保持圆锯，因此能够进行精确的切割操作。
