摘要： A miter saw includes a miter saw for placing a work thereon, a miter saw unit having a saw blade mounted thereon, and a support mechanism for supporting the miter saw unit for rightward and leftward pivotal movement relative to the base. The support mechanism includes a first member on one side of the base and the miter saw unit and a second member on the other side of the base and the miter saw unit. The first member and the second member are pivotable relative to each other about a pivotal axis. A stopper mechanism is disposed between the first member and the second member for holding the miter saw unit in a vertical position. The stopper mechanism includes a first pressing member mounted on the first member, a first biasing member for biasing the first pressing member, and an abutting surface provided on the second member for abutment of the first pressing member. The abutting surface has a first recess formed therein. The pressing member is brought to automatically engage the first recess by the biasing force of the first biasing member when the miter saw unit is pivoted from a laterally pivoted position to the vertical position.

摘要： A cutting device, such as a beveling miter saw, includes a base, a work table supported on the base, and a cutting unit operably connected to the base. The work table includes a workpiece support surface and a stop portion. The cutting unit is selectively rotatable about a first axis between leftward and rightward bevel positions relative to the workpiece support surface. A rotatable stop member is coupled to the cutting unit and is selectively rotatable relative to the cutting unit to selectively contact the stop portion to thereby prevent rotation of the cutting unit in one direction about the first axis. The rotatable stop member and the stop portion may be positioned so that those elements contact when the cutting unit is at a predetermined bevel position, such as a vertical (0°) bevel position, relative to the workpiece support surface.

摘要： An improved base structure of a circular saw includes a base, a rotatable base plate mounted on the base, a mounting seat, and a rotary seat. The base plate has an upper face provided with a recess at a rear end. The mounting seat is screwably secured on both sides of the recess, and has a pivot portion with a screw hole at a bottom end. The pivot portion is located in the recess. The rotary seat can rotate relative to the mounting seat and is provided with a curved slide groove for receiving an adjusting screw. The rotary seat has a pivot portion at a bottom end that corresponds to the pivot portion of the mounting seat. The pivot portion of the rotary seat has a shaft hole that corresponds to the screw hole of the pivot portion of the mounting seat, whereby they are coaxially joined by a pivot that connects the pivot portions integrally to the recess of the base plate, so that the rotary seat can rotate utilizing the pivot as center of rotation and allow adjustment of inclination relative to the upper face of the base plate.
摘要翻译：圆锯的改进的基部结构包括基座，安装在基座上的可旋转底板，安装座和旋转座。基板具有在后端设置有凹部的上表面。安装座可滑动地固定在凹部的两侧，并且具有在底端处具有螺钉孔的枢转部分。枢轴部分位于凹槽中。旋转座可以相对于安装座旋转，并且设置有用于容纳调节螺钉的弯曲滑动槽。旋转座具有在与安装座的枢转部对应的底端的枢转部。旋转座的枢转部分具有与安装座的枢转部分的螺孔相对应的轴孔，由此通过将枢转部分整体连接到基板的凹部的枢轴同轴接合，使得旋转座可以利用枢轴作为旋转中心旋转，并且允许相对于基板的上表面调整倾斜度。
