摘要： A cutting device main body with a saw blade in a tabletop cutting device, supported so as to be swingable in an up-to-down direction with respect to a table on which material to be cut is placed, aims to improve operability for attaching and detaching the battery. A sliding direction for attaching and detaching the battery is set to be a tilting direction angled with respect to an up-to-down moving direction of the cutting device main body in a surface direction of a cutting blade. Because of this configuration, all of an operation force for attaching and detaching the battery is not applied to the up-to-down moving direction of the cutting device main body. As a result, the cutting main body is not moved in an easy manner and operability for attaching and detaching the battery is improved.

摘要： Blade guards for power tools such as table saws are disclosed. The blade guard may include a guard that pivots up and down to allow a workpiece to move past the guard, a dust collection channel, and a pivot mechanism which maintains the dust collection channel in an operable condition as the guard pivots up or down. The guard may also function as a wood stop and it may include anti-kickback pawls. The blade guard may be part of a dust collection system and may be connected to a vacuum system by a conduit such as a flexible hose.

摘要： A sawmill 1 has an operator end 6, a pair of end frames 2, a track 3 elevated by and extending from at least one end frame to the other, a carriage moveable 4 to carry a saw 5 along at least part of the track, flip elements able to move the saw from a horizontal cutting orientation to a vertical cutting orientation, and a relocatable stopper 13 associated with the track. The carriage 4 can be driven away from the operator end 16 with the saw 5 in the horizontal cutting orientation to contact the stopper 13 when the carriage, this resulting in the flip elements automatically moving the saw 4 into the vertical cutting orientation.

摘要： To provide a cutting machine that suppresses swinging of the cutting portion when the battery pack is attached or detached, the cutting machine includes a cutting portion, a base, and a swing support mechanism. The cutting portion includes: a motor, a motor housing accommodating the motor, an output shaft configured to be rotated upon rotation of the motor, a battery pack serving as a power source of the motor, and a battery pack attaching portion including a pair of rail portions with which the battery pack is engageable, where a cutting blade is configured to be detachably attached to the output shaft. The base has a contact surface on which a workpiece is configured to be placed. The swing support mechanism is connected to the base and the cutting portion and includes a swing shaft extending in parallel to the output shaft. The swing support mechanism supporting the cutting portion such that the cutting portion is swingable about the swing shaft between a top dead center and a bottom dead center in a direction parallel to a side surface of the cutting blade. The pair of rail portions extend in a direction crossing the side surface of the cutting blade.

摘要： A multi-link miter saw includes a base, a table supported on the base, a supporting unit connected to the table, a linkage unit connected to the supporting unit, a cantilever arm unit including a cantilever arm pivotally connected to the linkage unit and a connection member pivotally connected between the cantilever arm and the linkage unit for enabling the cantilever arm to be driven by the linkage unit and the connection member to move along a horizontal axis between the rear edge and front edge of the base, and a cutting unit pivotally connected to the cantilever arm unit. Based on the arrangement of the linkage unit and the cantilever arm unit, the cutting unit can be moved smoothly relative to the table, thus enhancing operation stability.

摘要： Disclosed is an electric mitre saw, comprising a base (1), a work bench (2), a saw mechanism, and a swing arm (4), wherein a plurality of layers of slide rails (5, 11) extending in a horizontal direction are provided on the swing arm (4), with the plurality of layers of slide rails (5, 11) being able to slide horizontally relative to each other by means of a slide block (6), a rotary shaft (10) is provided on one layer of the slide rails (11) farthest away from the swing arm (4), and the saw mechanism is rotatably connected to the rotary shaft (10). By means of the arrangement of the plurality of layers of slide rails (5, 11), the length of each layer of slide rails is relatively short, the manufacturing difficulty is reduced, there is a saving in the working space of the miter saw, and the packaging volume is reduced. When one layer of slide rails (5, 11) is respectively arranged at both sides of a saw blade (15), the end parts of two slide rails of each layer of slide rails (5, 11) are able to be connected by a connecting seat (8, 14), thus facilitating the improvement of parallelism of the two slide rails (5, 11), and providing a greater cutting travel. A gripping space is also formed between the two layers of slide rails (5, 11), such that observation during cutting is convenient.
摘要翻译： 公开了一种电动斜切锯，包括基座（1），工作台（2），锯机构和摆臂（4），其中多个在水平方向上延伸的滑轨（5,11） 方向设置在摆臂（4）上，多个滑轨层（5,11）能够通过滑动块（6）相对于彼此水平滑动，旋转轴（10）是 设置在离摆臂（4）最远的滑轨的一层上，锯机构可旋转地连接到旋转轴（10）。 通过多层滑轨（5,11）的布置，每层滑轨的长度相对较短，制造难度降低，节省了斜切锯的工作空间， 并且包装体积减小。 当一层滑轨（5,11）分别布置在锯片（15）的两侧时，每层滑轨（5,11）的两个滑轨的端部能够通过 连接座（8,14），从而有助于改进两个滑轨（5,11）的平行度，并提供更大的切割行程。 在两层滑轨（5,11）之间也形成夹紧空间，使切割时的观察方便。
