The tilt-fixing mechanism includes a manually rotatable tilt-fixing manipulatable part (61; 81; 101) provided between the front surface of the table-extension part and the grip. A rotary shaft (61a; 82a; 102a) of the tilt-fixing manipulatable part is coaxial with the fixing rod (rotary shaft) attached to the grip.

The disclosure provides a sawing machine, including: a base; a main workbench rotatably connected to the base, an upper surface of the main workbench being provided with a chute, the chute extending in a first direction; a machine body slidably connected to the main workbench, a sliding direction of the machine body being parallel to the first direction, the machine body being provided with a motor and a saw blade connected to the motor; an auxiliary workbench being slidably inserted into the chute and protruded out of the chute from an open end, an upper surface of the auxiliary workbench is provided with an elongated groove, the groove extends in the first direction, the groove and the chute are in communication in the first direction and form an extendable saw blade slot. In the present disclosure, the cutting distance of the sawing machine can be extended, without increasing the overall volume of the sawing machine, increasing the packaging size, and increasing the transportation cost.

A miter saw with a pivotally rotatable extension includes a base, a worktable, a cutting member, and an extension member. The base has a pair of lateral edges oppositely extending along a longitudinal direction, a top surface correspondingly engaged to each lateral edge. The worktable is rotatably mounted to the base, and has a work surface corresponding to the top surface. The cutting member is connected to the worktable. The extension member is pivotally mounted to one of the lateral sides of the base. The extension member is convertible between an extended position and a retracted position relative to the base. The extension member has an extension surface. At the extended position, the extension surface is engaged to the top surface longitudinally for supporting a workpiece. At the retracted position, the extension surface is substantially perpendicular to the top surface for minimizing the size of the miter saw.

An illuminator that emits light from a radially outer portion of the cutting tool toward the cutting tool includes a first light source and a second light source, and a first lens and a second lens. The first lens has a first emission surface including a first outermost portion located farthest and at a first distance from a first center axis including a first light source center of the first light source and perpendicular to the first light source. The second lens has a second emission surface including a second outermost portion located farthest and at a second distance from a second center axis including a second light source center of the second light source and perpendicular to the second light source. A distance between the first center axis and the second center axis is shorter than a sum of the first distance and the second distance.

A miter saw has a base assembly, a table rotatably disposed on the base assembly, a support section rotatably connected to the table, a guide bar fixedly attached to and extending forwardly from the support section, and a saw assembly sliding along the guide bar. The saw assembly is pivotable downwardly for cutting a workpiece disposed on the table. A handle is disposed adjacent to a forward end of the guide bar. The handle is movable between a first position for fixing a rotational position of the support section relative to the table, and a second position for allowing rotational movement of the support section relative to the table.

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.

A miter saw that includes a base, a worktable arranged on the base and defining a worktable plane, and a cutting head formed with or connected to an operating member operable by a user. The cutting head further includes a circular saw blade operative to rotate around a first axis and a motor operative to drive the circular saw blade. A fence is arranged on the worktable. The cutting head is further connected to a first guiding member configured for guiding chips to be discharged. The fence is formed with a guiding portion. The cutting head is operative to rotate around a second axis parallel to the worktable plane and, when the cutting head rotates around the second axis, the guiding portion is operative to guide the first guiding member to cross the fence.

A miter saw includes a base assembly and a saw unit pivotably coupled to the base assembly. The saw unit includes a saw arm, a brushless motor supported by the saw arm, and power electronics positioned outside the motor for supplying power to the motor. The power electronics are coupled to a structural component of the miter saw to utilize the entire mass of the structural component as a heat sink to dissipate heat generated by the power electronics.

A bevel angle lock and detent system for a miter saw includes a first locking unit fixed relative to the turntable and a second locking unit coupled to a bevel arm of the miter saw. An actuator is moveable between a first position and a second position to move the second locking unit relative to the first locking unit. In the first position, a brake member of the second locking unit is engaged with an arcuate surface of the first locking unit to lock a saw unit relative to a turntable. In the second position, the brake member is disengaged from the arcuate surface, thereby permitting pivoting movement of the saw unit, and a detent member of the second locking unit is engageable a detent aperture of the first locking unit to locate the saw unit relative to the turntable at one predetermined bevel angle.

A saw machine worktable positioning mechanism includes a pivot shaft, an operating member and a first positioning unit so arranged that operating the operating member can drive the first positioning unit to move a positioning member of the first positioning unit relative to the base of the saw machine in one of two reversed directions to lock the worktable of the saw machine to the base or to unlock the worktable from the base.
