10014127 · 2018-07-03 · ·

A safety lock mechanism mounted at a trigger switch handle of a miter saw to face toward a switch which includes a switch button pivotally mounted at the trigger switch handle to face toward the switch, and a safety lock connected to the switch button and providing an engaging portion and movable between a locking position where the engaging portion engages into the trigger switch handle to lock the switch button to the trigger switch handle and an unlocking position where the engaging portion is disengaged from the trigger switch handle for allowing the switch button to be moved relative to the trigger switch handle to trigger the switch. Thus, the arrangement of the safety lock prevents the user from accidentally forcing the switch button to trigger the switch, enhancing the operational safety of the miter saw.

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.

09975190 · 2018-05-22 · ·

The present invention relates to a portable power tool (1) arranged for driving a rotatable cutting tool (2). The power tool (1) comprises a motor (5) and a transmission part (4) that is arranged to transfer power from the motor (5) to a tool holder (10), and comprises a first arm part (11; 11) and a second arm part (12; 12). The first arm part (11; 11) comprises a first belt pulley (13) and the second arm part comprises a second belt pulley (14), the arm parts (11, 12; 11, 12) being slidably connected to each other. The belt pulleys (13, 14) are spaced apart by a certain distance (d-i, d2). The transmission part (4) further comprises a tensioning device (20) with a rod (21), a pre-tensioned resilient device (22), a linkage arrangement (25) and a rotatable part (26). The rotatable part (26) is rotatable between a first, released, state where the belt pulleys (13, 14) are spaced apart by a first distance (d-i), and a second, tightened, state where the belt pulleys (13,14) are spaced apart by a second distance (d2) that exceeds the first distance (d-i), the resilient device (22) being more compressed in the second state than in the first state.
