  • Patent number: 11813768
    Abstract: An attachment structure for attaching an auxiliary fitting such as a parallel ruler to a portable machining apparatus allows simpler assembly and maintenance. A portable machining apparatus includes a base having a lower surface to be in contact with a workpiece, a machining body supported on an upper surface of the base, and a mount that receives an auxiliary fitting removably attachable to the base. The mount includes an internal threaded fastener detachably supported on the base, an external threaded fastener screwed with the internal threaded fastener to be tightened with the internal threaded fastener to press the auxiliary fitting onto the base, and a locking section that locks the external threaded fastener with respect to the internal threaded fastener.

  • Patent number: 11285598
    Abstract: A bracket (20) includes: a pedestal (21, 22) that is mountable on a support frame (2) of a work stand (1) for supporting a saw (60); and first and second engaging parts (38A, 38B) arranged on the pedestal to sandwich the support frame in a horizontal direction and engage with first and second engagement parts (8A, 8B) on opposite sides of the support frame. The second engaging part includes first and second levers (41, 42). The pedestal is movable along the longitudinal direction of the support frame by manipulating only the first lever to disengage it from the second engagement part (8B) and is removable from the support frame by simultaneously manipulating both the first and second levers in the same direction to disengage them from the second engagement part. The first and second levers both move in the same opposite direction to engage the second engagement part.

  • Publication number: 20190314908
    Abstract: An operation knob is attached to one end of a transmission rod. The transmission rod is located in a slide bar supporting a cutting device main body so as to be slidable in a front-to-rear direction. A pulley of a belt transmission mechanism is joined to the other end of the transmission rod, and a click mechanism is arranged around a portion of the pulley. The click mechanism provides a tactile sensation (e.g. click feeling or feeling of moderation) and improves operability of the operation knob.

  • Patent number: 8813376
    Abstract: A cutting machine includes a housing accommodating a motor. In the housing, a cutting blade, an air duct, a dust collecting channel and a shutter member are provided. The cutting blade is operated with the driven motor to cut a workpiece, and the air duct allows cooling air generated by a cooling fan for the motor to be blown out onto a cutting place of the workpiece. The dust collecting channel has an opening at one end for serving as a dust collecting port located near the cutting place and an opening at the other end for permitting coupling of a dust collecting nozzle. The shutter member is movable between a closed position and an open position of the air duct and located in the open position in a normal state.

  • Patent number: 8490528
    Abstract: A cutting device includes a positioning mechanism for positioning a cutting unit at a plurality of tilt angles including a first tilt angle and a second tilt angle in a left direction and/or a right direction. The first tilt angle is larger than the second tilt angle. A setting state for the first tilt angle is reset to a setting state for the second tilt angle when a positioning state at the first tilt angle is released.
