Portable cutting machine
A suspending member, such as a tether strap or the like, may by connected to improve convenience for an operator. The function of the suspending member shall be reliably performed by clearly notifying the user when the connecting part for connecting the suspending member is damaged. A ring-shaped notification member is incorporated in a connecting part for connecting the suspending member. The suspending member is inserted into both of a connecting hole in a connecting part and a notification member so as to be connected. When an end of a handle portion breaks due to long-term use, the notification member is pulled out such that the damage of the connecting part is notified.
1. A portable cutting machine configured to perform a cutting process, comprising:
an electric motor configured to rotate a rotary cutting tool so as to cut a cutting material;
a housing that includes (i) a motor housing that houses the electric motor and (ii) a handle configured to be gripped by a hand of a user of the portable cutting machine; and
a notification piece; wherein:
the handle includes a connecting part that is configured to receive and retain a suspending piece that is configured to be also supported by a separate component from the portable cutting machine; and
the notification piece (i) has a first end connected to an inside of the handle by a fastener and a second end configured to be attached to the suspending piece and (ii) is configured to deform such that the second end moves outside of the handle due to force by the suspending piece to provide a notification of damage to the connecting part when the connecting part is damaged or broken.
2. The portable cutting machine as described in claim 1 , wherein the connecting part and/or the notification piece includes a connecting hole that is configured to receive the suspending piece.
3. The portable cutting machine as described in claim 2 , wherein the connecting part and the notification piece are configured such that the suspending piece can be inserted through an inner peripheral side of the notification piece and the connecting hole so as to be connected to the connecting part.
4. The portable cutting machine as described in claim 2 , wherein
the connecting part is configured such that the suspending piece is insertable into the connecting hole so as to be connected to the connecting part.
5. The portable cutting machine as described in claim 1 , wherein the notification piece is a ring-shaped wire.
6. The portable cutting machine as described in claim 1 , wherein:
the notification piece is configured to visually indicate to a user of the portable cutting tool of damage to the connecting part by rotation or deformation of the notification piece with respect to the first end such that the second end of the notification piece moves from inside to outside the handle.
7. The portable cutting machine as described in claim 1 , further comprising a base (i) having a flat plate shape and (ii) configured to contact an upper surface of the cutting material when the portable cutting machine cuts the cutting material, wherein:
the housing includes the connecting part that extends along the rotary cutting tool; and
the connecting part and the notification piece are at a rear part of the connecting part; and
the rear part of the connecting part is on an opposite side of the motor from a front part of the base.
8. The portable cutting machine as described in claim 1 , wherein:
the notification piece and the connecting part are configured such that the second end of the notification piece and the connecting part receive a loop of the suspending piece that is looped around the second end and the connecting piece to affix the suspending piece to the second end and the connecting piece; and
the first end of the notification piece is affixed to the handle by the fastener.
