1. A cutting machine comprising:
a spindle extending in a first direction to hold a processing tool to cut a plurality of processing targets;
a holder located below the spindle to hold the plurality of the processing targets;
a plurality of fixing pins that are each attached to a respective one of the plurality of processing targets;
a rotation shaft extending in a second direction intersecting the first direction and rotating about the second direction; and
a rotation support connected to the rotation shaft to rotatably support the holder; wherein
the holder includes:
a first holder including a plurality of first fixing portions and fixed to the rotation support, a first portion of the plurality of the fixing pins being fixed to the plurality of the first fixing portions; and
a second holder including a plurality of second fixing portions and being detachably attached to the first holder, the plurality of the second fixing portions being directly across from the plurality of the first fixing portions with respect to the second direction, and a second portion of the plurality of the fixing pins being fixed to the plurality of the second fixing portions;

the first holder includes a body extending in a third direction intersecting the first direction and the second direction, the first holder having a straight shape in plan view,
the plurality of the first fixing portions and the plurality of the second fixing portions are provided in the third direction,
the plurality of the fixing pins is fixed to the plurality of the first fixing portions and the plurality of the second fixing portions to extend in the second direction;
a distance in the second direction between a first portion of the plurality of the processing targets that are attached to the first portion of the plurality of the fixing pins and a second portion of the plurality of the processing targets that are attached to the second portion of the plurality of fixing pins is shorter than a length of the plurality of the fixing pins;
the second holder is detachably attached to the first holder with respect to the first direction;
one of the first holder and the second holder includes a first coupling portion including a screw hole in which a fastening screw is inserted;
another one of the first holder and the second holder includes a second coupling portion including a locking recess in which the fastening screw is locked;
a front end portion of the fastening screw in a direction along a longitudinal axis of the fastening screw has a first sloped surface that tilts inward from an outer circumference of the fastening screw toward an end surface of the fastening screw, and the end surface of the fastening screw includes a flat surface connected to a front end of the first sloped surface;
the locking recess includes a through hole, the through hole having a second sloped surface that is in contact with the first sloped surface of the fastening screw, the second sloped surface of the through hole tilting outward from an upper end of the through hole toward an upper end of the locking recess; and
in response to the second holder being attached to the first holder, the longitudinal axis of the fastening screw shifts from a center axis of the locking recess with respect to the second direction.
