Portable milling machine having a spanner

A portable milling machine comprising:

• a housing;
• a spindle;
• a tool holder having a clamping nut rotatably connectable to the spindle and detachable from the spindle in order to clamp and unclamp a milling tool;
• and
• a spanner movable relative to the spindle axially between an engaged position and a disengaged position, the spanner interlockingly surrounding the clamping nut at least in portions in the circumferential direction in the engaged position and, when the spanner is in the disengaged position, the clamping nut being rotatable relative to the spanner, the spanner being connected to the housing for conjoint rotation such that, when the spanner is in the engaged position, the clamping nut is connectable to the spindle and detachable from the spindle by manually rotating the spindle;
• wherein the portable milling machine has an upper sleeve and a lower sleeve on a tool side, the upper sleeve and the lower sleeve each having a manual operation surface and being arranged coaxially with the spindle;
• and
• wherein the upper sleeve is connected to a spindle key for conjoint rotation such that, when the spanner is in the engaged position and the spindle key is in the blocked position, the clamping nut is connectable to the spindle and detachable from the spindle by manually rotating the upper sleeve.
