Abstract
A work tool includes a spindle and a clamp shaft. The spindle is supported to be rotatable around a driving axis defining an up-down direction of the work tool. The clamp shaft includes a shaft part and a fixing part. The shaft part extends coaxially with the spindle. The fixing part is coupled to the shaft part on a lower side of the spindle. The clamp shaft is supported to be movable in the up-down direction relative to the spindle. The clamp shaft is configured to be biased upward and to fix the tool accessory to a lower end portion of the spindle by the fixing par. The fixing part is configured to be removable from the shaft part and to be integrally coupled to the shaft part only by moving upward relative to the shaft part.
