Work tool

A power tool configured to drive a tool accessory removably held between a first clamp part and a second clamp part, comprising:

• a first shaft having the first clamp part,
• a second shaft having the second clamp part,
• a holding member configured to fixedly hold the second shaft with respect to the first shaft,
• a moving member configured to move the holding member, and
• a first biasing member biasing the moving member,
• wherein:
• the first shaft and the second shaft are disposed such that their axes extend in parallel to each other and the second shaft is disposed inside the first shaft,
• the holding member is configured to be movable between a first position in which the holding member is capable of holding the second shaft and a second position in which the holding member is incapable of holding the second shaft,
• the moving member is configured to move the holding member from the first position to the second position,
• the first biasing member is configured to bias the moving member when the holding member is located in the second position, and thereby prevent movement of the moving member,
• the moving member has a locking member which is biased by the first biasing member,
• the first biasing member is disposed so as to apply a biasing force in a radial direction of the first shaft, and
• when the locking member is biased by the first biasing member and comes in contact with the first shaft, movement of the moving member is prevented in a longitudinal direction of the first shaft.
