Patent attributes
A power tool for driving an accessary removably held between first and second clamp parts includes a first shaft having the first clamp part, a second shaft for moving the second clamp part, a holding member movable relative to the second shaft, a moving member for moving the holding member, and a biasing member for biasing the moving member. The second shaft is disposed inside the first shaft. The holding member enables the second clamp part and the first clamp part to hold the tool accessary therebetween in a first position, and disables the second clamp part and the first clamp part from holding the tool accessary in a second position. The moving member moves the holding member from the first position to the second position, and the biasing member biases the moving member when the holding member is located in the second position.
