Abstract:
1. A driving tool comprising: an injection part defining a passage for a fastening piece; a lower pusher being provided in the injection part and extending in a longitudinal direction so as to be brought into contact with an object to be worked, the lower pusher having an elongated hole extending in the longitudinal direction; an upper pusher adapted to slide in the longitudinal direction in association with the lower pusher; a fixing part being in contact with the upper pusher and formed with a threaded hole; a bolt having a threaded part, a contact part, an engaging part and a flange part, the bolt being disposed to pass through the elongated hole of the lower pusher and to be screwed into the threaded hole of the fixing part so that the lower pusher is tightly connected with the fixing part; and a lever having a hole through which the bolt is passed, the lever being disposed between the flange part of the bolt and the fixing part and movable between a first position and a second position, wherein when the lever is at the first position, the hole of the lever is engaged with the engaging part of the bolt so that the bolt is rotated with the lever and when the lever is at the second position, the hole of the lever is positioned at the contact part of the bolt so that the bolt is not rotated with the lever, wherein the bolt is released from the fixing part by rotating the lever at the first position and the lower pusher is moved in the longitudinal direction in the elongated hole, and wherein a spring is interposed between the flange part of the bolt and the lever so that the lever is biased to take the second position.
