  • Patent number: 11135712
    Abstract: A driving tool drives a fastener by a striking mechanism. The driving tool includes a trigger, a contact arm, a contact lever and a regulator. The trigger and the contact arm receive manipulations which operate the striking mechanism. The contact lever is movable according to operations of the trigger and the contact arm and switches operating states of the striking mechanism. The regulator regulates a movement of the contact lever according to a movement of the contact arm in which another manipulation is released. The regulator operates with a fluid for operating the striking mechanism, and keeps the contact lever at an operation standby position where the contact lever is operated by manipulation of the contact arm for a predetermined time period by controlling a flow rate of the fluid.
    Type: Grant
