(F) A first microswitch provided on the side of the lever so that it is turned off when the lever is not rotated and turned on when the lever is rotated. (g) when the first microswitch and the second microswitch are turned on, each has an electric circuit that supplies power to the motor; (h) the cam is rotated by the motor to An electric nail gun, wherein a lever is rotated to disengage from the first microswitch and release the ram. (2) It has a motor brake that operates when the power is cut off, and the motor is quickly stopped after the power is cut off, and the distance between the cam and the ram is increased, so that the rotational speed of the cam is high when the motor is started next time. 2. The electric nail gun according to claim 1, wherein the driving operation by the ram is performed after reaching . (3) Connect the anode of the power supply directly to the anode of the motor and the NC contact of the first microswitch, connect the cathode of the power supply directly to the NO contacts of the first and second microswitches, and connect the cathode of the motor to the NC contact of the second microswitch. C
Connect directly to the OM contact and connect the C of the first micro switch.
2. The electric nail gun according to claim 1, further comprising an electric circuit in which the OM contact is directly connected to the NC contact of the second microswitch. (4) A safety lock is movably inserted into the nail gun main body, which locks the lever from rotating when the nail gun is moved in one direction, and allows the lever to rotate when the nail gun moves in the other direction. electric nail gun.
