A screw feeding device of a screw gun includes a guiding cover assembled at the bottom of a screw gun and a base slidably assembled inside of the guiding cover. Inside of the base, a screw feeding wheel and an oscillating member are assembled in the same axle. The oscillating member includes an off-center guiding portion slidably assembled to the guiding slot of the guiding cover. The guiding portion is guided by the guiding slot and drives the oscillating member to move. A plurality of locking grooves is provided surrounding the axle center of the screw feeding wheel. At least one locking claw bears the elastic force to be pivotally assembled to the oscillating member. The locking claw includes an off-center pushing portion. The locking claw moves accompanying with the oscillating member, drives the pushing portion to elastically contact the locking groove and therefore, drives the screw feeding wheel to rotate. The locking claw also drives the pushing portion to be separated from the locking groove and discharges the screw feeding wheel. |
