Abstract
A screw releasing device with a guiding function includes a first housing, a control mechanism, and a guiding hole, the first housing defines a first receiving groove, the control mechanism is received in the first receiving groove, and includes a first cam, a second cam, and a third cam, the third cam includes a serrated member, the guiding hole receives a number of screws, and defines a first opening, when the first cam is not driven, the serrated member extends to the guiding hole via the first opening, so that the serrated member is at a supporting location and supports a bottommost screw, when the first cam is driven, the first cam drives the third cam to be not limited by the second cam and rotate, thus the serrated member is rotated to release the bottommost screw.
