Abstract
A power tool includes an ejection mechanism configured to eject an end of a fastener. The ejection mechanism includes an ejection rod that is actuated by a motor of a power tool to move from a first position to a second position to eject the end of the fastener. Following ejection of the end of the fastener, the ejection rod is returned to the first position by a return spring.
Claims20
An ejection mechanism for a power tool, the ejection mechanism comprising:
- an ejection rod having a threaded shaft;
- a cam plate that is selectively actuated between a first position and a second position;
- and
- a pawl engaged with the cam plate, the pawl being disengaged from the threaded shaft of the ejection rod when the cam plate is in the first position and being engaged with the threaded shaft of the ejection rod when the cam plate is in the second position to cause the ejection rod to axially actuate from a first axial position to a second axial position.
1 more element
An ejection mechanism for a power tool, the ejection mechanism comprising:
- an ejection rod including a first cam face;
- a second cam face coupled to a one-way clutch to permit unidirectional rotation of the second cam face so that rotation of the ejection rod in a first direction rotates both the first cam face and the second cam face together and rotation of the ejection rod in a second direction rotates the first cam face and locks rotation of the second cam face to cause the ejection rod to actuate;
- and
- a biasing element that biases the first cam face into engagement with the second cam face.
1 more element
A power tool, comprising:
- an electric motor;
- an ejection mechanism including:
- an ejection rod having threaded shaft with a first end opposite a second end, and
- a shuttle moveable between a first position and a second position, the shuttle defining a cutout having a threaded portion;
- and
- an actuator that moves the shuttle between the first position, where the threaded portion of the cutout is disengaged from the threaded shaft, and the second position, where the threaded portion of the cutout is engaged with the threaded shaft.
