The patent application (Publication Number: US20240032959A1) describes a wire feeding device designed to feed a wire in a distal end direction. The device includes a grip portion that can grip and release the wire, an elastic body that biases the grip portion towards the distal end direction, and an energizing portion that deforms the elastic body to increase the biasing force. The device can operate in two modes - continuously feeding the wire in the distal end direction or feeding the wire once according to predetermined operations. Additionally, the device features an operation portion to switch between the two modes, a deformation maintaining portion to maintain the deformation state of the elastic body, and a maintaining state change portion to disable the maintenance of the deformation state.
Furthermore, the wire feeding device includes a grip operation portion to control the state of gripping the wire, a hitting portion to come into contact with and separate from the grip portion, and a placement portion for the wire to be gripped. The grip portion consists of first and second clamping portions and a cam portion to adjust the distance between them. Additionally, the placement portion has an open and close feature to control access to the wire. An energizing operation portion is also included, which can be manually operated to increase the biasing force of the elastic body. Overall, the wire feeding device offers a versatile and efficient solution for feeding wires in different modes and configurations, enhancing usability and control in various applications.
