Japanese Patent JP7122196
Kind Code:
B2
Abstract:
To provide a rod-shaped core feeding tool whose core does not sink when writing, and which can rotate the core without causing a malfunction at the user's arbitrary timing while keeping a writing position.SOLUTION: The rod-shaped core feeding tool comprises an operating body 9 disposed on the outer side of a shaft body 6 so as to be movable back and forth. A rotor 24 is provided in the shaft body 6 for converting the relative movement backward of the operating body 9 into a rotational movement. A cylindrical body 14 which is non-rotatably and slidably engaged is provided inside the rotor 24. The cylindrical body 14 is configured to slide back and forth in conjunction with the operating body 9. A stopper 26 for restricting the retraction of the cylindrical body 14 is disposed behind the cylindrical body 14, and the stopper 26 is formed so as to be able to switch whether or not the cylindrical body 14 can be retracted as the operating body 9 moves backward. A chuck 12 is formed so as to be rotatable with respect to the shaft body 6, and the operating body 9 is formed so that when it moves backward relative to the shaft body 6, the rotor 24 rotates.SELECTED DRAWING: Figure 1
