<p>PROBLEM TO BE SOLVED: To provide a drawing tool which is hardly bent and can be operated easily by increasing strength of the tool as much as possible, by gradually increasing width of ribbon-like steel which expands and contracts a telescopic rod from the front-end rod side of the telescopic rod. SOLUTION: A drawing tool 1 is composed of a telescopic rod 3 installed to the main body 2 of the tool 1, ribbon-like steel 4 which is passed through the hollow section of the rod 3 for expanding and contracting the rod 3, and a drawing-out and pulling-back device which is incorporated in the main body 2 and draws out and pulls back the steel 4. The telescopic rod 3 is constituted by putting a plurality of rod-like bodies in and on each other like a shaking-out type fishing rod, and composed of a front end rod 31 which is positioned to the front end when the rod 3 is extended, two intermediate rods 32, and a base-section rod 33 fixed to the main body 2. Both side sections of the ribbon- like steel 4 are formed in step-like states so that the width of the steel 4 may gradually become narrower toward the front end. Usually, the rods constituting the telescopic rod 3 are engaged with and fixed to each other by friction.</p> |
