  As shown in FIG.1 (b), the 1st rod 11 is formed with the four cylindrical members 11a1-11a4, and accommodates the cylindrical members 11a2-11a4 with small diameter sequentially in the light large cylindrical member 11a, These cylindrical members 11a1 to 11a4 are connected to each other. When the first rod 11 is extended, the small cylindrical member 11a2 is protruded from the large cylindrical member 11a, and the cylindrical member 11a3 is similarly protruded from the cylindrical member 11a2. The cylindrical member 11a4 is protruded from the member 11a3. On the other hand, when the first rod 11 is reduced, the small cylindrical member 11a4 is accommodated in the large cylindrical member 11b3. Similarly, the cylindrical member 11a3 is accommodated in the cylindrical member 11a2, and the cylindrical member The member 11a2 is accommodated in the cylindrical member 11a1.

  Similarly, the second rod 12 is formed of four cylindrical members 12a1 to 12a4. The cylindrical members 12a2 to 12a4 having smaller diameters are sequentially stored in the lighter large cylindrical member 12a, and these cylindrical members 12a1 to 12a1 are accommodated. 12a4 is connected. When the second rod 12 is extended, the small cylindrical member 12a2 is projected from the large cylindrical member 12a, and the cylindrical member 12a3 is similarly projected from the cylindrical member 12a2 to form a cylindrical shape. The cylindrical member 12a4 is protruded from the member 12a3. On the other hand, when the second rod 12 is reduced, the cylindrical member 12a4 having a small warp is accommodated in the cylindrical member 12b3 having a large warp.
