PROBLEM TO BE SOLVED: To smoothly draw out a penetration rod while reducing labor burden of operators for the drawing work for the rod. SOLUTION: This device is provided with a slide block 13 which can be linearly and reciprocally slided by the drive of a hydraulic cylinder and a rod holder 20 disposed to be transferable together with the slide block 13. The rod holder 20 is provided with links 22, 23 constituted to reciprocate integrally with the slide block 13, a plurality of holding plates 25,... rotatably fitted to respective links and provided with guide holes in which an penetration rod can be inserted, and a fitting plate 26 formed so that the holding plates 25 simultaneously rotate and the guide holes are lined up on a coaxial line at a specified position by alternately superimposing the holding plates 25 connected to the links 22 and the holding plates 25 connected to the links 23 and rotatably connecting them together.
