PROBLEM TO BE SOLVED: To provide a tool for retracting pawl for inserting and pulling pin in a pin inserting and pulling robot that can prevent matrix bolt or connecting pin from being damaged by the insert/pull pawl, when exchanging the pin inserting and pulling robot. SOLUTION: When a pawl for inserting and pulling pin in a pin inserting and pulling robot is stopped adjacent to matrix bolts by a breakdown, slide members 2a, 2b are mounted to a X frame of the robot to press an operating frame 4, such that a teeth wheel 5b provided on a projecting piece 4a of the X frame 4 is engaged with a pinion gear loaded on a carrier of the robot. A rotating force of a handle 12 transferred through the teeth wheel 5b rotates the pinion gear. Therefore, the pawl is retracted far away from the matrix bolt.
