Claims

[Claims for Utility Model Registration] It has two plate parts that are bent and arranged almost parallel to each other, and on one edge side of these plate parts, there are two groove parts with a width slightly larger than the shaft diameter of the bolt, spaced apart from each other. A retaining plate with a notch formed in the retaining plate, and a hook-shaped retaining part that cooperates with the groove of the retaining plate to clamp and hold the shaft of the bolt that is inserted into the groove, are respectively provided at the distal end, and the intermediate part is comprises a pair of handle members pivotably supported on a holding plate between the two plate parts, and a biasing member that always biases the handle members in an open direction, and the holding part is configured to control the handle member. When the handle member is open, it is in a position that does not face the groove, and when the handle member is closed against the biasing force of the biasing member, it is in a position that faces the groove, causing the shaft of the bolt to cooperate with the groove. A bolt holder characterized in that it is configured to clamp and hold the bolt.
