In a method in an arrangement for holding or hold together objects, for example a mould (10) or mould parts (11), whereby the arrangement (1) comprises a bolt (2) and at least a nut (5) shaped in two parts (6, 7) or as two bodies, the nut (5) can take a first position or transportation position, whereby the nut (5) can be slidded in an axial direction on the bolt (2), and a second position or working position, whereby one part (6, 7) or body of the nut (5) is rotated on the bolt (2) in the course of movement in the direction towards the other part (7, 6) or body and in that respect brought into engagement with cams (3), threads or similar shown by the bolt (2). The cams (3) or similar of the bolt (2), as well as threads shown by the nut (5), the said parts (6, 7) or bodies are lacking in portions in the axial direction of the arrangement (1) or the bolt (2) and the nut (5). When the nut (5) is rotated on the bolt (2) the thread of the one part of the nut (5) will be brought out of its engagement with the cams of the bolt (2), while the thread on the other part of the nut (5) at the same time will be brought into engagement with the cams of the bolt (2), and so on. |
