A detachable instrument that is used for screw riveting and welding torsion to test

The utility model provides a detachable instrument that is used for screw riveting and welding torsion to test, it includes screw sleeve and supporting bolt, screw sleeve is last to be equipped with one and to link up screw sleeve's screw hole, the inside of screw hole is provided with the screw thread, supporting bolt screw thread is screwed up in the one end of screw hole. The utility model discloses a detachable instrument that is used for screw riveting and welding torsion to test can satisfy experimental requirement to can the implementation tool dismantle repeatedly usable. The simple structure of detachable instrument, and the practicality is strong, need not to carry out welding process before the experiment, and work efficiency improves greatly. And, requiring and rivet or weld under the unbroken condition at torsion up to standard, the part need not not be scrapped. 本实用新型提供了种用于螺钉铆接和焊接扭力实验的可拆卸式工具，其包括螺纹套筒和配套螺栓，所述螺纹套筒上设有个贯通所述螺纹套筒的螺纹孔，所述螺纹孔的内部设置有螺纹，所述配套螺栓螺纹拧紧在所述螺纹孔的端内。本实用新型用于螺钉铆接和焊接扭力实验的可拆卸式工具可以满足试验的要求，
