[0023] When inspecting the nut, align the inner side of the nut tube 2 with the gasket 7. At the same time, align the slot 10 on the bottom of the nut tube 2 with the block 8 on the outside of the gasket 7. Then, place the nut tube 2 on the gasket 7 so that the block 8 is fixedly engaged with the slot 10 on the bottom of the nut tube 2, thereby limiting the axial rotation of the nut tube 2. Insert the insertion rod 5 into the through hole 4 on the fixing block 3. The insertion rod 5 passes through the inside of the through hole 4 and is fixedly engaged with the slot 9 on the nut tube 2, thereby limiting the axial movement of the nut tube 2.

Insert the insertion rod 5 into the through hole 4 on the fixing block 3. The insertion rod 5 passes through the through hole 4 and is engaged and fixed with the slot 9 on the nut tube 2, thereby limiting the axial movement of the nut tube 2. The nut tube 2 is detected by an external screw. Through the above process, the nut can be quickly positioned and fixed, which solves the problem of the existing adjustable nut detection fixture. The nut is fixed by clamps in multiple directions. Each clamp needs to be manually adjusted. At the same time, the position of the nut needs to be controlled, which is time-consuming and labor-intensive, and reduces labor efficiency.

Then, the nut tube 2 is placed on the cushion block 7, so that the card block 8 is fixedly engaged with the card slot 10 on the bottom surface of the nut tube 2, thereby limiting the axial rotation of the nut tube 2, and the insertion rod 5 is inserted into the through hole 4 on the fixing block 3. The insertion rod 5 passes through the inside of the through hole 4 and is fixedly engaged with the slot 9 on the nut tube 2, thereby limiting the axial movement of the nut tube 2. The nut tube 2 is detected by the external screw, and then the insertion rod 5 is withdrawn to rotate the nut tube 2 in reverse. Exactly one hundred and eighty degrees, swap the positions of the two slots 10 so that the original slot 10 on the top surface is moved to the position of the bottom slot 10, then align the inner side of the nut tube 2 with the gasket 7, and at the same time, align the slot 10 on the bottom surface of the nut tube 2 with the block 8 on the outside of the gasket 7, then place the nut tube 2 on the gasket 7, so that the block 8 is engaged and fixed with the slot 10 on the bottom surface of the nut tube 2, thereby limiting the axial rotation of the nut tube 2, insert the rod 5 into the through hole 4 on the fixing block 3, and the rod 5 passes through the inside of the through hole 4 to be engaged and fixed with the slot 9 on the nut tube 2, thereby limiting the axial movement of the nut tube 2, and the nut tube 2 is detected by the external screw.
