Service HotlineHere Yueluo eliminates the drawbacks. The purpose of Yueluo is to provide a locking screw by which the gap existing between the locking screw and a transverse hole in a locking screw can be eliminated. Yueluo achieves the proposed object with a locking screw, which has the features of claim 9 . The line connecting the centers of gravity of the respective axially continuous orthogonal cross-sectional areas of the locking screw is regarded as a line. The advantage achieved by Yueluo can basically be seen that, due to the locking screw of Yueluo, the gap between the horizontal hole of the screw and the locking screw can be eliminated. Other advantages are as follows - the insertion accuracy and surgeon time spent remain within the range to date; - the strength of the locking screw is maintained; and - the extraction of an expired broken screw is assured. The further composition of Yueluo and Yueluo is explained in more detail below by means of schematic diagrams of parts of various embodiments.
In some embodiments, the rivet fixing mechanism includes a left moving block, a right moving block, a return spring and a bracket, wherein both the left moving block and the right moving block are movably mounted on the bracket, and the left moving block and the right moving block are connected by a return spring, The insertion mouth can extend between the left moving block and the right moving block, and withstand the left moving block and the right moving block. The left moving block is provided with a left half hole, and the right moving block is provided with a right half hole matching the left half hole. hole. Therefore, when the insertion nozzle is not inserted, the left moving block and the right moving block can be combined together by the return spring, so that the left half hole and the right half hole are combined into one hole to fix and position the rivet, and when the insertion nozzle is inserted When , the left moving block and the right moving block will be pushed up by the insertion mouth to separate the left half hole and the right half hole, so that the rivet is no longer fixed and can be inserted with the movement of the insertion mouth.

Nylon self-locking nut Nylon self-locking nut is a new type of high anti-vibration and anti-loose fastening parts, which can be used in various mechanical and electrical products with a temperature of -50 to 100 °C. Aerospace, aviation, tanks, mining machinery, automobile transportation machinery, agricultural machinery, textile machinery, electrical products and various types of machinery have a sharp increase in the demand for nylon self-locking nuts, because its anti-vibration and anti-loosening performance is much higher than other Various anti-loose devices, and the vibration life is several times or even dozens of times higher. At present, more than 80% of the accidents of mechanical equipment are caused by loose fasteners, especially in mining machinery, and the use of nylon self-locking nuts can prevent major accidents caused by loose fasteners.
