Here 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 5 . 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.
When the iron pot is manufactured, the iron head is connected to the iron pot body through rivets, and then the pot handle is set through the iron head, and the iron head connects the pot handle and the iron pot body together. However, when the iron head is installed, the position may be inaccurate. At this time, it is necessary to remove the rivet and reinstall the iron head. At present, the removal of rivets is completely done manually, that is, workers use screwdrivers to unscrew the rivets, which is difficult to remove, wastes a lot of manpower, and has low work efficiency, thereby reducing production efficiency.
