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 uses a locking screw to achieve the proposed object, which has the features of claim 3 . 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.
Stud, also known as double-ended screw or double-ended stud. It is used to connect the fixed link function of the machine. The stud bolt has threads at both ends, and the screw in the middle is thick or thin. Generally used in mining machinery, bridges, automobiles, motorcycles, boiler steel structures, pendant towers, long-span steel structures and large buildings.
The pin body of the cylindrical pin is generally provided with one or two fixing holes for inserting the split pin to realize the positioning of the pin body. The fixing hole is drilled by a drilling machine, because the drill bit is easy to slip when drilling on the cylinder, and it needs to be processed by tooling. When machining the fixed holes on the cylindrical pins, because the cylindrical pins have many specifications and different thicknesses, even the positions of the holes required to be machined on the same cylindrical pin body are not the same, resulting in various drilling tooling for the pin body, resulting in processing costs. High, on-site management is difficult.
In order to achieve the above purpose, the technical scheme adopted by the screw in Yueluo Company is as follows.
