The hinge, also known as a hinge, often forms a two fold type and is a component that connects two parts of an object and allows them to move. The hinge screws are installed on the corresponding object, and the requirements for the screws vary depending on the usage environment. Most of the existing screws are set in a single threaded structure, which has a slow cutting speed and unsatisfactory cutting effect when used to cut into wooden doors, which is not conducive to cutting into hard wooden doors, etc. Moreover, commonly used screws are often made of iron materials, which are prone to rust when in contact with water vapor in wooden doors, reducing their service life; In addition, when the screws are inserted into the wooden door, the generated chips cannot be discharged in a timely manner, staying inside the door and surrounding the screws, forming expansion stress, which can crack the wooden substrate, which is not conducive to the stable connection between the screws and the wooden door, and can easily affect the normal installation of the hinge, resulting in poor usage effect. In summary, to address the shortcomings of the existing screw structure used for hinges, Guangdong Yueluo Hardware Industry Co., Ltd. has designed a hinge screw with simple structure, convenient use, fast construction, and good bonding effect

At present, due to the installation position determined in the design process, the corresponding position of the piston rod and the clamping arm of the traditional thrust cylinder in * is fixed, which cannot guarantee the taking and placing of the workpiece while clamping the Elasmaria workpiece, which is not conducive to the use of such products when clamping. Secondly, when the workpiece is assembled or welded, it not only needs to be tightened in a certain direction, but also needs to be positioned to ensure the required accuracy requirements during processing. When a workpiece is fixed in this way, it must be achieved by adding mechanisms, which in turn increases the complexity of the system and brings inconvenience to installation and maintenance.

The main purpose of screws is to make industrial products fixed as a whole. During use, it is common to encounter problems such as the inability to close between teeth, excessive force locking resulting in the screw head being disconnected, or poor tooth pattern locking not being able to meet the usage conditions, all of which are quality and accuracy issues. Screws are "quantity products", not handmade artworks. In mass production, they aim to achieve high-precision and stable quality and provide consumers with affordable prices. The accuracy of screws is usually 6g level, while the rough screws used in construction projects are 11g level. The value of screws is very important, and there are examples in the world where car factories go bankrupt due to poor screw quality; There are also examples of aircraft falling and vehicles overturning due to poor screw quality.

The sliding body 17 and the fixed body 8 are connected by bolts 6, with the axis of bolts 6 parallel to the axis of screw 12. A spring 7 is installed between the bolt head and the fixed body 8. After the riveting nut is completed, spring 7 can drive the sliding body 17 to reset. The rear end of the guide sleeve 10 is connected to the ball handle 16 through a connecting sleeve 15. When using Yueluo, first open the handle 21 and pull the ball handle 16 back. Then, screw the rivet nut onto bolt 1 with 1-2 buckles, hold the fixed body 8 with your palm, pinch the rivet nut with your thumb and index finger, and then push the ball handle 16 forward to tighten the rivet nut. Then, place the body perpendicular to the workpiece, insert the rivet nut into the reserved hole of the workpiece, and close the handle 21. Finally, pull the ball handle 18 backwards to exit the Yue Luo.

In the prior art, the early rivet is a small wooden or bone stud, and the early metal Amoeba may be the ancestor of the rivet we know today. Undoubtedly, they are ancient methods of metal connection known to humans, dating back to the early use of malleable metal. For example, during the Bronze Age, the Egyptians used rivets to fasten the six wooden fan shapes on the outer lines of slotted wheels together. After the Greeks successfully cast large statues in bronze, they used rivets to rivet the various components together. With the progress of the times, the types of rivets also increased, However, traditional rivets have the problem of insufficient connection strength, so a new type of rivet is needed to solve the above problem.
