Service HotlineThe combination screw is actually a kind of screw, but it is special. It is generally a three-component or a two-component, but at least it can be called a combination screw. The main difference from ordinary screws is that they are equipped with one more spring washer or one more flat washer than ordinary screws. This is the main difference between the appearance of combination screws and ordinary screws. In addition to the obvious difference in appearance between combination screws and ordinary screws, the main difference is the difference in mechanical properties and uses. The combination screw is a three-component or two-component with a flat washer. Of course, it is equipped with a flat washer by an ordinary screw. When the spring flat pad is attached, the spring flat pad will not fall off. Fastened to form an assembly. In terms of mechanical performance, the combination screw is composed of three accessories, and in terms of performance, three fasteners must be used together. The mechanical properties of the combined screw are stronger when used. More convenient, the biggest advantage of the combined screw is that the production line can be operated conveniently and quickly, and the work efficiency can be improved. The difference between the use of combination screws and ordinary screws is mainly in the breadth of use. The use of ordinary screws is more extensive than that of combination screws. Basically, ordinary screws are used in industrial products, and combination screws! It is only useful for specific product materials. When the screw needs to be used with a spring washer and a flat washer, the combination screw can be used at this time.
The technical problem to be solved by Yueluo is to provide a medical self-locking screw, which can fix the inner screw inside the outer screw, expand the outer screw head through the thimble on the inner screw, and use the outer cone on the inner screw. The body expands, compresses the surrounding bone, and achieves a double locking effect through the self-locking between the internal and external screws; it can hook the surrounding fixed parts when the anti-retraction ring is retracted to achieve the anti-regression effect; effectively prevent false implantation. After a long period of service, the looseness, fretting and other adverse reactions of the body are used to solve the defects caused by the existing technology.

As a commonly used data communication device, connectors are widely used in computers and TVs. Because common connectors such as D-SUB and DVI are composed of a male seat and a female seat, the iron shell of the male seat and the female seat is The corresponding position is provided with holes, the holes of the male seat are connected with rivets, and the holes of the female seat are correspondingly provided with screws for fixing. After the male seat and the female seat are connected, tighten the screws so that the male seat and the female seat are tightly connected together. When assembling on a computer or a TV, the rivet has a fixed assembly direction, and the fixation of the rivet direction is very important for assembly. However, there is no anti-rotation device on the iron shell hole connected with the rivet on the existing connector, and the rivet cannot be positioned during the assembly process, and it is easy to rotate and dislocate. production efficiency.
