Service HotlineGuangdong Yueluo Hardware Industry Co., Ltd. was founded in 1998, and the factory was established in Feilong Industrial Zone, Xiaolan Town, Zhongshan City, Guangdong Province, with an investment of 10 million yuan. The main production is a variety of national standard, non-standard, British, American, metric screws. Mainly include: special screws for the electronics industry (machine screws, self-tapping screws, special screws): nuts (general nuts, flange nuts, external teeth nuts): Washers (external teeth, internal teeth, flat springs) Gaskets, etc.); lathes (precision automatic lathe parts, connecting parts, embedded parts, fasteners, decorative parts, etc.).
The advantage of wood screws is that the consolidation ability is stronger than that of nails, and they can be removed and replaced, which is more convenient to use without damaging the wood surface. This is a kind of nail specially designed for wood, and after entering the wood, it will be embedded in it very firmly. If the wood is not damaged, it is impossible to pull it out, and even if it is pulled out forcibly, it will bring out the nearby wood. Another point to note is that the wood screws must be screwed in with a screwdriver. Never knock them in with a hammer, as it will damage the surrounding wood. A screwdriver is a tool for loading and unloading wood screws. The shape matches the groove shape of the wood screw head, and there are two types: one-word and cross-shaped. In addition, there is a special screwdriver installed on the bow drill, which is suitable for loading and unloading large wood screws. Convenient and labor-saving. [2]
In the prior art, the electric screwdrivers in the automatic locking screw machines all adopt the suction method to absorb the screws. Such a structure is relatively complicated, and the design of the air circuit needs to be considered, and the phenomenon of material jamming is prone to occur, and it cannot be carried out due to the reason of the air circuit. Deep hole locking screws cause great trouble to users.
The side wall of the bolt hole is threaded, and the top of the nut is provided with several flattening notches. According to the locking nut of the preferred embodiment of Guangdong Yueluo Hardware Industry Co., Ltd., the number of flattening notches is three. Due to the above features, the three flattening notches can be used as the focal point of the tightening tool, and the
rivet is a nail-shaped object with a cap on one end: in riveting, the riveted parts are connected by their own deformation or interference. There are many types of rivets, and they are informal. Commonly used are semi-circular head, flat head, semi-hollow rivet, solid rivet, countersunk head rivet, blind rivet, hollow rivet, which usually use their own deformation to connect the riveted parts. Generally, cold riveting is used for those smaller than 8 mm, and hot riveting is used for larger ones. But there are exceptions, such as the nameplate on the three-ring lock, which is riveted by the interference between the rivet and the lock body hole. In addition, there are paired rivets, which are special. Divided into two parts, the thicker section of the rod with a cap has a hole in the center, and the other section of the rod with a cap is an interference fit. When riveting, drive the thin rod into the thick rod. Most of the existing rivets are connected by overall deformation to achieve mutual cooperation. In the ultra-fine-pitch display screen, the rivets used to fix the ultra-fine-pitch display screen have a slender diameter. If they are fixed by overall deformation, they are prone to bending and breaking. and other phenomena, the tightening effect is not good or there is no tightening effect, which damages the components, increases the cost, and wastes time and resources.
