Summary of information:We have more than ten years of production experience in the screw industry, the main products are: iron self-locking ant...

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

The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to overcome the above shortcomings and provide a limit screw. The technical scheme of Guangdong Yueluo Hardware Industry Co., Ltd. is realized in the following way. Its structure is composed of screws, hexagonal copper posts and limit necks. The left end of the limit neck is open, the hexagonal copper column is communicated with the inside of the limit neck, and the inside is provided with screw threads. The design length of the screw thread in the hexagonal copper column is 1/3-2/3 of its own length. The advantages of Guangdong Yueluo Hardware Industry Co., Ltd. are (12), which can effectively prevent the problem of poor memory contact caused by the increase in the deformation of the motherboard due to the warping and deformation of the motherboard during installation and fixing, and can effectively control the deformation. effect.

However, although the above-mentioned screw belt (2) can achieve the expected effect, it is also found in its actual implementation. Although this structure has multiple grooves on both sides of the main body for the driving and turning of the locking screw tool, However, the groove is only used for driving the screw belt drive, and since the screw will swing on the screw belt, it is impossible to stably align the screw on the screw belt with the point where the screw is to be set. , which leads to great inconvenience in operation and use, and also affects the efficiency of screw and screw installation, so that there is still room for improvement in the overall structural composition.

The slotted nut mainly refers to the hexagonal slotted nut, that is, the slot is machined above the hexagonal nut. It is used in conjunction with screw bolts with holes and cotter pins to prevent the relative rotation of the bolts and nuts, see GB6178 ~ 6181 and so on.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: high-strength screws, spacer standoffs, four-jaw nuts for furniture, blind hole rivet standoffs and other products, we can provide you with suitable products Your fastener solution.
