Description

Technical Field

[0001] The utility model relates to the technical field of screws, in particular to a precision electronic screw. Background Art

[0002] Precision electronic screws, also known as precision screws or tiny screws, are tiny fasteners that connect product materials1. These screws have precise dimensions and spiral patterns, are usually made of metal materials, and play a key role in various electronic devices. In order to avoid the need for handheld tools to disassemble and assemble the existing screws, a power-assisting structure is usually set on the screws for the user to directly rotate the screws.

[0003] For example, an existing patent (publication number: CN213655417U) discloses a screw that is easy to disassemble and assemble. After tightening the screw, the two connecting rods are rotated to enter the one-way groove, the ends of the two auxiliary rods abut against each other, and the auxiliary rods extend into the sliding groove, so that the first spring is compressed. Under the action of its elastic force, the stability of the two connecting rods in the one-way groove is guaranteed.

[0004] However, the above-designed easy-to-disassemble screw still has some disadvantages in actual use: although the easy-to-disassemble screw does not require hand-held tools for disassembly and can conveniently hide structures such as the connecting rod and the auxiliary rod, after the auxiliary rod has been compressing the spring for a long time, the spring will inevitably experience stress relaxation, which will cause the spring to gradually lose part of its elastic force, making it impossible to eject the auxiliary rod normally and completely, making it still inconvenient to disassemble.

[0005] Therefore, we designed precision electronic screws to solve the above problems. Utility Model Content

[0010] Furthermore, a T-shaped piece is slidably arranged in the nail head, a pull rod is fixedly installed on the top of the T-shaped piece, a positioning assembly is arranged in the nail head, and the positioning assembly is connected to the T-shaped piece. When the space during installation of the precision electronic screw is limited and the pull rod cannot be extended horizontally, the pull rod can be pulled upward to make the pull rod drive the T-shaped piece to slide in the limiting cavity and release the limit with the third permanent magnet until the T-shaped piece is adsorbed by the fourth permanent magnet. The pull rod can be extended out of the nail head by an appropriate distance, and then the pull rod can be rotated to make the pull rod drive the nail head and the nail body to rotate, so as to facilitate the disassembly of the nail body and enable the convenient precision electronic screw to be used in an environment with narrow surrounding space.
