The invention discloses a novel fastener and relates to a fastener. The novel fastener comprises a handle part (1), a screw head (2), a bolt (3), a thread (4) and a nut, one end of the screw head (2) is connected with the handle part (1), the other end of the screw head (2) is connected with the bolt (3) provided with the thread (4), and the bolt (3) is connected with the nut (5) through the thread (4). The novel fastener is simple in structure, novel and unique in design, convenient to mount and use and free of slipping during use. The novel fastener which can be not only connected in a manual screwing way but screwed by a screw driver is good in fastening effect, and cost is saved.
Description
Technical field: [0001] The invention relates to a fastener, in particular to a novel fastener. Background technique: [0002] Fasteners are a general term for a class of mechanical parts used to fasten two or more parts into a whole. They are used in various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, All kinds of fasteners can be seen on instruments, meters and supplies. There are many types and specifications of existing fasteners, and special tightening tools are required during use, such as screwdrivers or wrenches to tighten or loosen the fasteners. The screw heads of general screw fasteners are provided with cross-shaped or The straight groove, when using a screwdriver to tighten, it is easy to grind the cross head or the straight head, and it is also easy to slip the thread, resulting in cost waste. Invention content: [0003] The purpose of this invention is to provide a new type of fastener, which is simple in structu...
