摘要： The present invention discloses a connecting structure, a connecting method and an article containing the connecting structure. The connecting structure includes a fastener, a first connecting member adjacent to the trailing end of the fastener and a second connecting member away from the trailing end of the fastener. The second connecting member is provided with a threaded connecting hole, which in the axial direction thereof is provided with thread matching with the form of thread of the fastener and having a central angle of at least 180 degrees. The first connecting member is provided with a connecting hole, and the fastener connects the two connecting members through the threaded connecting hole and the connecting hole. The connecting method achieves quick connecting with the connecting hole of the first connecting member by preloading the fastener to the threaded connecting hole, without being affected by the assembly space. The connecting structure and the connecting method can be used in a variety of articles. The thickness of the threaded connecting hole is equal to the pitch of the fastener. The form of thread of the threaded connecting hole is fitted with the thread of the fastener by only one turn, which during processing can be made directly in the form of stamping, resulting in a simple processing and improving the processing efficiency.

摘要： The present invention discloses a stud sensor, which is used for detecting the object hidden behind a surface, including a first capacitor plate, a second capacitor plate, a first detection circuit coupled to the first capacitor plate, a second detection circuit coupled to the second capacitor plate and a micro control unit. The first detection circuit processes the voltage signal corresponding to the first capacitance of the first capacitor plate and outputs a first voltage signal to the micro control unit. The second detection circuit processes the voltage signal corresponding to the second capacitance of the second capacitor plate and outputs a second voltage signal to the micro control unit. The micro control unit compares the first voltage signal and the second voltage signal to determine the position information including the central position of the object. The stud sensor of the invention also includes an output module to show the position information of the object, an input module to input instructions to the micro control unit.

摘要： Disclosed is a manual tool capable of unfolding only one work accessory. The conventional manual tools may bring hidden risk to safety with more than two work accessories that may be unfolded simultaneously. According to the present invention, an associated accessory is arranged for a working state of a first work accessory and a second work accessory to transform from a folding state to an unfolding state; in the folding state where the first work accessory and the second work accessory are both folded, the associated accessory does not prevent any work accessory from unfolding; while in the unfolding state where one of the two work accessories is unfolded and the other one is folded, the associated accessory prevents the other one from unfolding, so as to ensure that only one work accessory can be unfolded during use, and if the unfolded work accessory is left unfolded, the other work accessory cannot be unfolded, thereby eliminating the safety risk caused by unfolding multiple work accessories at the same time.
