Generally speaking, there are two main sources of lighting for people, the first is natural light in the environment, and the second is lighting devices (such as ceiling lamps, table lamps, etc.), which can provide the required lighting for the surrounding environment, thereby improving the Work or study efficiency can also avoid or reduce the chance of accidents. In addition to the need for lighting, some light has special effects. For example, the thermal energy of infrared light can improve blood circulation, relieve symptoms such as muscle stiffness and pain; deep ultraviolet (UVC) light can destroy the deoxyribose sugar in bacteria and viruses. Nucleic acid (DNA) and ribonucleic acid (RNA) are bonded to achieve a physical disinfection mechanism; therefore, as the technology of optical modules (such as light-emitting diodes (LED)) becomes more and more sophisticated, the functions of lamps and lanterns also become more and more Diversification, not just limited to a single lighting effect.

Take the ultraviolet germicidal lamp as an example. Due to the recent outbreak of the novel coronavirus pneumonia (COVID-19), in addition to the use of hand sanitizer, disinfectant, alcohol cotton and other disinfection products, hand-held ultraviolet germicidal lamps are also widely used. The aforesaid ultraviolet germicidal lamp has a lightweight appearance, which is convenient for people to carry around, and as long as the lamp is turned on to illuminate the palm or objects, it can achieve the effect of eliminating bacteria and viruses, so as to alleviate people's worries about the spread of the epidemic. However, some hand-held ultraviolet germicidal lamps currently use plastic materials as the shell of the lamp device, which will cause difficulty in heat dissipation.

However, since the pivot ring 23 and the plastic pivot shaft 25 may not be able to maintain coaxial rotation, the user turns the plastic pivot shaft 25 over. During the process of the light-emitting part 12, it is easy to cause difficult rotation, poor rotation smoothness, or suddenly too fast rotation (due to the slippage between the pivot ring 23 and the plastic pivot shaft 25), which causes inconvenience in use and affects the User experience;

(2) During long-term use, the plastic pivot shaft 25 may deviate from the predetermined assembly position left and right. Since the pivot ring 23 is sleeved on the plastic pivot shaft 25 and contacts with each other, when the When the plastic pivot shaft 25 deviates from the lower right direction or the upper left direction as shown in FIG. 3 , the pivot ring 23 will also move along with it, resulting in the opposite surfaces of the pivot ring 23 and the hollow frames 211 . A lot of fines are generated due to friction, and the aforementioned fines will accumulate between the pivot ring 23, the plastic pivot shaft 25 and the hollow frame 211. Over time, the light-emitting portion 12 will be difficult to rotate or unable to rotate, etc. In some cases, even under the circumstance that the user turns over with great force, the components inside the pivot structure 2 may be deformed or damaged.

To sum up, in order to solve the aforementioned problems, the present invention specially provides the positioning member 27, as shown in FIG. After protruding the inner wall of the first through hole 210 of one of the hollow frame bodies 211, the plastic pivot shaft 25 is inserted (eg, screwed into the opening 253 of the plastic shaft element 251), so that the Plastic pivot shaft 25, so that the plastic pivot shaft 25 cannot rotate with the pivot ring 23 and cannot deviate from the predetermined assembly position, so as to avoid the aforementioned uneasy rotation, sudden too fast rotation or generation of a lot of fines to cause component deformation or damage problem. In this embodiment, please refer to FIG. 4 , when the plastic pivot shaft 25 includes two plastic shaft elements 251 and 252 , the length of the plastic shaft element 251 extending into the pivot ring 23 is longer, The length of the plastic shaft element 252 extending into the pivot ring 23 is relatively short. Therefore, when the pivot ring 23 rotates, the contact area between the plastic shaft element 251 and the plastic shaft element 251 is larger, and the plastic shaft element 251 is easier to drive. Therefore, as long as the positioning member 27 fixes the plastic shaft element 251, the aforementioned problem can be solved. However, in other embodiments of the present invention, the number and position of the positioning member 27 can be adjusted according to the requirements of the product, as long as It is sufficient to solve the aforementioned problems.
