M270163 IV. Creation Instructions α) [Technical Field to which the New Type belongs] This creation provides an improved structure of a retractable cable retractor, a cable retractor structure capable of automatically springing back and retracting. Rewinding, and can greatly simplify the overall structure of the retractor. '; [Previous technology] With the advancement of science and technology and the development of the industry, electronic equipment (such as · Π: 2 Γ camera, card reader, etc.) has been widely used. All of them need to be connected with each other to achieve the purpose of communicating with their electrical signals. In order to avoid tangling and messing over communication cables, or to be too short to be able to make it over again, related industries have developed various types of winding; = User: Users: The needs of different consumer markets [However, these retractors are still incomplete, so they are committed to improving the research topics mentioned above. ^ This is the creative knowledge The cable retractor structure mainly includes a shape spring and a cable group. The volute spring in # is fixed to the coil:: 绕 Winding: It has a coil _ ^, and one of them is connected with a connector, respectively. It can be connected with various types, in which the f-seat of the connection plate $ of the cable group in the housing is connected with different types of design. It can be made on the winding wire d, that is, there are multiple loops, and the other end is provided with multiple conductive The end of the shrapnel is provided with the last number of conductive and can still maintain the state of electrical connection. &Amp; steel balls for rotation Process However, due to the many structural time of its constituent elements, it is easier to cause friction loss between the components and you not only increase the assembly # 'and make it less practical than M270163 on page 5. In addition, the internal, when turning phenomenon, and Need to work on the retractor; in addition, the cable group is pulled out to retain the proper work and maintenance. The creator has the feeling that it can be modified based on the above-mentioned problems. The cable coil and the cable group are pulled into the shell and applied. Most of the problems will be caused by the fixed length of the vortex. When the problem is solved, the spirit of the essence of the creation of the receiver will be taken up by the body, the cable will be dismantled, and the spring will be shaped outside. ; Interfering with inconveniences and subordinate points, Nai Qian, finally mentioning and creating instructions (2) Economical and greatly reduced a closed shell to make the cable 1 line better, and the cable is arranged in the structure during maintenance. Cable state, so that users who are not able to use it, the experience of this book, and practical use, rational and effective improvement [new content] The structure of this creation is improved, and its dynamic positioning gears simplify the retractor. To improve the structure of the receiver, a housing, a convex shaft, and a reel are pivotally connected to the housing, and a spiral elastic cable set is installed in the process, which can not help but lock the cable without disassembling the cable. It does not have a fixed elasticity and is so tight. It will be researched for many years in the industry and cooperate with a design. The main purpose is to provide a retractable cable retractor that is located between the reel and the positioning assembly. There are mutual calls, and the talent group can be easily stretched and retracted, and can have a large overall structure. ^ The above purpose 'this creative system provides a telescopic coiled wire coil' whose structure includes: it is formed with an accommodation Space, one end of the accommodation space is provided with a wire groove; one is provided in the accommodation space of the housing, and one end of the reel is provided with an internal gear with the convex shaft of the housing; Inside the reel, one end of the spiral spring is connected
