With the above structure and composition design, the following is a description of the operation of the present invention. Please refer to the third to sixth E drawings, which are schematic diagrams of the implementation of the preferred embodiment of the present invention. As can be clearly seen from the figure, the first plug terminal group 17 and the second plug terminal group 18 of the safety plug adapter shown are respectively defined by a European circular plug terminal and an American flat plug terminal. For example, in the preferred embodiment of the present invention, the first plug terminal group 17 and the second plug terminal group 18 have different distances between the two plug terminal groups, and the European round plug terminal has a wider pitch A, and the American flat type The pitch B of the plug-in terminal is short, so that the American flat-type plug-in terminal can be disposed within the distance A of the European-style circular plug terminal, so that the two can be opened without interfering with each other; in the folded state, the first plug The terminal group 17 and the second plug terminal group 18 are folded together on one side of the base 11 and do not protrude beyond the base 11, thereby reducing the space occupied by the safety plug adapter and not scratching due to protrusion. Human body or article; in the state of use, the first plug terminal can be selected The group 17 or the second plug terminal group 18 is correspondingly plugged into the mating socket so that the plug can be obtained from a socket of a different specification; the invention is not limited to the use of European style The plug-in terminal can be easily picked up by the operator when the operator takes the safety plug adapter. In addition, in response to safety factors and different specifications of plugs in various countries, many countries have sockets with grounding design and grounding holes in the sockets, such as the United Kingdom, so a grounding terminal group 23 is provided on the safety plug adapter. The grounding terminal group 23 is pivotally disposed on the base 11 and is folded into the base 11 in a folded state without protruding from the surface of the base 11 and is rotatably erected on the base 11 in a state of use, and can be inserted into the socket. In the corresponding grounding hole. Furthermore, the extending portion 171 pivoted through the first plug terminal group 17 and the rotating slot 181 defined on the base 11 allow the first plug terminal group 17 to be inserted into the jack having a larger area. The second plug terminal group 18 can be picked up and protruded from the surface of the base 11 via the yoke assembly, and the second plug terminal group 18 can be simultaneously displaced by the rotation groove 181. As described above, the grounding hole of the British socket is provided with safety measures. In the case where the ground terminal group 23 is not inserted, the corresponding plug terminal cannot obtain a power source from the British socket, and the present invention utilizes the ground terminal provided with the above. Group 23, so even if the first plug terminal group 17 of the safety plug adapter is a European-style circular plug terminal, it is only necessary to erect the ground terminal group 23, so that the European-style circular plug terminal is made of a British socket. Get electricity in. The ground terminal group 23 can be made of an insulating material or a conductive material, and does not necessarily have to have a conductive grounding function, and only needs to open the security measures of the British socket. Allow the plug-in terminal to be plugged into the socket to take power. When the operator wants to insert a jack with a large insertion area, the auxiliary component 19 is designed to facilitate the practical purpose of the operator to insert the jack. Moreover, the present invention is further provided with a connection hole 29 conforming to the USB plug specification for the operator to perform the operation. Furthermore, a grounding hole 231 conforming to the specifications of Israel, Egypt, the United States, Switzerland and Italy is defined on the grounding terminal group 23 corresponding to the British plug specification, so that the operator can plug in the corresponding country. Rod 232 to achieve the purpose of corresponding grounding.

Please refer to the seventh to ninth A drawings, which are schematic diagrams of the first embodiment of the present invention. It can be clearly seen that the operator wants to insert a safety plug by hand or sharp object. When the first socket group 13a is seated, the first sliding element 143a cannot slide on the first rail element 141a due to the unilateral force, so the first sliding element 143a is then shaped with the first rail element 141a. Limiting to prevent the risk of electric shock; conversely, when the operator holds the plug and inserts the first socket group 13a, the plug simultaneously touches the first sliding element 143a, whereby the first elastic element 142a is compressed while the first sliding element is made The 143a maintains a balanced sliding action and generates a displacement on the first rail stage element 141a to electrically connect the plug to the set of conductive terminals. If the operator uses the second jack set 15a, the second sliding component 16a is activated in the same manner as the foregoing, and therefore will not be described again. Furthermore, the grounding A grounding portion 21a is defined on the line E pole 121a, and the grounding portion 21a is electrically connected to the grounding wire E pole 121a, thereby achieving the polarity correct when inserting a plug 3a corresponding to the German and French plug specifications. And a forced grounding portion 20a is disposed on the outer wall of the upper cover 10a, and the grounding bar 201a is disposed on the forcible grounding portion 20a and electrically connected to the grounding wire E pole 121a, thereby inserting the plug The direction can be grounded through the forced ground portion 20a, the ground rod 201a, and the ground line E pole 121a.

However, the above description is only the preferred embodiment of the present invention, and thus it is not intended to limit the scope of the present invention. Therefore, the simple modification and equivalent structural changes of the present specification and the drawings should be treated similarly. It is included in the scope of the patent of the present invention and is combined with Chen Ming.

In summary, the safety plug adapter of the present invention can achieve its efficacy and purpose when it is used. Therefore, the invention is an invention with excellent practicability, and is in accordance with the application requirements of the new patent, and is applied according to law. I hope that the trial committee will grant the invention as soon as possible to protect the inventor's hard work. If there is any doubt in the trial committee, please do not hesitate to give instructions, the inventor will try his best to cooperate, and feel really good.
