A first plug-in terminal group 17 is pivotally disposed on the base 11 , and the first plug-in terminal set 17 is pivotally provided with an extension portion 171 having a telescopic shape;

a second plug terminal group 18 is pivotally disposed on the base 11 and interlaced with the first plug terminal group 17;

At least one auxiliary component 19 is coupled to the first plug terminal group 17;

The at least one forcible grounding portion 20 is provided with a grounding rod 201 electrically connected to the grounding wire E pole 121; at least one grounding portion 21 is electrically connected to the grounding wire E pole 121; and at least one ergonomic grip The holding portion 22 is defined at the outer wall of the upper cover 10.

In the above, the base 11 is pivotally provided with a grounding terminal group 23 corresponding to the British plug specification, and the upper cover 10 houses at least one indicator light 24 and one and the indicator light 24 and the conductive terminal group 12 The first connecting socket pushing block 26 corresponding to the American plug specification and the second jack pushing block 27 cooperating with the first jack pushing block 26 are disposed in the upper cover 10. The upper cover 10 is provided with an anti-pushing assembly 28 for urging the second plug terminal set 18, and the conductive terminal set 12 further defines a live L pole 122 and a neutral N pole 123.

With the above structure and composition design, the following is a description of the operation of the present invention. Please refer to FIG. 3 to FIG. 6E, which are schematic diagrams of the first embodiment of the present invention. It is clear that the first plug terminal set 17 and the second plug terminal set 18 of the safety plug adapter are respectively defined as European-style circular plug terminals and American flat-type plug terminals, and the present invention is exemplified. Preferably, the distance between the two types of plug-in terminal groups of the first plug-in terminal group 17 and the second plug-in terminal group 18 is different, the distance between the European-style circular plug terminals is wider, and the distance between the American flat-type plug terminals is B. Therefore, 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 are separated from each other without interference with each other; in the folded state, the first plug-in terminal group 17 The second plug terminal group 18 is folded on one side of the base 11 and does not protrude beyond the base 11, which not only reduces the space occupied by the safety plug adapter, but also does not scratch the human body or articles due to the protrusion; In the state of use, the first insertion can be selected. The terminal 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 the European plug terminal, when the operator takes When the safety plug adapter is taken, the grip portion 22 can be designed to facilitate the operator to pick up. In addition, in order to meet the safety factors and the plugs of different specifications in different countries, the sockets of many countries have a grounding end design and a grounding hole is formed in the socket, such as the United Kingdom, etc., so a grounding terminal group 23 is arranged 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. Corresponding to the grounding hole. Furthermore, the extending portion 171 pivoted by 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 is advantageous. The above-mentioned ground terminal group 23 is provided, 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 to make the European circle The plug-in terminals receive power from a British outlet. 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. It only needs to open the safety measures of the British socket, so that the plug terminal can be inserted into the socket to take power. When the operator wants to insert a jack with a large 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 terminal block 23 corresponding to the British plug specification defines a plug hole 231 conforming to the specifications of the Israeli, Egyptian, American, Swiss and Italian plugs, whereby the operator can insert the plug bar for the corresponding country required. 232, to achieve the practical purpose of the corresponding ground.

Please refer to FIG. 7 to FIG. 9A , which are schematic diagrams of a further embodiment of the present invention. It can be clearly seen that the operator wants to insert the safety plug adapter into the seat by hand or sharp objects. In the case of a jack set 13a, the first sliding element 3a cannot slide on the first rail element 141a due to the unilateral force, so the first sliding element 143a is then clamped with the first rail element 141a to prevent it from being blocked. The risk of electric shock is generated; conversely, when the operator holds the plug and inserts it into the first socket group 13a, the plug simultaneously activates the first sliding element 143a, whereby the first elastic element 142a is compressed while the first sliding element 143a is kept in balance. Acting and generating a displacement on the first rail element 141a, the plug is electrically connected to the conductive terminal set. If the operator uses the second jack set _15a , the action of the second sliding element 16a is the same as the foregoing, and therefore will not be described again. Furthermore, the grounding wire E pole 121a defines a grounding portion 21a, and the grounding portion 21a is electrically connected to the grounding wire E pole 121a, thereby achieving the insertion of a plug 3a corresponding to the German and French plug specifications. For the purpose of correct polarity, 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 forcing grounding portion 20a and is electrically connected to the grounding wire E pole 121a. Regardless of the direction in which the plug is inserted, the grounding portion 20a, the grounding bar 201a, and the grounding wire E pole 121a can be grounded.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way. Any simple modifications, equivalent changes and modifications made to the above embodiments in accordance with the technical spirit of the present invention are still Within the scope of the technical solution of the present invention.

In summary, the invention is fully in line with the needs of industrial development in terms of structural design, practicality and cost-effectiveness, and the disclosed structure is also an unprecedented innovative structure, novel, creative, practical, and relevant. The provisions of the patent requirements for inventions are therefore filed in accordance with the law.
