[0027] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and accompanying drawings.

[0028] The most critical concept of the present invention is that the first plug assembly is rotatably connected to the rotating shaft, so that the two first plug assemblies can rotate relative to each other after being opened, so that the two first plug assemblies are arranged in an eight-shaped shape or a straight line, thereby enabling the multi-adaptive plug assembly to adapt to sockets of various specifications.

[0029] Please refer to Figures 1 to 18 The multi-adaptive plug assembly 2 includes a rotating shaft 4 and two first plug assemblies 5. The two first plug assemblies 5 are rotatably arranged on the rotating shaft 4, and the central axis of the rotating shaft 4 and the rotation central axis of the first plug assembly 5 are arranged perpendicular to each other.

[0030] From the above description, it can be seen that the beneficial effects of the present invention are: the multi-adaptive plug assembly 2 of the present invention can use the rotating shaft 4 to open and close the first plug assembly 5, which is convenient for users to carry and store. The first plug assembly 5 after opening can be adapted to the Chinese standard two-hole socket and the American standard two-hole socket, and the user can rotate the opened first plug assembly 5 so that the two first plug assemblies 5 are arranged in an eight-shaped shape, so that the multi-adaptive plug assembly 2 can be adapted to the inverted eight-shaped socket, such as the Australian standard socket and the Chinese standard three-hole Chinese standard socket; in addition, when the user rotates the two first plug assemblies 5 into a straight line arrangement, the multi-adaptive plug assembly 2 can also be adapted to the European standard three-hole socket. Therefore, the multi-adaptive plug assembly 2 of the present invention can be adapted to a variety of different types of sockets, has strong versatility, and greatly reduces the usage limitations of the plug assembly; the electrical appliance with the multi-adaptive plug assembly 2 can be adapted to a variety of types of sockets, which greatly facilitates the user's use; the multi-adaptive plug assembly 2 is small in size and is particularly suitable for miniaturized electrical appliances.

[0031] Furthermore, the rotating shaft 4 includes two coaxially arranged rotating sub-shafts 41 , one of the first plug components 5 can be rotatably disposed on one of the rotating sub-shafts 41 , and the other of the first plug components 5 can be rotatably disposed on the other rotating sub-shaft 41 .

[0032] From the above description, it can be seen that the rotating sub-shaft 41 and the first plug assembly 5 can form a separate component, which is convenient for manufacturers to process and produce, and is beneficial to improving the production efficiency of the multi-adaptive plug assembly 2 and reducing manufacturing costs; in addition, the production and installation accuracy of the separate components are easier to control, which is beneficial to improving the yield rate of the multi-adaptive plug assembly 2.

[0033] Furthermore, the first plug assembly 5 includes a first metal sheet 52, and the first plug assembly 5 is rotatably connected to the rotor shaft 41 through a pin shaft 53. The pin shaft 53 is respectively connected to the first metal sheet 52 and the rotor shaft 41, and there is a gap 9 at one end of the two rotor shafts 41 that are close to each other.

[0034] As can be seen from the above description, the first metal sheet 52 is electrically connected to the electrical adapter or electrical component of the appliance via the rotating sub-shaft 41, facilitating internal wiring of the appliance, ensuring more stable internal electrical conduction, and thus improving the service life of the appliance. The presence of the gap 9 prevents the two first metal sheets 52 from short-circuiting.

[0035] Furthermore, it also includes an insulating connector, which connects the two rotating sub-shafts 41 respectively.

[0036] As can be seen from the above description, the insulating connector can isolate the two rotating sub-shafts 41 and at the same time enable the two rotating sub-shafts 41 to be linked, which is convenient for user operation.

[0037] Furthermore, the first plug assembly 5 includes a seat body 51 , and linkage tooth segments 54 are provided on the peripheral wall of the seat body 51 . The linkage tooth segments 54 on the two seat bodies 51 are meshed with each other.

[0038] As can be seen from the above description, the two first plug assemblies 5 are linked by the linkage tooth segment 54, which is convenient for user operation. It is easy to understand that the base 51 is made of insulating material to prevent the two first plug assemblies 5 from short circuiting.

[0039] Furthermore, a platform 16 is provided on the rotating shaft 4, and the first plug assembly 5 includes a seat body 51, and the seat body 51 is rotatably connected to the platform 16 through a pin shaft 53. A first adjusting tooth surface 17 is provided on the side of the seat body 51 close to the platform 16, and a second adjusting tooth surface matching the first adjusting tooth surface 17 is provided on the platform 16. The pin shaft 53 is provided with an elastic member 18 for driving the platform 16 and the seat body 51 to approach each other.

[0040] As can be seen from the above description, the first plug assembly 5 can rotate 360°, allowing the two first plug assemblies 5 to be arranged in a figure-eight pattern or in a straight line. The first and second adjustment tooth surfaces, in conjunction with the elastic member 18, can lock the rotation angle of the first plug assembly 5, thereby facilitating user operation. Preferably, the first and second adjustment tooth surfaces each include multiple tooth blocks arranged in a circle around the pin 53, each having a trapezoidal cross-section. The elastic member 18 can be made of a spring, a spring clip, or other elastic material.

[0041] Furthermore, it also includes a mounting member 10 rotatably arranged on the rotating shaft 4, the mounting member 10 is provided with a receiving groove 11, the mounting member 10 is provided with two plug-in components 12, the receiving groove 11 has two conductive members 13 arranged at intervals, the conductive member 13 is connected to the plug-in component 12, and the conductive member 13 cooperates with the first plug component 5.

[0042] As can be seen from the above description, after the mounting member 10 with two pin assemblies 12 is connected to the first plug assembly 5, the plug assembly can be adapted to a European standard two-hole socket, further improving the versatility of the plug assembly.

[0043] Furthermore, a mounting block 7 is provided in the receiving groove 11 , and an insulating insert 6 is rotatably provided on the mounting block 7 . The mounting block 7 is located between the two conductive members 13 .

[0044] From the above description, it can be seen that the presence of the insulating insert 6 enables the multi-adapter plug assembly 2 to better adapt to the European standard three-hole socket, improves the stability of the connection between the multi-adapter plug assembly 2 and the European standard three-hole socket, and helps to enhance the user experience.

[0045] Furthermore, the first plug assembly 5 includes a seat body 51, and a linkage tooth segment 54 is provided on the peripheral wall of the seat body 51, and the linkage tooth segments 54 on the two seat bodies 51 are engaged with each other; it also includes two second plug assemblies 15 rotatably arranged on the rotating shaft 4, and the two first plug assemblies 5 are located between the two second plug assemblies 15.

[0046] As can be seen from the above description, the first and second plug assemblies are arranged reasonably and do not interfere with each other. The second plug assembly 15 is a British standard plug. In this way, the two second plug assemblies 15 and the insulating plug 6 on the mounting block 7 can form a standard British standard three-pin plug, making the multi-adaptive plug assembly 2 more compliant with user usage habits and enhancing the user experience. It is easy to understand that the second plug assembly 15 can be connected to the rotating shaft 4 or not. For the purpose of safe use of electricity, it is preferred that the second plug assembly 15 is not connected to the rotating shaft 4 (to prevent the first plug assembly 5 from being energized when the second plug assembly 15 is connected).

[0047] The electrical appliance comprises a base 1 and the above-mentioned multi-adapter plug assembly 2. The base 1 is provided with a receiving groove 3. The multi-adapter plug assembly 2 is rotatably arranged in the receiving groove 3 via the rotating shaft 4.

[0048] As can be seen from the above description, the appliances can be used with sockets of various specifications in multiple countries, reducing the difficulty of using electricity and bringing great convenience to users. The appliances include but are not limited to adapter sockets, chargers, speakers, mosquito repellent liquid heaters, plug-in wall lamps, hair dryers, terminal devices, etc.

[0049] Example 1

[0050] Please refer to Figure 1-8 , Embodiment 1 of the present invention is: an electrical appliance, including but not limited to an adapter socket, a charger, a speaker, a mosquito-repellent liquid heater, a plug-in wall lamp, a hair dryer, a terminal device, etc., the electrical appliance specifically includes a base 1 and a multi-adaptive plug assembly 2, the base 1 is provided with a receiving groove 3, the multi-adaptive plug assembly 2 includes a rotating shaft 4 and two first plug assemblies 5, the two first plug assemblies 5 are rotatably arranged on the rotating shaft 4, the center axis of the rotating shaft 4 and the rotation center axis of the first plug assembly 5 are arranged perpendicular to each other, the multi-adaptive plug assembly 2 is rotatably arranged in the receiving groove 3 through the rotating shaft 4, and a transfer conductor (such as a conductive clip of a transfer socket, etc.) or an electrical component (such as a heating wire, a speaker unit, etc.) is provided in the base 1.

[0051] The first plug assembly 5 includes a connected base 51 and a first metal sheet 52. The first plug assembly 5 is rotatably connected to the rotating shaft 4 via a pin 53, wherein the central axis of the pin 53 is perpendicular to the central axis of the rotating shaft 4. To prevent short circuits between the two first plug assemblies 5, the pin 53 is optionally configured to be disconnected from the rotating shaft 4 and / or the first metal sheet 52, that is, the rotating shaft 4 and the first metal sheet 52 are disconnected. In this case, the first metal sheet 52 is directly in contact with the switching conductor or the power-consuming component, wherein the switching conductor or the power-consuming component and the first metal sheet 52 are connected via a conductive spring structure.

[0052] The rotating shaft 4 is provided with a platform 16, and the seat 51 is rotatably connected to the platform 16 via the pin 53. A first adjustment tooth surface 17 is provided on the side of the seat 51 close to the platform 16, and a second adjustment tooth surface that cooperates with the first adjustment tooth surface 17 is provided on the platform 16. The pin 53 is provided with an elastic member 18 for driving the platform 16 and the seat 51 closer to each other. In this way, in the first plug assembly 5, the first metal sheet 52 connected to the seat 51 can achieve 360° rotation without dead angles. In other words, the insertion ends of the two first metal sheets 52 in the two first plug assemblies 5 can be arranged in an eight-shaped pattern or in a straight line, thereby enabling the multi-adaptive plug assembly 2 to adapt to sockets of more specifications. Preferably, the insertion ends of the two first metal sheets 52 are arranged close to each other.

[0053] Optionally, the multi-adapter plug assembly 2 further includes an insulating insert 6, which is located in the receiving groove 11. One end of the insulating insert 6 is rotatably connected to the base 1 via a rotating shaft, wherein the rotating shaft is arranged parallel to the rotating shaft 4. In this way, the multi-adapter plug assembly 2 can be better adapted to the figure-eight three-hole socket, thereby improving the stability of the connection between the multi-adapter plug assembly 2 and the figure-eight three-hole socket, and helping to enhance the user experience. Preferably, the multi-adapter plug assembly 2 further includes a mounting block 7, which is provided on the base 1 and located in the receiving groove 3. The mounting block 7 is provided with a receiving groove for accommodating the insulating insert 6, and the insulating insert 6 is connected to the mounting block 7 via the rotating shaft.

[0054] Example 2

[0055] Please refer to Figure 1-8The second embodiment of the present invention further improves the connection between the first plug assembly 5 and the rotating shaft 4 based on the first embodiment. The difference from the first embodiment is that the rotating shaft 4 includes two coaxially arranged rotating sub-shafts 41 corresponding one-to-one with the two first plug assemblies 5. Specifically, the rotating shaft 4 includes two coaxially arranged rotating sub-shafts 41, one of the first plug assembly 5 is rotatably mounted on one rotating sub-shaft 41, and the other first plug assembly 5 is rotatably mounted on the other rotating sub-shaft 41. As will be readily understood, the platform 16 is mounted on the rotating sub-shafts 41.

[0056] In this way, a rotating sub-shaft 41 and a first plug assembly 5 form a module structure, which is convenient for manufacturers to process and control the assembly accuracy of components, and is conducive to improving the yield rate of the multi-adaptive plug assembly 2.

[0057] Furthermore, a coupling device 8 is included, and the coupling device 8 is connected to the two rotating sub-shafts 41 respectively, so that the two rotating sub-shafts 41 can be linked to each other, which is convenient for user operation.

[0058] Example 3

[0059] Please refer to Figure 1-8 The third embodiment of the present invention is a further improvement on the conduction form between the first plug assembly 5 and the adapter conductor or the electrical component based on the second embodiment. The difference from the second embodiment is that the first metal sheet 52 is conducted with the rotating shaft 4.

[0060] Please focus on Figure 8 Specifically, the pin shaft 53 is respectively connected to the first metal sheet 52 and the rotor shaft 41, and a gap 9 is formed at one end of the two rotor shafts 41 close to each other. In order to prevent the two first plug assemblies 5 from being connected to each other and causing a short circuit, the coupling device 8 is made of an insulating material, that is, the coupling device 8 is an insulating connector.

[0061] Such a conductive form between the first plug assembly 5 and the adapter conductor or the electrical component can facilitate the internal wiring of the electrical appliance, so that the first plug assembly 5 can withstand multiple openings and closings, thereby extending the service life of the multi-adapter plug assembly 2.

[0062] Example 4

[0063] Please refer to Figure 1-12Embodiment 4 of the present invention is a further improvement on the multi-adaptive plug assembly 2 based on any one of Embodiments 1 to 3. The difference from any one of Embodiments 1 to 3 is that the multi-adaptive plug assembly 2 also includes a mounting member 10 rotatably arranged on the rotating shaft 4, and the mounting member 10 is provided with a receiving groove 11, and the mounting member 10 is provided with two plug-in components 12, and the receiving groove 11 has two conductive members 13 spaced apart, and the conductive member 13 is conductively connected to the plug-in component 12, and the conductive member 13 cooperates with the first plug assembly 5.

[0064] Optionally, the conductive member 13 is a U-shaped conductive metal clip. The first metal sheet 52 is folded through the opening of the accommodating groove 11 and then clamped by the U-shaped conductive metal clip, thereby achieving electrical connection between the plug assembly 12 and the adapter conductor or electrical component. In this way, the multi-adaptive plug assembly 2 of this embodiment can be adapted to British standard two-round hole sockets, further enhancing the adaptability of the multi-adaptive plug assembly 2. Preferably, the inner side of the U-shaped conductive metal clip is provided with contact bumps to ensure more stable electrical connection between the U-shaped conductive metal clip and the first metal sheet 52. It is easy to understand that although the plug assembly 12 in this embodiment includes a cylindrical insertion end to adapt to British standard sockets, in other embodiments, the cylindrical insertion end can be replaced with a sheet-shaped or other shaped insertion end to adapt to other types of sockets. Specifically, when the insertion end of the plug assembly 12 is sheet-shaped, the multi-adaptive plug assembly 2 can be suitable for relatively narrow installation environments.

[0065] Optionally, when the first plug assembly 5 and the mounting member 10 are simultaneously received in the receiving slot 3, the two are located on either side of the rotating shaft 4. This makes operation more convenient for the user because when rotating the first plug assembly 5 about the rotating shaft 4, there is no need to first unscrew the mounting member 10 and then separate the first metal sheet 52 and the conductive member 13.

[0066] Of course, when the first plug assembly 5 and the mounting member 10 are simultaneously received in the receiving groove 3, it is also feasible that the two are located on both sides of the rotating shaft 4, that is, the first metal sheet 52 and the conductive member 13 always maintain contact and conduction. In this way, the lateral length of the multi-adapter plug assembly 2 can be reduced, so that the multi-adapter plug assembly 2 can be miniaturized when received, making it easier for users to carry and store.

[0067] Optionally, the plug-in column assembly 12 can be telescopically arranged relative to the mounting member 10, that is, when the mounting member 10 is in a retracted state, part or all of the plug-in column assembly 12 can be received in the mounting member 10. Specifically, the plug-in column assembly 12 is slidably connected to the conductive member 13, and the sliding direction of the plug-in column assembly 12 is consistent with its length direction.

[0068] Example 5

[0069] Please refer to Figure 1-12 The fifth embodiment of the present invention is a further improvement on the setting position of the mounting block 7 and the insulating plug 6 based on the fourth embodiment. The difference from the fourth embodiment is that the mounting block 7 is not set in the receiving groove 3 of the base 1, but is set in the receiving groove 11 of the mounting member 10.

[0070] Specifically, the mounting block 7 with the insulating insert 6 is disposed in the receiving groove 11 and between the two conductive members 13. In this way, the mounting member 10 can have only one side open, which is convenient for the user to hold and helps enhance the user experience.

[0071] Preferably, the two conductive members 13 are fixed to the two sides of the mounting block 7. In this way, the mounting block 7 can provide a mounting position for both the insulating insert 6 and the conductive member 13, and can also isolate the two conductive members 13, so that the mounting block 7 can achieve multiple uses. Optionally, the mounting block 7 and the mounting member 10 are connected and fixed by a slot and a pin 14.

[0072] Example 6

[0074] The first plug assembly 5 includes a connected base 51 and a first metal sheet 52. The first plug assembly 5 is rotatably connected to the rotating shaft 4 via a pin 53, wherein the central axis of the pin 53 is perpendicular to the central axis of the rotating shaft 4. To prevent short circuits between the two first plug assemblies 5, the pin 53 is optionally configured to be disconnected from the rotating shaft 4 and / or the first metal sheet 52, that is, the rotating shaft 4 and the first metal sheet 52 are disconnected. In this case, the first metal sheet 52 is directly in contact with the switching conductor or the power-consuming component, wherein the switching conductor or the power-consuming component and the first metal sheet 52 are connected via a conductive spring structure.

[0075] Furthermore, the base body 51 is provided with a linkage tooth segment 54 on its peripheral wall. The linkage tooth segments 54 on the two base bodies 51 mesh with each other. This allows the two first plug assemblies 5 to be linked and rotated into a figure-eight arrangement, thereby enabling the multi-adapter plug assembly 2 to adapt to a socket having a figure-eight jack. Preferably, the insertion end of the first metal sheet 52 is eccentrically positioned relative to the pin 53. Specifically, the insertion end of the first metal sheet 52 is located on the side of the pin 53 away from the linkage tooth segment 54.

[0076] Optionally, the multi-adapter plug assembly 2 further includes an insulating insert 6, which is located in the receiving groove 11. One end of the insulating insert 6 is rotatably connected to the base 1 via a rotating shaft, wherein the rotating shaft is arranged parallel to the rotating shaft 4. In this way, the multi-adapter plug assembly 2 can be better adapted to the figure-eight three-hole socket, thereby improving the stability of the connection between the multi-adapter plug assembly 2 and the figure-eight three-hole socket, and helping to enhance the user experience. Preferably, the multi-adapter plug assembly 2 further includes a mounting block 7, which is provided on the base 1 and located in the receiving groove 3. The mounting block 7 is provided with a receiving groove for accommodating the insulating insert 6, and the insulating insert 6 is connected to the mounting block 7 via the rotating shaft.

[0077] Example 7

[0078] Please refer to Figure 1-2 and Figure 13 The seventh embodiment of the present invention is a further improvement on the connection between the first plug assembly 5 and the rotating shaft 4 based on the sixth embodiment. The difference from the sixth embodiment is that the rotating shaft 4 includes two rotating sub-shafts 41 arranged coaxially and corresponding to the two first plug assemblies 5. Specifically, the rotating shaft 4 includes two coaxially arranged rotating sub-shafts 41, one of the first plug assembly 5 is rotatably mounted on one of the rotating sub-shafts 41, and the other of the first plug assembly 5 is rotatably mounted on the other rotating sub-shaft 41 (refer to the embodiment of the present invention). Figure 8 ).

[0079] In this way, a rotating sub-shaft 41 and a first plug assembly 5 form a module structure, which is convenient for manufacturers to process and control the assembly accuracy of components, and is conducive to improving the yield rate of the multi-adaptive plug assembly 2.

[0080] Furthermore, a coupling device 8 is included, and the coupling device 8 is connected to the two rotating sub-shafts 41 respectively, so that the two rotating sub-shafts 41 can be linked to each other, which is convenient for user operation.

[0081] Example 8

[0082] Please refer to Figure 1-2 and Figure 13The eighth embodiment of the present invention is a further improvement on the conduction form between the first plug assembly 5 and the adapter conductor or the electrical component based on the seventh embodiment. The difference from the seventh embodiment is that the first metal sheet 52 is conducted with the rotating shaft 4.

[0083] Specifically, the pin 53 is connected to the first metal sheet 52 and the rotor shaft 41 respectively, and there is a gap 9 at one end of the two rotor shafts 41 close to each other (which can be combined with reference to Figure 8 ), in order to prevent the two first plug assemblies 5 from being connected to each other and causing a short circuit, the coupling component 8 is made of an insulating material, that is, the coupling component 8 is an insulating connector.

[0084] Such a conductive form between the first plug assembly 5 and the adapter conductor or the electrical component can facilitate the internal wiring of the electrical appliance, so that the first plug assembly 5 can withstand multiple openings and closings, thereby extending the service life of the multi-adapter plug assembly 2.

[0085] Embodiment 9

[0086] Please refer to Figure 1-2 and Figure 13-18 Embodiment 9 of the present invention is a further improvement on the multi-adaptive plug assembly 2 based on any one of Embodiments 6 to 8. The difference from any one of Embodiments 6 to 8 is that the multi-adaptive plug assembly 2 also includes a mounting member 10 rotatably arranged on the rotating shaft 4, and the mounting member 10 is provided with a receiving groove 11, and the mounting member 10 is provided with two plug-in components 12, and the receiving groove 11 has two conductive members 13 spaced apart, and the conductive member 13 is conductively connected to the plug-in component 12, and the conductive member 13 cooperates with the first plug assembly 5.

[0087] Optionally, the conductive member 13 is a U-shaped conductive metal clip, and the first metal sheet 52 is folded into the U-shaped conductive metal clip through the opening of the accommodating groove 11 and then clamped by the U-shaped conductive metal clip, thereby achieving electrical connection between the plug assembly 12 and the adapter conductor or electrical component. In this way, the multi-adaptive plug assembly 2 of this embodiment can be adapted to European standard two-round hole sockets, further enhancing the adaptability of the multi-adaptive plug assembly 2. Preferably, the inner side of the U-shaped conductive metal clip is provided with contact bumps to make the electrical connection between the U-shaped conductive metal clip and the first metal sheet 52 more stable.

[0088] Optionally, when the first plug assembly 5 and the mounting member 10 are simultaneously received in the receiving slot 3, the two are located on either side of the rotating shaft 4. This makes operation more convenient for the user because when rotating the first plug assembly 5 about the rotating shaft 4, there is no need to first unscrew the mounting member 10 and then separate the first metal sheet 52 and the conductive member 13.

[0089] Of course, when the first plug assembly 5 and the mounting member 10 are simultaneously received in the receiving groove 3, it is also feasible that the two are located on both sides of the rotating shaft 4, that is, the first metal sheet 52 and the conductive member 13 always maintain contact and conduction. In this way, the lateral length of the multi-adapter plug assembly 2 can be reduced, so that the multi-adapter plug assembly 2 can be miniaturized when received, making it easier for users to carry and store.

[0090] Optionally, the plug-in column assembly 12 can be telescopically arranged relative to the mounting member 10, that is, when the mounting member 10 is in a retracted state, part or all of the plug-in column assembly 12 can be received in the mounting member 10. Specifically, the plug-in column assembly 12 is slidably connected to the conductive member 13, and the sliding direction of the plug-in column assembly 12 is consistent with its length direction.

[0091] Example 10

[0092] Please refer to Figure 1-2 and Figure 13-18 The tenth embodiment of the present invention is a further improvement on the setting position of the mounting block 7 and the insulating plug 6 based on the ninth embodiment. The difference from the ninth embodiment is that the mounting block 7 is not set in the receiving groove 3 of the base 1, but is set in the receiving groove 11 of the mounting member 10.

[0093] Specifically, the mounting block 7 with the insulating insert 6 is disposed in the receiving groove 11 and between the two conductive members 13. In this way, the mounting member 10 can have only one side open, which is convenient for the user to hold and helps enhance the user experience.

[0094] Preferably, the two conductive members 13 are fixed to the two sides of the mounting block 7. In this way, the mounting block 7 can provide a mounting position for both the insulating insert 6 and the conductive member 13, and can also isolate the two conductive members 13, so that the mounting block 7 can achieve multiple uses. Optionally, the mounting block 7 and the mounting member 10 are connected and fixed by a slot and a pin 14.

[0095] Example 11

[0096] Please refer to Figure 1-2 and Figure 13-18 The eleventh embodiment of the present invention is a further improvement of the multi-adapter plug assembly 2 based on any one of the sixth to tenth embodiments, and is different from any one of the sixth to tenth embodiments in that:

[0097] The multi-adaptive plug assembly 2 further includes two second plug assemblies 15 rotatably disposed on the rotating shaft 4 , and the two first plug assemblies 5 are located between the two second plug assemblies 15 .

[0098] Specifically, the second plug assembly 15 includes a second metal sheet 151, the width direction of the second metal sheet 151 is perpendicular to the width direction of the insulating plug 6, and the thickness of the second metal sheet 151 is greater than the thickness of the first metal sheet 52. Simply put, the two second plug assemblies 15 cooperate with the insulating plug 6 to enable the multi-adapter plug assembly 2 to better adapt to the European standard three-hole socket.

[0099] When the multi-adaptive plug assembly 2 of this embodiment is stored, the first and second plug assemblies are located on the same side of the rotating shaft 4 .

[0100] In summary, the multi-adaptive plug assembly and electrical appliance provided by the present invention can be well adapted to sockets of multiple countries and specifications, are highly versatile, and have few limitations on use; and are small in size and suitable for miniaturized electrical appliances.

[0101] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent transformations made using the contents of the present invention's description and drawings, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.
