When the first sliding frame 210 slides relative to the housing 100, the first pins 220 extend out of the housing 100 through the first opening 110 or retract into the housing 100.

[0040] The second pin assembly includes a second sliding frame 310 and at least two second pins 320. The second sliding frame 310 can be slidably installed in the housing 100, and the at least two second pins 320 are protruded from the second sliding frame 310. When the second sliding frame 310 slides relative to the housing 100, the second pins 320 extend out of the housing 100 or retract into the housing 100 through the second opening 120. The second sliding frame 310 is disposed between the first rod 211 and the second rod 212, that is, the second sliding frame 310 is located in the recessed area of ​​the first sliding frame 210.

[0041] In this embodiment, in the arrangement of the first sliding frame 210 and the second sliding frame 310, the second sliding frame 310 is located in the recessed area of ​​the first sliding frame 210, which improves the density between the first sliding frame 210 and the second sliding frame 310, so that the internal structure of the converter of this embodiment is more compact. In this way, the converter of this embodiment can use a smaller housing 100, reduce its overall volume, and facilitate miniaturization.

[0042] Further, continue to refer to Figures 1 to 3 As shown, in order to facilitate pushing the first pin assembly and the second pin assembly, the housing 100 further has a second side portion adjacent to the first side portion, and the second side portion is provided with a first slide groove 130 and a second slide groove 140 spaced and arranged in parallel.

[0043] The first pin assembly further includes a first sliding button 230. The first sliding button 230 can be slidably disposed in the first sliding groove 130, and one end of the first sliding button 230 is disposed in the housing 100 and connected to the first sliding frame 210. The other end of the first sliding button 230 is exposed outside the housing 100. The user can push and pull the first sliding frame 210 through the first sliding button 230 to achieve the extension and retraction of the first pin 220.

[0044] The second pin assembly further includes a second sliding button 330. The second sliding button 330 can be slidably inserted into the second sliding groove 140, and one end of the second sliding button 330 is inserted into the housing 100 and connected to the second sliding frame 310. The other end of the second sliding button 330 is exposed outside the housing 100. The user can push and pull the first sliding frame 210 through the second sliding button 330 to achieve the extension and retraction of the second pin 320.

[0045] Exemplarily, the first pin 220 of this embodiment includes a first live pin, a first neutral pin and a ground pin, and the first live pin, the first neutral pin and the ground pin are used as British standard pins. Among them, the first rod body 211 is provided with a ground pin, and the second rod body 212 is provided with a first live pin and a first neutral pin. Correspondingly, the number of the first openings 110 is three, and the three first openings 110 are respectively used for the first live pin, the first neutral pin and the ground pin to extend out of the housing 100 or retract into the housing 100. Of course, according to actual needs, the ground pin can be set on the second rod body 212, and the first live pin and the first neutral pin can be set on the first rod body 211.

[0046] Exemplarily, the second pins 320 include a second live pin and a second neutral pin. There are two second openings 120 , which are used to allow the second live pin and the second neutral pin to extend out of the housing 100 or retract into the housing 100 .

[0047] Continue to refer to Figure 4a and Figure 4b As shown, the second live wire pin and the second neutral wire pin can be rotated to a first position parallel to each other and can be rotated to a second position in an eight-shaped shape. The second live wire pin and the second neutral wire pin in the first position are used as national standard pins, American standard pins and Japanese standard pins; the second live wire pin and the second neutral wire pin in the second position are used as Australian standard pins.

[0048] Specifically, a first connection hole and a second connection hole are arranged in a spaced relationship on the second sliding frame 310.

The second live wire pin is rotatably connected to the first connection hole through the first connection shaft, and the second neutral wire pin is rotatably connected to the second connection hole through the second connection shaft.

[0049] Continue to refer to Figure 4a and Figure 4b As shown, a first stopper 340 is provided at the edge of the first connection hole, and a second stopper 350 is provided at the edge of the second connection hole. The first stopper 340 is used to abut against the second live wire pin when the second live wire pin is rotated clockwise or counterclockwise at a first preset angle in the first posture;

[0050] The second limiting block 350 is used to abut against the second neutral line pin when the second neutral line pin is rotated by a second preset angle in a clockwise direction or a counterclockwise direction in the first posture.

[0051] When the second live pin is rotated by a first preset angle in a clockwise direction in the first posture, and the second neutral pin is rotated by a second preset angle in a counterclockwise direction, the second live pin and the second neutral pin are in a second posture.

[0052] Alternatively, when the second live wire pin is rotated counterclockwise by a first preset angle in the first posture, and the second neutral wire pin is rotated clockwise by a second preset angle, the second live wire pin and the second neutral wire pin are in the second posture.

[0053] Further, the first limit block 340 has a first limit surface and a second limit surface. When the second live wire pin is rotated clockwise at a first preset angle in the first posture, it abuts against the first limit surface; when the second live wire pin is rotated counterclockwise at a first preset angle in the first posture, it abuts against the second limit surface. The second limit block 350 has a third limit surface and a fourth limit surface. When the second neutral wire pin is rotated clockwise at a second preset angle in the first posture, it abuts against the third limit surface; when the second neutral wire pin is rotated counterclockwise at a second preset angle in the first posture, it abuts against the fourth limit surface.

[0054] In summary, the first limiting block 340 and the second limiting block 350 can enable the second live wire pin and the second neutral wire pin to stably maintain the second posture, so as to be used as Australian standard pins.

[0055] Furthermore, if Figure 2 and Figure 3 As shown, in order to improve the plug-in diversity of the converter and adapt to use in more countries, the converter of this embodiment also includes a third pin assembly.

[0056] The first side portion is further provided with a third opening 150, and the third pin assembly includes a third sliding frame 410 and at least two third pins 420.

[0058] In order to enable the plug sleeve 430 and the third plug pin 420 to extend outward from the housing 100, a slide rail 431 formed along the sliding direction of the third sliding frame 410 is provided on the plug sleeve 430, and a slider 450 matching the slide rail 431 is protruded on the third sliding frame 410. Figure 6 As shown, when the third pin 420 extends outward, the slider 450 abuts against the side wall of the slide rail 431, thereby driving the plug sleeve 430 to extend outward together. A limiting portion 432 is also provided on the outer side of the plug sleeve 430. When the plug sleeve 430 and the third pin 420 extend outward from the housing 100 together, the limiting portion 432 abuts against the inner side of the side wall of the housing 100 where the third opening 150 is opened, so as to prevent the plug sleeve 430 from being separated from the housing 100.

[0059] In addition, in order to facilitate pushing the third pin assembly, the second side portion of the housing 100 is further provided with a third slide groove 160 spaced and arranged in parallel with the first slide groove 130 and the second slide groove 140. The third pin assembly further includes a third slide button 440, which can be slidably inserted into the third slide groove 160.
