The U.S. plug 30 includes a U.S. plug bracket 34 and a pair of U.S. pins 35 disposed on the U.S. plug bracket 34 . The American-style plug bracket 34 is provided with a guide hole 32 for inserting into the guide post 61, and the American-style plug bracket 34 is located in the gap 26 of the British-style plug bracket 24, and the American-style pin 35 is located between the ground pin and the electrode pin of the British-style pin 25, Make its layout more compact and reasonable. The periphery of the U.S. plug holder 34 is arc-shaped, and a second guide block 31 extending outward is provided on the arc-shaped contour. The American pin can be rotated to form a "eight" shape, which facilitates the use of different sockets and expands the scope of use. the

The Euro plug 40 includes a Euro plug bracket 44 and Euro pins 45 provided on the Euro plug bracket 44 . The Euro-style plug bracket 44 is provided with a guide hole 42 inserted into the guide column 61, and the Euro-style plug bracket 44 is positioned outside the grounding pin of the British pin 25. Such a layout reduces waste of space and makes the whole structure more compact. The periphery of the Euro-style plug bracket 44 is arc-shaped, and a third guide block 41 extending outward is provided on the arc-shaped contour. the

The British plug bracket 24, the American plug bracket 34 and the European plug bracket 44 form a circle together and are placed in the housing 10. The first guide block 21, the second guide block 31, and the third guide block 41 are evenly distributed on the same Circumferentially, when rotating the turntable 50, it can enter and exit the guide groove 53 in turn, driving the British plug bracket 24, the American plug bracket 34 and the European plug bracket 44 to extend out of the housing 10 in turn. the

When assembling, first put the British plug 20, the American plug 30 and the European plug 40 into the turntable 50 in turn, so that the first guide block 21 and the second guide block 31 rest on the first step 54, and the third guide block 41 rests on the second step 55 . Then the guide holes 22, 32, 42 of the British plug 20, the American plug 30 and the European plug 40 are aligned with the guide post 61 of the socket 60, and the rotating disk 50 and the three plugs are connected to the socket 60 as a whole; A baffle 64 is installed on the guide column 61 to limit the British plug 20 and the American plug 30 . Then, the casing 10 is installed on the periphery of the three plugs, and the turntable 50 can be rotated relative to the socket 60 and the casing 10 to complete the assembly. the

During use, turn the rotating disk 50, because the guide groove 53 communicates with the first step and the second step, when the rotating disk 50 rotates to the position of one of the plugs (the European plug 40 is used as an example below), the European plug 40 The third guide block 41 falls into the guide groove 53 from the second stage step 55; since the guide groove 53 is in a "V" shape, when the turntable 50 continues to rotate, driven by the descending section of the guide groove 53, the third guide block The guide block 41 moves downward, that is, the European pin 45 of the European plug 40 is driven out of the housing 10, as shown in FIG. It is convenient to insert the European-style plug 40 into the corresponding jack; then continue to rotate the turntable 50, driven by the rising section of the guide groove 53, the third guide block 41 is moved upwards, that is, the European-style pin 45 of the European-style plug 40 is driven to retract to Inside the casing 10 until the third guide block 41 rests on the second step 55 again. Continue to rotate the turntable 50 to drive the prongs of the British plug 20 and the American plug 30 to extend out of the housing 10 or retract the housing 10. The process is similar to the above, so it will not be described in detail. the

In this embodiment, the second step 55 is on the upper side of the first step 54, and the depth of the second step 55 is greater than the depth of the first step 54, that is, the ratio of the axial distance between the second step 55 and the turntable 50 is The first step 54 is far away from the axis of the rotating disk 50; at the same time, the length of the third guide block 41 of the European plug 40 is greater than the length of the first guide block 21 and the second guide block 31 of the British plug 20 and the American plug 30, And respectively cooperate with the second step 55 and the first step 54, like this, when the third guide block 41 arrives at the position of the first step 54, because the length of the third guide block 41 is longer, it is impossible to enter the first step. step 54, and continue to go up under the drive of guide groove 53, until the position of second step 55, it will enter and rest on the second step 55; and the British plug 20 and the American plug 30 When the first guide block 21 and the second guide block 31 reach the first step 54 , they will enter and rest on the first step 54 . It can be understood that only one step can be provided, and the guide blocks of the three plugs can be set to have the same length, which can also be realized. the

The utility model drives the guide block of the plug through the guide groove 53, so that the plug extends out of the housing 10 and retracts the housing 10 in turn, avoiding the vulnerable structures such as springs in the prior art, and has a simple, reliable and easy-to-use structure. advantage. the
