The first plug 21, the second plug 22 and the third plug 23 are respectively limited in position in the accommodating cavity 13 by a guide rod 41, a guide rod 42 and a guide rod 43. By arranging the second rotating shaft 32 and connecting the third plug 23 with the second rotating shaft 32, and arranging the three plugs in a staggered manner, the internal structure of the converter is simplified, and the blocking condition among different plugs is avoided.

In one embodiment, referring to fig. 8, 10 and 11, the converter further includes a fourth plug 24, the first plug 21 and the second plug 22 are connected to the first rotating shaft 31, and the third plug 23 and the fourth plug 24 are connected to the second rotating shaft 32. In order to realize the staggered arrangement of the four plugs, a certain height difference H is provided between the inclined surface 326 and the inclined surface 327 of the second rotating shaft. In this structure, the first rotating shaft 31 corresponds to the first plug 21 and the second plug 22, and the second rotating shaft 32 corresponds to the third plug 23 and the fourth plug 24, so that the converter of the present embodiment includes four kinds of plugs which can be individually extended, and can be applied to common power outlets on the market at present.

In one embodiment, referring to fig. 12, the first plug 21, the second plug 22, the third plug 23 and the fourth plug 24 are four plugs with different types, respectively. The first plug 21 has two contacts, and a certain included angle is formed between the two contacts; the second plug 22 has two contacts arranged parallel to each other; the third plug 23 has three contacts, which are positioned in an isosceles triangle, wherein the bottom surfaces of the contacts of the first plug 21, the second plug 22 and the third plug 23 are all rectangular. The fourth plug 24 has two contacts and is cylindrical. In order to meet different requirements of users, the shape of the plug can be set to other types according to requirements.

In one embodiment, referring to fig. 13 and 14, the axis of the second rotating shaft 32 is parallel to the axis of the first rotating shaft 31, and the second rotating shaft 32 and the first rotating shaft 31 can rotate around their own axes. And the first end 311 of the first rotating shaft 31 is provided with a first groove 318, and the first end 321 of the second rotating shaft 32 is provided with a second groove 328 corresponding to the first groove 318. A locking lever 6 is disposed between the first rotating shaft 31 and the second rotating shaft 32, two ends of the locking lever 6 correspond to the first groove 318 and the second groove 328, two end portions of the locking lever 6 are in a sharp-angled shape, and the locking lever 6 can slide between the first rotating shaft 31 and the second rotating shaft 32. The first groove 318 and the second groove 328 are both fan-shaped, and the center thereof forms a sharp included angle, so that the first groove and the second groove can be tightly matched with the end parts of the two ends of the locking rod 6, and a good locking effect is achieved on the rotating shaft. The first recess 318 and the second recess 328 have similar structures, and the second recess 328 is taken as an example for illustration, and the first recess 318 can be referred to. The two side surfaces 3281 and 3282 near the end surface of the first end 321 of the second rotating shaft 32 are smooth arc surfaces, so that the locking rod 6 can smoothly slide out and enter the other rotating shaft. When one of the rotating shafts rotates, the locking lever 6 is pushed by the rotating shaft to move toward the groove of the other rotating shaft, thereby locking the other rotating shaft and fixing it. At any one time, only one end of the locking bar 6 is located within the first recess 318 or the second recess 328. Accordingly, when the converter is provided with three or more rotation shafts, locking can be performed by increasing the number of the locking levers. So that only one rotary shaft can be rotated at a time, i.e. only one plug can be extended from the inside of the housing 11 to the outside of the housing.

The present embodiment establishes the mutual connection and mutual control relationship between the first rotating shaft 31 and the second rotating shaft 32 by using the locking lever 6, so that when the plug-and-socket converter contains more than two plugs, the effect of pushing out only one plug at a time can be realized by only reasonably setting the number of the rotating shafts.

In an embodiment, referring to fig. 5, fig. 15 and fig. 16, the first plug 21 of the converter further includes a limiting portion 214, and the limiting portion 214 is connected to the main body portion 211. Meanwhile, the converter further comprises a limiting assembly, and the limiting assembly is accommodated in the accommodating cavity 13. The limiting assembly comprises a bottom plate 510 and a vertical column 520, the bottom plate 510 is arranged at the bottom of the accommodating cavity 13, and the vertical column 520 is fixedly arranged on the bottom plate 510. The pillar 520 is provided with a protrusion 5201, and the protrusion 5201 is used for cooperating with the limiting portion 214 to limit the position of the first plug 21.

Referring to fig. 15, an end of the protrusion 5201 of the pillar 520 away from the bottom plate 510 is provided with a third inclined surface 5201X, and the third inclined surface 5201X faces the key portion 210 side. The stopper 214 is provided with a fourth slope 214X having an inclination equal to that of the third slope 5201X, and the third slope 5201X is attached to the fourth slope 214X. When the first plug 21 moves along the sliding groove 313 to reset or is carried at ordinary times without use, the fourth inclined surface 214X on the limiting portion 214 and the third inclined surface 5201X on the upright column 520 are abutted against each other, so that the limiting effect on the first plug 21 is realized, and the first plug 21 is limited to move towards the direction extending out of the outer side of the housing 11.

The lower end face of the protrusion 5201 is a plane 5201Y approximately perpendicular to the axis of the first rotating shaft 31, and when the first plug 21 completely slides out, the upper end face of the limiting portion 214 is clamped with the lower end face 5201Y of the protrusion 5201, so that the limiting effect of the first plug 21 after sliding out is realized, and the purpose of fixing the plug after sliding out is achieved.
