[0043] In the embodiment, after a group of prongs moves, the corresponding locking block moves and abuts against other locking blocks, and finally the other groups of prongs are locked / positioned in the socket body 100, thereby achieving interlocking between the groups of prongs 200.
[0044] In one embodiment, as shown in Figure 2 and Figure 3 The socket body 100 is internally provided with a guide groove 110, and the locking block 300 is at least partially clamped in the guide groove 110; when the group of prongs 200 is switched, the locking block 300 moves along the guide groove 110;
[0045] Specifically, the switching of the group of prongs 200 refers to the switching between the two states of extending out of the socket body 100 and being retracted into the socket body 100;
[0046] The guide groove 110 can guide the movement of the locking block 300, and ensure that after one locking block 300 moves, it can abut against other locking blocks;
[0047] Optionally, there are various structural modes of the guide groove 110;

[0049] Another structural mode is that one of the socket body and the locking block 300 is provided with a strip-shaped groove, and the other is provided with a clamping protrusion clamped in the strip-shaped groove, so that the movement can be guided.
[0050] In one embodiment, as shown in Figures 2-3 The at least one locking block is connected with an elastic mechanism 400, and the elastic mechanism 400 provides elastic force for resetting the locking block;
[0051] The elastic mechanism 400 can be a spring, a spring sheet or the like, and in the embodiment, the spring structure is preferred.
[0052] In one embodiment, the pin group 200 includes a first pin group 210, a second pin group 220 and a third pin group 230, which can be any of the following standards: Chinese standard, American standard, European standard, British standard, Australian standard and South African standard;

[0055] The shapes of the pin seats 201 of the first pin group 210, the second pin group 220 and the third pin group 230 are slightly different, but the function of the pin seat 201 is to serve as a carrier for mounting the pin 202 and facilitating installation in the socket body 100.
[0056] The shapes of the pins 202 of the first pin group 210, the second pin group 220 and the third pin group 230 are different according to the different standards, and the shapes of the pins 202 are not specifically described here, which mainly serve the function of conducting electricity.

[0060] Specifically, the first and second pin groups 210 and 220 are mounted on the socket body 100 in a substantially left-right symmetry, while the third pin group 230 is mounted on the lower shell of the socket body 100, which can be provided with a receiving groove to accommodate the third pin group 230.
[0061] Further, the lock block 300 includes a first lock block 310 corresponding to the first pin group 210, a second lock block 320 corresponding to the second pin group 220, and a third lock block 330 corresponding to the third pin group 230; the first, second, and third lock blocks 310, 320, and 330 are all mounted in the guide groove 110.
[0062] As shown in Figure 13 , the first and second lock blocks 310 and 320 are arranged in the same straight guide groove 110, and the ends of the first and second lock blocks 310 and 320 correspond or abut; the first lock block 310 is provided at the beginning with a first inclined surface 311 abutting the pin seat 201 of the first pin group 210; the second lock block 320 is also provided at the beginning with a first inclined surface 321 abutting the pin seat 201 of the second pin group 220; the third lock block 330 is arranged perpendicular to the first and second lock blocks 310 and 320, and the end of the third lock block 330 is provided as a sharp end; as shown in Figure 13 , the ends of the first and second lock blocks 310 and 320 are each provided with a second inclined surface to form a triangular gap 301 for the sharp end to be inserted, and the inclined surface formed by the sharp end of the third lock block 330 cooperates with the second inclined surface provided at the end of the first and second lock blocks 310 and 320 to push and / or abut.
[0063] As shown in Figure 13 , the first and second lock blocks 310 and 320 are substantially L-shaped, and the first inclined surface 311 of the first lock block 310 and the second inclined surface 321 of the second lock block 320 respectively abut the pin seat 201 of the first and second pin groups 310 and 320 from top to bottom.
[0064] Further, the front of the third lock block 330 is provided with a limiting protrusion 331, and the pin seat 201 of the third pin group 230 is provided with a rib 231, and the surface of the rib 231 is arc-shaped; the limiting protrusion 331 abuts the rib 231 to prevent the third pin group 230 from being triggered to extend out of the socket body 100;
[0065] As shown in Figure 3 , the elastic mechanism 400 is a spring, and the second lock block 320 is connected with a spring, and the third lock block 320 is connected with a spring.
[0066] Further, a PCB board is arranged in the socket body, and the socket body 100 is also provided with a jack 101.
[0067] As Figures 2-4 shown, when the first prong group 210 is triggered to move downward to extend out of the socket body 100, the first prong group 210 drives the first lock block 310 to move leftward; at the same time, the first lock block 310 pushes the second lock block 320 to move leftward, and the first inclined surface 321 of the second lock block 320 abuts against the prong seat 201 of the second prong group 220, so as to restrict the second prong group 220 from moving downward, thereby locking the second prong group 220;
[0068] At the same time, as Figure 3 and Figure 4 shown, the first lock block 310 pushes the third lock block 330 to move downward, so that the limiting protrusion 331 of the third lock block 330 abuts against the rib 231 of the third prong group 230, thereby locking the third prong group 230;
[0069] As Figures 8-9 shown, when the second prong group 220 is triggered to move downward to extend out of the socket body 100, the second prong group 220 drives the second lock block 320 to move rightward; at the same time, the second lock block 320 pushes the first lock block 310 to move rightward, and the first inclined surface 311 of the first lock block 310 abuts against the prong seat 201 of the first prong group 210, so as to restrict the first prong group 210 from moving downward, thereby locking the first prong group 210;
[0070] At the same time, as Figure 9 and Figure 4 shown, the second lock block 320 pushes the third lock block 330 to move downward, so that the limiting protrusion 331 of the third lock block 330 abuts against the rib 231 of the third prong group 230, thereby locking the third prong group 230;
[0071] As Figures 10-12 shown, when the third prong group 230 is triggered to rotate to extend out of the socket body 100, the rib 231 of the third prong group 230 is disengaged from the limiting protrusion 331 and pushes the third lock block 330 to move, as Figure 12 shown, the rib 231 abuts against the limiting protrusion 331 upward and downward; as Figure 11 shown, the third lock block 330 moves upward, and the third lock block 330 pushes the first lock block 310 to move rightward, so that the first inclined surface 311 of the first lock block 310 abuts against the prong seat 201 of the first prong group 210, so as to restrict the first prong group 210 from moving downward, thereby locking the first prong group 210; the third lock block 331 pushes the second lock block 320 to move leftward, so that the first inclined surface 321 of the second lock block 320 abuts against the prong seat 201 of the second prong group 220, so as to restrict the second prong group 220 from moving downward, thereby locking the second prong group 220.
[0072] When the third pin group 230 is rotated and reset into the socket body 100, the position of the rib 231 changes during the rotation of the third pin group 230, and the limiting block 331 no longer abuts upward and downward, as shown in Figure 12 The third locking block 330 will be reset and moved downward under the elastic force of the spring, as shown in Figure 4 The position of the rib 231 abuts leftward and rightward with the limiting block 331 again.
[0073] Through the above, the interlocking function between the multiple pin groups 200 can be realized.
[0074] The above description of disclosed embodiments enables those skilled in the art to carry out or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application.
