The socket body comprises an upper cover 11, a base 12 and a middle frame 13 assembled together. The upper cover 11 has a socket and a socket protection door. The top of the base 12 has an assembly cavity. The bottom of the base 12 is protruded with a guide body 2. The adapter is inserted into the power rail through the guide body 2. The middle frame 13 is mounted in the assembly cavity, so that a bottom assembly space located below the middle frame 13 is formed at the bottom of the assembly cavity. The upper cover 11 is mounted on the middle frame 13, and a plug sleeve assembly is installed on the middle frame 13. The socket assembly includes a plurality of socket sets 14 corresponding to the electrodes, the power taking device includes a moving contact foot 31, a control circle 32 and a transmission assembly, the moving contact foot 31 is arranged at the guide body 2, the moving contact foot 31 can be unfolded and stored on the guide body 2, the control circle 32 can be rotatably configured on the socket body, the control circle 32 is limited to rotate between the base 12 and the upper cover 11, the control circle 32 drives the moving contact foot 31 to unfold or store relative to the guide body 2 through the transmission assembly, the transmission assembly includes a rocker arm 33, a conductive shaft 34 and a positioning spring 35, the rocker arm 33 includes a mounting located in the middle The mounting portion 331 and two driving arms 332 extending to both sides of the mounting portion 331 respectively. For the convenience of describing the invention, the two driving arms 332 are defined as a first driving arm a and a second driving arm b. The rocker arm 33 is positioned and rotated on the base 12 through the mounting portion 331 and is located in the bottom assembly space. One end of the positioning spring 35 is positioned and supported on the base 12, and the other end of the positioning spring 35 abuts on the first driving arm a. The first driving arm a is provided with a concave cavity and a convex point for positioning the end of the spring. The conductive shaft 34 is fixedly inserted into the mounting portion 331 of the rocker arm 33. The conductive shaft One end of the conductive shaft 34 is connected to the moving contact foot 31, and the other end of the conductive shaft 34 is an electrical connection end 341 for connecting the corresponding plug sleeve assembly 14. Usually, an elastic clip is used on the plug sleeve assembly to the electrical connection end 341 to achieve quick connection and disconnection; an avoidance channel 131 corresponding to the position of the rocker arm 33 is provided on the middle frame 13; two toggle feet 321 are provided on the control circle 32, and through the avoidance of the avoidance channel 131, the two toggle feet 321 correspond to the position of the drive arm 332 and push and cooperate, so that the control circle 32 is caused to swing through the toggle feet 321 to toggle the rocker arm 33.The avoidance of the avoidance channel 131 can be an avoidance of the toggle foot 321 or an avoidance of the driving arm 332 (such as a protrusion designed toward the middle frame position on the driving arm, and the protrusion is avoided by the avoidance of the avoidance channel and the toggle foot on the top of the middle frame to achieve corresponding cooperation). However, in order to make the structure more compact and the movement of the rocker arm more reliable, the positioning spring is effectively used to push the rocker arm to realize the automatic return function of the rocker arm (the rocker arm 33 has a critical position (also called a dead point position) under the push of the positioning spring 35.

Moreover, since the limit plug is independently processed and assembled, it can be better designed for adaptability to meet the installation and arrangement of other accessories. A card joint is provided on the circumferential cavity wall of the assembly cavity, and the middle frame is provided with a card joint surface that is snap-fitted with the card joint.
