Multiple conductive strips 24 are installed on the rear side of the track front cover 2, with three conductive strips 24 respectively connecting to the neutral wire, live wire, and ground wire in the power supply line. The three conductive strips 24 are respectively connected to terminals 21. Multiple equally spaced socket housings 32 are integrally formed on the track front cover 2 to fix the socket housings 32 to the track front cover 2. The socket housings 32 and the track front cover 2 are integrally injection molded, which not only simplifies the structure but also reduces material usage. The reduced dosage lowers production costs and significantly enhances the connection strength between the two components. A rotating ring 5 is rotatably mounted on the inner wall of the socket housing 32. The outer side of the rotating ring 5 has anti-slip textures to increase friction and prevent slippage during rotation. An insulating base 36 is installed inside the socket housing 32.

The conductive sleeve 73 is in close contact with the conductive shaft 71 to ensure good conductivity between the conductive shaft 71 and the conductive sleeve 73. The conductive sleeve 73 is connected to the adjacent conductive pin 27. A transmission component 74 that cooperates with the toggle block 75 is fixedly connected to the outside of the conductive shaft 71. When the rotating ring 5 rotates, it will drive the toggle block 75 to rotate. The toggle block 75 causes the conductive shaft 71 to rotate through the transmission component 74. The conductive shaft 71 drives the first contact arm 72 to rotate around the conductive shaft 71 as the center. The first contact arm 72 contacts or separates from the conductive contact component 25, thereby realizing the power-on / off of the circuit.

[0039] The second power-on / off mechanism 8 includes two swaying plates 81 movably mounted on the socket housing 32 and two extension plates 83 fixed inside the socket housing 32.

A rotating groove 86 is opened on one side of the extension plate 83, and one side of the swing plate 81 abuts against the rotating groove 86. When the rotating ring 5 rotates, it will drive the spring 84 to move. The spring 84 will be gradually compressed. When the spring 84 exceeds the dead point, the spring 84 will spring out and push the swing plate 81 to swing. The swing plate 81 drives the second contact arm 82 to move, so that the second contact arm 82 contacts or separates from the conductive contact 25, thereby realizing the circuit opening and closing.

[0040] The third power-off mechanism 9 includes a rotating cylinder 96 rotatably mounted on the socket housing 32 and fixed blocks 91 symmetrically arranged inside the rotating ring 5.

When the third contact arm 95 rotates, the arc-shaped portion 97 always remains in contact with the conductive block 94, thereby ensuring that the conductive pin 27 is always connected to the third contact arm 95. A conductive block 94 is provided on one side of the conductive pin 27. The side abuts against the arc-shaped part 97. A round rod 92 is provided on one side of the fixing block 91. A connecting arm 93 is fixedly connected to the outside of the rotating cylinder 96. One end of the connecting arm 93 is rotatably connected to the round rod 92. When the rotating ring 5 rotates, it will drive the fixing block 91 to rotate. The fixing block 91 drives the round rod 92 to move. The round rod 92 causes the rotating cylinder 96 to rotate through the connecting arm 93. The rotating cylinder 96 drives the third contact arm 95 to rotate, so that the third contact arm 95 contacts or separates from the conductive contact 25, thereby realizing the circuit power on and off.

[0043] The rotating ring 5 has a slot 34 on one side, and the inner wall of the socket housing 32 has a limiting block 33 that cooperates with the slot 34. The limiting block 33 cooperates with the slot 34 to limit the rotation angle of the rotating ring 5 and prevent it from rotating excessively.

[0044] The socket housing 32 has a socket panel 6 installed on one side. The socket panel 6 has a socket hole for inserting a plug. The socket panel 6 can limit the rotation ring 5 and prevent the rotation ring 5 from separating from the front cover of the track 2. One side of the socket panel 6 abuts against the rotation ring 5. The socket housing 32 is threaded with a screw 35. The screw 35 is used to fix the socket panel 6, thereby realizing the connection and fixation between the socket panel 6 and the socket housing 32. The screw 35 is threadedly connected to the socket panel 6.

[0045] Two overload protectors 23 are installed between the front cover 2 of the track and the bottom box 1 of the track. The overload protectors 23 are used to provide overload protection.
