When the elastic element 5 is under force, it needs to overcome the pre-tightening force, thereby ensuring that the locked components are not easy to fall off after installation.

[0093] The transmission component 23 is provided with an elastic element fixing hole 234. The elastic element fixing hole 234 is located between the second transmission hole 233 and the center hole 235 and is close to the second transmission hole 233. One end of the elastic element 5 is inserted into the elastic element fixing hole 234 for fixation. There are multiple elastic element fixing holes 234, thereby adjusting the elastic element 5 to overcome the preload.

[0094] A transmission column 2131 is provided at the tail end of the second telescopic section 213; the transmission column 2131 at the tail end of the second telescopic section 213 of the first telescopic member 21 is rotatably connected to the first transmission hole 232 on the transmission member 23, and the tail end of the second telescopic section 213 of the second telescopic member 22 is rotatably connected to the second transmission hole 233 on the transmission member 23. The size of the transmission column 2131 matches that of the transmission hole. The transmission column 2131 includes a column body and an upper cap. The upper cap is smaller than the size of the transmission hole, which facilitates the insertion of the transmission column 2131 into the transmission hole. When the telescopic assembly 2 is in the pre-tightened state, the major diameter of the upper cap is perpendicular to the major diameter of the transmission hole, preventing the transmission column 2131 from sliding out of the transmission hole.

[0095] One end of the pusher 1 is connected to the transmission component 23, and the other end of the pusher 1 is set in the push port 43. The other end of the pusher 1 is provided with a slotted or Phillips head groove 12, which is convenient for using tools such as slotted or Phillips head screwdrivers or other tools to push the pusher 1 to move. The other end of the pusher 1 can also be provided with a special shape such as a triangular or pentagonal groove 12, which is used to push the pusher 1 to move by inserting non-standard tools into the groove 12. The intelligent power distribution terminal body 4 is provided with a push channel 42 to accommodate the pusher 1. A fixed limiting component 41 is provided in the push channel 42. A push port 43 is provided on one side wall of the intelligent power distribution terminal body 4. The push channel 42 is located at the outlet of the push channel 42 on one side wall of the intelligent power distribution terminal body 4, which is the push port 43. The pusher 1 is slidably connected to the fixed limiting component 41. There are multiple fixed limiting components 41 to ensure that the pusher 1 moves in a set direction within the fixed limiting component 41.

[0096] The pusher 1 can also be provided with an external thread 11 segment, and the push channel 42 is provided with an internal thread that matches the external thread 11 segment on the pusher 1; by rotating the tool, the pusher 1 is driven to rotate and advance within the push channel 42, thereby driving the transmission component 23 to rotate. By adopting the structure of external thread 11 and internal thread cooperation, the advancing position of the pusher 1 is changed, thereby changing the contraction state of the first telescopic component 21 and the second telescopic component 22 driven by the transmission component 23. This allows the snap-fit ​​connector 2111 to be inserted into the snap-fit ​​interface 61 for fixing or the snap-fit ​​connector 2111 to be disassembled from the snap-fit ​​interface 61, thus realizing the detachable connection function.

[0097] During installation and fixing: An elastic element 5 (torsion spring) is fixed to the transmission component 23 of the telescopic assembly 2. The elastic element 5 (torsion spring) is in a pre-tensioned state, and the telescopic assembly 2 is in a pre-tensioned state. The locking connectors 2111 at both ends of the telescopic assembly 2 have beveled surfaces 21111 to ensure smooth sliding into the locking interface 61. The vertical surfaces 21112 of the locking connectors 2111 ensure that they do not easily slide out of the locking interface 61 without force after being inserted. The connection between the beveled surface of the locking connector 2111 and the sub-locking part 12 can be a curved transition to ensure smooth sliding into the locking interface 61. The locking connector 2111 extends into and locks into the locking interface 61, achieving fixed installation.

[0098] During disassembly: Push the pusher 1, and the pusher 1 transmits the force to the transmission component 23. The elastic component 5 inside the transmission component 23 overcomes the pre-tightening force, and the telescopic component 2 is in a retracted state. The snap connector 2111 disengages from the snap interface 61 and retracts to the opening 44 on the side wall of the external intelligent power distribution terminal, thus achieving disassembly.

[0099] The overall structure is simple, easy to install and disassemble, reducing labor intensity and saving labor time.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
