Specifically, the transmission rod 2 is rotated, and the cable or copper busbar is squeezed and fixed between the end of the transmission rod 2 and the insulating fixing part 6 to realize the fixation of the copper busbar or cable. The whole operation process is simple and convenient, does not require professional tools, and the operation process saves time and effort, which solves the problem in the prior art that the operation process is complicated and requires the use of professional tools to complete.

[0027] Preferably, the quick connection device provided in the present application has a cable connected to it when the terminal block 4 is installed. The connection device provided in this embodiment is mainly used to realize the quick connection of the copper bus or cable between the end of the right transmission rod 2 and the insulating fixing member 6.

[0028] Furthermore, the insulating fixing part 6 is U-shaped, and the insulating fixing part 6 includes a connecting part 7, a first fixing part 8 and a second fixing part 9. The first fixing part 8 and the second fixing part 9 are parallel and respectively connected to both sides of the connecting part 7. The first fixing part 8 is connected to the end of the insulating connecting tube 1 away from the terminal 4. Specifically, the connecting part 7, the first fixing part 8, and the second fixing part 9 are connected to form a U shape, and the copper busbar or cable is clamped by the inner wall of the second fixing part 9 and the end of the transmission rod 2. Preferably, a U-shaped auxiliary plate 25 is connected to both ends of the connecting part 7, and both sides of the auxiliary plate 25 are connected to the first fixing part 8 and the second fixing part 9, so that a clamping space is formed between the connecting part 7, the first fixing part 8, the second fixing part 9, and the auxiliary plate 25. Preferably, a reinforcing block is connected to the inner side of the connecting part 7, the first fixing part 8, the second fixing part 9, and the auxiliary plate 25.

[0029] Furthermore, a metal connection groove 10 is provided inside the second fixing portion 9.

Preferably, the polygon can be a triangle, rectangle, hexagon or octagon.

In detail, the limiting column 19 has a third internal thread 20. The third internal thread 20 and the fourth external thread 22 are first threadedly matched with each other at a specified length, and then the limiting column 19 is controlled to pass the conductive rod 3 through the limiting cylinder 18 and the insulating connecting cylinder 1 and then connected to the insulating fixing part 6. At the same time, the limiting column 19 is installed in the limiting cylinder 18, and then the terminal 4 is controlled so that the third external thread 21 and the third internal thread 20 thereon are matched and connected according to the specified length.

[0034] Furthermore, a protective tube 23 coaxial with and of the same diameter as the insulating connecting tube 1 is connected to the end of the insulating connecting tube 1 near the terminal 4. A metal ring 24 is connected to the protective tube 23, which is connected to the terminal 4. The protective tube 23 protects and conceals the end of the transmission rod 2, the end of the conductive rod 3, and the limiting tube 18.
