[0026] Furthermore, a guide groove 6 capable of displacing the guide plate 11 is provided on the bus duct side plate 2, and the guide groove 6 is connected to the guide groove 5. A second fixing hole 7 connected to the first fixing hole 12 is provided on the bus duct side plate 2, and the second fixing hole 7 is connected to the guide groove 6. The first fixing hole 12 and the second fixing hole 7 are coordinated with the setting of the fixing bolts 9, thereby improving the connection strength between the bus duct cover plate 3 and the bus duct side plate 2.

[0027] Furthermore, a block 8 is provided on the bus duct side plate 2 at the top of the docking groove, and the inner wall of the block 8 is an arc surface that fits the outer surface of the docking rod 13. Through the setting of the block 8, the locking belt 19 clamped in the clamping groove 21 can be blocked, thereby preventing the locking belt 19 from being separated from the docking rod 13 due to external factors.

[0028] refer to Figure 4 The busbar duct cover plate 3 shown in the figure has guide blocks 10 symmetrically arranged on both sides of the bottom end surface of the busbar duct cover plate 3 and matched with the guide groove 5. The bottom of one side of the guide block 10 is provided with a guide plate 11 integrally formed therewith, and the guide plate 11 is provided with a first fixing hole 12 for inserting a fixing bolt 9.
