[0015] Optionally, support rods are fixedly connected to both sides of a side of the nut away from the anti-wear ring, and one end of the support rod away from the nut is fixedly connected to the same rotating plate.

[0016] By adopting the above technical solution, the operator can manually rotate the nut by rotating the plate.

[0017] Optionally, the length of the support rod is greater than the length of the threaded rod.

[0018] By adopting the above technical solution, it is prevented that the rotating plate abuts against the limiting plate when the nut has not yet abutted against the second connecting plate, causing the nut to be unable to move downward.

[0019] Optionally, the length of the connecting block is smaller than the total thickness of the first connecting plate and the second connecting plate.

[0020] By adopting the above technical solution, when the connecting block is rotated into the second groove, the connecting block is prevented from extending out of the second groove, resulting in the nut being unable to abut against the second connecting plate.

[0021] Optionally, the connecting member includes a fixing bolt arranged on one side of the limiting plate, and an output end of the fixing bolt passes through the limiting plate and is threadedly connected to one end of the threaded rod.

[0022] By adopting the above technical solution, when the nut is severely worn and cannot be used, the limit plate can be disassembled by removing the fixing bolt, and the nut can be screwed out from the threaded rod for replacement.

[0023] In summary, the beneficial effects of this application are as follows:

[0024] 1. The present application is provided by the coordination between the connection block, the threaded rod and the nut. When in use, the two cables are connected through the connector and placed in the lower cover. The cables are extended through the wire holes. The upper cover is then placed on the lower cover.
