Rotary joint 16 is preferably a universal joint.

[0035] When one side of the hammering plane contacts the anode guide rod 60, the hammer head 13 can freely adjust the angle of the hammering plane due to the presence of the swivel joint 16, ensuring that the hammering plane is parallel to the surface of the anode guide rod 60. This guarantees that the hammering plane and the surface of the anode guide rod 60 are in close contact, thereby increasing the contact area between the hammer head 13 and the anode guide rod 60. The structure of the universal joint 16 is existing technology and will not be described in detail here.

[0036] exist Figure 2 and Figure 3 In this embodiment, the busbar lifting frame is further equipped with a control module (not shown in the figure) and a voltage drop detector (not shown in the figure).
