During maintenance, the ball head needs to be removed to separate the ball head from the connecting rod to facilitate maintenance operations.

[0003] In the existing technology, when repairing urban rail transit vehicles, the distance between the ball head and the end face of the cone pin on the transportation vehicle is small, resulting in space limitations. When removing the ball head, it is impossible to knock the end face of the cone pin with a tool, which makes it difficult to remove the ball head during maintenance, and further causes the connection rod and the torque arm to be unable to be separated and removed, affecting the convenience of repairing transportation vehicles. For this reason, we propose a tool for reverse pulling and disassembly of the ball head. Utility Model Content
