This structure can prevent the problem of cable entanglement.

[0033] Then, all the parts are returned to their positions, the casting 100 can be removed, and a new casting 100 can be installed for continued processing. This is very convenient and only requires a single person to operate, which greatly reduces the thermal labor and has a good use effect.
