The rotation of the fixed plate causes the fixed wheel installed at the other end to move synchronously toward the center. The isolating switch cylinder body is clamped and fixed by the three sets of fixed wheels. By providing a fixing mechanism, the three sets of fixed plates rotate synchronously under the drive of the driving motor, thereby realizing free adjustment of the position of the fixed wheel.

[0019] (3) The smokeless welding equipment used for welding the isolating switch cylinder is provided with a smoke treatment mechanism. The smoke generated by welding is conveyed to the filter box and the treatment tank by the induced draft fan. The metal debris in the smoke is filtered by the filter screen installed inside the filter box. Then the liquid extraction pump is started. The disinfection treatment liquid is introduced into the spray pipe through the liquid extraction pipe, the delivery pipe and the annular pipe, and sprayed through multiple groups of nozzles, so as to disinfect the smoke inside the treatment tank. Finally, the smoke and the sprayed disinfection treatment liquid flow into the collection box, and the smoke is discharged through the exhaust pipe on the top of the collection box, and the disinfection treatment liquid is discharged through the liquid outlet pipe on the right side of the collection box.
