On, make to draw high unthreaded hole of the shaft in the plane of stop sleeve top above screw rod after installing with cylinder sleeve tray combination, will drive
Nut draws high the support face contact being screwed into above screw rod up to stop sleeve from after combination installation, using spanner to driving spiral shell
Mother applies torque and is fastened, by realizing cylinder sleeve to be torn open from cylinder using the reaction force with supporting plane on stop sleeve
It is taken out in body, but above-mentioned dismantling device, cylinder sleeve dismounting is carried out in such a way that spanner tightens nut, on the one hand long-term work meeting
Keep operator tired out, so that the efficiency of work is influenced, on the other hand since the volume of stop sleeve is larger, so that entire dismounting
Tool is inconvenient to carry.
