Vacuum-lifting device for assembling and testing optical connector

摘要

A vacuum-lifting device includes a holding block and a nozzle. The holding block defines a holding hole and a threaded hole communicating with the holding hole. The nozzle includes a first section that is slidably received in the holding hole and a second section. The second section extends from the first section and has an outer diameter smaller than an outer diameter of the first section.

主权项

1. A vacuum-lifting device, comprising:
a holding block defining a holding hole and a threaded hole communicating with the holding hole; and a nozzle comprising a first section and a second section, the first section slidably received in the holding hole, the second section collinearly extending from the first section and having an outer diameter smaller than an outer diameter of the first section, the holding block further comprising a screw screwing into the threaded hole to abut the nozzle and thus fixing the nozzle in the holding hole; wherein the holding block is substantially rectangular and comprises a top surface, a bottom surface opposite to the top surface, and a side surface perpendicularly connecting the top surface and the bottom surface, the holding hole extends through the top surface and the bottom surface along a direction that is slanted about 45 degrees relative to the top surface.
