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. ## Claims ### Claim 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. ### Claim 2 (depends on 1) The vacuum-lifting device of claim 1, wherein the threaded hole is defined in the side surface. ### Claim 3 (depends on 1) The vacuum-lifting device of claim 1, wherein an end of the second section opposite to the first section tapers at a 45-degree angle relative to a longitudinal direction of the second section to form a holding surface for holding objects. ### Claim 4 (depends on 3) The vacuum-lifting device of claim 3, wherein the nozzle comprises a buffer ring attached to the holding surface. ### Claim 5 (depends on 4) The vacuum-lifting device of claim 4, wherein the buffer ring is made of rubber. ### Claim 6 (depends on 1) The vacuum-lifting device of claim 1, further comprising a base and a sliding block, the sliding block being slidably fixed on the base, the holding block being fixed to the sliding block. ### Claim 7 A vacuum-lifting device, comprising: a holding block defining a holding hole and a threaded hole communicating with the holding hole; 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; a base; and a sliding block, the sliding block being slidably fixed on the base, the holding block being fixed to the sliding block; wherein the base is substantially rectangular and comprises an upper surface and a rail, the rail extends along a lengthwise direction of the base and has a trapezoidal cross-section, the sliding block is also rectangular and comprises a first surface, to which the holding block fixed, and a second surface opposite to the first surface, the sliding block defines an engaging groove in the second surface, the sliding block is fixed on the base by engagement between the engaging groove and the rail.
