  • the press plate 181 also has an internal thread 186, into which a thread 196 of a handle 195 can be screwed.
  • the handle 195 points a handle guide 197 on the front and rear Press plate connecting element 181, 182 is aligned.
  • the device 100 has an insertion aid 190.
  • the insertion aid 190 exists from a rail connected to the support element 88 via an insertion aid guide 193 connected is.
  • the insertion rod 190 slides along the insertion aid guide bar 192 and can be brought into alignment with the crossbar 172 to change the hard disk.
  • the Insertion bar 190 and cross bar 172 have the same cross section.
  • the insertion rod 190 has a nose 191 at its end which fits into the cross rod 172 fits. If the insertion rod 190 and the transverse rod 172 are in alignment, the pressing plate 180 can pushed onto the insertion rod 190 by means of the handle 195 and up to the cross rod 172 are pushed. By inserting the insertion rod 190 into the cross rod 172 grid 183 is resolved. If the insertion aid 190 is removed from the crossbar 172 removed, the grid 183 engages automatically and thereby fixes the pressing plate 180. As soon as the press plate 180 is engaged on the crossbar 172, the handle 195 can be unscrewed and the insertion aid 190 from the area above the second cutting position be moved away.
