From FIG. 10 it can be seen that the locking piece is pretensioned via a spring 27 about the axial piece 19 of a projection 16 of one of the members 7-9 in such a way that the locking piece 21 is pressed into the locked position. To release this locking piece from the locked position, as has been previously described, the force of this spring 27 must be overcome. The stop surfaces 24 can likewise be seen from this FIG. 10, which stop surfaces define the stretched position of the members 7-10. In addition, the stop elements 25 are also visible, represented by the facing surfaces 26 of the projections, which define the completely diverted position of the base body 4.
A further embodiment example of the device according to the invention is shown in FIGS. 17 to 19. The base body 4 shown here is once again made up of a plurality of members, of which only the two members 7, 8 are partially visible, which are connected together in a way pivotable about a pivot axis 12 via an articulation 11. The members 7, 8 each comprise a tubular element 40, in each of whose ends 41 a pivoting part 42 or respectively 43 is inserted and fixed, forming the articulation 11. The two pivoting parts 42 and 43 are connected together in a way pivotable about the pivot axis 12. The one pivoting part 42 has a protruding tongue 44, which forms the stop element 25. The other pivoting part 43 is provided with a stop face 45. When actuating the pulling element 14, the two pivoting parts 42 and 43 are diverted, as is shown in FIG. 18, until the stop element 25 comes to abut the stop face 45. The two pivoting parts 42, 43 and with them the members 7 and 8 are thereby situated in the completely diverted position. With this design of the articulation 11, the stress on the stop elements 25 and the stop faces 45 is less.
