Embodiment Construction
[0029] Figure 1 to Figure 5Shown is an inspection device 10 according to the invention, which is suitable for being connected to a threaded screw. The inspection device 10 has a base body 11 , a torsion body 12 received in the base body 11 and an adjustment disc 13 fixed at a lower end 14 of the base body 11 . The one-piece torsion body 12 is accommodated in the base body 11 coaxially to the longitudinal center axis 15 of the testing device 10 , wherein the hexagonally formed upper end 16 of the torsion body 12 protrudes upwards from the base body 11 and is positioned with For coupling or mating to screw leadscrews. Below the upper end 16 , the torsion body 12 has a shoulder 17 with a widened diameter, which has two abutment surfaces 17 ′ and 17 ″ spaced apart from one another in the circumferential direction, which are in contact with the base body. 11 has two stop surfaces 18' and 18" corresponding to it on its upper shoulder 18. The shoulder 17 of the torsion body 12 me...
