<p>Unlocking fixture for locking device for wheel bolt with key grip and threaded shaft portion with threaded blind hole; in the bolt head radial recesses from the bore; a screw tightenable in the bore and having a radial recess, which when screwed in extends through and supports an inner rotatable ring and an outer rotatable ring, from which projects radial through-grooves with the same size as the recess in the screw and which are mutually rotatable and around the screw, thus that the grooves and the recess can be turned to form a continuous channel; an axially projecting cam provided on a hub-formed center part is inserted in the channel, with an outer cam part in a recess, and an inner cam part in the space between the rings, which by relative turning are adjustable so that portions of the channel are angularly displaced and prevent the cam portions from being pulled out, whereby the unlocking fixture (120) has means (136) for cooperation with the central hole (115) in the center part (111) of the locking device, and with projections (122, 127, 128, 134) for engaging at mutual turning in blind holes (106a, 107a, 111a) in annular gable surfaces in inner and inner and outer rings and center part facing the fixture (120).</p> |
