Technical Examples
- The present invention relates to a device to rotate a previously unrotatable receiver used with helmets, preferably aircraft helmets.
- A saw including a handle, a saw blade, a front protective bow and a rear protective bow pivotally connected with the front protective bow. When unfolding the saw blade, the saw blade presses the front protective bow and makes the front protective bow drive the rear protective bow to pivot away from the handle. At this time, the front protective bow, the rear protective bow and the handle define an enclosed space. When folding the saw blade, the saw blade presses the front protective bow to pivot toward the handle, whereby the front protective bow and the rear protective bow are at least partially accommodated in a receiving slot of the handle.
- The invention relates to a protective device for an injection needle or infusion needle, comprising a needle holder at the proximal end of the needle, on whose shaft a protective element for the needle tip can be moved, said protective element being prevented, by an engagement device between the needle and the protective element, from being moved past the needle tip, and a grip part being provided between the protective element and the needle holder for the purpose of moving or securing the protective element.
