ABSTRACT:
A tweezer for removal of ticks has two legs (10, 12), connected at one end (11) by a loop formed spring, pinched together partly within a movable cylinder (26), which through the action of a coil spring (24) is pushed against the bent portions of the legs' (10, 12) end parts in order to exert a preset squeezing force between the end parts and their sharp edged gripping points (19). By retracting the cylinder (26) the gripping points (19) are opened and when the cylinder (26) is released, the legs' (10, 12) end portions and their gripping points (19) can grasp the tick (40) and its head (38) with such a predetermined force that the tweezer will lose its grip if the tick's head (38) has not first been loosened by turning. The turning is brought about by turning the cylinder (26), which maintains the predetermined pinching force by the help of the coil spring (24).
