Abstract

The utility model discloses a three-claw flashlight fixing clamp. The three-claw flashlight fixing clamp comprises a base, a threaded rod which is vertically and fixedly arranged on the base and extends upwards, a claw fixing frame fixed at the top end of the threaded rod, evenly distributed clamping claws which are arranged on the claw fixing frame through hinge pins and torsional springs, and an inclination adjustment nut arranged on the threaded rod in a threaded mode, wherein an inwards bent clamping claw head is arranged at the top end of each clamping claw and is used for clamping a flashlight, an inwards bent leaning head is arranged at the bottom end of each clamping claw, the inclination adjustment nut is located between the claw fixing frame and the base, the outer surface of the inclination adjustment nut is a reverse conical surface, and the outer surface of the inclination adjustment nut makes contact with the leaning heads at the bottom ends of the clamping claws. The inclination adjustment nut moves up and down along the threaded rod, so that the three-claw flashlight fixing clamp drives the leaning heads at the bottom ends of the clamping claws to move outwards. Further the opening angles of the clamping claw heads at the top ends of the clamping claws are adjusted, so that the three-claw flashlight fixing clamp is suitable for clamping and fixing flashlights of different types. The three-claw flashlight fixing clamp can fix the flashlights with the diameter ranging from 5mm to 50mm.
