Fixator for fixing bronchoscope adjusting knob

Abstract

The utility model discloses a fixator for fixing a bronchoscope adjusting knob. The fixator comprises a fixing base plate, a first buckle and a bottom plate, the number of the first buckles is at least two, the first buckles are arranged on the fixing base plate, and the first buckles and the fixing base plate form a first containing groove suitable for containing the adjusting knob. The bottom plate is arranged on the side, away from the containing groove, of the fixed base plate, and a plurality of ejector pins are arranged on the side, facing the fixed base plate, of the bottom plate. The fixed base plate is provided with avoiding holes used for avoiding the ejector pins, and the ejector pins penetrate through the avoiding holes and can independently move relative to the avoiding holes in the direction perpendicular to the fixed base plate so as to be matched with the outer contour of the adjusting knob. Through the arrangement of the first buckle, the adjusting knob can be clamped in the first containing groove. When the adjusting knob is clamped in the first containing groove, due to the fact that the ejector pin can move relative to the receding hole in the direction perpendicular to the fixing base plate, the ejector pin penetrating out of the fixing base plate can be attached to the outer contour of the adjusting knob, a good limiting effect is achieved, and stable fixing of the adjusting knob is achieved.
