Abstract: A case holder with weighing sensor that weighs accurately, has a fixing base of a weighing sensor built in the holder, and ensures the fixed end and the loading end of the weighing sensor meet weighing principle. It includes a grip and a lifting arrangement arranged at two ends of the lower surface of the grip and allowed to pass through a case surface to be fixedly connected with a stressed plate below the case surface. A neutral zone of the grip provides a fixing base for arranging a weighing sensor. A fixed end of the weighing sensor is fixedly connected on the fixing base with screw. A loading end of the weighing sensor includes a rigid and structurally closed lifting bushing fixedly connected thereon. The lifting bushing is arranged around the grip, the fixing base, and the weighing sensor and has two ends separately arranged to the corresponding lifting arrangement. The inner wall of the lifting bushing and the grip have a gap therebetween.
