Measuring mechanism and scale

The embodiment of the utility model discloses a measuring mechanism and a scale, and relates to the technical field of weighing equipment. The measuring mechanism comprises a body provided with a containing space, a transparent fluid box partially filled with fluid is installed in the containing space, and the fluid has shading performance, that is, light beams irradiated to the fluid can be partially or completely absorbed and/or reflected by the fluid. Further, the measuring mechanism further comprises a processing unit, a light-emitting assembly and a sensing assembly, when the body is horizontal in the horizontal direction, the sensing assembly can sense a light beam emitted by the light-emitting assembly, and when the body inclines by a preset angle in the horizontal direction, one of the light-emitting assembly or the sensing assembly is below the surface of the fluid, so that the light beam is shielded, and the body is prevented from being damaged. The sensing assembly cannot sense. The processing unit
