1. A hanging scale sensor apparatus, comprising:
a weighing sensor;
an adapter beam;
a support base; and
a scale pan suspension structure;
wherein the adapter beam is connected to one end of a bottom face of the weighing sensor, and the support base is connected to another end of the bottom face of the weighing sensor, such that the adapter beam and the support base are positioned directly below the weighing sensor, and the scale pan suspension structure is connected to the adapter beam for positioning the hanging scale sensor apparatus;
wherein the adapter beam and the support base are connected via a limiting structure, the limiting structure comprising:
an outwardly-extending protrusion that is provided at an end portion of the adapter beam, closer to the support base, and a groove is provided at an end portion of the support base, closer to the adapter beam, and the outwardly-extending protrusion is mounted in the groove; or
a groove that is provided at an end portion of the adapter beam, closer to the support base, an outwardly-extending protrusion is provided at an end portion of the support base, closer to the adapter beam, and the outwardly-extending protrusion is mounted in the groove.
