Scale body spacing protection mechanism

The utility model relates to a scale body limiting and protecting mechanism, which belongs to an electronic measuring instrument. The scale body limiting and protecting mechanism comprises an upper scale body, a lower scale body, a weighing sensor connected between the upper scale body and the lower scale body as well as limiting pieces, the limiting pieces are wheel axles respectively arranged on the upper scale body or/and the lower scale body, the radial peripheral walls of the wheel axles are positioned on the upper end face or the lower end face of the weighing sensor, and the distance between the radial peripheral walls of the wheel axles when rotating and the upper end face or the lower end face of the weighing sensor is a variable distance. The scale body limiting and protecting mechanism has advantages of reasonable structure, convenient adjustment and facilitating daily cleaning work, and can be widely applied to electronic scales in situations with rather high sanitary requirements to the weighted
