The most common scales on the market at present are kitchen scales, platform scales and baking scales, and the maximum weighing values of the kitchen scales, the platform scales and the baking scales are 1kg, 3kg, 5kg, 10kg, 20kg, 50kg and the like. In life, people can determine the maximum weighing value of the weighing tool with the required measuring range according to the maximum weighing values of different application scenes, for example, the maximum weighing value of a household kitchen scale is 3kg, and for people doing baking workshops, the maximum weighing value of the required weighing tool is more than 30 kg. In addition, the resolution (sensitivity) of the wide-range sensor is large, and the sensitivity of the weighing tool which cannot measure a small-weight object, such as a maximum weighing value of 30kg, can only be 1g, and conversely, the sensitivity of the weighing tool with high sensitivity is small, such as a weighing tool with sensitivity of 0.1g, and the maximum weighing value can only be 5kg.

However, in many cases, it is necessary to accurately weigh not only a heavy article but also a small article. In order to solve the problem, the electronic scale with double weighing functions is provided, the small weighing tool can be accommodated in the cavity of the large weighing tool, the large weighing tool can be used for weighing articles with large weight and large volume, and the small weighing tool can be used for weighing articles with small weight and small volume, so that the two weighing requirements are met, and meanwhile, the problem that different weighing tools occupy too much space can be solved by combining and placing when the electronic scale is not used.

In the prior art, when a small weighing tool is stored in a large weighing tool, the small weighing tool is usually slid into a storage cavity of the large weighing tool, and when the small weighing tool is stored, the small weighing tool easily slides out of the storage cavity, so that the small weighing tool is damaged.
