Technical Field
[0001] The utility model relates to the technical field of electronic scales, in particular to a handheld electronic scale. Background Art
[0002] Electronic scale is a kind of weighing instrument, which is a tool to measure the mass of an object by using Hooke's law or the principle of lever balance of force. Electronic scale is mainly composed of load-bearing system, force conversion system and indication system. At present, electronic scale is widely used in daily transactions. With the improvement of people's living standards and the diversification of market transactions, handheld electronic scales have emerged, providing convenience for people's daily transactions.
[0003] The handheld electronic scales in the prior art generally consist of a wristband, a scale body, and a hook. The wristband is easily separated from the scale body, and the wristband is generally small in diameter, so it is easy to hurt your hands when weighing objects. In addition, due to the unreasonable design of the connection position between the hook and the sensor in the prior art, the sensor is easily insensitive, resulting in low weighing accuracy. In order to reduce the size, the handheld electronic scales in the prior art generally use disposable non-recyclable batteries to provide power, and the batteries need to be replaced regularly, which is inconvenient and not environmentally friendly.
