[0002] Electricity meters can record the electricity usage information generated by electrical appliances inside buildings and have become popular in industrial production and residents' daily lives. Subsequent staff will send the electricity usage information data stored in the meter to the meter data reading terminal during meter reading. In this process, the infrared signal communication technology built into the meter data reading terminal can realize the data transmission function between the meter and the reading terminal, and the pairing process of electricity information and meter equipment information can be completed by obtaining meter equipment problem information through the code scanning module. At present, staff generally use handheld meter data reading terminals for reading work.

[0003] However, in the prior art, because the handheld meter data collection terminal has a large number of control buttons, it is easy for workers to accidentally touch the handheld meter data collection terminal during the entire meter reading process. In addition, since the handheld meter data collection terminal has a rectangular structure, it takes up a relatively large space when carried around, making it inconvenient to store. On the other hand, the control panel and display panel of the existing handheld meter data collection terminal are on the same plane, and the usage mode cannot be adjusted according to the user's habits, resulting in insufficient overall flexibility.
