Description

Technical Field

[0001] The utility model relates to the technical field of data identification, in particular to an RFID handheld terminal. Background Art

[0002] RFID handheld terminal, also known as PDA, has RFID reading and writing functions and can read RFID tags. It is a set of hardware with specific functions.

[0003] Through searching, the Chinese patent announcement number CN215182031U, application number 202122798006.6 is an RFID handheld scanning terminal, which uses a fan to drive the airflow to move the heat of the components inside the shell, and extracts the hot air inside the shell in winter. The extracted hot air passes through the air duct, and heats the hands through the air duct and the anti-slip pad. In summer, the fan is flipped over to change the direction of the airflow, and the external cool air is drawn into the shell. When the cool air passes through the air duct, it takes away the heat of the air duct, thereby cooling the hands. In this way, the fan is used to adjust the temperature of the hands while dissipating heat, thereby improving the feel of use.

[0004] With respect to the above-mentioned related technologies, the inventors found the following defects: the above-mentioned patent does not have an anti-drop function during actual use. Due to long-term use in summer and the generation of hand sweat, the RFID handheld terminal may slip from the hand, reducing the safety of the RFID handheld terminal when in use. It is also inconvenient to adjust the length of the RFID handheld terminal, which is not conducive to the user scanning the protruding labels, causing inconvenience to the user.
