In addition, in order to allow users to listen to the sound signals provided by the electronic products without disturbing others, earphones have become a necessary accessory for each electronic product. In addition, earphones also provide better sound transmission for listeners, allowing them to clearly hear and understand the sound content.

[0003] During the earphone assembly process, the operator needs to fix and maintain the pressure of the earphone shell to allow the glue to solidify. Patent application number CN202323615117.4 discloses a Bluetooth earphone charging needle pressure maintaining tool, which includes a base, a mounting plate, a first quick clamp and a second quick clamp. The mounting plate is vertically installed on the top of the base and is close to one end of the base. The first quick clamp is installed on the other end of the base in a way that it can move in the horizontal direction. The output end of the first quick clamp is opposite to the mounting plate. The base is provided with a positioning block between the first quick clamp and the mounting plate. The side of the positioning block is provided with a positioning cavity for placing the Bluetooth earphone. The earphone is placed in the cavity, and the first quick clamp and the second quick clamp are manually pushed to maintain the pressure of the earphone. This type of device needs to manually push the clamp, which is inefficient, and it needs to wait for one earphone to complete the pressure maintaining operation before the next earphone can be pressure maintained, which is inefficient.
