The earphone to be pressed is placed in the fixed seat, the corresponding cylinder is started, the piston rod of the cylinder is extended, the pressing block is lowered, and the earphone is pressed after the pressing block contacts the earphone. After the earphone is pressed and pressure maintained for a period of time, the pressing of the earphone is completed, the cylinder is started, the piston rod of the cylinder is shortened, the pressing block is raised, the pressing rod is pressed, and the pressing rod moves on the base. Since the pressing rod is threadedly connected to the rotating shaft, when the pressing rod moves, the rotating shaft rotates, and the gear rotates with the rotating shaft. Since the gear is meshed with the rack, when the gear rotates, the rack moves, the push rod rises, and the top of the push rod passes through the through hole and contacts the earphone of the fixed seat, which pushes the earphone up. After the earphone reaches the top of the fixed seat, the earphone is removed. After releasing the push rod, the spring pushes the push rod back to the initial position. When the push rod moves, the rotating shaft rotates in the opposite direction, and the push rod drops back to the initial position. After the earphone is pressed, the earphone can be ejected from the fixed seat by pressing the push rod, which is very convenient to remove the earphone.

[0008] Preferably, the fixing bases are fixed in the mounting grooves by bolts. The corresponding fixing bases are installed according to the model of the earphones, which can meet the pressing requirements of earphones of different models.

[0009] Compared with the existing technology, the utility model has the following advantages:

[0010] After the earphones are pressed together, the earphones can be pushed out of the fixing seat by pressing the pressure rod, making it very convenient to remove the earphones.
