  • Publication number: 20250241797
    Abstract: The present invention relates to the technical field of visual ear picks. By the arrangement of the driving portion and the straight tube portion, the driving portion is assembled on the visual ear pick. One end of the straight tube portion is connected to the driving portion; and the straight tube portion movably sleeves the visual ear pick, so that the driving portion can drive the straight tube portion to move on the visual ear pick in the axial direction of the straight tube portion. When the tweezer head is assembled on the visual ear pick, the other end of the straight tube portion is opposite to the tweezer head. Therefore, the driving portion drives the straight tube portion to move on the visual ear pick in the axial direction of the straight tube portion, which can conveniently enable the tweezer head to achieve the function of a tweezer.
