1. A tweezer part for a visual ear pick, applied to a visual ear pick and configured to drive a tweezer head assembled on the visual ear pick, wherein the tweezer part comprises:
a driving portion, configured to be assembled on the visual ear pick; and
a straight tube portion, wherein one end of the straight tube portion is connected to the driving portion, and the straight tube portion is configured to be movably arranged on the visual ear pick and to resist against the tweezer head;
wherein the driving portion comprises:
a U-shaped connecting seat, wherein the connecting seat is configured to be assembled on the visual ear pick; and
a U-shaped pressing portion having two upper ends and a bottom, wherein the connecting seat is located in the pressing portion and connected to the pressing portion at the two upper ends of the pressing portion, and a gap is maintained between the pressing portion and the connecting seat; the one end of the straight tube portion, away from the tweezer head, is connected to the bottom of the pressing portion;
wherein the tweezer part is configured in a manner that when the pressing portion is pressed, the bottom of the pressing portion deforms, and thus drives the straight tube portion to move towards the tweezer head in the axial direction of the straight tube portion, and the straight tube portion pushes the tweezer head, so that the tweezer head is in a clamping state; and
when the pressing portion is released, the pressing portion returns to an original shape, and thus drives the straight tube portion to move away from the tweezer head in the axial direction of the straight tube portion, and the straight tube portion is separated from the tweezer head, so that the tweezer head is in a releasing state;
wherein the U-shaped pressing portion comprises:
two first elastic plates, wherein the two first elastic plates are arranged on two opposite sides of the connecting seat, and the two first elastic plates are respectively connected to two opposite side walls of the connecting seat; the gap is reserved between the two first elastic plates and the two opposite side walls of the connecting seat; and
a second elastic plate, wherein two opposite ends of the second elastic plate are respectively connected to the two first elastic plates, thereby forming the U-shaped pressing portion; the one end of the straight tube portion, away from the tweezer head, is connected to the second elastic plate;
the tweezer part is configured in a manner that when the two first elastic plates are pressed towards each other, the two first elastic plates deform and drive the second elastic plate to deform away from the connecting seat; the second elastic plate drives the straight tube portion to move towards the tweezer head in the axial direction of the straight tube portion; and
when the two first elastic plates are released, the two first elastic plates return to original shapes and drive the second elastic plate to return to an original shape; and the second elastic plate drives the straight tube portion to move away from the tweezer head in the axial direction of the straight tube portion.
