The limiting piece 33 abuts against the clamping member 20 from below to press the clamping member 20 in the first chamber 11. The first chamber 11 in turn keeps the first and second clamping heads 21 and 22 in the engaged state to fix the spherical body 53. The elastic member 40 is located in the second chamber 12, and the elastic member 40 pushes the guiding portion 32 away from the second chamber 12. The elastic member 40 in the embodiment is a spring, and the guiding portion 32 has a first positioning column 41, the second chamber 12 has a second positioning column 42, one end of the elastic member 40 is sleeved on the first positioning column 41, and the other end is sleeved on the second positioning column 42.

[0033] The working principle of the present application is as follows: the earring seat 60 is fixed in the mounting portion 31, and the earring 50 is fixed in the clamping member 20. The earring 50 and the earring seat 60 are aligned with the human ear. When external force acts on the rear of the piston 30 and the pushing member 10 respectively, the elastic member 40 is compressed, the guiding portion 32 slides inward along the second chamber 12, the mounting portion 31 approaches the clamping member 20, and the earring seat 60 connects the earring 50. At the same time, the guiding portion 32 drives the limiting piece 33 to disengage from the clamping member 20, and the clamping member 20 is released by the first chamber 11, and the first and second clamping heads 21 and 22 are disengaged from each other. After the external force disappears, the spring pushes the guiding portion 32 away from the second chamber 12, and the mounting portion 31 is away from the clamping member 20. The mounting portion 31 releases the earring seat 60, and the clamping member 20 releases the earring 50, and the earring device with double guiding buckles is taken out, the earring 50 and the earring seat 60 are fixed in the human ear, and the ear piercing operation is completed.

[0034] The guiding portion 32 in the embodiment has guiding buckles 34, the second chamber 12 has guiding grooves 15 extending along the sliding direction of the guiding portion 32, and the guiding buckles 34 extend out of the guiding grooves 15.
