DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an earlobe perforator for so-called piercing.

(Prior Art) Instruments for piercing the earlobe for use in pierced earrings are well known, such as Japanese Patent Publication No. 59-30401. The device of the present invention is a type of plunger-structured device that uses a cartridge sealed to maintain sterility until use, and includes a plunger assembly consisting of a support member and an actuating portion that are combined so as to be able to slide relative to each other. A cartridge is set at the tip, and the piercing needle is inserted into the earlobe by pressing the actuator.

(Technical Problem) Therefore, in the instrument of the invention described above, the force of the finger operating the instrument is the force that directly pierces the earlobe with the piercing needle. Therefore, depending on the operator's movements, the piercing time may be longer or shorter (depending on the level of skill). However, it is difficult to overcome the resistance of the earlobe and insert the piercing needle in the desired direction. This is a difficult task to perform with a fingertip press operation.

The present invention solves the above-mentioned problems, and its purpose is to:

(Function) The earlobe perforator 50 configured as described above functions as follows in use. Initially, the device is in the state shown in FIG. 3, with the puller 2 in the advanced position by the first spring 3 and the injection shaft 4 in the retracted position with the second spring 5 fully compressed. Then, the sealed cartridge C was taken out, the front and rear members 11 and 12 were separated, and the bottle 43 and the locking piece 40 were engaged with the notch 38 of the sliding member 10 and the locking groove 37 of the main body, respectively. Set (Figure 4). In this state, both the front and rear members 11, 12 are sufficiently separated.

Next, as shown in FIG. 5, the perforator 50 is brought close to the earlobe Y, the earlobe is positioned between the front and rear members 11 and 12, and the puller 2 is pulled (and the front member 11 slides toward the rear member 12). Then, the earlobe Y is sandwiched between the two members 11 and 12, and thereby the perforator can be fixed with respect to the earlobe in the correct desired direction.The strength of this fixation is adjusted by the tension of the puller 2. Of course, it is assumed that the cartridge C is hygienically clean and the earlobe Y is also disinfected.

In the case of a hole puncher equipped with a safety device 60, the cartridge C
When the next earlobe Y is positioned between the front and rear members 11 and 12 of the cartridge C, the safety element 63 is moved back to the operating position 62, and the operating lever 8 is ready to be operated. . If the left and right safety elements 63L and 63R move separately, move them both to the operating position 62 (
9 to 12).

In this state, when either the operating lever 8L or 8R is pushed down, the locking member 7 is disengaged from the locking part 6 of the injection shaft 4, and the injection shaft 4 moves forward at once due to the elasticity of the second spring 5 that has accumulated pressure. Since the piercing needle 41 is ejected, the piercing needle 41 instantly penetrates the earlobe Y and the needle tip fits into the stopper 42 (FIG. 6). When the piercing needle 41 is injected, the tip 23 of the injection shaft 4
enters the receiving hole 46, the piercing needle 41 breaks the stop member 48 with its head and is ejected.

(Effects) The present invention is constructed and operates as described above, so by gripping the puller 5 while pulling it, the earlobe Y can be held with both the front and rear members 11 and 12 of the cartridge. When the operation lever 8 is operated while the piercing direction is fixed, the piercing needle can be inserted into the earlobe in an instant due to the elasticity of the second spring 5 that has accumulated pressure. Therefore, even if you are not an expert, the ideal drilling will be stable and effective.
