CONSTITUTION:When a capsule 10, a push rod 15 and a timing rod 19 are moved simultaneously in the right direction by an operator's push operation, the tip of a piercing pin 2 abuts on about the surface of an earlobe. In this state, the tip part of the capsule 10 is positioned in the inside of the tip part of a guide part 11 of a piercer body 17, and the vicinity of the tip of a hollow ring part 21 of the timing rod 19 abuts on the piercer body 17. The operator feels a resistance in the push operation by a resistance of the hollow ring part 21. In this case, when the push operation is further advanced, and the push force exceeds some value, the hollow ring part 21 is brought to elastic deformation, and pierced instantaneously into a hole part 22 provided on the front part of the timing rod 19. That is, said resistance is lost instantaneously, the whole operating part 15A intrudes forward, and the piercing pin 2 is pierced instantaneously into an earlobe.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention provides a method for piercing a wearer's earlobe with a piercing, temporarily wearing the earring, and making a hole in the earlobe for the piercing. This invention relates to an earlobe perforator for piercing.

More specifically, it holds a piercing body having a piercing pin and a plate part, and is provided with a capsule that is configured to be freely separable from the piercing body, and has the shape of an earlobe insertion part into which the earlobe is inserted; A perforator body is provided with a guide portion that guides the piercing pin into the earlobe insertion portion, and a push rod is provided for pushing the capsule so that the piercing pin advances into the earlobe insertion portion, and the piercing pin is moved based on the pushing operation of the capsule. This invention relates to an earlobe puncher for piercing an earlobe to make a hole for wearing earrings.

[Prior Art] Conventionally, as this type of earring tab puncher, there is one disclosed in Japanese Patent Publication No. 59-30401, for example. This piercing mm tab perforator is as shown in Fig. 7.8.
It is only necessary to provide a spring (40) that urges the push rod (15) back in the direction opposite to the direction in which the capsule (10) is pushed. The speed of operation was left up to the operator. That is, in the insertion stage of the pierce pin (2), the push rod (15) must be pushed against the biasing force of the spring (40), so the pierce pin (2) is inserted slowly at a relatively low speed. It was easy to put away.

[Problem to be solved by the invention] Now, considering the pain caused when piercing the earlobe with the piercing pin, it is found that it is much less painful if the piercing pin is pierced in a shorter time than if it is performed at a slower speed. Furthermore, since the piercing is worn on the earlobe, the wearer is likely to hear the piercing sound, and this operation is likely to be perceived and recognized, amplifying pain and anxiety. Become.

Now, in the above-mentioned conventional technology, since the perforator did not have a mechanical mechanism to actively assist the piercing speed of the piercing pin, the piercing pin was often inserted slowly, resulting in more insertion. It was supposed to cause pain and anxiety to the wearer.

An object of the present invention is to make it easier to pierce an earlobe with a piercing pin in a short time.

[Means for Solving the Problems] In order to solve the above-mentioned problems, in the piercing mm lobe puncher of the present application, the push rod is moved at a position where the piercing pin is almost close to the wearer's earlobe with respect to the movement of the earring body. The piercing pin is characterized by being provided with a resistor that provides resistance to the advancement of the pierce pin due to the pushing operation, and is configured to rapidly lose its resistance when a pushing force exceeding a predetermined value is applied.

[Function] In the above configuration, the piercing pin provides resistance to the movement of the piercing body at a predetermined position almost close to the wearer's earlobe, and also provides resistance against pushing force exceeding a predetermined value. Because the perforator is equipped with a resistor that loses rapidly, when the wearer pushes the push rod to push the piercing pin forward, the wearer will first feel resistance to the pushing operation of the push rod at a position close to the earlobe, and the tip of the piercing pin will begin to move forward. It was almost close to my earlobe, and I realized that it was about to be pierced. Here, this position can be easily determined from the positional relationship of each member of the piercing tool by knowing the average thickness of the earlobe. The wearer then increases the pushing force. When this strong pushing force is applied to the resistor, the resistor rapidly loses its resistance due to its structure. As a result, the push rod linked to this resistor can move forward easily, and the piercing pin is instantly pierced into the earlobe.
It will be penetrated.

[Effects] As explained above, the resistor allows the insertion of the piercing pin to be easily and instantaneously carried out, and as a result, the insertion of the piercing pin can be completed in a short period of time, resulting in more pain than in the conventional case. The present invention has made it possible to obtain a perforator that can perform perforations with peace of mind, without causing anxiety or hesitation that would cause the insertion to be stopped at the beginning or middle of the insertion operation.

In addition, as a preferred embodiment of the present application, the resistor includes an elastic hollow ring portion provided in a needle insertion rod connected to the push rod, and Assuming that the ring part can be inserted and is made up of a hollow part with a smaller diameter than the hollow ring part, after the hollow ring part undergoes elastic deformation in response to a pushing force of more than a predetermined value, Since the structure can be made to lose resistance, it is possible to achieve the above object with a simple structure.

[Example] Next, embodiments of the present invention will be described based on the drawings.
