Description

Piercing hole punch

The present invention relates to a technical field of a piercing hole punch for making a piercing hole in a human body such as an earlobe.

In general, as this type of piercing hole punch, for example, when trying to attach a piercing to an earlobe, the piercing needle is instantaneously ejected using the biasing force of an ammunition, and the piercing needle penetrates the earlobe. There is known a piercing hole punch for piercing a piercing hole.
Among these, in order to fire the piercing needle in a stable state and to pierce the piercing hole in an accurate position and direction, there is one in which the piercing needle is fired in a state where the punch is held between the ear lobes. As such a piercing hole punch, a piercing needle holding body loaded with a piercing needle, a catch holding body loaded with a catch detachably locked to the piercing needle, and an operation body for firing the piercing needle In the state where a human body local area to be drilled is inserted between the piercing needle holder and the catch holder, the gap between the two holders (pierce needle and catch) and the human body local area is eliminated. In this state, the piercing hole is perforated by operating the operating body and firing the piercing needle (see, for example, Patent Documents 1 and 2).
In Patent Document 1, a movable body in which a catch is incorporated moves back and forth with respect to a punch body in which a piercing holder holding a piercing needle is incorporated, and the movable body is opposed to an ammunition. Then, by moving to the punch body side, the space between the punch body side and the movable body side is narrowed so that the local part of the human body is sandwiched.
Further, in Patent Document 2, a gap is formed between the movable body and the perforator body by separating the movable body incorporating the catch from the perforator body against the ammunition, and a human body is formed in the gap. The earlobe is sandwiched between the movable body and the punch body by moving the movable body toward the punch body by the urging force of the ammunition in a state where the local portion is inserted.

JP-A-9-19312 JP 2011-245221 A

However, since the thing of the said patent document 1 requires the movable body in which the catch was incorporated with respect to the punch main body, and the bullet machine for energizing this movable body as separate parts, the part number is equivalent. In addition to the problem that it increases, there is an additional problem that the operability is inferior because it requires a double operation of firing the piercing needle while maintaining the state where the movable body is moved and operated against the ammunition. .
On the other hand, since the thing of patent document 2 urges | moves a movable body to the punch body main body side via an ammunition, and pinches a human body local part by this urging | biasing force, when launching a piercing needle, Double operation is not required unlike the one in the literature 1, but a movable body incorporating a catch and an ammunition for energizing the movable body are required as separate parts, which increases the number of parts. There are still problems to be solved, and there are problems to be solved by the present invention.

Next, embodiments of the present invention will be described with reference to the drawings. In describing this embodiment, for the sake of convenience, the upper side in FIG. 1B is up (planar), the lower side is down (bottom surface), the right side is front (front), the left side is rear (rear), and the front side The right side (right side) and the back side left (left side) will be described. However, it is needless to say that these directions are not limited thereto.
In the drawings, reference numeral 1 denotes a piercing hole punch. The piercing hole punch 1 includes a main body 2 of a box-shaped punch 1 having a concave shape (see FIG. 1B) when viewed from the right side, and a piercing needle 3. And a piercing holder 4 that accommodates.
The main body 2 is formed as a substantially rectangular shape by abutting and assembling the half-shaped case bodies A and B, and these case bodies A and B are fitted into male and female when they are abutted with each other. (Not shown) so that they are integrated in an aligned state, but are basically symmetrical. For the integration of the case bodies A and B, a generally known method such as an adhesive or adhesion by ultrasonic fusion can be further employed.

Next, the main body 2 in a state where the case bodies A and B are assembled will be described in detail.
The main body 2 is divided into the following chambers by walls. 2 and 4, the release chamber 5 formed in the lower right portion, the shaft chamber 6 formed in the upper right portion (upper right portion of the release chamber 5), and the upper central portion (left side of the shaft chamber 6) The pierce holder chamber 7 is formed, and a catch chamber 8 is formed at the left end portion (left side of the release chamber 5 and the pierce holder chamber 7).

The release chamber 5 is a room provided with a release (corresponding to the “operating body” of the present invention) 9 that is operated when a piercing needle 3 described later is fired. The circular part 5b and the convex part 5c form a key hole 5d.
On the other hand, the release 9 has a long cylindrical shape in the front-rear direction, and in the initial posture at the time of purchase of the piercing hole punch 1, the front end portion 9a of the release 9 passes through the key hole 5d and exits from the release chamber 5. The locking projection 9b formed on the outer peripheral surface of the protruding release front end 9a is displaced from the keyhole projection 5c, whereby the release 9 is locked. The convex portion 9b is configured to be engaged with the peripheral portion of the circular portion 5b of the key hole 5d from the outside, so that it does not inadvertently enter the key hole 5d.
Furthermore, a large-diameter portion 9c having a larger diameter than the other portions is formed in the middle portion of the release 9, but the rear end side surface 9d of the large-diameter portion 9c is narrower toward the rear end side. The inclined surface 9d is inclined.
Further, the rear end portion 9e of the release is slidably held by a holding portion 5f protruding from the left and right bottom surfaces of the release chamber 5. In the initial posture, the rear end portion 9e is disposed behind the holding portion 5f and the inclined surface 9d. A gap corresponding to the plate thickness of a stopper (corresponding to a “regulating member” of the present invention) 10 to be described later is secured between the ends.
Then, when firing a piercing needle 3 to be described later, the locking projection 9b is rotated around the axial center so as to reach the keyhole projection 5c position to a firing ready posture (see FIG. 5C), In this state, by pushing the release front end 9a into the main body 2, the release 9 can be moved backward.
Reference numeral 5e denotes a positioning protrusion for positioning the rotated locking protrusion 9b so as not to rotate beyond the position of the keyhole protrusion 5c.

The shaft chamber 6 is a chamber for firing a cylindrical shaft (corresponding to the “moving member” of the present invention) 12 by pushing the release 9. The shaft chamber 6 is an intermediate position in the front-rear direction. The front and

rear shaft chambers

6b and 6c are partitioned by a first partition wall 6a provided on the front and

rear shaft chambers

6b and 6c. The front and

rear shaft chambers

6b and 6c are arc-shaped first through holes 6d provided in the first partition wall 6a. It is in a state of communication by.

The stopper 10 is formed in a plate shape that is long in the vertical direction, but in the second partition wall 2a in which the vertical middle portion partitions the space between the release chamber 5 and the shaft chamber 6, the first partition wall 6a is opposed to the first partition wall 6a. Thus, the stopper 10 is configured to extend over the release chamber 5 and the front shaft small chamber 6b.
A release-side through hole 10a having a size through which the release large-diameter portion 9c can pass is formed at the lower end of the stopper 10 on the release chamber 5 side. 10 is in the upward movement position, and the release 9 penetrates the release side through hole 10a in a state where the lower end portion of the release side through hole 10a abuts the rear end of the inclined surface 9d of the release large diameter portion 9c.
Further, a shaft side through hole 10b similar to the first through hole 6d provided in the first partition wall 6a is provided at the upper end portion of the stopper 10 on the front shaft small chamber 6b side. The shaft side through hole 10b moves upward until reaching the firing preparation completion posture at the upward movement position, and thereby the stopper 10 blocks (narrows) a part of the first series of through holes 6d.

The shaft chamber 6 is provided with a long shaft 12 extending in the front-rear direction passing through the first through hole 6d provided in the first partition wall 6a and the shaft side through hole 10b of the stopper 10 in a loosely fitting manner. At the middle part in the front-rear direction of the shaft 12, a bullet receiver 12a that receives the rear end of the bullet 11 installed in the front shaft chamber 6b is formed in a large diameter, but the outer diameter of the bullet receiver 12a is The inner diameter of each of the first series of through holes 6d and the shaft side through hole 10b is smaller. Until reaching the firing preparation completion posture, the ammunition receiver 12a is located at the peripheral portion of the first through hole 6b of the stopper 10 in the upward movement position and blocking a part of the first through hole 6d. By this, the shaft 12 receives the urging force of the bullet machine 11 to momentarily launch and move to the rear side so as to be freely disengaged.

Next, the pierce holder chamber 7 is partitioned from the rear shaft small chamber 6c through the third partition wall 2c. The shaft 12 passes through the third partition wall 2c, but the machine receiver 12a passes through. The 2nd communicating hole 2d of the magnitude | size which does not carry out is opened.
The pierce holder chamber 7 includes a halved pierce holder 4 that is movable in the front-rear direction. The pierce holder 4 has a pierce needle 3 therein and is arranged vertically symmetrically. The paired

holder halves

4a and 4b are formed in a substantially rectangular shape by abutting from above and below.

As shown in FIG. 3, the piercing holder 4 includes a semi-cylindrical body portion 4 d provided with a housing groove 4 c for housing the head portion 3 a of the piercing needle 3 and the rear half portion of the needle portion 3 c of the piercing needle 3. An extension portion 4e formed to extend in an arc shape from the center position in the left-right direction at the rear end of the main body portion 4d, and a needle tip portion 3b of the piercing needle at the end of the extension portion 4e. It comprises a needle tip cover cover portion 4f for covering, and an operation protrusion 4g that protrudes in the left-right direction from the left and right split surface portions (vertical center positions of the left and right ends) of the main body portion 4d.
The needle tip cover 4f is abutted against each other so that the needle tip 3b of the piercing needle 3 held by the piercing holder 4 is not exposed when the

holder halves

4a and 4b are abutted. When the piercing needle 3 is assembled into the piercing holder 4, the tip of the needle tip portion 3b is assembled with the end of the needle tip cover portion 4f on the piercing holder chamber 7 side, that is, in a state of being flush with each other. Thereby, the elastic movement allowance of the needle tip cover portion 4f until the tip of the needle tip portion 3b comes into contact with the skin surface is ensured by the thickness of the needle tip cover portion 4f. Of course, the position of 3b can be set so as to be shifted before and after the end of the needle tip cover 4f on the pierce holder chamber 7 side.
Incidentally, the extending portion 4e is elastically deformed to elastically move the needle tip cover portion 4f as will be described later, but for this purpose, the shape is not limited to a shape that bulges outward, for example, a square shape, Of course, it may be U-shaped and the bulging direction may be inside.
A through-hole 4h through which the needle tip 3b of the piercing needle 3 held by the piercing holder 4 can be seen from the catch side is formed on the front surface (side surface of the piercing holder chamber 7) of the needle tip cover 4f. The through hole 4h has the same diameter as that of the needle portion 3c but a larger diameter than the diameter, but is smaller than the head portion 3a.
The operation protrusion 4g is fitted in the guide hole 7a so as to be slidable in the front-rear direction with the tip protruding from the guide hole 7a formed on the left and right side surfaces of the pierce holder chamber 7, and the operation protrusion 4g. The piercing holder 4 is configured so that the piercing holder chamber 7 can be moved and adjusted in the front-rear direction by moving the piercing holder 4 forward and backward by placing a finger on the head (see FIG. 5A).
The sliding contact surface between the pierce holder chamber 7 and the holder body 4d is a serration groove (not shown: a small wavy groove in the present embodiment, which corresponds to the “resistance treatment” of the present invention. Are formed with each other, and when the piercing holder 4 is moved, the pierce holder 4 is moved over the mountain to give a feeling of moving operation of “rich, rich ...” and the piercing holder 4 slides against the piercing holder chamber 7. A resistance is given to dynamic movement, and the piercing holder 4 can be prevented from being inadvertently returned when a launch preparation completion posture described later is obtained. The resistance treatment is not limited to the serration groove X. Usually, a sliding pattern is applied to the sliding contact surface to give sliding resistance, or a light press-fitted state is given to give sliding resistance. A known resistance application process can be employed.

In the initial posture in which the piercing holder 4 is accommodated in the piercing holder chamber 7, there is a gap between the needle tip cover 4 f and the catch chamber 8, which will be described later, for loosely fitting the earlobe E, which is a local part of the human body to be drilled. S is secured.
Incidentally, in the present embodiment, in order to visually observe the main body portion 4d of the pierce holder 4 held in the pierce holder chamber 7 in the pierce holder chamber 7, in the present embodiment, it is a long hole that is long in the front-rear direction. A window 7b is formed. By looking into the viewing window 7b from the outside, the state (color, shape, etc.) of the head portion 3a of the piercing needle 3 held by the piercing holder 4 through the body portion 4d formed of a colorless and transparent resin material can be visually recognized. It has become.

The catch chamber 8 is a chamber that accommodates a catch 13 for inserting and supporting and fixing the piercing needle 3, and is formed to protrude rearward from the release chamber 5 in a substantially L shape, In the catch chamber 8, a locking groove 8a for locking the catch 13 is cut out in the left-right direction.
The catch 13 is accommodated by detachably locking the large-diameter tip 13a of the catch 13 in the locking groove 8a.

Next, a procedure for drilling a pierced hole in an earlobe or the like using the pierced hole punch 1 of the present invention will be described.
First, in the initial posture at the time of purchase of the piercing hole punch 1 shown in FIG. 5 (A), the release 9 is released by locking the locking projection 9b of the front end 9a from the outside to the key hole 5d. It is in a state of protruding outward from the chamber 5. At this time, the stopper 10 is in an upward movement position where the upper surface abuts on the upper side wall 6e of the front shaft chamber 6b, the rear end of the release 9 inclined surface 9d is locked to the release side through hole 10a, and the shaft 12 The receiver 12a is locked in the shaft side through hole 10b. Furthermore, the piercing holder 4 is accommodated so as to abut on the third partition wall 2 c that is the front end in the piercing holder chamber 7. And by these, in the initial posture, the movement of the release 9 and the shaft 12 is restricted, and the piercing holder 4 is configured not to fire.
In this initial state, the earlobe E is loosely fitted into the gap S between the earring holder 4 and the catch chamber 8, and the rear surface of the earlobe E is brought into contact with the front end 8 b of the catch chamber 8.

Next, as shown in FIG. 5 (B), the operation protrusion 4g of the piercing holder 4 is slid rearward, and the earlobe E is sandwiched between the needle tip cover 4f and the catch chamber front end 8b. The hole punch 1 is in the initial posture of the pinching posture.
Moreover, in the present embodiment, the center part of the visual groove 4h provided at the rear end of the needle tip cover part 4f (because the pierce holder 4 is transparent, the central part of the groove hole can be confirmed). Therefore, the user can confirm the drilling position by visual or tactile sense. Then, as shown in FIG. 5C, when the piercing holder 4 is further moved to the catch chamber 8 side from this state, the extension portion 4e is elastically deformed so as to expand, and the needle tip cover portion 4f is pierced. The piercing punch 1 is held by the earlobe E in a pressed state by the restoring force exerted at this time. The elastic movement amount of the needle tip cover 4f at this time is preferably up to a position immediately before the needle tip abuts on the earlobe E. By moving in this way, the piercing position by the piercing punch 1 is changed. When the device 1 is held by the earlobe E, the movement can be adjusted without damaging the earlobe E.

Thereafter, as shown in FIG. 5C, the release front end portion 9a is rotated around the axis while the ear pinching state between the piercing holder 4 and the catch chamber 8 is maintained, and the locking convex portion 9b becomes the keyhole. By reaching the position of the convex portion 5c, it becomes a ready posture for launching. Only when this ready-to-fire posture is achieved, the release 9 can be pushed backward.

Next, as shown in FIG. 5 (D), the release front end portion 9a is pushed backward from the keyhole 5d from the posture ready for launch, and the release 9 moves backward by this pushing operation. As a result, the release large-diameter portion inclined surface 9d that abuts the lower end portion of the release side through hole 10a of the stopper 10 in the downward direction moves rearward while moving the stopper 10 downward. 10 moves downward and becomes a downward movement position. At this time, since the stopper 10 is supported by the holding portion 5f, the stopper 10 is restricted from moving backward in conjunction with the movement of the release 9, and can surely move downward. The release 9 is also configured such that when the inclined surface 9d moves to the front end surface of the holding portion 5f, the release 9 does not move further rearward.
As the stopper 10 moves downward, the shaft-side through hole 10b of the stopper 10 moves downward to communicate with the first series of through holes 6d. The shaft 12 receives the urging force of the bullet machine 11 and thereby instantaneously fires backward, and the bullet holder 12a is inserted into the second communication hole 2d opened in the third partition wall 2c. It will move instantaneously backward until it locks.
Then, the rear end of the shaft 12 pops out from the second communication hole 2d, so that the piercing holder 4 is instantaneously pushed backward from the piercing holder chamber 7 by an instantaneous force and moved to move. The piercing needle 3 passes through the earlobe E. At this time, as the piercing holder 4 is pushed out of the piercing holder chamber 7, the

holder halves

4a and 4b are divided into upper and lower parts, and the piercing needle 3 With the tip 3b exposed, the piercing needle 3 pierces the earlobe E, and the tip 3b fits and locks into the catch 13 so that the piercing hole punch 1 is fired after firing shown in FIG. Become posture.

When the perforation of the earlobe E is completed in this way, the main body 2 is moved downward, and the catch 13 is extracted from the catch holder chamber 8, thereby completing the perforation of the pierce holes to the series of earlobe E.

In this embodiment, after setting the pinching posture, the release front end portion 9a of the release 9 is rotated around the axis so that the locking projection 9b reaches the position of the keyhole projection 5c. In order to prevent inadvertent firing due to an erroneous operation of the release 9, the piercing hole punch 1 in a state in which the release 9 is rotated in advance around the axis so that the locking projection 9 b reaches the keyhole projection 5 c position. Can be put into the pinching posture after being applied to the earlobe E, so that the pinching posture can be used as the firing preparation complete posture as it is.

In the embodiment of the present invention configured as described above, the punch body 2 constituting the piercing hole punch 1 includes a piercing holder 4 holding a piercing needle 3 necessary as a component of the piercing hole punch 1, a catch 13, the shaft 12, the bullet machine 11, the stopper 10, and the release 9 are all integrated, and a catch receiver in which the catch 13 is incorporated is movably provided to the main body 2 as in the past. A catch receiver as a separate member is not required as in the case of a thing, and the number of parts can be reduced accordingly.

Then, from the main body portion 4d of the piercing holder 4 slidably incorporated in the piercing holder chamber 7 formed in the main body 2, the needle tip cover lid portion 4f is formed through the extending portion 4e, and the needle tip 3b is not exposed. Therefore, it is possible to prevent a finger from inadvertently touching and damaging the needle tip portion 3a or soiling the needle tip portion 3a.

On the other hand, in order to pierce the earlobe E with the earring needle 3, the earring E is loosely fitted in the gap S between the needle tip cover 4f and the catch chamber 8, and a finger is attached to the operation protrusion 4g. The holder 4 is slid to the catch chamber 8 side, the piercing holder 4 is further moved to the catch chamber 8 side from the posture in which the earlobe E comes into contact with the needle tip cover 4f and the catch chamber 8, and the needle tip 3b is moved to the earlobe E. The needle tip cover 4f is elastically moved toward the pierce holder chamber 7 due to the elastic deformation of the extension 4e, and the piercing punch is received by this restoring force. 1 is held in a state in which the earlobe E is pressed (restrained). In this state, the piercing adjusts the drilling position by l3, and then the release 9 is rotated around the axis so that the locking projection 9b coincides with the key hole 5d of the release chamber 5.
When the piercing needle 3 is ready to be fired in this way, when the front end portion 9a of the release 9 is pushed with a finger, the stopper 10 moves, and thereby the movement restriction of the shaft 10 by the stopper 10 is released. The shaft 12 is instantaneously fired toward the piercing holder 4 under the urging force of the bullet machine 11. When the fired shaft 12 collides with the piercing holder 4, the piercing l3 pierces the earlobe E and locks to the catch 13 in time with the piercing holder 4 firing from the piercing holder chamber 7.

In the present invention, the holding force of the piercing punch 1 with respect to the earlobe E is obtained by using the restoring force accompanying the elastic movement of the needle tip cover 4f. The pierced earring 11 receives the urging force of 11, and the l3 instantaneously forms a pierced hole in the earlobe E, but the catch receiver is moved as in the prior art, and the earlobe is sandwiched between the catch receiver and the main body side. Like a thing, the ammunition for forcibly moving a catch receptacle becomes unnecessary, and the number of parts can further be reduced by that much.
Incidentally, since the magnitude of the holding force of the piercing punch 1 with respect to the earlobe E changes depending on the elastic movement amount of the needle tip cover 4f, it is a part of the holding force when the movement amount is small, If it is large, all of the holding power can be exhibited.

In this case, a guide hole 7 a is formed in the pierce holder chamber 7 so that the operation protrusion 4 g protruding from the pierce holder 4 is movably guided, and the operation protrusion 4 g is operated from outside the pierce holder chamber 7. Since the piercing holder 4 can be slid, the piercing holder 4 can be moved with good operability.

In addition, the needle tip cover 4f is formed with a through-hole 4h having the same diameter as or larger than the needle 3c of the piercing needle 3 and a smaller diameter than the head 3a. When penetrating E, the needle tip cover 4f does not interfere with the movement of the needle portion 3c, and the penetrating position of the needle portion 3c is not shifted, and the head portion 3a having a larger diameter than the through hole 4h is formed in the through hole. By hitting 4h, the

holder halves

4a and 4b are separated so that they can be flipped, and the

holder halves

4a and 4b do not interfere with the penetration of the earlobe E.

Further, the piercing needle 3 has a needle tip 3c that is flush with the pierce holder chamber side end of the through-hole 4h, that is, flush with the pierce holder chamber side end of the needle tip cover portion 4f. A large holding force for the earlobe E of the piercing punch 1 can be ensured as an elastic movement allowance to the piercing holder chamber 7 side of the needle tip cover until the needle tip 3b hits the skin. However, since the needle tip 3b is inserted into the through-hole 4h in this holding state, it is possible to prevent the piercing needle 3 from being displaced during firing.
Moreover, at the time of launching, the movement of the piercing holder 4 moves the needle tip cover portion 4f further relative to the piercing holder chamber 7, so that the holding force of the earlobe E by the needle tip cover portion 4f is strengthened and the earlobe E is inadvertently moved. And the drilling to the target position becomes more reliable.

In addition, in this case, since the resistance treatment for giving the sliding resistance to the sliding contact surface between the pierce holder chamber 7 and the holder main body portion 4d is performed, the needle tip cover lid portion 4f is caught in the catch chamber as described above. When the piercing hole punch 1 is held on the earlobe E based on the elastic movement of the needle tip cover portion 4f accompanying the movement to the side 8, the needle tip cover portion 4f receives the restoring force and the needle tip cover portion 4f receives the piercing holder chamber 7 It is possible to prevent the holding force from being lowered by moving back to the side, so that the holding can be surely performed.

Of course, the present invention is not limited to the first embodiment, and may be configured as the second to fourth embodiments shown in FIGS. 6 to 8, for example. . Detailed descriptions of the same functions and configurations as those of the first embodiment are omitted.

The piercing hole punch 21 according to the second embodiment shown in FIG. 6 includes an operation projection 24g provided on a piercing holder 24 composed of a pair of

holder halves

24a and 24b arranged vertically symmetrically. The point provided on the upper surface of the upper holder half 24a instead of the part is different from the first embodiment. The operation protrusion 24g is fitted in the guide hole 27a so as to be slidable in the front-rear direction with the tip protruding from the guide hole 27a formed on the upper surface of the pierce holder chamber 27 provided in the main body 22. Thus, the piercing holder 24 moves in the piercing holder chamber 27 in the front-rear direction, and is configured to be in an ear pinching position.

In addition, the pierce holder 24 has a recess 24c formed in the upper holder half 24a, and a protrusion 24d that is loosely fitted in the recess 24c in the lower holder half 24b. Thus, even if the operation projection 24g protrudes only on the upper side surface of the pierce holder chamber 27, the upper and

lower holder halves

24a and 24b are misaligned in a state where the upper and

lower holder halves

24a and 24b are in contact with each other. The operation projection 24g can be easily moved in the front-rear direction.

Further, in the third embodiment shown in FIG. 7, the extending portion 34e of the piercing holder 34 protrudes in the left-right direction, and can be implemented in this way.

Furthermore, the thing of 4th Embodiment shown in FIG. 8 integrates the release which is an operation tool, and the stopper which is a control member. That is, only the through-hole 410b on the shaft 412 side is formed in the stopper portion 410, but the through-hole 410b is biased downward with respect to the first series of through-holes 46d and is engaged with the bullet receiver 412a. It has stopped.
On the other hand, the release portion 49 integrated with the lower end portion of the stopper portion 410 penetrates downward from the through hole 422b provided in the lower end portion of the punch body 42, has a flange shape, and penetrates the through hole 422b. In the initial posture (see FIG. 8A), the peripheral portion of the operation portion 49a having a possible shape is locked to the peripheral portion of the through hole 422b from below. In this state, the piercing holder 44 is moved to hold the piercing hole punch 41 on the earlobe, and then the operation unit 49a is moved rearward to obtain a ready-to-fire posture (see FIG. 8B).
When the operating portion 49a is pushed upward from this posture, the through-hole 410b moves upward and communicates concentrically with the first series of through-holes 46b, and the lock of the bullet receiver 412a is released. As a result, the shaft 412 is fired under the urging force of the bullet 411 so that the earlobe can be pierced by the piercing needle 43.
And in what was done in this way, since the release which is an operation tool, and the stopper which is a control member are integrated, the reduction of the number of parts can further be aimed at.

The present invention can be used in the field of a piercing hole punch for punching a piercing hole in a local body part such as an earlobe.
