Abstract

PURPOSE:To surely prevent the movement of up-and-down and right-and-left, and to prevent a pin from falling off from a personal ornament-putting on hole even at violent actions, by a method wherein the pin closely inserted into a cylindrical part is held by spring force in the cylindrical part, and two front and rear points on the other end side thereof are held between two pairs of holding pieces. CONSTITUTION:After a pin 7 is inserted into a pierced earring-putting on hole on an earlobe, the pin 7 is fitted to be fixed into the pierced earring-putting on hole. At that time, since a taper-shaped inserting part 12 expanded is at the inlet of a cylindrical part, the pin 7 is smoothly fitted, and can be pushed against the rear side of the earlobe. Since slits 13 are also on the cylindrical part 11, the pin 7 is elastically held by spring force of the cylindrical part 11, and is not slid. Furthermore, two front and rear points on the other end side of the pin 7 fitted into the cylindrical part 11 are, from the four quarters, held between two front and rear pairs of holding-pieces 14a, 14'a, 15a, 15'a, which are bent in the backward direction of the cylindrical part 11, and are strongly held by multi-point contact, and thus the up-and-down and right- and-left movement can be surely prevented. Even at violet actions, therefore, the pin 7 is prevented from falling off from the pierced earring-putting on hole on the earlobe.

。(Prior Art) Conventionally, as shown in FIG. 5, a cylindrical part 3 having an inner dimension into which a pin 7 can be inserted is provided in the center of a base plate 2 as a fastening tool for jewelry. Both ends 4 facing
A pin 7 is provided on the protruding side of the cylindrical portion 3 with bent pieces 5 that spring into contact with each other on the center line of the cylindrical portion 3, and a pin 7 into which the cylindrical portion 3 is fitted.
A fastening tool for jewelry has been proposed in which the holder is held between bent pieces 5. , (as a prior art document
There is a publication No. 414. ) (Problems to be Solved by the Invention) By the way, the above-mentioned conventional fastening tool for jewelry has a problem in that the cylindrical portion 3 is fitted onto the pin 7 inserted into the mounting hole of the jewelry, and the cylindrical portion 3 is attached to the pin 7. The pin 7 is not held sufficiently by just guiding the pin 7. That is, the pin 7 is held just behind the cylindrical portion 3 by the bent piece 5.
Since the pin 7 is only held between the pins 7 and 7, it is possible to prevent the pin 7 from swinging only in the vertical direction, but not in the left and right directions. Furthermore, in the case of violent movement, the cylindrical portion 3 slides without being able to prevent vertical vibration, and the pin 7 comes out of the attachment hole of the accessory.

Since it has a tapered introduction part that widens at the entrance, it can be smoothly fitted and pressed against the back side periphery of the mounting hole. Further, since this fitted fastener has a slit in the cylindrical portion, the pin is elastically held by the spring force of the cylindrical portion and does not slide. Furthermore, the front and rear ends of the other end of the pin that is fitted through the cylindrical part are held horizontally and vertically by two pairs of front and rear clamping pieces curved at the rear of the cylindrical part, and are held firmly by multi-point contact. ,
It can reliably prevent the pin from swinging up and down and left and right. Therefore, even in the case of violent movements, the pin will not come out from the attachment hole of the accessory.
