Heretofore, the aforementioned type of loop pins have been known wherein an insertion portion having a splice portion formed on one end of a plastic wire is inserted, which is stretched such that it has an appropriate degree of elasticity and stiffness, to a sleeve-like receiving portion which is formed at the other end of the plastic wire and which has an impeding escape portion which is formed within the sleeve-like receiving portion, with the portion spliced with the preventive portion of escape. In known loop pins, these component parts are integral with each other. In former times, it was customary for such loop pins to be individually manufactured and used in their separate condition, not as a unit or set of pins. And when they were in use, manually attached tags were fastened manually, one by one, over the loop pins, to each trade product. This manual work lacked efficiency and required substantial time. In addition, due to the intense of their fingers, workers were exposed to workers' accidents such as tendovagunitis, etc. In such circumstances, in order to increase the efficiency of work, to reduce the time required for work and to reduce the burdens inflicted on workers, a loop fastener was recently developed in which a label can be attached to a product. of trading through a one-touch operation of wielding a lever. Simultaneously, a cartridge has also been developed in which the loop pins are arranged in series on a base member so that the loop pins can be sequentially loaded onto the loop pin holder. However, the conventional loop pin fasteners developed so far have shortcomings in the sense that the overall size has been increased due to the component parts of the construction of the fasteners, the feeding of the loop pins being loaded is not Stable in accuracy and reliability, and the cutting of the loop pins as a base cartridge is also not stable.

Its configuration in an area near its base end is rectangular and in an area near its distal end it is that of a circular end face. The receiving portion guide 39 is integrally provided with a holding plate 40 on a base end side of the base 39a. The receiving portion guide 39 is secured to the body case 2 so that the slot 39c corresponds to the belt member 37. A bent portion 39a is formed in the slit 39d to guide (pass) the string portion to the clip loop in an area in the vicinity of a distal end thereof, so that the receiving portion (female portion) of the link pin does not jump outwardly. The reference number 42 denotes a cutting element corresponding to the aforementioned reference number 21. The individual loop pins cut from the loop pin cartridge are fed into the insertion portion (male portion) and the receiving portion (female portion) through the respective mechanisms previously described. Finally, the insertion portion is inserted to lock on the receiving portion with a label attached to a product of a store. The reference number 43 denotes an auxiliary cover. This auxiliary cover 43 is provided with a generally L-shaped splicing portion 43 which is spliced to close with the cover 44 of the receiving portion guide 39. A receiving plate 45 is placed on the holding plate 40 and they are joined together with screws. A sectionally arcuate groove 45a for guiding the sliding part of the plunger rod 14 is formed on a side edge of the restriction plate 45. A hook 45b for engaging, for retention, a through hole of a label is formed on a end protruding from slot 45a. A fastener of a loop pin for hooking a label according to the present invention is constructed in the manner mentioned above. According to the above, a small size fastener can be achieved in comparison with conventional devices and more reliable feeding of the insertion portion and the receiving portion of the loop pin can be obtained. When the loop pins are in the form of a cartridge in loop pins, the cutting accuracy is increased and the loop pins are prevented from escaping from the holder during operation. In addition, a more uniform operation can be performed compared to the prior art. In particular, the insertion portion can be cut in advance, if necessary. In that case, the receiving portion can be pushed by the cutting force. Since the gear ratios are greatly different, a feeding operation with different time interval compared to the prior art can be obtained. Although the present invention has been described in the form of a preferred embodiment, the present invention is not limited to this embodiment. Many changes and modifications can be made by those skilled in the art without departing from the spirit and scope of the present invention as defined in the appended claims.
