Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a magazine for a driving machine that houses a plurality of connected fasteners wound in a spiral shape.

[0002]

[Prior art]

 Generally, several kinds of connecting stoppers 9 having different stopper lengths are used in one driving machine, and therefore a magazine 1 capable of changing the supporting height of the foot portion of the connecting stopper 9 is required. However, as an example thereof, there is Japanese Utility Model Application Laid-Open No. 62-161981 filed by the applicant earlier. Hereinafter, this structure will be described with reference to FIGS. A conventional magazine 1 is composed of a bottom lid 3 that is openably and closably supported by the magazine 1, a nail holder 6 that supports the toes of a stopper 9, a holder shaft 2 that changes the support height of the nail holder 6, and the like. To be done. The holder shaft 2 stands upright at 90 ° above the bottom cover 3 and is fastened to the bottom cover 3 with screws 4 and nuts 5.

A plurality of locking recesses 10 having different heights are provided on the outer peripheral portion of the holder shaft 2 in parallel with the surface of the bottom lid 3, and the holder shaft 2 is prevented from rotating in the longitudinal direction. The groove 11 is formed. Further, as shown in FIGS. 5 and 6, a width across flats 12 is formed in parallel on both side surfaces of the anti-rotation groove 11 in the direction of 90 ° rotation. On the other hand, as shown in FIGS. 5 and 6, a locking projection 13 is mounted on the inside of the nail holder 6, and an inwardly projecting projection 14 is provided on the outer periphery of the nail holder 6 immediately above. The ring-shaped elastic body 15 is attached. The projecting portion 14 projects from the through window 16 formed in the nail holder 6 to the inside of the nail holder 6.

[0004]

[Problems to be solved by the device]

 In the conventional magazine 1, since the screw 4 penetrates the center of the holder shaft 2 and is fastened to the bottom lid 3 with the nut 5 arranged at the top of the holder shaft 2, the screw 4 will be screwed if the holder shaft 2 is long. There was a problem that it became long and costly. Further, when the stopper 9 is loaded, it is necessary to attach a holder cap 7 to be described later to the upper end of the holder shaft 2 in order to prevent the toes of the stopper 9 from being caught on the open upper surface of the holder shaft 2. In this case, since the holder cap 7 cannot be attached until the nail holder 6 and the holder shaft 2 are fastened to the bottom cover 3, the workability of assembling the holder cap 7 is poor. The object of the present invention is to solve the above-mentioned problems, to enable the holder shaft and the bottom lid to be fastened with a short screw, and to attach the holder cap to the holder shaft before fastening the bottom lid, thereby increasing the magazine height. It is to improve the workability of the work of adjusting.

[0005]

[Means for Solving the Problems]

 The above object is achieved by providing a nut insertion recess in the middle of the holder shaft.

[0006]

[Action]

 The holder shaft configured as described above can be fastened to the bottom lid with a certain screw regardless of the length of the holder shaft. Also, since the insertion position of the nut can be seen, it can be fastened to the bottom cover even after the holder cap, nail holder, and holder shaft are assembled.

[0007]

【Example】

 An embodiment of the present invention will be described with reference to FIGS. A plurality of locking recesses 10 are provided on the outer periphery of the holder shaft 2 along the axial direction, and the ring-shaped elastic body 15 is engaged with the outer periphery of the lower part of the recesses 10 to prevent the holder shaft 2 from rotating. A rotation preventing groove 11 is formed. A recess 17 into which the nut 5 can be inserted is formed at an intermediate position of the holder shaft 2. Further, a hole for inserting the screw 4 is formed between the lower end of the holder shaft 2 and the recess 17. The holder shaft 2 is fastened to the bottom lid 3 via screws 4 and nuts 5.

A nail holder 6 which is composed of a bottom plate parallel to the bottom lid 3 and a cylinder extending upward from the center of the bottom plate and capable of moving up and down along the holder shaft 2 is projected inward toward the lower side of the cylinder. The locking projection 13 is provided. Therefore, by moving the nail holder 6 up and down and engaging the projection 13 with the arbitrary engaging recess 10, the nail holder 6 can be engaged at a position corresponding to the length of the stopper 9 used. Yes, the height of magazine 1 can be adjusted. The upper end of the cylinder of the nail holder 6 is closed by a holder cap 7 to prevent the foot of the stopper 9 from being caught on the upper surface of the nail holder 6 when the stopper 9 is loaded.

As a result of the above configuration, as shown in FIG. 3, the holder shaft 2 can be fastened to the bottom cover 3 even after the holder shaft 2, the nail holder 6 and the holder cap 7 are assembled. Therefore, the workability can be improved. Further, the holder shaft 2 becomes longer as the length of the stopper 9 used becomes longer, but the screw 4 for fastening to the bottom cover 3 can be a screw having a much shorter length and is commonly used. It is possible to use screws that can be used, and it becomes possible to prevent the cost from rising.

[0010]

[Effect of device]

 According to the present invention, since the nut can be inserted into the middle portion of the holder shaft, a short screw can be used regardless of the length of the holder shaft. Also, since the position where the nut is inserted can be seen during assembly, it can be fastened to the bottom lid even after the nail holder, holder shaft, and holder cap have been assembled.
