DETAILED DESCRIPTION OF THE INVENTION The present invention arranges connected nails around the nose member of a nailing machine in which a rod-shaped nailing driver feeds the connected nails one by one into the nose member which is reciprocated. About Nail Magazine.

Conventionally, a large number of long nails are connected using a connecting wire, etc., and the upper part is -■-↓Z,±ι↓reyo±m yubure-yabure)Yjゝ,,bu is to swirl these connecting nails. The connected nails are wound into a shape and stored in a cylindrical nail magazine provided apart from the nose where the nails are driven, and connected nails are fed from this nail magazine toward the nose member along the nail guide plate by a nail feeding device. While feeding, nails are driven out one by one from the nose and driven into the material to be driven.

In this way, in conventional nailing machines, the nail magazine is fixedly installed on the nailing machine away from the nose, so the connecting nails have a long pull-out distance, and the overall structure of the nailing machine is not compact. There was a drawback that it took time and effort to attach the connecting nails to the nail magazine. SUMMARY OF THE INVENTION An object of the present invention is to provide a nail magazine in which the pull-out distance of the connecting nails is short and it is easy to set the connecting nails wound spirally around the nose member so that they can be driven. .

To achieve this object, the present invention has an upper lid part and a lower lid part, and has a peripheral wall around the periphery of these upper and lower lid parts, and forms a space in which the connecting nails are wound and stored in a spiral shape. Then, a cylindrical nail feeding guide is provided between the centers of the upper and lower cover parts, a nail feeding slit is formed in a part of this nail feeding guide, and the connecting nail is fed into the nail feeding card. An elastically supported guide mounting piece is bent at one end of the nail feeding guide that forms the feeding slit, and a portion of the guide mounting piece is connected to the second or subsequent nails from the beginning. The gist is that a nail hooking piece for hooking at least one nail located at the nail is formed so as to protrude inwardly from the nail feeding guide. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to FIGS. 1 to 3.

Before explaining the nail magazine 9 of the present invention in detail, the main points of the nail gun 1 to which this nail magazine 9 is attached will be explained as follows. That is, a striking cylinder 3 is built into the body 2 of the nailing machine 1, and a striking piston (not shown) is slidably and tightly fitted into the striking cylinder 3. The driving method for this striking piston may be any conventionally commonly used method. A rod-shaped driver 4 is rigidly connected to this striking piston. A bottom plate portion 5 that closes the bottom of the body 2 and the impact cylinder 3 and a nose member 6 are integrated. A driver guide hole 7 through which the driver 4 reciprocates is formed inside the nose member 6 . The outer surface 6a of the nose member 6 is provided with a guide means for guiding the nail magazine 9 in the longitudinal axis direction of the nose member 6 when the cassette-type nail magazine 9 is installed, and a guide means for guiding the nail magazine 9 in the longitudinal axis direction of the nose member 6.

A nail feeding turret 8 is attached to the bottom plate portion 5 on one side of the nose member 6 (on the right side of the nose member 6 in FIG. 1).
It is rotatably supported by a bearing surface 15 projecting downward and a bearing part 16 projecting laterally from the nose member 6 below the nose member 6. ing.

A nail magazine mounting guide 17 having a wing-shaped cross section is provided on the side of the nose member 6, facing the nail feed turret 8, and fixed to the bottom plate portion 5. One end 17a of this nail magazine mounting guide 17 on the side closer to the nose member 6 is bulged. The other end 17b on the side far from the nose member 6 is formed in a wedge shape. The nail magazine mounting guide 17 is arranged so that the distance between the nail magazine mounting guide 17 and the nail feed turret 8 becomes gradually narrower as the nail magazine mounting guide 17 approaches the nose member 6 as a whole.
A cassette type nail magazine 9 of the present invention is mounted around the nose member 6.

This nail magazine 9 is made of synthetic resin and has a wide cylindrical shape with an upper lid part 10 and an inclined lower lid part 11. A connecting nail 14, which is a plurality of nails 13 connected in parallel by a connecting wire 12, is wound spirally and stored in a space formed between the upper lid part 10, the lower lid part 11, and the peripheral wall 9a. This connecting nail 14 can be stored in the nail magazine 9 by removing the upper cover part 10 or the lower cover part 11. A nose member 6 is provided on the upper inner wall surface 20 of the upper lid portion 10.
It is tapered so that it gradually decreases toward . The taper of this upper inner wall surface 20 is such that each nail 13 constituting the connecting nail 14
This corresponds to winding the entire connecting nail 14 in a spiral shape while gradually lowering the expanding diameter head portion 22 toward the center of the spiral so that the expanding diameter head portion 22 does not collide with the side surface of the expanding diameter head portion 22. It is something to do. Lower inner wall surface 2 of lower lid part 11
3 is also tapered so as to gradually decrease toward the nose member 6.

Thereby, the lower lid part 11 can completely support the entire toe part of the connecting nail 14. At the center of the nail magazine 9, a substantially cylindrical nail feeding guide 18 is provided which accommodates the nose member 6, nail feeding turret 8, and nail magazine mounting guide 17 therein.

A part of this nail feeding guide 18 is shown in FIGS. 2 and 3.
As shown in the figure, the nail 1 in the center of the spiral in the connecting nail 14
