[Prior art]

 2. Description of the Related Art Conventionally, a handy type nail driver that uses compressed air or the like as a drive source is known. The main body of this nailing machine is provided with a protruding nose that serves as a nailing-out portion, and one end of this nose has a side end for ejecting nails (a nailing-out side end). ) Is used by being integrally assembled and fixed.

The magazine main body has left and right side plate portions facing each other across the nail storage space, and each nail of the connecting nails stored in the magazine main body is pushed out by a nail sending member (pusher plate), The shafts of the nails are guided from both sides by the left and right side plate parts and are fed into the nose one by one. Then, the nail fed into the nose is violently hit by the driver member that rapidly descends in the nose, and is nailed out from the nose. Here, the entire magazine body, including the left and right side plate portions, is made of an integrally extruded aluminum alloy in order to reduce weight and facilitate manufacturing.

By the way, since the magazine body is integrally assembled and fixed to the nose, when the nail in the nose is hit by the driver member, the vibration generated in the nail driver body is transmitted to the magazine body. . When the magazine body vibrates due to this vibration transmission, the stored nail group vibrates, and the shaft and head of the nail hit the left and right side plates.

[0005]

[Problems to be solved by the device]

 However, the nails housed in the magazine body are made of hard steel, and the material is harder than the magazine body (aluminum alloy). Therefore, on the inner wall surface of the left and right side plates of the magazine body, the part where the vibrating nail hits is gradually worn, and the worn part is dented due to long-term use, and the nail is caught in the recessed part, Will not be able to be sent smoothly.

Further, since the magazine body, the nail, and the nail feed member are made of the same material (the magazine body and the pusher plate are made of aluminum alloy, the nail is made of hard steel), the nail is not slippery and wear-resistant. Lack.

[0007] Furthermore, if the magazine body is made of a metal material (aluminum alloy), the total weight of the nailing machine is heavy, so the workability is poor, and it is desired to reduce the weight in order to reduce the fatigue of the worker's arm, etc. If the nail driver is accidentally dropped, the impact of the drop is large and the nail driver is easily damaged.

Therefore, the present invention has been made to solve the above-described problems, and the magazine body is light in weight, the nails and the magazine body and the like are easily slipped, and the abrasion caused by the vibration of the nailing machine is prevented. The purpose is to provide a magazine of a small number of nailing machines.

[0009]

[Means for Solving the Problems]

 SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a nailing tip of a magazine body having a nail storage space for accommodating nails, which is integrated with a nailing portion of a nailing machine in which a driver member reciprocates. In a magazine of a nailing machine that is automatically assembled to send a nail to an automatic nose part, a wear preventing member for preventing wear of an inner wall is attached to an inner wall surface portion of the magazine body where the head of the nail is abutted. Is provided.

[0010]

[Action]

 A large number of nails (connecting nails) are loaded into the nail storage space of the magazine body. When the nail driver is used in this state, the driver at the nail ejection section reciprocates, and the nails sequentially ejected by the pusher are individually impacted and ejected. This impact causes the nailing machine to vibrate, and this vibration is transmitted to the magazine body. However, since the upper part of the inner wall surface of the magazine body (the part facing the head of the nail) is equipped with a hard metal wear-preventing material, the upper part of the inner wall surface of the magazine body does not wear.

Further, if the magazine main body is made of resin, the total weight is light, and the wear preventing member is used only in a portion where vibration is large, and the other portions are made of resin. Therefore, the part of the nail that comes into contact with the magazine body during the delivery process is mostly made of resin, so the nail slides well.

As shown in FIG. 1, a nailing machine N includes a nailing machine main body 1 for striking a nail with a rod-shaped driver provided in a striking piston cylinder mechanism driven by compressed air, and a large number of nails (connecting It is configured by a magazine main body 21 in which nails are stored.

The nailing machine body 1 includes a body 2 accommodating the striking piston cylinder mechanism and a driver, a nose 3 for striking the nail by the striking of the driver, and a trigger for driving the nail. It is composed of a trigger 4 and the like. Reference numeral 5 is a contact arm, and when the contact arm 5 is pressed against the material to be driven (not shown), the flow path of compressed air is switched, and the trigger 4 is pulled to start hitting the nail. .

As shown in FIGS. 1 to 4, the magazine body 21 has a long magazine case 22 and a magazine cover 23 that are arranged in parallel and opposite to each other, and these cases, covers 22 and 23 are provided. A storage space 24 for storing the connecting nail 40a is formed therebetween. Here, the connecting nails 40a are configured by connecting the individual nails 40 at predetermined intervals by a connecting member made of plastic or the like. The case 22 and the cover 23 are formed by injection molding a resin, and the upper and lower sides of the case 22 and the cover 23 are fixed by screws (not shown). At the center of the inner wall surfaces of the magazine case 22 and the magazine cover 23, ridges 22a and 23b are provided to prevent the tip side of the nail 40 from colliding with the case 22 and the cover 23.

Further, in the magazine body 21, the rear end portion of the nail 40 at the rearmost end of the connecting nail 40 a is abutted and engaged, and the entire connecting nail 40 is provided on one side portion of the nose 3. A metal pusher plate 25 that pushes out in the direction of the mouth (not shown) is slidably arranged. The push-out mechanism of the pusher plate 25 is configured such that a freely rotatable mainspring drum 27 is mounted on a mainspring shaft 26, and a mainspring 28 is wound around the outer periphery of the mainspring drum 27. The left end of the main spring 28 is fixed near the tip of the magazine body 21, and the pusher plate 25 is constantly elastically urged in the nose 3 direction to press the connecting nail 40a toward the nose 3.
