Reference numeral 27 denotes the above-mentioned locking portion, which is provided at the tip end side of the vertically divided guide portion 10b of the opening/closing portion 5b and constitutes a locking device 26 with the lock receiving portion 3d of the driver guide 3, and is approximately a cylindrical lock. The cylindrical body 28 is the main body, and the cylindrical body 28 is housed in the lock receiving part 3d of the driver guide 3, and a locking pin 30 having a grip part 31 is attached to a spring 32 at both ends of the hole 29.
It is being shot through. In addition, this locking part 27
into the lock receiving part 3d and inserting the locking pin 30 into the pin receiving part 3e.
When engaged and locked, a guide surface 32 that constitutes a part of the guide wall of the guide hole 3a of the driver guide 3 is formed on a part of the outer circumference of the cylinder 28.

Next, the operation and effects of this embodiment configured as described above will be explained.

Now, the magazine 5 of this example consists of a magazine body 6 and a nail guide part 10, and the magazine body 6 is formed of a cylindrical storage body 7, a lid 8, and a bottom lid 9, and the storage body 7 is vertically divided. The storage body 7 is divided into 7a and 7b in the nail guide part 10.
Divisions 10a and 10b are formed along a vertical dividing line, one vertically dividing guide part 10a is formed integrally with one half cylindrical part 7a, and a bottom cover 9 is integrally provided to form a fixing part 5a. , and the other vertically divided guide section 1
0b is formed integrally with the other half cylindrical part 7b,
and the lid body 8 is integrally provided to form the opening/closing part 5b,
Moreover, a guide surface 32, which constitutes a part of the guide wall of the driver guide 3 communicating with the nail guide section 10, is formed at the tip of the vertically divided guide section 10b of the opening/closing section 5b. Therefore, when the locking device 26 provided at the tip side of the opening/closing part 5b is unlocked, the opening/closing part 5b locks into the hinge part 24 as shown in FIGS. 2 and 3.
The magazine body 6 is rotated laterally and downwardly, and the sides and upper part of the magazine body 6 and the sides of the nail guide part 10 are opened. Therefore, since the opening/closing lid 5b integrally includes the vertically divided guide portion 10b, the half-split cylindrical portion 7b, and the lid body 8, the top and one side surface of the storage body 7 and the side surface of the nail guide portion 10 are in contact with each other. released at the same time.
Therefore, it becomes easy to pull out the nail belt B to the nail guide section 10 after loading the nail belt B into the storage main body 7, or to take out the nail belt B when replacing the nail belt B. In addition, since the opening/closing part 5b is opened downward relative to the fixed part 5a, if the opening/closing part 5b is opened with one hand while holding the nail gun 1 with the other hand, the opening/closing part 5b will open the hinge part 24. The nail belt B can be loaded or replaced with one hand because it is suspended by its own weight and kept in a stable open/closed state. Therefore, the operator can load or replace the nail belt B while holding the nailer 1 in his hand, making the nailer 1 easier to handle. Furthermore, with the rotation of the opening/closing lid 5b, the cylindrical body 28, which has a guide surface forming a part of the guide wall of the driver guide 3 at the tip of the opening/closing part 5b, is also rotated integrally with the opening/closing part 5b. The formed opening 3b is opened to fully open the path through which the nail passes, and the feed pawl and check pawl 23, which are the main parts of the nail feeding mechanism, are also exposed. Therefore, for example, failures such as jammed nails due to problems with the nail feed mechanism can be dealt with extremely easily by opening the opening/closing section 5b, as the path through which the nails pass is fully opened, thereby shortening the time it takes to recover the function. It also has many features such as being able to load the nail belt more easily.

In this embodiment, the locking part 27 is formed separately, but the invention is not limited to this. For example, the cylindrical body 28 having the guide surface 32 may be integrally formed at the tip of the vertically divided guide part 10b. It may also be configured to be provided in.

The present invention is a magazine for a nailing machine in which a nail belt formed by connecting a large number of nails in a band shape is wrapped around and stored. is formed by a cylindrical storage body, a lid body, and a bottom lid,
The storage body is vertically divided and formed, and the nail guide part is also divided along the vertical division line of the storage body, and one vertically divided guide part is integrated with the one half-split cylindrical part. and the bottom cover is integrally provided to form a fixing part, and the other vertically divided guide part is integrally formed with the other half cylindrical part, and the lid body is integrally provided to form a fixing part. furthermore, a part of the guide wall of the driver guide communicating with the nail guide part is formed at the tip of the vertically divided guide part of the opening/closing part, and furthermore, the opening side edge of the bottom cover of the fixing part is formed. and the lower edge of the half-cylindrical part of the opening/closing part are connected by a hinge part that can open and close the opening/closing part laterally and downwardly, so that it has the following effects.

Since the opening/closing lid has the vertically divided guide part, the half-split cylindrical part, and the lid body integrally, when the opening/closing lid is opened, the top and one side of the storage body and the side of the nail guide part are simultaneously exposed. It will be released. Further, the opening/closing part is opened downwardly from the lower edge of the half-cylindrical part via a hinge with respect to the fixed part. Therefore, if you hold the nail gun in one hand and open the opening/closing part with the other hand, the opening/closing part will be suspended by its own weight via the hinge, and in order to keep the opening/closing state stable, you can use the other hand to open the opening/closing part. Belts can be loaded or replaced.

Therefore, since the side surface of the nail guide section is opened at the same time as the storage main body, it is possible to pull out the nail belt into the nail guide section after loading the nail belt into the storage main body, or to remove the nail belt when replacing the nail belt. Easier to take out. In addition, the operator can load and replace the nail belt while holding the nail gun in his hand.
The nailing machine becomes easier to handle.

Furthermore, by forming a part of the driver guide wall that communicates with the nail guide part at the tip of the vertically divided guide part of the opening/closing part, it is possible to fully open the path for the nail to pass through, thereby minimizing problems such as nail jams. This is an extremely practical idea as a nail belt magazine for a nail gun because it can be easily solved and the nail belt can be easily loaded.
