Description of the Related Art Generally, a nail driving machine includes a magazine containing a connecting nail, a nose portion for slidably housing a driving driver, and a feed mechanism for feeding the connecting nail in the magazine to the nose along a feed path. After the leading nail of the connecting nail in the magazine is supplied to the nose portion by the feed mechanism, the driver for driving is driven to drive the leading nail in the nose portion toward the material to be driven. As shown in FIG. 5, a feed piston / cylinder device 21 is disposed along the feed passage 20, and the feed claw 2 rotatably attached to the tip of the rod 22 together with the feed piston 21a.
3 is reciprocated so that the connecting nail 24 in the feed passage is fed into the nose portion 25.
【０００３】ところで、釘打機は全体がコンパクトの方
が使い回しが楽であり、狭い場所での釘打ち込み作業も
可能となるため、より一層の小型化が求められている。[0003] By the way, the nail driving machine is more compact when used as a whole, and can be used in a narrow place. Therefore, further miniaturization is required.

作業を連続的に行なうことは難しくなる。However, the feed passage 20 is formed in the diameter direction of the magazine 26, and the feed piston / cylinder device 21 is arranged in parallel with the feed passage 20. Since the dimensions of the feed mechanism portion composed of the feed nail and the feed nail were determined by the nail connection pitch of the connection nail, the magazine 26
It was not possible to reduce the distance between the nose portion 25 and the nose portion 25. Further, when the magazine 25 is made small, the connecting nails are inevitably shortened, so that it is difficult to continuously drive a large number of nails.

First, compressed air is supplied from the air supply hole 12 at the end of the feed cylinder 7a. Thus, as shown in FIG. 3, the feed piston 7b resists the spring force of the spring 11 and the second nail 5b
Retreat to. Thereafter, when the compressed air is exhausted, the feed piston 7b moves forward by the spring force of the spring 9. Along with this, the feed claw 8 also advances in parallel along the feed path 6 by the spring force of the spring 11, engages with the second nail 5b from the head, and feeds out the connecting nail 5 by one nail. The leading nail 5a is supplied to the nose part 4.

る。As described above, the feed piston / cylinder device 7 is arranged tangentially to the magazine 3 and the staple feed passage 6 is arranged in parallel with the feed piston / cylinder device 7. As compared with the nailing machine shown, the distance L between the nose part 4 and the magazine 3 is shortened, making the nailing machine more compact than the conventional nailing machine.
A nailing machine that is easy to handle and has good workability can be obtained.

Is preferably arranged parallel to the staple feed passage 6, but may not necessarily be parallel when it is difficult to connect the members. In this case, although not shown, for example, a part is rotatably interposed between the rod 10 of the feed piston 7b and the feed claw 8 within a certain range so that the feed piston 7b approaches or separates from the feed passage 6 to displace. What is necessary is just to comprise so that the feed nail | claw 8 may reciprocate in the feed path 6 by absorbing by the said components.
