本考案は釘打機のノーズ部に内装填された釘を
所定の姿勢に案内保持する釘打機における釘案内
装置に関する。[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a nail guide device in a nailer that guides and holds a nail inserted in the nose of the nailer in a predetermined position.

しくない。(Prior art and its problems) In general, if the nail loaded into the nose of a nail gun is tilted immediately after driving, there is a risk that the nail will not be driven straight or may buckle. When used for interior boards such as, etc., the paper on the surface may be torn or the board may be damaged, resulting in a decrease in the holding power of the interior board, which is undesirable.

As indicated by reference numeral 15 in Publication No. 40-3068, a holding member made of a leaf spring with a bent midway portion is attached to the inner periphery of the nail driving path in the nose section, and the shaft of the nail is moved toward the center of the nail driving path. In many cases, a guide device for guiding and holding is provided. However, in the case of the above-mentioned guide device, each time the nail is driven, the enlarged diameter head of the nail passing through the nail driving path and the driver member impactfully engage with the holding member, so that the bent portion is folded back each time. Therefore, stress concentrates on this bent part and it tends to deteriorate, causing problems in the durability of the holding member.
Repairing and replacing the leaf springs was also troublesome.

ることはない。(Operations and effects of the invention) According to the above structure, the tip of the nail driven below the nose part by the driver is guided by the nail holding piece that extends onto the driving trajectory and guided to the center position of the nose part. Then, the nail holding piece is expanded and the nail is driven out from the nose part. When the nail holding piece is expanded, the collar portion also tilts, but this tilting is allowed by the contraction of the elastic body, so the holding member does not bend.
上述のように、保持部材がドライバから衝撃を
受けて拡開するが、保持部材は質量が小さい金属
薄板で構成されているので、質量が大きい場合に
比べて保持部材の変位量は小さくてすみ、弾性体

位を規制する筒部が形成されている。したがつ
て、弾性体の耐久性は非常に向上する。 As mentioned above, the holding member expands when it receives an impact from the driver, but since the holding member is made of a thin metal plate with a small mass, the amount of displacement of the holding member is small compared to a case where the holding member has a large mass. , the impact absorption burden on the elastic body is small. Furthermore, the cylindrical body is formed with a cylindrical portion that restricts the holding member from being displaced more than necessary when it receives an impact. Therefore, the durability of the elastic body is greatly improved.
また、弾性体はノーズ部の下端面と保持部材の
鍔部との間に介在しているので、保持部材を閉じ
方向に付勢する弾力部材の変位量を少なくするこ
とができる。 Further, since the elastic body is interposed between the lower end surface of the nose portion and the flange portion of the holding member, the amount of displacement of the elastic member that biases the holding member in the closing direction can be reduced.
さらに、筒状体はノーズ部に対し着脱自在であ
るから、保持部材や弾性部材が破損した場合でも
交換が容易にできる。 Furthermore, since the cylindrical body is detachable from the nose portion, even if the holding member or the elastic member is damaged, they can be easily replaced.
以上のように、本考案によれば、釘案内装置に

形成されている。 Further, the cylindrical body 8 is removably provided by screwing onto the nose portion 1, and protrudes below the nose portion 1 to surround the holding member 5. The cylindrical body 8 is formed with a substantially horizontal step portion 8a that supports the collar portion 5a from below and holds it on the lower end surface of the nose portion 1, and below the step portion 8a is formed the above-mentioned nail. A cylindrical portion 8b is formed to restrict outward expansion of the holding piece 5b.
前記構成によれば、ドライバ３によつてノーズ

形はスムーズに行なわれる。 According to the above configuration, the tip of the nail 4 driven below the nose part 1 by the driver 3 is guided to the center position of the nose part 1 by the nail holding piece 5b that has advanced on the driving trajectory, Furthermore, the nail holding piece 5
It is struck from the nose part 1 by expanding b. When the nail holding piece 5b is expanded, the collar portion 5a is also inclined, but this inclination is allowed by the contraction of the elastic body 10, so that the holding member 5 does not bend. Note that the elongated portion caused by the contraction of the elastic body 10 escapes into the recess 10a, so that the deformation due to the contraction occurs smoothly.
