本案は電気ハンマー等の先端工具の駆動による本体への
衝撃反力及び打撃子の空打ちによる衝撃力を緩和する装
置に関する。[Detailed Description of the Invention] The present invention relates to a device for alleviating the impact reaction force on the main body due to the driving of a tip tool such as an electric hammer and the impact force due to blank firing of the striking element.
従来この種の工具においては、先端工具の戻りの衝撃を
レバーやフロントカバで直接受けるので本体に伝わる反
動が大きいためフロントカバをシリンダケースに固着す
る取付ネジが緩み、本体が破損し、又空転時の空打ち動
作における打撃子の打撃力により同様破損するという欠
点があった。Conventionally, with this type of tool, the impact of the return of the tip tool is directly received by the lever or the front cover, so the reaction force transmitted to the main body is large, which causes the mounting screws that secure the front cover to the cylinder case to loosen, resulting in damage to the main body and idling. There was a drawback that the striking force of the striking element during the dry striking operation caused similar damage.
それを最小限におさえる為、取付ネジの酸ネジ部に高価
なさりサートネジを使用していた。In order to keep this to a minimum, expensive counterseat screws were used for the threaded parts of the mounting screws.
本案の目的は前述の如き従来技術の欠点を除き、この種
の衝撃工具の衝撃反力を緩和し併せて安価な構造を提供
することである。The purpose of the present invention is to eliminate the drawbacks of the prior art as described above, reduce the impact reaction force of this type of impact tool, and provide an inexpensive structure.
即ち、本案は、先端工具の往復動に伴う本体への衝撃反
力を打撃時はレバーの鋼棒で受け、戻りの衝撃は鋼材を
介して弾性体によって形成されたダンパによって受け、
本体への衝撃反力の影響を軽減しようとするものである
。That is, in the present invention, the impact reaction force on the main body due to the reciprocating movement of the tip tool is received by the steel rod of the lever at the time of impact, and the return impact is received by a damper formed of an elastic body via the steel material.
This is intended to reduce the influence of impact reaction force on the main body.
以下図示実施例により本案を説明する。The present invention will be explained below with reference to illustrated embodiments.

１２はレバーで、フロントカバー１１の先端近くに配設
され先端工具１３の脱落を防止する。Reference numeral 12 denotes a lever, which is disposed near the tip of the front cover 11 and prevents the tip tool 13 from falling off.
１４は取付ネジでフロントカバをシリンダケースγに取
りつげると同時にシャンクスリーブ１０を介してダンパ
９を圧装して保持している。Reference numeral 14 attaches the front cover to the cylinder case γ using mounting screws, and at the same time, the damper 9 is press-fitted and held via the shank sleeve 10.
次に上記構成より成る本案の作用を説明する。Next, the operation of the present invention having the above configuration will be explained.
第１図において、フロントカバ１１内を先端工具１３が

、レバー１２でその衝撃力を受け、戻りの衝撃はシャン
クスリーブ１０を介してダンパ９で受けるよう構成して
いるので本体への衝撃力はダンパ９により吸収軽減して
伝わり緩和されるものである。In FIG. 1, the tip tool 13 reciprocates inside the front cover 11. The impact when the tip tool 13 pops out is received by the lever 12, and the returning impact is transmitted via the shank sleeve 10 to the damper 9. Since the impact force on the main body is absorbed and reduced by the damper 9, it is transmitted and alleviated.
又ダンパ９は圧縮されて装着されているので、フロント
カバ１Ｆは前方に常時附勢され取付ネジ１４が緩むのを
防止している。Furthermore, since the damper 9 is mounted under compression, the front cover 1F is always urged forward to prevent the mounting screws 14 from loosening.
本考案によれば、先端工具の戻りの衝撃をシャンクスリ
ーブ１０を介して緩衝用ゴムのダンパ９で受け、又空転
時における打撃子の空打ち動作による打撃力を受けるこ
とにより本体への衝撃が緩和される。According to the present invention, the impact of the return of the tip tool is received by the damper 9 made of cushioning rubber via the shank sleeve 10, and the impact on the main body is also received by the impact force due to the dry striking action of the striking element during idle rotation. eased.
その結果フロントカバ１トシリンダケース７止メネジの
緩み防止である高価なヘリサートネジが削除できる。As a result, the expensive helisert screws used to prevent the front cover 1 and cylinder case 7 set screws from loosening can be eliminated.
また先端工具の衝撃をレバー１２とシャンクスリーブ１
