８’は、該伸縮ステー８の先端部の外周面に設けられた把持部である。   Reference numeral 8 ′ denotes a gripping portion provided on the outer peripheral surface of the distal end portion of the telescopic stay 8.

上記伸縮ステー８は、上記エアシリンダ６の伸縮ロッド７の伸縮により、上記支柱体基部１に対して伸縮するもので、伸縮ロッド７を最も縮退させると、先端部のみがガイドステー３から上方に突出した状態となり（図１(a)）、また、伸縮ロッド７を最も伸出させると、該伸縮ステー８の先端側の約半分がガイドステー３から上方に突出した状態となる（図１(b)）。   The expansion / contraction stay 8 expands / contracts with respect to the support base 1 by expansion / contraction of the expansion / contraction rod 7 of the air cylinder 6. When the expansion / contraction rod 7 is retracted most, only the distal end is upward from the guide stay 3. When the telescopic rod 7 is extended to the maximum, about half of the distal end side of the telescopic stay 8 projects upward from the guide stay 3 (FIG. 1 (a)). b)).

１１は、上記伸縮ステー８の先端に設けられた取付板１２を有するボールジョイント等の手持工具用自在継手である。   Reference numeral 11 denotes a universal joint for a hand-held tool such as a ball joint having a mounting plate 12 provided at the tip of the telescopic stay 8.

１６は、上記伸縮ステー８の先端部に設けられた二方切替弁で、これはレバー操作により、上記三方弁１４で分岐された上記エアシリンダ６へのエアの供給をコントロールし伸縮ロッド７を伸縮させるものである。   Reference numeral 16 denotes a two-way switching valve provided at the tip of the telescopic stay 8, which controls the supply of air to the air cylinder 6 branched by the three-way valve 14 by lever operation, It is intended to expand and contract.

上記構成からなる本実施例の手持工具の作業用支承装置は、手持工具用自在継手１１にエアチッパー１３を取り付けて、支柱体支持用自在継手４の台座部５を適宜の場所に接地させるとともに、一方の手で伸縮ステー８の把持部８’を把持し、他方の手でエアチッパー１３の把持部１３’を把持することにより、エアチッパー１３の荷重を支承させながら所望のはつり作業を行うことができるものである。   In the working support device for a hand-held tool of the present embodiment having the above-described configuration, an air chipper 13 is attached to the hand-held tool universal joint 11, and the pedestal portion 5 of the support body supporting universal joint 4 is grounded to an appropriate place. By gripping the gripping portion 8 ′ of the telescopic stay 8 with one hand and gripping the gripping portion 13 ′ of the air chipper 13 with the other hand, it is possible to perform a desired lifting operation while supporting the load of the air chipper 13. Is.

その際、把持部８’を把持している上記一方の手で、上記支柱体支持用自在継手４により支持された支柱体１０を所望の方向に傾動させれば、エアチッパー１３を任意の方向に移動することができ、また、把持部８’を把持した一方の手で、該把持部８’を把持したまま上記二方切替弁１６のレバーを操作し、伸縮ロッド７を所望の量だけ伸縮させてエアチッパー１３を上下に移動させることができる。   At that time, if the column body 10 supported by the column body supporting universal joint 4 is tilted in a desired direction with the one hand holding the gripping portion 8 ', the air chipper 13 is moved in an arbitrary direction. It is possible to move, and with one hand gripping the gripping portion 8 ′, the lever of the two-way switching valve 16 is operated while gripping the gripping portion 8 ′, and the telescopic rod 7 is expanded and contracted by a desired amount. Thus, the air chipper 13 can be moved up and down.

また、エアチッパー１３の把持部１３’を把持している他方の手で、エアチッパー１３それ自体の向きを適宜変更でき、またそのスイッチの操作を行うことができる。   Further, the direction of the air chipper 13 itself can be changed as appropriate with the other hand holding the grip portion 13 ′ of the air chipper 13, and the switch can be operated.

この手持工具の作業用支承装置は、上記のとおりエアチッパー１３の移動を一方の手で行え、また、エアチッパー１３自体の向きの変更およびスイッチ操作を他方の手で行えるようにしており、また、エアシリンダ６を軽量合金製とし全体として軽量なものとしているので、扱いやすい。   This hand-held tool working support device can move the air chipper 13 with one hand as described above, and can change the direction of the air chipper 13 itself and switch operation with the other hand. Since the cylinder 6 is made of a lightweight alloy and lightweight as a whole, it is easy to handle.

また、エアシリンダ６の伸縮ロッド７と、伸縮ステー８との間にはダンパーゴム９が取り付けられており、これによりエアチッパー１３の振動等を吸収することができる。   Further, a damper rubber 9 is attached between the telescopic rod 7 of the air cylinder 6 and the telescopic stay 8, so that vibrations of the air chipper 13 and the like can be absorbed.

この手持工具の作業用支承装置はまた、伸縮ステー８の伸縮を、エアチッパー１３と同じくエアを利用して、エアシリンダ６によって行うようになっているから、支柱体１０に自在継手４，１１や三方弁１４等を取り付け、またエアホースを配管するだけで簡単に、しかも低コストで製作できる。   In this hand-held tool working support device, the expansion and contraction stay 8 is expanded and contracted by the air cylinder 6 using the same air as the air chipper 13. It can be manufactured easily and at low cost simply by attaching a three-way valve 14 or the like and piping an air hose.

図２，３に本発明の実施例２に係る手持工具の作業用支承装置を示す。
この手持工具の作業用支承装置は、上記実施例１の手持工具の作業用支承装置とは、保護パイプ１７を取り付けている点を異にするのみであるから、同一の部分に同一の符号を付すこととし、相違点についてのみ説明する。 2 and 3 show a working support device for a hand-held tool according to Embodiment 2 of the present invention.
Since the working support device for a hand-held tool differs from the working support device for a hand-held tool of the first embodiment only in that the protective pipe 17 is attached, the same reference numerals are used for the same parts. Only the differences will be described.

上記保護パイプ１７は塩ビ製の中空筒状のもので、伸縮ステー８、およびガイドステー３すなわち支柱体基部１の上半部に外嵌され、上端を伸縮ステー８の先端部の保護パイプ固定用ピン８”に固定している。   The protective pipe 17 is in the form of a hollow tube made of PVC, and is fitted on the telescopic stay 8 and the guide stay 3, that is, the upper half of the column base 1, and the upper end is used to fix the protective pipe at the distal end of the telescopic stay 8. It is fixed to pin 8 ".

この保護パイプ１７は、伸縮ステー８が支柱体基部１に対して伸縮するときに、伸縮ステー８とともに移動し、これにより該伸縮ステー８のガイドステー３から突出した部分は、常に保護パイプ１７により被覆された状態となり（図２，３）、はつり作業により落下してくるはつりかす等によって傷つけられることがないようになっている。
また、伸縮ロッド７を縮退させた状態（図３(a),(b)）ではガイドステー３も被覆された状態となる。 The protective pipe 17 moves together with the expansion / contraction stay 8 when the expansion / contraction stay 8 expands / contracts with respect to the support base 1, and the portion of the expansion / contraction stay 8 that protrudes from the guide stay 3 is always protected by the protection pipe 17. It is in a covered state (FIGS. 2 and 3) so that it will not be damaged by dropping or dropping, etc. due to the hanging work.
Further, when the telescopic rod 7 is retracted (FIGS. 3A and 3B), the guide stay 3 is also covered.

なお、上記では手持工具としてエアチッパーを取り付けた例について説明したが、電動ピック等、他の手持工具を同様にして取り付けることもできる。   In addition, although the example which attached the air chipper as a handheld tool was demonstrated above, other handheld tools, such as an electric pick, can also be attached similarly.
