MALFUNCTION COUNTERMEASURE SWITCH MECHANISM OF WET TYPE ELECTRIC DRILL, AND WET TYPE ELECTRIC DRILL
To provide a malfunction countermeasure switch mechanism of a wet type electric drill free from the risk of the malfunction in a switch of a vacuum device or a water feed device and capable of preventing the stain or wet of the circumference with cooling sewage water or cooling water, and a wet type electric drill comprising the same.SOLUTION: In a malfunction countermeasure switch mechanism 1 of a wet type electric drill 100 preventing the malfunction of a switch 5 of a vacuum device sucking cooling sewage water or water feed device feeding cooling water in the wet type electric drill 100, a drain mechanism 13 of cooling sewage water communicated with the vacuum device comprises a telescopic tube 14 telescopic in accordance with a drilling depth after drilling by the wet type electric drill 100, and comprises a shaft 20 in which the telescopic motion of the telescopic tube 14 and the retraction operation of the shaft 20 are linked. A switch 4 is fitted in such a manner that the operation line of an ON-OFF operation is superimposed with the projection orbit of the shaft 20, and the switch 4 cannot be ON or OFF or is hard to be operated upon the projection of the shaft 20.SELECTED DRAWING: Figure 8
【課題】バキューム装置や給水装置のスイッチを誤動作するおそれがなく、冷却汚水や冷却水で周囲が汚れたり濡れたりすることを防止することができる湿式電動ドリルの誤動作対策スイッチ機構及びそれを備えた湿式電動ドリルを提供する。【解決手段】湿式電動ドリル１００の冷却汚水を吸引するバキューム装置又は冷却水を供給する給水装置のスイッチ５の誤動作を防止する湿式電動ドリル１００の誤動作対策スイッチ機構１において、バキューム装置と連通する冷却汚水の排水機構１３は、湿式電動ドリル１００で削孔した削孔深さに応じて伸縮する伸縮チューブ１４を備えており、伸縮チューブ１４の伸縮とシャフト２０の突没動作が連動するシャフト２を設け、スイッチ４を、ＯＮ・ＯＦＦ動作の動作線がシャフト２０の突出軌道と重なるように取り付け、シャフト２０の突出時に、スイッチ４をＯＮ又はＯＦＦできない、又は操作し難いように構成する。【選択図】図８
