PROBLEM TO BE SOLVED: To solve the problems that safety is remarkably impaired and the risk of injury is considered since a coconut itself is unstable although the hole of the coconut is conventionally made so as to shave the coconut with a hatchet and the screening of shavings is needed when drinking coconut juice due to the occurrence of the shavings when making the hole with a drill and the like.SOLUTION: For solving problems, a jack is disposed on a plate attached with a cylindrical cutting edge (cutter) at the upper end of a support shaft so as to face downward and a plate attached to the lower end of the support shaft, a table for putting a coconut is disposed on the upper part of a jack telescopic portion (jack arm), the cylindrical cutting edge (cutter) is cut into the coconut by acting the jack and extending the jack telescopic portion (jack arm) and then a hole can be opened.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】従来、ヤシの実に穴を空ける場合、大ナタなどでヤシの実を削るように穴をあけていたが、ヤシの実自身が不安定ということもあって、安全性に著しく欠け、怪我をする危険性があった。また、ドリルなどで穴をあけた場合には、削りカスが出るため、ヤシの実のジュースを飲む際には、削りカスをこして飲まなければならなかった。【解決手段】上記の問題を解決するにあたり、支持シャフト上端部に円筒状の刃先(カッター)が下向きになるように取り付けられた板と、支持シャフト下端部に取り付けられた板にジャッキを設置し、ジャッキ伸縮部(ジャッキアーム)の上部にヤシの実をのせる台を設置し、ジャッキを作用させることで、ジャッキ伸縮部(ジャッキアーム)が伸びて、円筒状の刃(カッター)がヤシの実に食い込み穴をあけることができる。【選択図】図1
