The present invention relates to a stick for mountain climbing, and more specifically, to a stick for mountain climbing for easy adjustment of the length according to the geographical features and surroundings during mountain climbing or walking, through the change in height of a pole shaft using relative deviation of oil pressure and air pressure. The present invention provides a normal stick for mountain climbing used as a walking aid tool for a user to lean the body thereto when mountain climbing or walking, the stick comprising: a main pole shaft having an internal pressure through oil filling or gas injection; an opening/closing controller accommodatingly assembled to the upper side on the inside of the main pole shaft, and causing the moving flow of the oil inside the main pole shaft through an elevating action due to outside pressure; a multilevel elongating pole shaft having extension/admission actions through the influence of the moving flow of the oil while accommodated inside the lower side of the main pole shaft; and an oil groove pipe further assembled inside the elongating pole shaft for smooth flow of the oil inside the main pole shaft. |
