Title:
BENDABLE MACHINING TOOL
Document Type and Number:
WIPO Patent Application WO/2015/178293
Kind Code:
A1
Abstract:
Provided is a bendable machining tool in which the base end of a guide section (3) that has a long and narrow shape is connected to a handpiece (4). A tip member (2) that is bendable with respect to the guide section (3) is provided to the tip of the guide section (3). A tool (1) is rotatably supported by the tip member (2). The guide section (3) internally comprises: a rod member (24) that advances or retreats in the axial direction and changes the bending angle of the tip member (2); and a tool rotation shaft (23) that transmits the rotation of a tool rotation drive source (60) to the tool. The rod member (24) is made to advance or retreat as a result of the hand of an operator performing rotating operation of a dial member (6) that is rotatably provided to the handpiece (4). A reverse input prevention mechanism (87) is provided to the bendable machining tool in order to prevent rotation of the dial member (6) as a result of force acting on the tip member (2).
