Title:
WORK TOOL
Document Type and Number:
WIPO Patent Application WO/2013/058249
Kind Code:
A1
Abstract:
[Problem] To provide a technology capable of holding a tip tool in a work tool by using a simple configuration. [Solution] An electric vibrating tool (100) is configured so as to have an outer flange (130) capable of being attached to and removed from a clamp head (123) formed on a clamp shaft (122). The clamp shaft (122) is configured so as to be movable in the direction of the long axis thereof, according to whether a cam lever (150) is positioned in a clamp position or a release position. When the cam lever (150) is in the release position, the outer flange (130) is positioned on and affixed to the clamp shaft (122) by engaging with the clamp head (123) by moving linearly in a direction that intersects the long-axis direction of the clamp shaft (122). When the cam lever (150) is in the clamp position, the biasing force of a coil spring (138) causes clamping force to be generated between the outer flange (130) and a spindle (120). As a result, a blade (200) is held on the clamp shaft (122) by the clamping force.
