Document Type and Number:
WIPO Patent Application WO/2013/058248
Kind Code:
A1
Abstract:
[Problem] To provide a technology for suppressing the increase in size of a work tool for powering a sandwiched and held tip tool. [Solution] An electric vibrating tool (100) is configured in a manner such that the biasing force of an O-ring (132) or a coil spring (134) that are positioned on the outside of a spindle (120) causes a clamp shaft (123) positioned on the inside of the spindle (120) to be held. In addition, a thrust pin (140) which moves by the revolution of a cam lever (150) causes the removal of the biasing force of the O-ring (132) or the coil spring (134) acting on the clamp shaft (123). As a result, it is possible to remove the clamp shaft (123). Therefore, it is possible to exchange a blade (200) without using a special tool.
