電動工具
Document Type and Number:
Japanese Patent JP7049145
Kind Code:
B2
Abstract:
The utility model provides an electric tool. In a cutting machine that performs cutting processing by rotating a circular cutter attached to a main shaft, a spring force for returning a lock member for locking the rotation of the main shaft to an unlocked position is set to be strong in order to resist the magnetic force of a brushless motor, and in this case, the operability of the lock member tothe locked position side is reduced. The utility model aims to improve the operability of a locking component under the condition. According to the electric tool, fingers (F2, F3, F4 or F5) except athumb (F1) for moving a locking part (51) are hooked on an operation auxiliary part (55), so that the locking part (51) is pressed in the locking direction. The reaction force is received by the operation auxiliary part (55), so that a large pressing operation force can be applied to the locking part (51) more easily.
