Abstract
The hand-held electric tool with flexible connector includes handle, casing connected to the handle, working part in the bottom of the casing and core part and features its flexible connector set between the handle and the casing and may be detached. The flexible connector may be of damping elastomer, damping column or damping frame in fense shape. Owing to the flexible connection between the vibration source and the handle, the vibration the working electric tool produces is attenuated before transmitted to hand of the operator, and this improves the working condition and raises the work efficiency.
