Abstract

An improved electric vibrator tool which is equipped with a driving mechanism housed in the handle case thereof and having an eccentric disc which actuates a driving rod to perform reciprocating operations; a clamping element is attached to the end of the driving rod to receive a tool bit which is reciprocally operated, such as, a tatooing needle, a carving knife and the like; at the end of the handle case is removably attached with a power box in which are disposed non-rechargeable or chargeable batteries and a plug for charging purpose is disposed at the end of the case; or an adaptor is attached instead of battery box to the handle case so that the present vibrator tool can be operated by A.C. power source. A switch concealed inside the tool is actuated by way of rotation so as to make the operation of the tool safer.

Claims

1. An improved electric vibrator tool, comprising:

a handle case;

a power box attached to the end of said handle case;

a driving means disposed inside said handle case and having a driving shaft;

a driving rod having a slot disposed at one end thereof with said driving shaft of said driving means disposed through said slot; and

a recess being defined in association with said slot and having a length equal to the diameter of an eccentric disc so that said disc can be fit inside said recess;

an inner sleeve having a horizontally disposed eccentric disc attached at one end thereof and being disposed inside of said handle case with part thereof protruding the front opening of said handle case;

an outer sleeve having one end thereof engaged with the protruding end of said inner sleeve;

a switch means disposed in abutment with said eccentric disc attached at the end of said inner sleeve and being actuated by rotation of said outer sleeve;

said eccentric disc disposed in said recess being connected with said driving shaft of said driving means led through said slot;

said power box having a container for receiving batteries;

a clamping means secured to the end of said driving rod opposed to the end having said slot defined thereon and being led through said inner sleeve and protruding said outer sleeve.

2. An improved electric vibrator tool as claimed in claim 1 wherein said power box is provided with a plug means at the end thereof for charging the rechargeable batteries disposed therein.

3. An improved elctric vibrator tool as claimed in claim 1 wherein said power box is provided with a pair of electrically conductive pieces at the bottom thereof with an adaptor connected thereto so as to permit said vibrator tool to use A.C. power source.
