a groove formed in three of the side surfaces for at least partially accommodating the flexible stem therealong, and holder means for securing the flexible stem close to the free end of the flexible stem when the stem is accommodated in the groove. -
7. An adapter in accordance with claim 6, wherein the groove has a first end at the fixed end of the flexible stem and a second end adjacent to a point at which the free end of the flexible stem is located when the stem is accommodated in the groove.
-
8. An adapter in accordance with claim 2 further comprising circuitry for placing the light in parallel with the electric power tool so as to permit the light to be turned on and off independently from the tool when the adapter is connected to the electric power tool and the battery pack.
-
9. An adapter in accordance with claim 2 further comprising circuitry that gangs together the light and the electric power tool so as to synchronize the operation of the light to that of the tool when the adapter is connected to the electric power tool and the battery pack.
-
10. An adapter in accordance with claim 1, wherein the additional device comprises
a motor that has an output shaft and operates by receiving power from the battery pack, a fan fixed on the output shaft of the motor, a dust chamber that is defined within the main body and accommodates the fan, the dust chamber having an intake side and an exhaust side, a suction nozzle connected to the intake side of the dust chamber, and an outlet pipe connected to the exhaust side of the dust chamber. -
11. An adapter in accordance with claim 10, wherein the suction nozzle and the outlet pipe are disposed on opposing sides of the dust chamber, thus interposing the dust chamber therebetween.
-
12. An adapter in accordance with claim 10, wherein the suction nozzle is connected to the dust chamber via a flexible stem.
-
13. An adapter in accordance with claim 10 further including circuitry for placing the motor in parallel with the electric power tool so as to permit the motor to be turned on and off independently from the tool when the adapter is connected to the tool and the battery pack.
-
14. An adapter in accordance with claim 10 further including circuitry that gangs together the motor and the electric power tool so as to synchronize the operation of the motor to that of the tool when the adapter is connected to the tool and the battery pack.
-
15. An adapter in accordance with claim 1, wherein the additional device comprises a hook secured to the main body for hanging the adapter.
-
16. An adapter in accordance with claim 3, wherein the additional device comprises a hook secured to the main body for hanging the adapter.
-
17. An adapter in accordance with claim 10, wherein the additional device comprises a hook secured to the main body for hanging the adapter.
-
18. An adapter in accordance with claim 1, wherein the first coupling portion is complementarily shaped to the second coupling portion, and further wherein the electric power tool includes a second coupling portion at its bottom surface and the battery pack includes a first coupling portion at its top surface, thus allowing attachment of the adapter to the tool and attachment of the battery pack to the adapter.
