Abstract

PURPOSE: To adapt a single tool body to the whole tool heads by joining a reduction gear installed on a separating tool head to an electric motor of a main body. CONSTITUTION: A tool head 2 contains a reduction gear 20 and a blind hole 21. This reduction gear 20 is symmetrical with a driving gear 14 of a main body 1 to be driven by the driving gear 14. The blind hole 21 is formed to insert the extending end 13 of a safety switch 11. Next, when either of this tool head 2 is joined to the main body 1, the extending end 13 of the safety switch 11 is inserted into the blind hole 21. In this, the driving gear 14 performs machining by driving the tool head 2 when an electric motor 10 is rotated when a circuit is close after mutually connecting the connecting part 110 and the connecting part 111.

る。(Implementation Arrangement) Referring to the drawings, especially FIG. 2, the main body 1 of the multifunctional electric tool according to the present invention includes an electric motor 10, a safety switch 11, and a drive gear 14. An electric motor 10 is attached to the main body 1 and drives a drive gear 14. The safety switch 11 is a press-type switch attached to the main body 1. The switch has an elongated end 13 extending from the body 1 (FIG. 6A), with one end connected to a spring 12 (FIG. 6A).
