Abstract

In order to avoid a time consuming procedure of changing a driving source when attaching and detaching an attachment, the driving source is supplied from a battery pack (21) to a dust collecting device (40) in such a way that: a male terminal (57) is projected on the dust collecting device (40); a plug (28), into which the male terminal (57) can be inserted, and a female terminal (27), which is positioned inside the plug (28) and can be electrically connected to the male terminal (57), are provided on a hammer drill (1); and the male terminal (57) and the female terminal (27) are electrically connected with each other when the dust collecting device (40) is attached to the hammer drill (1).

Description

technical field [0001] The present invention relates to a system for supplying a drive source to an accessory in an accessory-attached electric tool in which an accessory such as a dust collector is attached to an electric tool such as an electric drill or an electric hammer drill. Background technique [0002] Power tools such as electric drills and hammer drills are equipped with accessories such as dust collectors that collect and recover dust generated from the workpiece during drilling, etc., and lighting units that illuminate the tip tool. When using such an accessory, it is necessary to supply a drive source to the accessory. Then, for example, Patent Document 1 discloses a system in which, in a system for attaching a dust collector as an accessory to an electric tool equipped with a battery pack as a power source, the dust collector is provided with an interposed part, and via The interposed part mounts the battery pack to the electric tool to obtain the driving sou...
