Problems solved by technology

[0005] However, in the system of the above-mentioned Patent Document 1, for the case of using accessories and the case of using the electric tool alone, it is necessary to remove the battery pack and assemble it alternately to the electric tool and the accessories, which is time-consuming.
In addition, in the system of Patent Document 2, an external power supply needs to be carried separately, which is not only cumbersome, but also needs to be installed when the power tool is used alone, so the convenience of use is poor.

Embodiment Construction

[0027] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0028] [Method 1]

[0029] figure 1 Shown is an electric hammer drill that is an electric tool equipped with a dust collector as an accessory, figure 2 The hammer drill is shown in one piece. First, the electric hammer drill 1 is assembled on the front side of the housing 2 formed by assembling a pair of left and right housings (the figure 1 , figure 2 the right side as the front. ) in the center, the motor 3 is accommodated in an oblique posture in which the output shaft 4 is inclined backward, and the intermediate shaft 6, which transmits torque through the bevel gears 5 and 5 above it, is equipped with the first gear 7, the clutch 8, and the hub sleeve in order from the front. 9. Above the intermediate shaft 6, a tool holder 11 is axially supported parallel to the intermediate shaft 6. A bit 10 can be inserted into the front end of the tool holder 11, and the...

Abstract

PROBLEM To eliminate trouble of switching of a driving source when an attachment device is mounted or removed. SOLUTION TO THE PROBLEM A male terminal (57) is formed on a dust collecting device (40) so as to protrude therefrom, while a plug-in port (28) into which the male terminal (57) can be inserted, and a female terminal (27) that is located inside the plug-in port (28) and can be electrically connected to the male terminal (57), are provided in a hammer drill (1). When the dust collecting device (40) is joined to the hammer drill (1) and the male terminal (57) is electrically connected to the female terminal (27), a driving source is supplied from a battery pack (21) to the dust collecting device (40).

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...
