Embodiment Construction

[0019] FIG. 1 shows a perspective view of an electric power tool with a suction system. The suction system comprises an additional handle 10 , a suction device 11 for receiving air contaminated with drill cuttings and a suction channel 29 for suctioning the air out. The additional handle 10 has a grip part 30 and a locking ring 25 . With the aid of locking ring 25 , attachment handle 10 is mounted on electric power tool 12 , which is designed as a drill in FIG. 1 . In this case, the locking ring 25 is placed on the housing of the power tool 12 or on the tool holder 27 and is secured by a suitable locking device.

[0020] The exact structure of the stop device can be seen from FIGS. 2 and 3 . In this case, identical elements are each provided with the same reference numerals.

[0021] FIG. 2 here shows a detail view of a locking ring 25 . A total of six grooves 13 , 14 , 15 , 16 , 17 , 18 are formed on the inner peripheral surface 24 of the locking ring, wherein the grooves...

Abstract

The invention relates to a fastening device for connecting an additional handle (10), for example of a suction device (11), to an electric machine tool (12), wherein the additional handle (10) ) has first stop mechanisms (13, 14, 15, 16) at its connection points. These first stop mechanisms can be connected to corresponding second stop mechanisms configured in a corresponding number and arranged on the electric power tool. The number of the first stop mechanisms (13, 14, 15, 16, 17, 18) is greater than that of the second stop mechanisms (19, 20, 21, 22). , 23) at least one more. Furthermore, the invention relates to an electric power tool having an additional handle.

Description

technical field [0001] The invention relates to a fixing device and an electric power tool. Background technique [0002] Fastening devices for connecting an additional handle, in particular an additional handle of a suction device, to an electric power tool are generally known. According to the prior art, such a fastening device comprises a clamping sleeve or a locking ring formed on the additional handle, wherein the clamping sleeve or locking ring is placed on the drill spindle and the connection can be established by means of a locking device . According to the prior art, these locking devices remain neutral, so that the additional handle can be mounted on the electric power tool in a plurality of arbitrary positions. For example, a fastening device is known in which the additional handle has grooves at its connecting points, which grooves can be connected to corresponding ribs which are configured in a corresponding number and which are provided on the electric power ...
