| 摘要 |
The invention relates to a bit holder for an earth working machine, in particular a road milling machine, having a support member onto which an insertion projection is indirectly or directly attached on an insertion projection side, the support member comprising two first and/or two second stripping surfaces that are at an angle to one another, and the support member having a working side that comprises a bit receptacle. In order to achieve a stable and long-lived configuration for such a bit holder, provision is made according to the present invention that the first and/or second stripping surfaces diverge from the insertion projection side toward the working side. |

1. A tool system for an earth working machine, comprising:
a base part including an insertion receptacle, two first support surfaces at a non-parallel angle to one another, and two second support surfaces at a non-parallel angle to one another and to the first support surfaces; and a tool apparatus including:
an insertion projection received in the insertion receptacle of the base part; anda support member having an insertion projection side and a working side, the insertion projection extending from the insertion projection side, the working side facing away from the insertion projection, the support member including:
two first bearing surfaces at a first angle to one another, the two first bearing surfaces diverging from the insertion projection side toward the working side, each of the first bearing surfaces engaging a respective one of the first support surfaces; andtwo second bearing surfaces at a second angle to one another, the two second bearing surfaces diverging from the insertion projection side toward the working side, each of the second bearing surfaces engaging a respective one of the second support surfaces. |
