摘要
A bit holder for a ploughing bit of a coal or extraction plough includes an insert pocket open on the top side for receiving a bit shank formed on the ploughing bit. The pocket is bounded by two lateral supporting walls, a front and a rear supporting wall, whereby the rear supporting wall has an elevated section projecting over the adjoining, lateral supporting walls. The rear supporting wall forming a bit support for the ploughing bit slopes down to its outer regions. In order to allow a good support for an inserted bit and easy and fast installation of the bit the front face of the rear supporting wall is fitted on the outer regions with guiding surfaces sloping down inwards to the insert pocket as an installation aid for the ploughing bit.
