ABSTRACT:
Devices for holding mining and road maintenance cutter bits, wherein said devices for holding comprise a cutter bit support block, a clevis and a support block locking mechanism whose geometries have been adapted such that the cutter bit support block can be fixedly and rigidly held in a channel in the clevis by the support block locking mechanism, which has a locking bolt. The support block locking mechanism and the clevis have means for interacting and cooperating such that each abuts with, and applies a downward pressure to, a lower body portion of the support block and thereby drives downward facing longitudinal shoulders on the support block into abutment under pressure with upward facing abutment shoulders of two longitudinal walls forming the channel in the clevis.
