1. An injection device for injecting fixing material in a drill hole during rock bolting, said injection device comprising a hose system and a feed unit, wherein the hose system comprises an injection pipe and an injection feed hose connected to the injection pipe such that movement of the injection feed hose results in movement of the injection pipe; the injection device further comprising a guide for guiding the injection pipe and a positioning device for adjusting the position of the guide and the injection pipe relative to the drill hole for supplying fixing material into the drill hole during operation; said positioning device including one driver for moving said guide and thus said injection pipe along a first axis into one position relative to said drill hole, and another driver for moving said guide and thus said injection pipe relative to said first axis into another position relative to the drill hole, for more precisely aligning said guide and thus said injection pipe relative to said drill hole; wherein said one driver moves the guide laterally along said first axis into said one position, and said another driver tilts the guide into said another position by rotating the guide relative to said first axis.
