Abstract

The invention relates to a special wrench for removing anchor bits, which comprises a handle (1), wherein one end of the handle is connected with a sleeve (2); and the special wrench is characterized in that one end of the sleeve is provided with a clamp hole matched with an anchor bit. The special wrench disclosed by the invention has the beneficial effects that the special wrench is not only simple in structure and convenient to operate, but also realizes the mutual separation of an anchor bit and a bit connecting sleeve, so that through separately replacing the anchor bit, the bit connecting sleeve can be reused, thereby greatly reducing the production cost and the resource consumption.

Description

technical field [0001] The invention relates to a metalworking tool, in particular to a special wrench for dismantling an anchor drill bit. Background technique [0002] At present, mine roadways mostly adopt a huge number of anchor cables and bolts for joint support, and the number of holes for installing anchor cables and bolts is also quite huge. When using a rock bolter to drill holes, the drill bit connected to the drill pipe through the drill bit connecting sleeve is the most vulnerable part. Because there is no special tool for dismounting this anchor bit in the prior art, the anchor bit cannot be directly unloaded from the drill bit connecting sleeve. The drill bit connecting sleeve of the anchor drill bit is replaced together, so a large amount of material waste will be caused, and the production cost will be improved. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the lower rocker bit in the prior art cannot...
