The utility model provides an extracting tool for dismantle the circuit skeleton of detector probe, extracting tool includes and consecutive sleeve, supporting seat and pull rod still includes first and second connecting rods, the sleeve is equipped with on the sleeve along the first and second axial opening wire casings in can stretching into the mounting hole of circuit skeleton, be equipped with first and second connecting holes on the supporting seat, first connecting rod passes first connecting hole, first opening wire casing, and the second connecting rod passes second connecting hole, second opening wire casing, and first and second connecting rods are connected with two fixed orificess of circuit skeleton respectively. The utility model discloses extracting tool technical field canbe used, the axial guide effect is played in the mounting hole through stretching into the sleeve to with two fixed orifices fixed connection on two connecting rods and the circuit skeleton, drive two connecting rods through the pull rod and steadily pull out the circuit skeleton along axial displacement, that this extracting tool has realized is convenient, swift, safe and reliable's dismantlement circuit skeleton, has overcome the dismantlement process led to the fact the damage to inner structure potential safety hazard.
