Preferred: described ratchet uses roller gear structure；Described ratchet uses double pawl structures that one connects, ratchet is connected with long handle by being arranged on the bearing pin at middle part and is provided with back-moving spring between ratchet and long handle, when one ratchet of any of which coordinates with the ratchet formation on ratchet, another ratchet disengages with the ratchet on ratchet, makes ratchet and pawl be formed and rotates forward engagement or rotate backward engagement.
Preferred: to be provided with stepped installing hole in one end of long handle Yu sleeve connection, the large aperture part of the most stepped installing hole is sleeved on ratchet, the small-bore part of stepped installing hole is sleeved on sleeve, sleeve is provided with block or back-up ring, described block or back-up ring are arranged on long handle away from the side coordinated with ratchet, make long handle form described axial limiting on the axial direction of sleeve with sleeve；Being provided with ratchet installation cavity at long handle near the position coordinated with ratchet, described ratchet is arranged in ratchet installation cavity.
Preferred: described ratchet and sleeve are integrally machined molding.
Preferred: described axle sleeve is made up of elastomeric material.
Preferred: the distance of the other end of long handle to sleeve central axis is preferably 600mm, the distance of the central shaft of short handle to sleeve central axis is preferably 120mm.
This utility model has the advantage that with good effect:
Use this segment die wrench for dismounting, when the bolt dismantled on segment die, sleeve is enclosed within the nut of bolt, first exerts a force in the end of long handle, make bolt looseness, owing to force arm is longer, bigger moment of torsion can be applied, thus, reach labour-saving effect；When after bolt looseness, integral cycle rotating short handle, owing to the distance of short handle distance sleeve central axis is much smaller than the distance of long handle end distance sleeve central axis, so, it is achieved that the fast quick-detach of bolt.Otherwise, when bolt is installed on segment die by needs, first integral cycle rotating short handle, it is achieved the quick precession of bolt, finally, exert a force in the end of long handle, make bolt lock, reached labour-saving effect equally.To sum up, this segment die wrench for dismounting is used, it is achieved that the fast assembling-disassembling of bolt and there is dismounting labour-saving advantage.
