In order to overcome above-mentioned the deficiencies in the prior art part, the utility model provides a kind of bolt and nut dismantling device, assembling-disassembling bolt nut in the environment that can be difficult to get at staff, and one-hand operation and bolt and nut do not come off, simple and safe.
The utility model is achieved by the following technical solution: a kind of bolt and nut dismantling device, and it comprises the body of rod, and one end of the body of rod is fixed with sleeve, and the end of sleeve is manufactured with the hexagonal draw-in groove with bolt and nut adaptation, and there is magnetic head the inside of hexagonal draw-in groove; Knee is also housed on the described body of rod, there is movable end one end of knee, movable end is sleeved on the described body of rod, the other end of knee is connected with cutting ferrule, is manufactured with and the draw-in groove of bolt and nut adaptation on cutting ferrule, has the supporting plate that prevents that bolt and nut from coming off in draw-in groove, described sleeve is between described movable end and cutting ferrule, between sleeve and movable end, spring is housed, between sleeve and cutting ferrule, leaves gap, described movable end, sleeve and being fastened on same axis.
Between described sleeve and the body of rod, be connected with connector, described sleeve is all flexibly connected with described connector with the body of rod.
Described sleeve is flexibly connected with the body of rod.
Described cutting ferrule is cylindrical shape.
One side of described cutting ferrule has the bayonet socket entering for bolt and nut.
Described knee is arc or " U " shape.
Jug on the described body of rod.
Described handle is hinged on the described body of rod.
On the described body of rod, be movably installed with suspension ring.
The beneficial effects of the utility model are: the utility model can stretch to assembling-disassembling bolt nut in the environment that staff is difficult to get at, knee can stride across the junction of bolt and nut flexibly, cutting ferrule and sleeve block respectively two parts of bolt and nut component, because movable end does not rotate with the body of rod, therefore can make bolt and nut component disengaging or fastening by the rotation body of rod, the adsorbable bolt and nut of magnetic head in sleeve, in draw-in groove, there is the supporting plate that prevents that bolt and nut from coming off, the utility model one-hand operation and bolt and nut do not come off, simple in structure, firm, practical.
