The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is: the adjustable chain wrench comprises a first handle used for rotating a hexagon nut in a horizontal plane, a second handle fixed on the first handle and used for rotating the hexagon nut in a vertical plane, a Y-shaped nut clamping piece fixed at the top end of the first handle and used for fixing the hexagon nut, and chains connected to two sides of the nut clamping piece and used for locking the hexagon nut, wherein one side of the nut clamping piece is provided with a clamping groove used for locking the chains, one end of each chain is fixed at one side of the nut clamping piece, the other end of each chain is arranged in the clamping groove, the first handle and the second handle are formed by sleeving a plurality of steel pipes with successively reduced diameters, the lower steel pipe in each two connected steel pipes can be retracted into the upper steel pipe, a push-pull piece used for lengthening and shortening the first handle and the second handle is fixed at the tail end of the lowest steel pipe, and internal threads are arranged on the inner wall of one, and the outer wall of the other end is provided with an external thread, and the connected steel pipes are in threaded connection through the mutual matching of the internal thread and the external thread.
Further, the nut clamping piece comprises two clamping plates and a fixed rod, and the angle between the two clamping plates is 120 degrees.
Furthermore, the fixing mode of the nut clamping piece and the first handle is welding, and the connecting mode of the first handle and the second handle is welding.
The utility model relates to a chain spanner with adjustable multidirectional rotation's beneficial effect is: the clamping plates at the top of the nut clamping piece can be used for clamping a hexagonal nut, the angle between the two clamping plates is 120 degrees and is consistent with the inner angle of the hexagonal nut, so that the clamping is more tight, nuts with different specifications can be matched with a chain through adjusting the length of the chain, the clamping groove can be used for locking the chain and fixing the length of the chain, the first handle and the second handle can be contracted and elongated through a steel pipe, when the nut is positioned on a plane with a larger space, the hexagonal nut is rotated in a horizontal plane where the hexagonal nut is positioned through the first handle, when the nut is positioned on a plane with a smaller space, the first handle is contracted to be shortest, and when the nut is positioned on a plane which the hexagonal nut is positioned through the second handle, the hexagonal nut is rotated in a plane which the horizontal plane where the hexagonal nut is positioned is vertical, although the nut needs to be screwed by larger force, the hexagonal nut can be smoothly operated even if the, the first handle or the second handle can be fixed by the mutual matching of the internal thread and the external thread of the connected steel pipes, so that the first handle or the second handle cannot retract, and the push-pull piece of the steel pipe at the tail end can facilitate the extension and the contraction of the first handle or the second handle. The utility model discloses simple structure, the preparation is convenient, and is applicable in various different specifications, installs in the nut of different positions to locking dynamics to the nut is big, is difficult for the slippage.
