For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0028] As Figure 3 shown, the adjustable tool based on the hull line type of the preferred embodiment of the present application comprises a first adjusting assembly 1, the first adjusting assembly 1 comprises a middle support assembly 11 and two side support assemblies 12, the two side support assemblies 12 are respectively located on both sides of the middle support assembly 11 along a first direction X, each side support assembly 12 comprises a side support block 121, a first movable piece 122 and at least two lifting assemblies 123, the first movable piece 122 extends along the first direction X, one end of the first movable piece 122 is rotationally connected to the middle support assembly 11, the other end of the first movable piece 122 slides through the bottom of the side support block 121, the bottom of the side support block 121 is provided with a first fastener 1211 for locking or unlocking the first movable piece 122, the lifting assemblies 123 are arranged in a spaced manner along a second direction Y, the lifting assemblies 123 are telescopic and the top ends of the lifting assemblies 123 are rotationally connected to the side support block 121, the first direction X is perpendicular to the second direction Y.

[0029] The adjustable tool based on the hull line type in the above embodiment can support the transverse flat part at the longitudinal keel of the ship bottom by arranging the middle support assembly 11, the second direction Y is kept parallel to the longitudinal direction of the ship body during use, the side support block 121 can support the side of the ship bottom as a pier, since the side support block 121 is rotationally connected to the lifting assemblies 123 arranged along the second direction Y at the bottom of the side support block 121, and the side support block 121 and the middle support assembly 11 are connected through the first movable piece 122 arranged along the first direction X, therefore, after unlocking the first fastener 1211, the side support block 121 will rotate together with the first movable piece 122 by adjusting the telescopic lifting assemblies 123, the side support block 121 also slides along the first movable piece 122 when rotating, the angle change of the "V" shape formed by the two side support blocks 121 and the middle support assembly 11 can be observed from the second direction Y, the side support block 121 can be adjusted to an appropriate angle to adapt to the hull line type, and the first fastener 1211 is locked after adjustment.

In addition, since the inner diameter of the connecting cylinder 1231 is larger than the outer diameter of the first rotating column 1213, the two connecting cylinders 1231 for penetrating through the same first rotating column 1213 can adjust different height differences so that the first rotating column 1213 can adjust the angle with the horizontal plane within a certain range, and thus the side support block 121 can also adapt to the linear change of the ship body along its longitudinal direction. Since the longitudinal length of the ship body is much larger than the transverse width, the linear change of the ship body in the longitudinal direction is much gentler than that in the transverse direction, and thus the tooling can adjust and adapt to the longitudinal linear change of most ship bodies, and thus the tooling can adapt to the linear change of the ship body in multiple dimensions.

By installing the first adjusting assembly 1 on the second adjusting assembly 2, adjusting the telescopic adjusting piece 21 to be shortened can make the wedge-shaped plates 22 approach each other and the stacking thickness increase, and the height of the first adjusting assembly 1 rises, adjusting the telescopic adjusting piece 21 to be lengthened can make the wedge-shaped plates 22 move away from each other and the stacking thickness decrease, and the height of the first adjusting assembly 1 decreases, and in work, the height of the first adjusting assembly 1 is first adjusted by the second adjusting assembly 2 to make the middle supporting assembly 11 abut against the flat part of the hull bottom, and then the angle adjustment of the side supporting blocks 121 is completed.
