Technical Field

[0001] The utility model relates to the technical field of lifting tools, and more specifically, to a claw-type adjustable eccentric lifting tool. Background Art

[0002] In current industrial production and logistics transportation, as an important auxiliary tool, lifting tools are widely used in hoisting, handling and installing various equipment and materials. However, when dealing with workpieces of specific shapes and sizes, especially eccentric workpieces, traditional lifting tools often have problems such as complex installation, inaccurate positioning, and uneven clamping force, which not only affect work efficiency but may also cause damage to the workpieces and the lifting tools themselves.

[0003] When hoisting eccentric workpieces, traditional lifting tools usually need to pre-set screw holes on the workpieces or use complex connecting devices, which not only increases the installation steps but may also lead to inaccurate installation positions. And the clamping mechanisms of traditional lifting tools often cannot be flexibly adjusted according to the shape and size of the workpieces, resulting in uneven distribution of the clamping force and easy deformation or damage of the workpieces.
