Description

Lifting device and lifting assembly Technical Field The utility model relates to the technical field of hoisting tools, in particular to a hoisting tool and a hoisting assembly. Background In the design process of some shaft parts, the design scheme of structural optimization is usually followed, and the cost optimization solution is often sought on the design of the product itself, but excessive design consideration is not needed in the production and transportation links, so that a plurality of inconveniences are brought to the hoisting and transportation of the product. Lifting devices in the related art mostly adopt a traditional thread tightening structure, a threaded hole suitable for lifting is required to be formed in a proper position on the shaft part, and the production and processing of the threaded hole increase the production cost of products. In addition, the hoisting scheme using the threaded holes is used for locking threads when the lifting appliance is installed, so that the installation efficiency is low, and the production beat is influenced. There is therefore a need for a new lifting tool and lifting assembly. Disclosure of utility model The utility model aims to provide a hoisting tool and a hoisting assembly, wherein the hoisting tool is provided with a plurality of split-type clips, and can be mutually matched to form a containing cavity when in a clamping working condition, a limiting section in the containing cavity is clamped with a workpiece so as to clamp the workpiece, the workpiece is not required to be additionally processed, the manufacturing cost is reduced, and meanwhile, the hoisting failure and the workpiece falling caused by virtual connection can be avoided through a reasonable structural design. The embodiment of the utility model discloses a lifting tool which is used for lifting a workpiece and comprises a plurality of clips; The plurality of clips are provided with circumferential side walls, and the inner surface of at least one circumferential side wall is provided with a limiting section which is arranged in a circumferential extending way; When the workpiece clamping device is in a clamping working condition, the clamping buckles are sequentially connected, so that the circumferential side walls are surrounded to form a containing cavity for containing the workpiece, the containing cavity is at least provided with one side opening, and the limiting section is located in the containing cavity and used for clamping the workpiece.
