[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The following embodiments can enable those skilled in the art to more fully understand the present invention, but the present invention is not limited to the scope of the embodiments.

[0022] like Figure 1-Figure 3 As shown, this specific embodiment adopts the following technical solution: it includes two separately arranged support bases 1, and the two support bases 1 have the same structure, which is convenient for stacking and storage.

[0023] The support seat 1 includes a semi-polygonal clamp 11, a base 12 and a hook 13. The two semi-polygonal clamps 11 of the two support seats 1 are spliced ​​to form a regular hexagonal structure. The semi-polygonal clamp 11 includes two axially symmetrical strip columns 111 and an intermediate column 112 connecting the two strip columns 111. The bottom of the strip column 111 is connected to the base 12 through a connecting column 14. The base 12 and the strip column 111 are connected and fixed by two connecting columns 14, and the two connecting columns 14 are respectively arranged on both sides of the bottom of the strip column 111. The bottom of the open pinion is supported by the base 12, and the outer periphery of the open pinion is supported by the two semi-polygonal clamps 11 to form a hexagonal clamp.

[0024] The two ends of the semi-polygonal clamp 11 are respectively integrated with end blocks 15, and the end blocks 15 extend to the outside of the semi-polygonal clamp 11. The hook 13 is fixed on the top of the end block 15, and the bent hook part of the hook 13 is arranged toward the outside of the semi-polygonal clamp 11. The angle between the hook 13 and the plane of the strip column 111 of the semi-polygonal clamp 11 close to the hook 13 is 45-60°. More preferably, in this embodiment, the angle is 60°. The installation direction of the hook 13 is designed to have a suitable angle to ensure that the hook 13 has a force component toward the middle after the lifting force is applied to achieve a self-locking and clamping effect. The hook 13 is bent at a suitable arc to facilitate the disassembly and assembly of the sling during lifting, and can also avoid scratching the sling.

[0025] A protective structure is installed at the bottom of the end block 15, which includes a mounting block 16 and a locking bolt 17. The mounting block 16 is fixed to the bottom of the end block 15. A through-hole is provided on the mounting block 16. The locking bolt 17 passes through the through-holes on the two mounting blocks 16 close to each other on the two support seats 1 and is then tightened and fixed by a nut.

[0026] Working principle: The weight and overall dimensions of open pinions of different specifications are counted, and the size of the tooling is designed to meet the lifting needs of most such parts. The size of the base 12 should be appropriate and not too large to avoid interference with other dimensions of the part or interference with the working frame of the part processing machine, which will cause inconvenience or unsafe use; the open pinion is lifted by combining two separately set support seats 1. The two support seats 1 have the same structure, which is convenient for stacking and storage; when lifting, the base 12 is used to support the bottom of the open pinion, and the two semi-polygonal clamps 11 are combined to form a polygonal clamp to support the outer periphery of the open pinion. The sling and hook 13 can cooperate to lift the tooling as a whole, thereby lifting the open pinion. The wheel is lifted, and the open pinion can be lifted without a lifting hole. It is convenient to lift, quick to disassemble and assemble, simple to make, and suitable for lifting open pinions with a variety of modules and numbers of teeth. When the tool is in use, after the sling is connected to the hook 13, the two support seats 1 move to the bottom of the sling due to gravity, and the two support seats 1 are close to each other, achieving a clamping effect and more stable use. During lifting, the ends of the two support seats 1 that are close to each other are connected by locking bolts 17 through the through holes on the mounting block 16. A secondary protection design is reserved, which has a protective effect and serves as a double insurance. At the same time, it can fix some special parts that are easy to slip, prevent them from slipping and falling during the lifting process, and ensure stable lifting, safety and reliability.
