The lifting ring assembly 1 is rotatably connected to the first rotating shaft 4. In order to facilitate clamping of the cylindrical target, the two ends of the first rotating shaft 4 are symmetrically provided with the jaw assembly 2, and the first rotating shaft 4 and the second rotating shaft 5 are arranged at intervals in the vertical direction.

[0023] Specifically, in this embodiment, there are 2 jaw assemblies 2. For the convenience of designing the jaw assembly 2, refer to Figure 1 , Figure 2, the jaw assembly 2 includes a first connecting rod 21, a second connecting rod 22, a first jaw 23, and a second jaw 24. One end of each of the first connecting rod 21 and the second connecting rod 22 is rotatably connected to the first rotating shaft 4. The other ends of the first connecting rod 21 and the second connecting rod 22 are arranged opposite to each other. The other end of the first connecting rod 21 is hinged with the first jaw 23, and the other end of the second connecting rod 22 is hinged with the second jaw 24. The second rotating shaft 5 is hinged to the middle parts of the first jaw 23 and the second jaw 24. That is, the first connecting rod 21, the second connecting rod 22, the first jaw 23, and the second jaw 24 form a rhombic four-bar mechanism. For the convenience of clamping the cylindrical target, and at the same time, to avoid scratching the outer wall of the cylindrical target during the clamping process, a first clamping portion 231 is provided at the other end of the first jaw 23, and a second clamping portion 241 is provided at the other end of the second jaw 24. The first clamping portion 231 and the second clamping portion 241 are arranged opposite to each other. A flexible gasket assembly 3 is provided on the first clamping portion 231, the second rotating shaft 5, and the second clamping portion 241. As Figure 1 shown, the flexible gasket assemblies 3 at the three places of the first clamping portion 231, the second rotating shaft 5, and the second clamping portion 241 surround and form a clamping area for clamping the circular target.

[0024] Further, for the convenience of designing the flexible gasket assembly 3 and simplifying the structure, refer to Figure 1 , Figure 2 , Figure 3 , in this embodiment, the flexible gasket assembly 3 includes an arc-shaped connecting plate 31 and a rubber pad 32. For the convenience of fixing the arc-shaped connecting plate 31, ear plates 311 are provided at intervals along the axial direction on the arc-shaped outer wall of the arc-shaped connecting plate 31, and a rubber pad 32 is provided on the arc-shaped inner wall of the arc-shaped connecting plate 31. Specifically, through holes are opened on the ear plates 311. In this embodiment, one arc-shaped connecting plate 31 is simultaneously connected to two first jaws 23 or two second jaws 24, and the arc-shaped connecting plate 31 can be fixed to the above-mentioned jaws by screwing screws through the ear plates 311. In addition, the arc-shaped connecting plate 31 can be fixed to the second rotating shaft 5 through the ear plates 311.

[0025] Furthermore, since the arc-shaped connecting plate 31 provides support when handling the cylindrical target, it needs to have a certain support strength. The arc-shaped connecting plate 31 is made of a metal material. In this embodiment, for the convenience of fixedly connecting the arc-shaped connecting plate 31 and the rubber pad 32, counterbores are evenly distributed on the inner wall of the rubber pad 32, and threaded holes corresponding to the counterbores are provided on the arc-shaped inner wall of the arc-shaped connecting plate 31. The arc-shaped connecting plate 31 and the rubber pad 32 are fixedly connected by screws. In some embodiments, to avoid the arc-shaped connecting plate 31 colliding with the cylindrical target and causing scratches when clamping the circular target, the length of the arc-shaped connecting plate 31 extending along the axial direction is less than or equal to the length of the rubber pad 32.

[0026] Specifically, to facilitate the hinged connection between the first connecting rod 21 and the first jaw 23, and the second connecting rod 22 and the second jaw 24, in this embodiment, a third rotating shaft 6 is hingedly provided at the other ends of the first connecting rod 21 and the second connecting rod 22.

That is, after the cylindrical target is clamped, the third rotating shaft 6 is clamped in the bayonet 71 to prevent the first connecting rod 21 and the second connecting rod 22 from rotating. In this way, it is ensured that the cylindrical target is always in a clamped state during the handling process.

[0027] Further, to facilitate the design of the sling assembly 1, in this embodiment, the sling assembly 1 includes a base 11 and a sling 12. Among them, a first rotating shaft 4 is passed through the bottom of the base 11, and the sling 12 is threadedly connected to the top of the base 11. To ensure that the sling 12 and the base 11 have good structural strength, in this embodiment, both the sling 12 and the base 11 are made of stainless steel materials.

[0028] Furthermore, to facilitate the design of the second rotating shaft 5 and the third rotating shaft 6, in this embodiment, both the second rotating shaft 5 and the third rotating shaft 6 include a set screw 51, a locking nut 52, and a limit steel sleeve 53. A locking nut 52 is provided at the end of the set screw 51. Among them, a limit steel sleeve 53 is sleeved on the optical axis section of the set screw 51. To prevent axial movement between the jaw assemblies 2 and affect the stability when clamping the cylindrical target, therefore, further refer to Figure 1 , Figure 2 , limit bolts 8 are passed through between two adjacent first jaws 23 and between two adjacent second jaws 24.

[0029] In summary, the embodiment of the present utility model provides a handling jig for a cylindrical target. By setting the sling assembly 1, it can be quickly connected to a lifting tool, facilitating the handling of the cylindrical target. The jaw assembly 2 includes a first connecting rod 21, a second connecting rod 22, a first jaw 23, and a second jaw 24. The first connecting rod 21 is hinged to the first jaw 23, and the second connecting rod 22 is hinged to the second jaw 24. The first connecting rod 21 and the second connecting rod 22 rotate synchronously, which can drive the first clamping portion 231 and the second clamping portion 241 to approach or move away from each other, thereby clamping the transportation target; and a flexible gasket assembly 3 is provided on the first clamping portion 231, the second rotating shaft 5, and the second clamping portion 241. When handling the cylindrical target, the flexible gasket assembly 3 contacts the outer wall of the cylindrical target, preventing scratches on the outer wall of the cylindrical target during handling, and clamping the cylindrical target, reducing the manual labor intensity and reducing the risk of the cylindrical target being knocked and dropped.
