[0038] First, start the motor driving mechanism 3, and the servo motor 21 starts to work. The cam disc 33 rotates to drive the push plate 36 on the table plate 12 to move upward via the connecting rod 34 and the connecting angle piece 35. In the process of upward sliding, the push block on the push plate 36 pushes the push lug of the vertical hook quick connection 2461, so that the entire vertical hook quick connection assembly 246 moves upward along the bottom plate 241 against the tension of the tension spring 2463 below. In this process, the vertical hook quick connection 2461 triggers the lower swing arm of the moving iron 245 to rotate the moving iron 245, and at the same time, the upper swing arm of the moving iron 245 swings until it hits and contacts the electromagnet 243. Then, the servo motor 21 rotates to reset the push plate 36, and under the action of the tension spring 2463, the vertical hook quick connection 2461 is reset downward to separate from the moving iron 245, and at the same time, the moving iron 245 is reset under the action of the spring 244.

[0039] In summary, the application has stable and reliable operation, efficient and compact action process, and can realize the repetitive action of the moving iron hitting test of the jacquard machine, and provides strong experimental support for the research and development and production of jacquard machine assemblies.
