[0023] As Figure 1 and Figure 3 shown, the fishing mechanism comprises a horizontal fixed plate 2, the lower end of the horizontal fixed plate 2 is provided with a plurality of fishing teeth 1, the plurality of fishing teeth 1 are evenly arranged on the horizontal fixed plate 2, and the arranged fishing teeth 1 form a horizontal water grass containing space, the horizontal section of the fishing teeth 1 can be appropriately lengthened to increase the water grass fishing capacity. The upper end of the fishing teeth 1 is provided with a threaded section, the horizontal fixed plate 2 is provided with a through hole for inserting the threaded section, the lower end of the threaded section is provided with a limit ring, the threaded section passes through the through hole and is locked on the through hole by the nut 13, and the fishing teeth 1 are convenient to replace when damaged.
[0024] As Figure 1 , Figure 2 and Figure 4As shown, the drive mechanism includes a drive support base 15. The upper end of the drive support base 15 is fixed to the lower end of the mounting beam 9 by two crossbeams 12. The crossbeams 12 and the mounting beam 9 form a grid shape to improve the support strength of the entire device. A drive telescopic rod 11 is provided in the gap between the two crossbeams 12. The drive telescopic rod 11 can be an electric telescopic rod or a hydraulic telescopic rod. The drive telescopic rod 11 is rotatably mounted on the drive support base 15. A drive shaft 4 perpendicular to the swing direction of the salvage mechanism is provided at the lower end of the drive support base 15. Both ends of the drive shaft 4 are mounted on bearing seats 6. The drive shaft 4 is rotatably connected to the bearings in the bearing seats 6. Swing arms 3 are fixedly mounted at both ends of the drive shaft 4. The swing arms 3 are fixedly connected to the horizontal fixed plate 2. A swing connecting rod 14 is fixedly connected to the middle of the drive shaft 4. A connecting ring 5 is provided on the swing connecting rod 14 and is sleeved on the drive shaft 4 for fixed connection. The end of the swing connecting rod 14 is hinged to the end of the drive telescopic rod 11.
