[0026] Specifically, the pulling mechanism 5 includes two symmetrically arranged sliding legs 51, and a sliding groove 11 for the two sliding legs 51 to slide is opened inside the workbench 1. The upper end of the sliding leg 51 is fixedly connected to a magnet 1 52, and the top height of the magnet 1 52 does not exceed the top height of the workbench 1, so that the magnet 1 52 can slide to the bottom of the woven bag. A connecting plate 53 is fixedly connected between the two sliding legs 51, and a cover plate 54 is hinged on the top of the connecting plate 53. Both ends of the cover plate 54 are fixedly connected to magnet 2 55, and the top of the cover plate 54 is fixedly connected to a handle 56. The two magnets 2 55 are respectively connected to the two Magnet one 52 corresponds to magnet one 52, and magnet two 55 and magnet one 52 have opposite poles. Pulling handle 56 drives the pulling mechanism 5 to slide as a whole. The pulling mechanism 5 slides until one end of the woven bag contacts the side of the connecting plate 53. At this time, magnet one 52 is located at the bottom of the woven bag. The cover plate 54 is turned by handle 56 to close. At this time, magnet two 55 is located at the top of the woven bag. Magnet two 55 and magnet one 52 can clamp and fix the woven bag with magnetic force. Continue to pull handle 56 to drive the woven bag to slide. When the sliding leg 51 is against the positioning plate 3, the cutting piece 2 can be driven to cut the woven bag.

[0027] More specifically, the adjustment mechanism 4 includes a threaded rod 41, and an adjustment groove 42 for the threaded rod 41 to rotate is opened on one side of the workbench 1.
