[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Reference Figure 1-Figure 4 The utility model provides an embodiment: a curved-handle mushroom cutting knife, comprising a slide bar 1, a first rotating shaft 2 is rotatably connected to the slide bar 1, one end of the first rotating shaft 2 is fixedly connected to a handle 3, a worm 4 is fixedly connected to the first rotating shaft 2, a worm wheel 5 is meshedly connected to the worm 4, a second rotating shaft 6 is fixedly connected to the worm wheel 5, the second rotating shaft 6 is rotatably connected to the slide bar 1, a sprocket 7 is fixedly connected to the second rotating shaft 6, a chain 8 is meshedly connected to the sprocket 7, a sprocket 9 is meshedly connected to the chain 8, a third rotating shaft 10 is fixedly connected to the sprocket 9, and the third rotating shaft 10 is rotatably connected to the slide bar 1, a cutter head 11 is fixedly connected to the third rotating shaft 10, a placing shell 12 is fixedly connected to the slide bar 1, and a slide bar 19 is fixedly connected to the slide bar 1. When using the curved handle mushroom cutting knife, the cutter head 11 can be easily adjusted to a comfortable angle by twisting the handle 1 3, so that the pickers can flexibly adjust the angle of the cutter head 11 according to the growth position and posture of the mushrooms, so as to pick the mushrooms in a more labor-saving and more comfortable posture, which not only reduces the physical exertion of the pickers due to improper posture during the picking process, improves the picking efficiency, but also increases the comfort of picking and reduces the fatigue of picking work.
[0023] The slide bar 1 is threadedly connected with a threaded screw 15, one end of which is fixedly connected with a cylinder 16, and the cylinder 16 is fixedly connected with a handle 2 17, and the handle 2 17 is provided with a rubber ball 18. The slide bar 1 is slidably connected with a sleeve 13, and the sleeve 13 is provided with a groove 14, and the sleeve 13 is provided with a slide groove 20. The cylinder 16 is rotatably connected to the groove 14, and the slide bar 19 is slidably connected to the slide groove 20. The slide bar 1 is arranged in the sleeve 13, the threaded screw 15 is arranged in the slide bar 19, and the groove 14 is arranged in the sleeve The slide groove 20 is arranged in the sleeve 13, the third rotating shaft 10 passes through the slide rod 1, and the first rotating shaft 2 passes through the slide rod 1. When using the curved handle mushroom cutting knife, the height of the cutter head 11 can be conveniently adjusted by twisting the handle 2 17, so that the pickers can quickly adjust the position of the cutter head 11 according to the actual growth height of the mushrooms, so as to cut the mushrooms more accurately, thereby improving the flexibility and adaptability of picking, and allowing the pickers to easily deal with mushrooms of various heights, thereby improving the picking efficiency and picking quality.
[0024] Working principle: when using the curved-handle mushroom cutting knife, the staff first twists the handle 3 according to the on-site conditions of picking mushrooms, the handle 3 drives the first rotating shaft 2 to rotate on the slide bar 1, the first rotating shaft 2 drives the worm 4 to rotate, the worm 4 drives the worm wheel 5 to rotate, the worm wheel 5 drives the second rotating shaft 6 to rotate on the slide bar 1, the second rotating shaft 6 drives the sprocket 7 to rotate, the sprocket 7 drives the chain 8 to rotate through meshing, the chain 8 drives the sprocket 2 9 to rotate through meshing, the sprocket 2 9 drives the third rotating shaft 10 to rotate on the slide bar 1, so that the third rotating shaft 10 drives the cutter head 11 to adjust, and stop twisting the handle 3 when it is adjusted to a comfortable angle for the pickers, which is used to adjust the cutter head 11 to various angles during picking, so that the pickers can pick the mushrooms more conveniently, which not only reduces the physical exertion of the pickers due to various postures during picking, but also greatly increases the picking efficiency of the mushrooms. When the mushrooms grow too high, the pickers only need to twist the handle 17, and the handle 17 drives the cylinder 16 to rotate in the groove 14 on the sleeve 13, and the cylinder 16 drives the threaded screw 15 to rotate. The threaded screw 15 drives the slide bar 1 through the slide bar 19 to move upward on the slide groove 20 through the threaded connection, which is used to adjust the height of the cutter head 11 according to the height of the mushrooms to be picked on site, so as to facilitate the pickers to pick mushrooms of various heights. In addition, a plurality of groups of rubber balls 18 are provided on the handle 17, which are used to slide when the pickers wear gloves to twist the handle 17. When the mushrooms are not picked, the staff twists the handle 3 in the opposite direction, and the handle 3 drives the cutter head 11 on the third rotating shaft 10 to move through the rotation of the chain 8. When the cutter head 11 is stuck in the placement shell 12, it is used to retract the cutter head 11 when not picking, so as to prevent the pickers from being injured due to the exposure of the cutter head 11.
