Abstract
Description
Technical Field
[0001] This utility model relates to the field of herb harvesting technology, and in particular to a handheld herb harvesting shear. Background Technology
[0002] Herbs, also known as medicinal plants, refer to plants with medicinal value. Some herbs require scissors to cut them down, as they cannot be picked by hand. However, some herbs grow on trees, requiring workers to use ladders to harvest them. Most scissors are too small, making the harvesting of herbs difficult. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a handheld harvesting shear for herbs.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A handheld harvesting shears for herbs includes a handle, a telescopic rod that is slidably disposed inside the handle, a connecting post that is connected to one end of the telescopic rod, a sickle blade that is mounted on the connecting post, and blades that are symmetrically disposed on one end of the handle at the side of the sickle blade.
[0006] The handle is tubular in shape, with a movable groove on the outer wall of the handle tube. Support holes are symmetrically provided on both sides of the movable groove inside the handle tube. The telescopic rod slides in the support holes. A limit hole is provided inside the end of the handle tube near the blade.
[0007] In addition, a preferred structure is that a limiting post is fixedly connected to the side of the limiting hole away from the supporting hole, and the telescopic rod is arranged to slide inside the limiting post.
[0008] In addition, a preferred structure is that the limiting post is provided with a movable hole, and the telescopic rod is located at the movable hole.
[0009] In addition, a preferred structure is that a limiting protrusion is provided on the outer wall of the end of the telescopic rod away from the connecting column, the limiting protrusion is movably disposed in the movable groove, and a limiting protrusion is provided on the outer wall of the telescopic rod near the connecting column.
[0010] In addition, a preferred structure is that a spring is fixedly connected to one side of the limiting hole, and the other end of the spring away from the limiting hole is fixedly connected to the connecting post.
[0011] In addition, a preferred structure is that the connecting post has a screw hole, and the sickle blade is installed in the screw hole.
[0012] Furthermore, in a preferred configuration, a screw seat is provided on the sickle blade, and the screw seat is screwed into the screw hole.
[0013] In addition, a preferred configuration is that a rubber sleeve is provided on the outer wall of the handle located in the movable groove.
[0014] The beneficial effects of this utility model are as follows: By setting a telescopic lever on the handle, when harvesting herbs, the handle is extended so that the sickle blade is on one side of the herbs. Then, by moving the telescopic lever, the sickle blade and the blade can be overlapped for harvesting. This handle is long enough to harvest herbs over a greater distance. Moreover, it is simpler to operate than scissors, making it more efficient for operators when harvesting herbs. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] Reference Figure 1-9 A handheld harvesting shears for herbs includes a handle 1, a telescopic rod 7 slidably disposed inside the handle 1, a connecting post 5 connected to one end of the telescopic rod 7, a sickle blade 4 on the connecting post 5, and blades 3 symmetrically disposed on one end of the handle 1 near the sickle blade 4. The handle 1 is tubular in shape, with a movable groove 11 on the outer wall of the handle 1 tubular body, and support holes 12 symmetrically disposed on both sides of the movable groove 11 inside the handle 1 tubular body. The telescopic rod 7 is slidably fitted at the support holes 12, and a limit hole 13 is disposed inside the handle 1 tubular body near the blade 3. The handle 1 can realize the linear movement of the sickle blade 4, thereby overlapping with the blade 3 for harvesting.
[0027] Among them, the limiting hole 13 is fixedly connected to the limiting post 8 on the other side away from the support hole 12, and the telescopic rod 7 is installed inside the limiting post 8 to slide. The limiting post 8 is provided with a movable hole 81, and the telescopic rod 7 is installed at the movable hole 81. The telescopic rod 7 and the limiting post 8 can limit the distance of the telescopic rod 7 to move.
[0028] Furthermore, a limiting protrusion 71 is provided on the outer wall of the telescopic rod 7 on the other side away from the connecting column 5. The limiting protrusion 71 is movably disposed in the movable groove 11. The telescopic rod 7 is provided on the outer wall near the connecting column 5. The operator can move the telescopic rod 7 by oscillating the limiting protrusion 71.
[0029] Meanwhile, a spring 6 is fixedly connected to one side of the limiting hole 13, and the other end of the spring 6 away from the limiting hole 13 is fixedly connected to the connecting post 5. The spring 6 can release elastic potential energy, thereby resetting the pulled and contracted connecting post 5.
[0030] In addition, a screw hole 51 is provided on the connecting column 5, and the sickle blade 4 is installed in the screw hole 51. The sickle blade 4 is used to harvest herbs.
[0031] In addition, a screw seat 41 is provided on the sickle blade 4. The screw seat 41 is screwed into the screw hole 51, and the screw seat 41 is used so that the sickle blade 4 can be screwed onto the connecting post 5.
[0032] Among them, a rubber sleeve 2 is provided on the outer wall of the handle 1 located in the movable groove 11. The rubber sleeve 2 can increase the friction between the handle 1 and the operator's hand when the operator holds the handle 1.
[0033] In this embodiment, when using the harvesting shears to cut herbs, the person holds the rubber sleeve 2, extends the sickle blade 4 to one side of the herb, and then presses the limiting protrusion 71, causing the limiting protrusion 71 to oscillate to one side, thereby enabling the telescopic rod 7 to move at the support hole 12. The telescopic rod 7 pulls the connecting post 5, and the sickle blade 4 on the connecting post 5 slowly moves into the gap between the two blades 3. When the sickle blade 4 moves to the gap between the two blades 3, it cuts the herb. The limiting ring 72 is restricted by the limiting post 8, effectively limiting the retraction distance of the telescopic rod 7.
[0034] After harvesting the herbs, release the hand that was holding the limiting protrusion 71. At this time, the contracted spring 6 releases its elastic potential energy without external pressure, which drives the connecting column 5 to return to its original position, thereby separating the sickle blade 4 from the blade 3.
[0035] Furthermore, the sickle blade 4 can be replaced periodically; simply unscrew the screw seat 41 from the screw hole 51.
[0036] In this utility model, by setting a telescopic lever 7 on the handle 1, when harvesting herbs, the handle 1 is extended so that the sickle blade 4 is located on one side of the herbs. Then, by moving the telescopic lever 7, the sickle blade 4 and the blade 3 can be overlapped for harvesting. This handle 1 is long and can harvest herbs over a greater distance. Moreover, it is simpler to operate than scissors, and the operator is more efficient when harvesting herbs.
[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
