Description

Technical Field

[0001] This utility model relates to the field of agricultural implements technology, specifically to an adjustable spring-loaded harvesting shear. Background Technology

[0002] While existing harvesting shears employ a spring-loaded return design, allowing them to automatically return to their original shape after cutting, most designs do not consider how to adjust the starting distance for triggering this return when the shears come together, adapting to actual usage. Typically, during cutting, a spring or other elastic element only activates when the two blades reach a fixed position, pushing the blades apart to return to their original shape. However, this position is usually fixed and cannot adapt to different usage needs. For example, when cutting branches or fruits of varying thicknesses, a rigidly fixed trigger point can lead to uneven cutting or excessive cutting force.

[0003] Meanwhile, most harvesting shears are inconvenient to store after use. Because the blade and handle are relatively fixed in structure, and most lack a folding or retractable mechanism, users often find it difficult to store the tools conveniently after harvesting. This is especially true in space-constrained environments such as backpacks or toolboxes, where the shears' size cannot be effectively reduced, resulting in them taking up too much space. Furthermore, the exposed blades increase safety hazards during storage and can easily scratch other items.

[0004] In particular, given the differences in hand size and grip strength between men and women, current harvesting shears on the market do not adequately consider this factor. This may require workers to increase their grip strength, which is not conducive to long hours of work or harvesting. At the same time, their practicality is also affected for users with smaller hands. Utility Model Content

[0005] To address the shortcomings of existing harvesting shears, such as the inability to adjust the elastic reset starting distance when the shears are brought close together for cutting, and their inconvenience in storage, this invention provides an adjustable spring-loaded harvesting shear, comprising: a blade body and a handle, the two blade bodies being hinged together to form a fork-shear combination, each blade body being connected to a handle for gripping, and each blade body having a cutting edge at the end away from the handle; an adjustable spring-loaded distance unit is provided inside any one of the blade bodies, the adjustable spring-loaded distance unit being used to adjust the elastic reset starting distance when the two blade bodies are brought close together for cutting.

[0006] Preferably, the adjustable springback distance unit includes a screw, a telescopic threaded sleeve, and an elastic element. The inner side of the cutter body is provided with a screw pointing axially to the other side of the cutter body. The screw is threadedly connected to a telescopic threaded sleeve, which is sleeved and installed outside the screw. A nut is sleeved and installed inside the telescopic threaded sleeve of the screw.

[0007] Preferably, the elastic element is an elastic hollow rubber ball, and a buffer pad adapted to the elastic element is detachably connected to the blade body without the adjustable rebound distance unit. The side of the buffer pad facing the elastic element is provided with a spherical concave guide groove.

[0008] Preferably, the handle is provided with an extension rod for increasing the length of the shearing power arm on the side away from the blade.

[0009] Preferably, the extension rod is provided with a concave relief groove adapted to the shape of the two blades, and when the two extension rods are rotated in opposite directions to the side of the corresponding blade, the blades are nested into the concave relief groove.

[0010] Preferably, the clearance groove is provided with a magnetic block that cooperates with the blade.

[0011] Preferably, the blade shape is an arc-shaped blade.

[0012] Compared with the prior art, this utility model provides an adjustable spring-loaded picking shear, which has the following beneficial effects:

[0013] 1. Adjustable rebound trigger mechanism

[0014] To address the issue of the non-adjustable starting distance for scissor reset in existing technologies, this invention employs an adjustable elastic reset mechanism. By adjusting the position of the telescopic threaded sleeve, the relative position of the elastic element is changed, thereby adjusting the starting distance at which the blade triggers elastic reset when it comes together. Users can easily adjust this distance according to their actual needs, ensuring moderate cutting force during shearing and avoiding fruit damage or incomplete shearing due to excessive shearing force.

[0015] 2. Convenient storage structure

[0016] To improve the ease of storage for the scissors, this invention incorporates a folding mechanism in the handle. Specifically, the scissors handle features a foldable structure, allowing it to rotate and fold along a specific axis, reducing the tool's size. The folding mechanism is magnetically designed, enabling users to easily fold the blade and handle together for storage when not in use. This not only reduces the space occupied by the scissors but also prevents the blade from being exposed, ensuring safety during storage. Attached Figure Description
