Description

Technical Field

[0001] This utility model relates to the field of garden tool technology, specifically to a garden shears for pruning. Background Technology

[0002] In garden pruning, garden shears are an indispensable tool. Traditional garden pruning shears typically consist of two blades hinged together by a pin, with a handle driving the blades to close and cut branches. While such tools can perform the cutting action, they have the following technical problems:

[0003] Branches scattered after pruning: Existing scissors only have a cutting function. The cut branches fall directly to the ground or among the leaves due to gravity, requiring secondary manual cleaning. This is especially in areas at height or with dense branches, resulting in low collection efficiency and safety hazards.

[0004] Additional steps increase labor intensity: After pruning, it is necessary to frequently bend over or climb to collect branches, resulting in a cumbersome work process and high physical exertion.

[0005] Therefore, a garden shear that can simultaneously perform cutting and clamping actions urgently needs to be studied. Utility Model Content

[0006] The purpose of this utility model is to solve the problems mentioned in the background art and provide a garden pruning shears that, without increasing the complexity of pruning operations or significantly increasing weight, achieves simultaneous cutting and clamping through structural improvements, preventing cut branches from scattering and reducing subsequent cleaning procedures.

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a garden pruning shears, including a shear head and a handle, wherein the shear head includes a first blade and a second blade, and the handle includes a first handle and a second handle, wherein the end of the first blade is fixedly connected to the front end of the first handle, and the end of the second blade is fixedly connected to the front end of the second handle, and the first blade and the second blade are hinged by a pin.

[0008] A clamping structure is provided on the inner side of the first blade and the outer side of the second blade. The clamping structure includes a plurality of connecting posts fixedly connected to the first blade and the second blade. The top of the connecting post is provided with a clamping part, which is located on the inner side of the connecting post. The clamping part is made of elastic material.

[0009] The clamping part forms an outwardly convex arc shape between two adjacent connecting posts, and several clamping cavities are formed between the two clamping parts;

[0010] A tension spring is fixed between the two handles. The tension spring is located on the handle near the ends of the first and second blades. The tension spring is used to keep the shear head closed so that the clamping part is closed, thereby clamping the pruned branch.

[0011] As a preferred embodiment, the connecting post is connected to the first blade and the second blade by welding or riveting.

[0012] As a preferred embodiment, the handle is made of wood, and a metal reinforcing ring is fitted at the connection between the handle and the first and second blades.

[0013] As a preferred embodiment, the outer side of the handle is provided with an anti-slip layer.

[0014] As a preferred embodiment, the anti-slip layer is made of rubber, and the anti-slip layer has anti-slip texture on the outside.

[0015] The advantages of this invention compared to existing technologies are as follows: Shearing and clamping are completed simultaneously. The elastic clamping part is linked to the blade, automatically clamping the branch at the end of the shearing action, requiring no additional operation. It adapts to branches of varying thicknesses; the arc-shaped clamping cavity design combined with elastic material can accommodate the clamping needs of branches of different thicknesses. Operation is convenient; a tension spring assists in resetting, reducing hand fatigue, and the non-slip handle ensures effective transmission of shearing force. Structural reliability is ensured; the metal reinforcing ring and welding / riveting connection methods guarantee structural stability during long-term use. Attached Figure Description

[0024] Referring to the accompanying drawings, a garden pruning shears includes a shear head and a handle. The shear head includes a first blade 1 and a second blade 2. The handle includes a first handle 3 and a second handle 4. The end of the first blade 1 is fixedly connected to the front end of the first handle 3, and the end of the second blade 2 is fixedly connected to the front end of the second handle 4. The first blade 1 and the second blade 2 are hinged by a pin 5.

[0025] A clamping structure is provided on the inner side of the first blade 1 and the outer side of the second blade 2. The clamping structure includes a plurality of connecting posts 6 fixedly connected to the first blade 1 and the second blade 2. A clamping part 7 is provided at the top of the connecting post 6. The clamping part 7 is located on the inner side of the connecting post 6 and is made of elastic material.

[0026] The clamping part 7 forms an outwardly convex arc shape between two adjacent connecting posts 6, and a plurality of clamping cavities 8 are formed between the two clamping parts 7;

[0027] A tension spring 9 is fixed between the two handles, and the tension spring 9 is located on the handle near the ends of the first blade 1 and the second blade 2.

[0028] The connection between the connecting column 6 and the first blade 1 and the second blade 2 is by welding or riveting.

[0029] The handle is made of wood, and a metal reinforcing ring 10 is fitted at the connection between the handle and the first blade 1 and the second blade 2.

[0030] The handle has an anti-slip layer on the outside.

[0031] The anti-slip layer is made of rubber, and the outside of the anti-slip layer has anti-slip texture.

[0032] In specific implementation of this utility model:

[0033] 1. Design of connecting column 6 and clamping part 7:

[0034] Several longitudinally arranged connecting posts 6 (e.g., Φ3mm stainless steel rivets) are welded or riveted to the inner side of the first blade 1 and the outer side of the second blade 2. The top of the connecting posts 6 is fixed with an elastic clamping part (preferably made of rubber or silicone with a Shore hardness of 50A-70A).

[0035] The clamping part 7 protrudes outward between adjacent connecting posts 6 to form an arc-shaped structure. When the two blades are closed, the clamping parts 7 of the first blade 1 and the second blade 2 press against each other to form multiple independent clamping cavities 8 (the size range is Φ5mm-Φ15mm, which can accommodate branches of different thicknesses).

[0036] 2. Dynamic clamping principle:

[0037] Cutting stage: The handle applies force to close the blade, and the blade cuts the branch; at this time, the branch is located between the two blades, and the clamping part 7 wraps around the surface of the branch due to elastic deformation.

[0038] Clamping stage: After the cutting is completed, the tension spring 9 rebounds and the handle opens slightly, increasing the distance between the blades. However, the clamping cavity 8 remains in close contact with the branch surface due to the deformation recovery force of the elastic clamping part 7, forming friction to fix it.

[0039] Release phase: The handle is further opened, the clamping cavity 8 is completely separated, and the branch is detached.

[0040] Auxiliary structure optimization

[0041] Handle reinforcement design: The handle is made of lightweight hardwood (such as beech) and a metal reinforcing ring 10 (such as a 65Mn spring steel ring) is fitted at the connection with the blade to prevent the wooden handle from cracking.

[0042] Anti-slip layer: The outer surface of the handle is covered with a rubber layer (2mm thick) with diamond-shaped anti-slip texture to enhance grip stability.

[0043] Example 1

[0044] Component selection and assembly:

[0045] The blade is made of 65Mn spring steel and is quenched and tempered to HRC45-50; the connecting post 6 is made of Φ3mm stainless steel rivets, evenly distributed at a spacing of 15mm; the clamping part 7 is made of silicone with a Shore hardness of 60A and has 4 clamping cavities 8 on one side; the tension spring 9 is made of stainless steel compression spring with a wire diameter of 1.2mm and a free length of 50mm.

[0046] Workflow:

[0047] Initial state: The tension spring 9 is in its natural extension state, the handle is open, and the blade is separated.

[0048] Cutting action: Grip the handle tightly, the blade closes to complete the cutting, and at this time the branch is wrapped by the clamping cavity 8.

[0049] Maintaining the state: Slightly loosen the handle (the spring 9 rebounds, increasing the blade gap by 1-2mm), while the clamping part 7 remains firmly attached to the branch.

[0050] Branch collection: Move the shears over the collection container and fully open the handles to release the branch.

[0051] Example 2: Optimization of Clamping Structure

[0052] For thicker branches (Φ10mm and above), the number of connecting posts 6 can be increased to 6. The clamping cavity 8 is designed with a gradually changing diameter (Φ8mm-Φ15mm). The clamping part 7 adopts a double-layer composite structure (inner layer silicone + outer layer nylon woven mesh reinforcement).

[0053] In this invention, the elastic deformation of the clamping part is controlled by designing the material hardness and arc curvature to ensure that the shearing force is sufficient to deform the clamping part and wrap around the branch, while providing sufficient holding force. The tension spring parameters are matched: the spring stiffness must be coordinated with the elasticity of the clamping part to avoid excessively rapid rebound that could cause the branch to fall off.

[0054] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
