Description

Technical Field

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

[0002] Pruning shears (also known as gardening shears or branch shears) are manual cutting tools specifically designed for pruning plant branches, buds, or dead branches. They are widely used in horticulture, agriculture, forestry, and other fields. Designed to meet the needs of cutting plant stems, they are more labor-saving and precise than ordinary scissors, and long-handled pruning shears are one type.

[0003] Currently, existing landscaping pruning shears are prone to slipping when encountering thick or hard branches during pruning. If the blade slips or suddenly breaks, the long handle may rebound due to the reaction force, causing the hand to be hit by the handle end, or the tool may become uncontrollable and fall on the body. To address this, we propose a new type of landscaping pruning shear. Utility Model Content

[0004] The purpose of this utility model is to provide a greening pruning shears that is convenient to use, anti-slip, and safe to use. It solves the problem that existing greening pruning shears are prone to slipping when encountering thick or hard branches during pruning. If the blade slips or suddenly breaks, the long handle may rebound due to the reaction force, causing the hand to be hit by the handle end, or the tool may be out of control and fall on the body.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pruning shears for landscaping, comprising:

[0006] The first shear body has a first oblique shallow hook groove on its top contact surface;

[0007] The second shear body has a second oblique shallow hook groove on its bottom contact surface;

[0008] A connecting pin is hinged to the first and second shear bodies, and a handle is fixedly connected to one end of each of the first and second shear bodies.

[0009] Preferably, the ends of the first and second shears near the handle have an upwardly curved structure.

[0010] Preferably, the first and second oblique shallow hook grooves are inclined at a 45-degree angle to the cutting edges of the first and second shear bodies, respectively, and the first and second oblique shallow hook grooves are each grouped in sets of three, and multiple sets of the first and second oblique shallow hook grooves on the first and second shear bodies are distributed.

[0011] Preferably, the outer surface of the grip is coated with an anti-slip rubber sleeve.

[0012] Preferably, rubber buffer blocks are fixedly connected to the inner sides of both the first and second shear bodies near the handle end.

[0013] Preferably, an annular groove is formed on the outer surface of one end of the handle, and a ring sleeve is slidably connected in the annular groove on the handle surface of one end of the first scissor body. A connecting strap is provided at the bottom of the ring sleeve, and a retaining sleeve is fixedly connected to one end of the connecting strap, and the retaining sleeve is adapted to the annular groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention can increase friction and reduce branch slippage. By segmenting the shearing process, the buffering force is released. The shearing process changes from a one-time break to a gradual slicing, thereby extending the force application time, reducing the peak value of the instantaneous reaction force, making it convenient for workers to use, and preventing slippage and improving safety.

[0025] Example 1

[0026] Please see Figures 1-5 As shown, this utility model provides a technical solution: a pruning shears for landscaping, comprising:

[0027] The first shear body 1 has a first oblique shallow hook groove 101 on its top contact surface;

[0028] The second shear body 2 has a second oblique shallow hook groove 201 on its bottom contact surface;

[0029] A connecting pin 3 is hinged to the first shear body 1 and the second shear body 2. A handle 5 is fixedly connected to one end of both the first shear body 1 and the second shear body 2.

[0030] The first shear body 1 and the second shear body 2 have an upward curved structure at the end near the handle 5. The first oblique shallow hook groove 101 and the second oblique shallow hook groove 201 are inclined at a 45-degree angle to the cutting edge of the first shear body 1 and the second shear body 2, respectively. The first oblique shallow hook groove 101 and the second oblique shallow hook groove 201 are all in groups of three, and there are multiple groups of the first oblique shallow hook groove 101 on the first shear body 1 and the second oblique shallow hook groove 201 on the second shear body 2.

[0031] This technical solution: By designing the first shear body 1 and the second shear body 2 with an upwardly curved structure near the handle 5, this pruning shears makes it easier to prune and shape green plants. When the pruning shears are turned upside down, the handle 5 points downward, making it easier to prune green plants in an arc shape (some products on the market have similar designs). The first oblique shallow hook groove 101 and the second oblique shallow hook groove 201 respectively on the contact surfaces of the first shear body 1 and the second shear body 2 increase friction and reduce branch slippage. The core reason for branch slippage is insufficient friction between the blade and the branch surface (especially on smooth branches or when the blade is worn). The first oblique shallow hook groove 101 and the second oblique shallow hook groove 201 can embed into the branch's epidermis or xylem, forming a mechanical interlocking point, similar to the anti-slip principle of tire treads, preventing the branch from sliding along the blade surface during pruning. Simultaneously, for branches with sap, the grooves can accommodate some of the sap, preventing the liquid from forming a lubricating layer on the blade surface, indirectly reducing slippage. When pruning thick, stiff branches, the magnitude of the reaction force if suddenly cut is related to the shearing speed and the branch's toughness. The first and second oblique shallow hook grooves 101 and 201 can release the buffer force through segmented shearing. Furthermore, the first and second oblique shallow hook grooves 101 and 201 will first cut the surface fibers of the branch, changing the shearing process from a one-time break to a gradual slicing, thereby prolonging the force's duration and reducing the peak value of the instantaneous reaction force. The sharp edges of the grooves can increase the resistance points on the branch, even if... Even if the branch is not completely cut off, the groove can slow down the speed at which it suddenly detaches, reducing the violent rebound of the tool due to the loss of its force point. In addition, the shallow hook grooves 101 and 201 have a limited reduction in the sharpness of the cutting edge due to their shallowness. The depth of the first and second shallow hook grooves 101 and 201 is 0.5-1mm, the spacing is 3-5mm, and the three are grouped together, with the spacing between groups between 3-5cm, thus preventing an increase in shearing resistance.

[0032] Example 2

[0033] Based on Embodiment 1, this utility model is as follows: Figures 1-5 As shown, the outer surface of the grip 5 is covered with an anti-slip rubber sleeve 501.

[0034] This technical solution improves the anti-slip performance of the pruning shears by using the anti-slip rubber sleeve 501.

[0035] Example 3

[0036] Based on Embodiment 1, this utility model is as follows: Figures 1-5 As shown, rubber buffer blocks 4 are fixedly connected to the inner side of the first shear body 1 and the second shear body 2 near the handle 5.

[0037] This technical solution: By setting the rubber buffer block 4, it can provide a limiting and buffering capability when the first shear body 1 and the second shear body 2 are combined.

[0038] Example 4

[0039] Based on Embodiment 1, this utility model is as follows: Figures 1-5 As shown, an annular groove 6 is provided on the outer surface of one end of the handle 5. A ring sleeve 601 is slidably connected in the annular groove 6 on the surface of the handle 5 at one end of the first shear body 1. A connecting strap 602 is provided at the bottom of the ring sleeve 601. A retaining sleeve 603 is fixedly connected to one end of the connecting strap 602, and the retaining sleeve 603 is adapted to the annular groove 6.

[0040] This technical solution: By setting the ring 601 and the ring groove 6, when the pruning shears are not in use, the sleeve 603 can be inserted into the ring groove 6 on the surface of the handle 5 at one end of the second shear body 2, and with the assistance of the connecting strap 602, the first shear body 1 and the second shear body 2 are positioned, avoiding the opening and closing of the pruning shears during carrying and reducing the risk of carrying them.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
