Description
* GARDEMNG SHEARS HAVING ENERGY-SAV[NG FUNCTION The present invention relates to a gardening cutting tool and, more particularly, to a pair of gardening shears for shearing a plant.
A gardening cutting tool, such as a pair of gardening shears, is used to cut or shear a plant, such as the branches of a tree, in an energy-saving manner, thereby facilitating a user operating the gardening cutting tool. A pair of conventional gardening shears in accordance with the prior art shown in Figs. 8 and 9 comprise a metallic plate 60, a first elongate member 70 and a second elongate member 80. The metallic plate 60 has a first end provided with a first cutting portion 62, a mediate portion provided with a first pivot member 61 and a second end 63 provided with a second pivot member 64 spaced from the first pivot member 61. The first elongate member 70 is pivotally connected with the first pivot member 61 of the metallic plate 60 and has a first end provided with a second cutting portion 71 that is movable relative to the first cutting portion 62 of the metallic plate 60, a mediate portion provided with a first gear portion 73 and a second end provided with a first extension 72. The second elongate member 80 is pivotally connected with the second pivot member 64 of the metallic plate 60 and has a first end provided with a second gear portion 82 meshing with the first gear portion 73 of the first elongate member 70 and a second end provided with a second extension 81.
In operation, the second gear portion 82 of the second elongate member 80 meshes with the first gear portion 73 of the first elongate member so that when the second elongate member 80 is pivoted relative to the first elongate member 70, the metallic plate 60 is driven by the second elongate member 80 to pivot relative to the first elongate member 70, and the first cutting portion 62 of the metallic plate 60 is moved relative to the second cutting portion 71 of the first elongate member 70. Thus, the first cutting portion 62 of the metallic plate 60 is moved relative to the second cutting portion 71 of the first elongate member 70 from the opened position as shown in Fig. 9 to the closed position as shown in Fig. 8 to perform a cutting or shearing action so as to cut or prune a plant and the like.
However, the first elongate member 70 and the second elongate member 80 are mounted on one side of the metallic plate 60 so that when the first elongate member 70 and the second elongate member 80 are subjected to a reaction, the reaction is concentrated on the meshing portion of the first elongate member 70 and the second elongate member 80, thereby affecting operation of the first elongate member 70 and the second elongate member 80.
In addition, the movement between the first elongate member 70 and the second elongate member 80 is not limited properly so that the second elongate member 80 is easily pivoted outward relative to the first elongate member 70 to an excessive extent and caimot be returned to the original position easily and quickly, thereby causing inconvenience to a user when he wishes to drive the second elongate member 80 toward the first elongate member 70.
In accordance with the present invention, there is provided a pair of gardening shears, comprising a main cutter, a secondary cutter pivotally connected with the main cutter, two force arms pivotally connected with the main cutter, a pad secured on the two force arms, and a drive plate secured on the two force arms to move in concert with the two force arms.
The main cutter has a first end provided with a first handle and a second end provided with a first cutting portion. The main cutter has a mediate portion provided with a first pivot hole and a first pivot bore. The secondary cutter has a mediate portion provided with a second pivot hole and a guide slot.
The second pivot hole of the secondary cutter is pivotally connected with the first pivot hole of the main cutter. The secondary cutter has a first end provided with an elongate extension and a second end provided with a second cutting portion. The extension of the secondary cutter has a bent distal end provided with a driven gear portion and has a side provided with a receiving space which is located between the driven gear portion and the extension. The two force arms are juxtaposed to each other and abut the main cutter and the secondary cutter. The main cutter and the secondary cutter are sandwiched between the two force arms. Each of the two force arms has a first end provided with a second handle and a second end provided with a second pivot bore. The second pivot bore of each of the two force arms is pivotally connected with the first pivot bore of the main cutter by a pivot member. The guide slot of the secondary cutter is movable on the pivot member when the secondary cutter is pivotable relative to the main cutter. The pad laminates the drive plate. The pad and the drive plate are received in the receiving space of the secondary cutter and are located between the two force arms. The drive plate has a first side provided with a drive gear portion meshing with the driven gear portion of the secondary cutter so that the secondary cutter is movable in concert with the drive plate when the drive plate is movable in concert with the two force arms.
The drive plate has a second side provided with a protrusion abutting the pad.
The primary objective of the present invention is to provide a pair of gardening shears having an energy-saving function.
According to the primary objective of the present invention, the main cutter and the secondary cutter are sandwiched between the two force arms so that the reaction applied on the main cutter and the secondary cutter is distributed by the two force arms evenly and smoothly to prevent from incurring a stress concentration so as to facilitate operation and movement of the main cutter and the secondary cutter.
According to another objective of the present invention, when the secondary cutter is pivoted outward relative to the main cutter to the maximum extent, an end of the guide slot of the secondary cutter is stopped by the pivot member to stop a further outward movement of the secondary cutter relative to the main cutter so as to prevent the second cutting portion of the secondary cutter and the first cutting portion of the main cutter from being opened too broadly and extensively and to facilitate a user closing the second cutting portion of the secondary cutter and the first cutting portion of the main cutter.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.

* Referring to the drawings and initially to Figs. 1-3, a pair of gardening shears in accordance with the preferred embodiment of the present invention comprise a main cutter 10, a secondary cutter 20 pivotally connected with the main cutter 10, two force arms 50 pivotally connected with the main cutter 10, a pad 30 secured on the two force arms 50, and a drive plate 40 secured on the two force arms 50 to move in concert with the two force arms 50.
The main cutter 10 has a first end provided with a first handle 11 and a second end provided with a first cutting portion 14. The first cutting portion 14 of the main cutter 10 is a blade or an anvil. The main cutter 10 has a mediate portion provided with a first pivot hole 12 and a first pivot bore 13.
The secondary cutter 20 has a mediate portion provided with a second pivot hole 21 and a substantially arc-shaped guide slot 25. The second pivot hole 21 of the secondary cutter 20 is pivotally connected with the first pivot hole 12 of the main cutter 10. The secondary cutter 20 has a first end provided with an elongate extension 22 and a second end provided with a second cutting portion 26. The second cutting portion 26 of the secondary cutter 20 is a blade or an anvil. The extension 22 of the secondary cutter 20 has a bent distal end provided with a driven gear portion 23 and has a side provided with a receiving space 24 which is located between the driven gear portion 23 and the extension 22. The guide slot 25 of the secondary cutter 20 is disposed between the second pivot hole 21 and the receiving space 24 of the secondary cutter 20.
The two force arms 50 are juxtaposed to each other and abut the main cutter 10 and the secondary cutter 20 so that the main cutter 10 and the S secondary cutter 20 are sandwiched between the two force arms 50. Each of the two force arms 50 has a substantially Z-shaped cross-sectional profile and has a first end provided with a second handle 51 and a second end provided with a second pivot bore 52. The second pivot bore 52 of each of the two force arms 50 is pivotally connected with the first pivot bore 13 of the main cutter 10 by a pivot member 54, and the guide slot 25 of the secondary cutter 20 is movable on the pivot member 54 when the secondary cutter 20 is pivotable relative to the main cutter 10. The pivot member 54 in turn extends through the second pivot bore 52 of one of the two force arms 50, the guide slot 25 of the secondary cutter 20, the first pivot bore 13 of the main cutter 10 and the second pivot bore 52 of the other one of the two force arms 50. Each of the two force arms 50 has a mediate portion provided with two fixing holes 53.
The pad 30 and the drive plate 40 are received in the receiving space 24 of the secondary cutter 20 and are located between the two force arms 50 by two fastening members 55 to move in concert with the two force arms 50 when the two force arms 50 are pivoted relative to the main cutter 10. The two fastening members 55 are fixed in the two fixing holes 53 of each of the two force arms 50. The pad 30 laminates the drive plate 40 and is provided with two through holes 31 to allow passage of the two fastening members 55. The drive plate 40 has a first side provided with a substantially arc-shaped drive gear portion 41 meshing with the driven gear portion 23 of the secondary cutter so that the secondary cutter 20 is movable in concert with the drive plate 40 when the drive plate 40 is movable in concert with the two force arms 50. The drive plate 40 has a second side provided with a protrusion 42 abutting the pad 30. The protrusion 42 of the drive plate 40 is provided with two through bores 43 to allow passage of the two fastening members 55. The two fastening members 55 in turn extend through the two fixing holes 53 of one of the two force arms 50, the two through bores 43 of the drive plate 40, the two through holes 31 of the pad 30 and the two fixing holes 53 of the other one of the two force arms 50, so that the pad 30 and the drive plate 40 are fixed between the two force arms 50.
In operation, referring to Figs. 3 and 4 with reference to Figs. 1 and 2, the drive gear portion 41 of the drive plate 40 meshes with the driven gear portion 23 of the secondary cutter 20 so that the secondary cutter 20 is combined with the two force arms 50 by the drive plate 40 and is moved in concert with the drive plate 40 and the two force arms 50 when the drive plate is moved in concert with the two force arms 50.
In such a manner, when the two force arms 50 are pivoted outward relative to the main cutter 10, the drive plate 40 is moved by the two force arms 50, and the secondary cutter 20 is moved by the drive plate 40, so that the secondary cutter 20 is driven by the pivotal movement of the two force arms 50 and is pivoted outward relative to the main cutter 10 (with the second pivot hole 21 of the secondary cutter 20 and the first pivot hole 12 of the main cutter functioning as the pivot fulcrum) from the closed position as shown in Fig. 3 to the opened position as shown in Fig. 4. At this time, the guide slot 25 of the secondary cutter 20 is moved on the pivot member 54 when the secondary cutter 20 is pivoted relative to the main cutter 10 so that the pivot member 54 can guide movement of the secondary cutter 20 smoothly and stably.
On the contrary, when the two force arms 50 are pivoted toward the main cutter 10, the drive plate 40 is moved by the two force arms 50, and the secondary cutter 20 is moved by the drive plate 40, so that the secondary cutter is driven by the pivotal movement of the two force arms 50 and is pivoted toward the main cutter 10 from the opened position as shown in Fig. 4 to the closed position as shown in Fig. 3 until the second cutting portion 26 of the secondary cutter 20 abuts the first cutting portion 14 of the main cutter 10 to perform a cutting or shearing action so as to cut or prune a plant and the like.
As shown in Figs. 5 and 6, when the secondary cutter 20 is pivoted outward relative to the main cutter 10 to the maximum extent, an end of the guide slot 25 of the secondary cutter 20 is stopped by the pivot member 54 to stop a further outward movement of the secondary cutter 20 relative to the main cutter 10 so as to prevent the second cutting portion 26 of the secondary cutter 20 and the first cutting portion 14 of the main cutter 10 from being opened too broadly and extensively.
As shown in Fig. 7, the first cutting portion 14 of the main cutter 10 is a blade, and the second cutting portion 26 of the secondary cutter 20 is also a blade.
Accordingly, the main cutter 10 and the secondary cutter 20 are sandwiched between the two force arms 50 so that the reaction applied on the main cutter 10 and the secondary cutter 20 is distributed by the two force arms evenly and smoothly to prevent from incurring a stress concentration so as to facilitate operation and movement of the main cutter 10 and the secondary cutter 20. In addition, when the secondary cutter 20 is pivoted outward relative to the main cutter 10 to the maximum extent, an end of the guide slot 25 of the secondary cutter 20 is stopped by the pivot member 54 to stop a further outward movement of the secondary cutter 20 relative to the main cutter 10 so as to prevent the second cutting portion 26 of the secondary cutter 20 and the first cutting portion 14 of the main cutter 10 from being opened too broadly and extensively and to facilitate a user closing the second cutting portion 26 of the secondary cutter 20 and the first cutting portion 14 of the main cutter 10.
Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
