Description
GARDENING SHEARS WITH ENERGY-SAVING FUNCTION
The present invention relates to a gardening tool and, more particularly, to a pair of gardening shears with an energy-saving ifinction.
A pair of conventional gardening shears in accordance with the prior art shown in FIG 6 comprise a main cutter 40, a secondary cutter 50, and an energy-saving arm 60. The main cutter 40 is connected pivotally with the secondary cutter 50. The main cutter 40 has a first end formed with a blade portion 4! and a second end formed with an elongate hole 42. The secondary cutter 50 has a first end formed with a blade portion 51 and a second end formed with a handle 52. The energy-saving arm 60 has a first end pivotally connected with the secondary cutter 50 and a second end formed with a handle 61. The energy-saving arm 60 has a face formed with a limit slot 62. The limit slot 62 of the energy-saving arm 60 is connected with the elongate hole 42 of the main cutter 40 by a shaft 63. The limit slot 62 of the energy-saving arm 60 has a side formed with a first opening 621, a second opening 622 and a third opening 623. The shaft 63 is detachably locked in the first opening 621, the second opening 622 or the third opening 623 of the limit slot 62.
In opera.tion, when the handle 61 of the energy-saving arm 60 and the handle 52 of the secondary cutter 50 are moved toward each other, the energy-saving arm 60 is moved toward the secondary cutter 50, and the limit slot 62 of the energy-saving arm 60 presses and drives the shaft 63 which pushes and drives the elongate hole 42 of the main cutter 40 so that the main cutter 40 is pivoted relative to the secondary cutter 50, and the blade portion 41 of the main cutter 40 is moved toward the blade portion 51 of the secondary cutter 50 to perform a shearing action. The shaft 63 changes the relative position of the limit slot 62 of the energy-saving aim 60 and the elongate hole 42 of the main cutter 40 during the shearing process so that the shaft 63 is in turn inserted through the first opening 621 into the second opening 622 and the third opening 623 of the limit slot 62 to change and limit the closed angle between the blade portion 41 of the main cutter 40 and the blade portion SI of the secondary cutter 50 step by step so that the user can apply a force on the energy-saving arm 60 in a stepwise manner, thereby achieving an energy-saving effect. The energy-saving arm 60 has its first end pivotally connected with the secondary cutter 50, and the limit slot 62 of the energy-saving arm 60 drives the shaft 63 to proceed a leverage action so as to produce an energy-saving effect to the main cutter 40.
However, the shaft 63 is moved along the elongate hole 42 of the main cutter 40 toward the blade portion 41 of the main cutter 40 during the shearing process to reduce the force applied by the shaft 63 on the main cutter 40. thereby decreasing the energy-saving effect to the main cutter 40. In addition, when the limit slot 62 of the energy-saving arm 60 presses the shaft 63 to push the elongate hole 42 of the main cutter 40, the limit slot 62 of the energy-saving arm 60 and the elongate hole 42 of the main cutter 40 exert two opposite forces to clamp the shaft 63, so that when the shaft 63 slides between the limit slot 62 of the energy-saving arm 60 and the elongate hole 42 of the main cutter 40, the shaft 63 is subjected to a larger resistance by the limit slot 62 of the energy-saving arm 60 and the elongate hole 42 of the main cutter 40.
Further, the conventional gardening shears do not have a limit ffinction so that the blade portion 41 of the main cutter 40 and the blade portion 51 of the secondary cutter 50 are easily opened or closed freely, thereby causing danger to the user.
According to the primary advantage of the present invention, when the first handle of the main cutter and the second handle of the energy-saving arm are driven to move toward each other, the energy-saving arm drives the gear which drives the secondary cutter, so that the first blade portion of the main cutter and the second blade portion of the secondary cutter are moved toward each other to shear the object, and the gear is driven to press the toothed portion of the sliding slot and is moved in the sliding slot of the secondary cutter to reach the outermost position of the sliding slot so as to achieve an energy-saving effect by a leverage principle.
According to another advantage of the present invention, the gear is rotatably mounted on the energy-saving arm and meshes with the toothed portion of the sliding slot so that the gear is rotated smoothly and exactly to aid the shearing action of the main cutter and the secondary cutter during the shearing process so as to reduce the shearing resistance of the main cutter and the secondary cutter.
According to a further advantage of the present invention, the gear meshes with the toothed portion of the sliding slot to limit the main cutter and the secondary cutter so that the first blade portion of the main cutter and the second blade portion of the secondary cutter are limited and will not be opened or closed freely, thereby preventing from the user from being hurt by the first blade portion of the main cutter and the second blade portion of the secondary cutter due to a free movement.
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.

FIG. 2 is an exploded perspective view of the gardening shears as shown in FIG. I. FIG. 3 is a front view of the gardening shears as shown in FIG. I. FIG. 4 is a schematic operational view of the gardening shears as shown in FIG 3.
FIG. 5 is a perspective operational view of a pair of gardening shears in accordance with another preferred embodiment of the present invention.
FIG. 6 is a front view of a pair of conventional gardening shears in
accordance with the prior art.
Referring to the drawings and initially to FIGS. 1-4, a pair of gardening shears in accordance with the preferred embodiment of tile present invention comprise a main cutter 10, a secondary cutter 20 pivotally connected with the main cutter 10, an energy-saving arm 30 pivotally connected with the secondary cutter 20, and a gear 31 pivotally connected with the energy-saving arm 30.
The main cutter 10 has a first end formed with a first blade portion 12 and a second end formed with a first handle 13. The main cutter 10 has a mediate portion formed with a first connecting hole 11 located between the first blade portion 12 and the first handle 13 and a first pivot hole 14 located between the first connecting hole 11 and the first handle 13.
The secondary cutter 20 has a first end formed with a second blade portion 22 and a second end formed with a sliding slot 23. In the preferred embodiment of the present invention, the first blade portion 12 of the main cutter 10 and the second blade portion 22 of the secondary cutter 20 are a combination of a blade and an anvil. The sliding slot 23 of the secondary cutter has an elongate shape and has a side formed with a toothed portion 231. The secondary cutter 20 has a mediate portion formed with a second connecting hole 21 located between the second blade portion 22 and the sliding slot 23.
The second connecting hole 21 of the secondary cutter 20 and the first connecting hole II of the main cutter 10 construct a first pivot point "A".
The first pivot point "A" is formed by a threaded shaft 15 and a nut 16 so that the second connecting hole 2 1 of the secondary cutter 20 and the first connecting hole 11 of the main cutter 10 are connected pivotally by the threaded shaft 15 and the nut 16. The first connecting hole 1! of the main cutter is a non-circular hole. The threaded shaft 15 has a surface formed with a flattened face 15 1 secured in the first connecting hole 11 of the main cutter 10 so that the main cutter 10, the threaded shaft 15 and the nut 16 are connected fixedly to prevent the nut 16 from being loosened from the threaded shaft 15.
The energy-saving arm 30 has a first end formed with a second pivot hole 32 and a second end formed with a second handle 33. The second pivot hole 32 of the energy-saving arm 30 and the first pivot hole 14 of the main cutter 10 construct a second pivot point "B". The energy-saving ann 30 consists of two plates 30A and 30B which are combined together by bolts 34 and nuts 35. The two plates 30A and 30B of the energy-saving arm 30 are located at two opposite sides of the sliding slot 23 of the secondary cutter 20.
The gear 31 is located between the second pivot hole 32 and the second handle 33 of the energy-saving arm 30. The gear 31 is rotatably mounted on a mediate portion of the energy-saving arm 30. The gear 31 is received in the sliding slot 23 of the secondary cutter 20 and meshes with the toothed portion 231 of the sliding slot 23. The gear 31 is sandwiched between the two plates 30A and 30B of the energy-saving arm 30 so that the gear 31 is fully limited in the sliding slot 23 of the secondary cutter 20.
The distance between the first pivot point "A" and the second pivot point "B" is smaller than that between the first pivot point "A" and the gear 3 1.
When the first blade portion 12 of the main cutter 10 and the second blade portion 22 of the secondaiy cutter 20 are disposed at an open state as shown in FIG. 4, the distance between the first pivot point "A" and the gear 31 is smaller than that between the second pivot point "B" and the gear 3 1. On the contrary, when the first blade portion 12 of the main cutter 10 and the second blade portion 22 of the secondary cutter 20 are disposed at a closed state as shown in FIG 3, the distance between the first pivot point "A" and the gear 31 is greater than that between the second pivot point "B" and the gear 3 I. Thus, the second handle 33 of the energy-saving arm 30 fimctions as a force applying point, and the second pivot point "B" functions as a fttlcrum so that the gear 3 I is driven to press the toothed portion 231 of the sliding slot 23 by a leverage principle to achieve an energy-saving effect.
The gardening shears further comprise a spacer 36 mounted between the second pivot hole 32 of the energy-saving arm 30 and the first pivot hole 14 of the main cutter 10 to limit the fitting position of the main cutter 10. The secondary cutter 20 has a side formed with a limit hole 24 located between the second connecting hole 21 and the sliding slot 23. Thus, when the first blade portion 12 of the main cutter 10 and the second blade portion 22 of the secondary cutter 20 are disposed at the closed state as shown in FIG. 3, the spacer 36 abuts the limit hole 24 of the secondary cutter 20 to prevent the gear 31 from hitting the sliding slot 23 of tile secondary cutter 20 due to a closing action of the first blade portion 12 of the main cutter 10 and the second blade portion 22 of the secondary cutter 20.
In assembly, the second connecting hole 21 of the secondary cutter 20 and the first connecting hole 11 of the main cutter 10 are connected by the threaded shaft 15 and the nut 16 so that tile secondary cutter 20 and the main cutter 10 are connected pivotally by the threaded shaft I 5 aiid the nut I 6. At this time, the second connecting hole 21 of the secondary cutter 20 and the first connecting hole 11 of the main cutter 10 construct the first pivot point "A".
Then, the two plates 30A and 30B oftlie energy-saving arm 30 are juxtaposed to each other, with the secondary cutter 20 being disposed between the two plates 30A and 30B of the energy-saving arm 30, and with the gear 31 being received and limited in the sliding slot 23 of the secondary cutter 20. In such a manner, the gear 31 meshes with the toothed portion 231 of the sliding slot 23.
Then, the two plates 30A and 30B of the energy-saving arm 30 are combined together by the bolts 34 and the nuts 35. At this time, one of the bolts 34 is extended through the second pivot hole 32 of the energy-saving arm 30, the spacer 36 and the first pivot hole 14 of the main cutter 10 so that the second pivot hole 32 of the energy-saving arm 30 and the first pivot hole 14 of the main cutter 10 are connected pivotally, and the spacer 36 is clamped between the second pivot hole 32 of the energy-saving arm 30 and the first pivot hole 14 of the main cutter 10. In such a manner, the second pivot hole 32 of the energy-saving arm 30 and the first pivot hole 14 of the main cutter 10 construct the second pivot point "B". In addition, the other one of the bolts 34 is extended through the energy-saving arm 30, the sliding slot 23 of the secondary cutter 20 and the gear 31.
In operation, referring to FIGS. 3 and 4 with reference to FIGS. 1 and 2, the main cutter 10 is connected pivotally with the secondary cutter 20 and the energy-saving ann 30 to form the first pivot point "A", while the gear 3 I meshes with the toothed portion 23 I of the sliding slot 23 to connect the secondary cutter 20 and the energy-saving arm 30 so that the secondary cutter 20 is connected pivotally with the energy-saving arm 30 to form and the second pivot point "B". At this time, the distance between the first pivot point "A" and the second pivot point "B" is smaller than that between the first pivot point "A" and the gear 31.
As shown in FIG 4, when the first blade portion 12 of the main cutter 10 and the second blade portion 22 of the secondary cutter 20 are disposed at the open state, the first blade portion 12 of the main cutter 10 co-operates with the second blade portion 22 of the secondary cutter 20 to clamp an object, such a.s a branch or the like. At this time, the distance between the first pivot point "A" and the gear 3 1 is smaller than that between the second pivot point "B" and the gear 31. In addition, the second pivot point "B" functions as a fulcrum of the energy-saving arm 30, and the first pivot point "A" functions as a fulcrum of the secondary cutter 20. In such a manner, when the first handle 13 of the main cutter 10 and the second handle 33 of the energy-saving arm 30 are subjected to a force and are moved toward each other, the energy-saving arm drives the gear 3 I which drives the secondary cutter 20 relative to the main cutter 10, so that the first blade portion 12 of the main cutter 10 and the second blade portion 22 of the secondary cutter 20 are moved toward each other to shear the object. At this time, when the gear 31 is driven by the energy-saving arm 30, the gear 31 presses the toothed portion 231 of the sliding slot 23 and is moved in the sliding slot 23 of the secondary cutter 20 to reach the outermost position of the sliding slot 23 so as to achieve an energy-saving effect by a leverage principle.
As shown in FIG 3, when the first blade portion 12 of the main cutter and the second blade portion 22 of the secondary cutter 20 are disposed at the closed state, the distance between the first pivot point "A" and the gear 31 is greater than that between the second pivot point "B" and the gear 31. At this Is time, the spacer 36 abuts the limit hole 24 of the secondary cutter 20 to prevent the gear 3 I from hitting the sliding slot 23 of the secondary cutter 20 due to the closing action of the first blade portion 12 of the main cutter 10 and the second blade portion 22 of the secondary cutter 20.
Referring to FIG S with reference to FIGS. 1 and 2, each of the first handle 13 of the main cutter 10 and the second handle 33 of the energy-saving arm 30 is extended to increase the length of the force arm so as to enhance the leverage action and to increase the energy-saving effect.
Accordingly, when the first handle 13 of the main cutter 10 and the second handle 33 of the energy-saving arm 30 are driven to move toward each other, the energy-saving arm 30 drives the gear 3 I which drives the secondary cutter 20, so that the first blade portion 12 of the main cutter 10 and the second blade portion 22 of the secondary cutter 20 are moved toward each other to shear the object, and the gear 31 is driven to press the toothed portion 231 of the sliding slot 23 and is moved in the sliding slot 23 of the secondary cutter 20 to reach the outermost position of the sliding slot 23 so as to achieve an energy-saving effect by a leverage principle. In addition, the gear 31 is rotatably mounted on the energy-saving arm 30 and meshes with the toothed portion 231 of the sliding slot 23 so that the gear 31 is rotated smoothly and exactly to aid the shearing action of the main cutter 10 and the secondary cutter during the shearing process so as to reduce the shearing resistance of the main cutter 10 and the secondary cutter 20. Further, the gear 31 meshes with the toothed portion 231 of the sliding slot 23 to limit the main cutter 10 and the secondary cutter 20 so that the first blade portion 12 of the main cutter 10 and the second blade portion 22 of the secondary cutter 20 are limited and will not be opened or closed freely, thereby preventing from the user from being hurt by the first blade portion 12 of the main cutter 10 and the second blade portion 22 of the secondary cutter 20 due to a free movement.
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.
