Each of the two cutters 10 has a first end provided with a driven portion 13, a second end provided with a cutting portion 12 and a middle portion provided with a first pivot hole 11 located between the driven portion 13 and the cutting portion 12. The two cutters 10 are pivotally connected at the first pivot hole 11 thereof. The cutting portions 12 of the two cutters 10 may have different shapes and forms, and the first pivot holes 11 of the two cutters 10 may have different shapes. Preferably, the cutting portion 12 of each of the two cutters 10 is a blade or an anvil. The driven portion 13 of each of the two cutters 10 has a surface provided with an elongate sliding slot 131. Each of the two cutters 10 has a side provided with a first opening 14 and a second opening each located between the first pivot hole 11 and the sliding slot 131. The first opening 14 and the second opening 15 of each of the two cutters 10 are located at an inner side of the driven portion 13 so that the first openings 14 and the second openings 15 of the two cutters 10 face each other respectively. The first opening 14 of each of the two cutters 10 is located between the first pivot hole 11 and the second opening 15 and has a size smaller than that of the second opening 15.
Each of the two driving arms 20 has a first end provided with a second pivot hole 21, a second end provided with a drive portion 22 and a mediate section provided with a connecting portion 23 located between the second pivot hole 21 and the a drive portion 22. The two driving arms 20 are pivotally connected at the second pivot hole 21 thereof. Each of the two driving arms 20 has a side provided with a first pressing flange 24 that is extendable into the first opening 14 of a respective one of the two cutters 10 and a second pressing flange 25 that is extendable into the second opening 15 of a respective one of the two cutters 10. The first pressing flange 24 and the second pressing flange 25 of each of the two driving arms 20 is located beside the second pivot hole 21.
The connecting portion 23 of each of the two driving arms 20 has a surface provided with a connecting hole 231 aligning with the sliding slot 131 of a respective one of the two cutters 10, and the gardening shears further comprise two limit members 26 each extending through the connecting hole 231 of a respective one of the two driving arms 20 and the sliding slot 131 of a respective one of the two cutters 10 so that the connecting portion 23 of each of the two driving arms 20 is pivotally connected with the driven portion 13 of a respective one of the two cutters 10. Each of the two limit members 26 is a fastening bolt which is slidable in the sliding slot 131 of the respective cutter 10, and the gardening shears further comprise two fastening nuts 27 each screwed onto a respective one of the two limit members 26, and two bushings 28 each mounted on a respective one of the two limit members 26 and each slidable in the sliding slot 131 of the respective cutter 10.
Each of the two support plates 16 has a first end provided with a first through hole 161 aligning with the first pivot hole 11 of a respective one of the two cutters 10 and a second end provided with a second through hole 162 aligning with the second pivot hole 21 of a respective one of the two driving arms 20, and the gardening shears further comprise a first pivot bolt hA extending through the first through hole 161 of each of the two support plates 16 and the first pivot hole 11 of each of the two cutters 10, a first locking nut 11B screwed onto the first pivot bolt hA, a second pivot bolt 21A extending through the second through hole 162 of each of the two support plates 16 and the second pivot hole 21 of each of the two driving arms 20, and a second locking nut 21B screwed onto the second pivot bolt 21A. Thus, the two cutters are limited between the two support plates 16 by the first pivot bolt 11 A and the first locking nut 11B, and the two driving arms 20 are limited between the two support plates 16 by the second pivot bolt 21 A and the second locking nut 21B.
In operation, referring to Figs. 4-6 with reference to Figs. 1-3, the two cutters 10 are pivoted about the first pivot hole 11, and the two driving arms 20 are pivoted about the second pivot hole 21 so that the two cutters 10 and the two driving arms 20 have two different pivot fulcrums (the first pivot hole 11 and the second pivot hole 21). In addition, each of the two limit members 26 is slidable in the sliding slot 13 1 of the respective cutter 10 so that the connecting portion 23 of each of the two driving arms 20 is pivotally and movably connected with the driven portion 13 of the respective cutter 10. In such a manner, when the two driving arms 20 are moved by an external force, the two driving arms 20 are pivoted about the second pivot hole 21, and the connecting portion 23 of each of the two driving arms 20 is driven to move the respective limit member 26 which moves the driven portion 13 of the respective cutter 10 so that the two cutters 10 are driven and pivoted about the first pivot hole 11, and the cutting portions 12 of the two cutters 10 are moved relative to each other. At this time, the first pressing flange 24 of each of the two driving arms 20 can be moved toward and extended into the first opening 14 of the respective cutter 10, and the second pressing flange 25 of each of the two driving arms 20 can be moved toward and extended into the second opening 15 of the respective cutter 10.
Thus, when the two driving arms 20 are moved and pivoted outward relative each other, the two cutters 10 are moved and pivoted relative to each other from the closed position as shown in Figs. 1 and 6 to the opened position as shown in Fig. 4, so that the cutting portions 12 of the two cutters 10 are moved outward relative to each other. On the contrary, when the two driving arms 20 are moved and pivoted toward each other, the two cutters 10 are moved and pivoted relative to each other from the opened position as shown in Fig. 4 to the closed position as shown in Figs. 1 and 6, so that the cutting portions 12 of the two cutters 10 are moved toward each other to perform a cutting or shearing action so as to cut or prune a plant and the like.
As shown in Fig. 4, when the two cutters 10 are moved to the opened position, the cutting portions 12 of the two cutters 10 are moved to space from each other, each of the two limit members 26 is moved to abut the uppermost limit of the sliding slot 131 of the respective cutter 10 and is proximate to the first pivot hole 11, and the first pressing flange 24 of each of the two driving arms 20 is moved and extended into the first opening 14 of the respective cutter 10.
As shown in Fig. 5, when the two cutters 10 are moved from the opened position toward the closed position, the cutting portions 12 of the two cutters 10 are moved toward each other, each of the two limit members 26 is moved in the sliding slot 131 of the respective cutter 10 and is moved from the uppermost limit of the sliding slot 131 of the respective cutter 10 toward the lowermost limit of the sliding slot 131 of the respective cutter 10, and the first pressing flange 24 of each of the two driving arms 20 is rotated in a curved manner to push the first opening 14 of the respective cutter 10 so as to move the respective cutter 10.
As shown in Fig. 6, when the two cutters 10 are moved to the closed position, the cutting portions 12 of the two cutters 10 are moved to abut each other, each of the two limit members 26 is moved to abut the lowermost limit of the sliding slot 131 of the respective cutter 10 and is distal to the first pivot hole 11, the first pressing flange 24 of each of the two driving arms 20 is moved to detach from the first opening 14 of the respective cutter 10, and the second pressing flange 25 of each of the two driving arms 20 is moved and extended into the second opening 15 of the respective cutter 10.
As shown in Figs. 1-6, the cutting portion 12 of one of the two cutters is a blade, and the cutting portion 12 of the other one of the two cutters 10 is an anvil so that the cutting portions 12 of the two cutters 10 can be used to cut branches.
As shown in Fig. 7, the cutting portion 12 of each of the two cutters is an elongate blade so that the cutting portions 12 of the two cutters 10 can be used to shear flowers and grass.
Accordingly, the two driving arms 20 co-operate with the two cutters to perform a shearing action so that the gardening shears have a longer force arm to facilitate a user operating the gardening shears in an energy-saving manner. In addition, the first pressing flange 24 of each of the two driving arms pushes the first opening 14 of the respective cutter 10 to move the respective cutter 10 so that the first pressing flanges 24 of the two driving arms provide an assistant force to move the two cutters 10, thereby enhancing the shearing effect of the two cutters 10. Further, the two cutters 10 are pivoted about the first pivot hole 11, and the two driving arms 20 are pivoted about the second pivot hole 21 so that the two cutters 10 and the two driving arms 20 have two different pivot fulcrums to distribute the shearing force evenly and smoothly so as to prevent from producing a stress concentration at the two pivot fulcrums. Further, the two cutters 10 and the two driving arms 20 are sandwiched between and limited by the two support plates 16 so that the two cutters 10 and the two driving arms 20 are operated and moved solidly and stably.
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.
