The present invention relates to a gardening shear and more particularly to a labor-saving gardening shear.
Generally, a conventional gardening shear comprises a pair of blades to cut and trim parts of plant which include limbs, branches and twigs.
However, the conventional gardening shear is disadvantageous because: some limbs or branches are thick that a user needs to take great strength to operate the gardening shear; and (ii) although there are some labor-saving gardening shears in the market, the structures thereof are always complicated, which leads to more costs and effort for manufacture. Therefore, there remains a need for a new and improved design for a gardening shear to overcome the problems presented above.
The present invention provides a gardening shear which comprises a first blade, a second blade, a first handle, and a second handle. The first blade has a first cutting portion, and a first through hole and a second through hole respectively penetrate a middle portion and a lower portion of the first blade. The second through hole is located adjacent to one lateral side of the lower portion of the first blade, and a pivot portion laterally protruding from the other lateral side of the lower portion of the first blade has a third through hole thereon. Moreover, the pivot portion and the first cutting portion are positioned at the same lateral side of the first blade. The second blade comprises a second cutting portion, and a fourth through hole penetrating through a middle portion of the second blade is located at a position corresponding to the first through hole of the first blade. When the first blade and the second blade are coupled together, the first through hole and the fourth through hole are adapted to be aligned to enable a pivot member to pass therethrough so as to pivotally connect the first blade with the second blade. Furthermore, a protruding edge protruding from an edge of the middle portion of the second blade is located adjacent to the fourth through hole, and a fifth through hole penetrates through the protruding edge. Additionally, a lower portion of the second blade has an arm, and a sixth through hole penetrating through the arm is located adjacent to a lower edge of the second blade. The first handle is a long pole, and an upper portion thereof has a first connecting section. Also, a seventh through hole and a first elongated hole respectively penetrate through the first connecting section. The seventh through hole and the first elongated hole are configured to respectively be aligned with the second through hole of the first blade and the sixth through hole of the second blade, and a connecting member is adapted to penetrate through the seventh through hole and the second through hole while another pivot member is configured to penetrate through the first elongated hole and the sixth through hole to pivotally connect the first handle with the first blade and the second blade. In addition, a first rolling member is disposed on the pivot member which penetrates through the first elongated hole, and the first rolling member is configured to roll and shift along the first elongated hole so as to enable the first handle to drive and open/close the first blade and the second blade. Similarly, the second handle is a long pole, and an upper portion thereof has a second connecting section. Also, an eighth through hole and a second elongated hole respectively penetrate through the second connecting section. The eighth through hole and the second elongated hole are configured to respectively aligned with the fifth through hole of the second blade and the third through hole of the first blade, and another connecting member is adapted to penetrate through the eighth through hole and the fifth through hole while a third pivot member is configured to penetrate through the second elongated hole and the third through hole to pivotally connect the second handle with the first blade and the second blade. Additionally, a second rolling member is disposed on the pivot member which penetrates through the second elongated hole, and the second rolling member is configured to roll and shift along the second elongated hole so as to enable the second handle to drive and open/close the first blade and the second blade.
Comparing with conventional gardening shear, the present invention is advantageous because: (i) by using leverage principle, a user can use the gardening shear of the present invention to easily cut limbs or branches of plant, which is labor-saving; and (ii) the gardening shear of the present invention is simple in structure, which saves time and effort in assembly and lowers costs of manufacture.

In order to further understand the goal, characteristics and effect of the present invention, a number of embodiments along with the drawings are illustrated as following:
Referring to
In one embodiment, the first cutting portion (11) is a cutting edge, and the second cutting portion (21) is a blade anvil.
In another embodiment, the second cutting portion (21) and the arm (25) are extended obliquely from the middle portion of the second blade (20) toward two opposite directions.
In still another embodiment, the second blade (20) has a protruding portion (27) at a position corresponding to the sixth through hole (26), and the protruding portion (27) is configured to separate a distance between the lower portion of the second blade (20) and the first connecting section (301).
In a further embodiment, the first connecting section (301) is a flat plate body which is extended from an upper end of the first handle (30), and the first connecting section (301) has two consecutive bending sections to horizontally shift a portion of the first connecting section (301) above the bending sections to a side of the first handle (30).
In still a further embodiment, the second connecting section (401) is a flat plate body which is extended from an upper end of the second handle (40).
In a particular embodiment, each of the pivot members (50) is a bolt cooperating with a nut.
In a preferred embodiment, the connecting member (60) is a bolt and the second through hole (13) is a screw hole such that the connecting member (60) is configured to pass through the seventh through hole (302) to engage with the second through hole (13).
In another preferred embodiment, the connecting member (60) is a bolt and the eighth through hole (402) is a screw hole such that the connecting member (60) is configured to pass through the fifth through hole (24) to engage with the eighth through hole (402).
