Description

Pruning tool

Technical field

The present invention relates to a kind of pruning tools, more particularly, to the pulling component of cutting implement, for cutting assembly Regulating device and handle.

Background technology

The tool of the well known hand-bill such as with telescopic rod in this field, hedge clipper, shrub and hedge trimmer.These tools usually wrap It includes：Assembly is sheared, there is at least one movable part in shearing assembly；Telescopic rod is attached to shearing assembly；With driving line Cable has the first end for being attached to shearing assembly and is attached to the second end for pulling component.Component is pulled to be configured to shearing Assembly transmits pulling force.This tool can be used for shearing the branch in open area, and the space of open area is unrestricted.

However, for user, the above-mentioned tool with bar (for example, telescopic rod) uses very in narrow space It is uncomfortable, and due to no handle, can not just be operated in the case of no bar.Further, these tools, which do not have, adjusts The regulating device of the width of the shearing jaw of section shearing assembly.Therefore, no matter branch is smaller or larger, during shearing manipulation, The constant width of the shearing jaw of these tools.In addition, these tools do not have the storing unit for pulling component, therefore draw Dynamic component can freely be suspended in one end, this is likely to result in trouble during storage, transport and during shearing manipulation.

Therefore, in view of the above, a kind of improved tool is needed.

Invention content

In view of the above, present invention aim to address or at least reduce problems discussed above.In the reality of the present invention It applies in mode, which realizes at least partially by the pruning tool with handle.Pruning tool includes：Shear assembly, tool It includes at least one movable part to have blade apparatus, blade apparatus；With driving cable, it is attached at the first end of driving cable To at least one movable part, wherein driving cable is configured to activate at least one movable part.Pruning tool into One step includes being coupled to the middle section of shearing assembly, and be arranged to the handle adjacent with middle section.Handle construction is at for making User grasps during operating pruning tool.The length range of handle is about 10cm to 30cm.Channel is formed in handle, wherein The second end of driving cable is received by channel.

According to embodiment, the length of the handle of pruning tool is about 15cm.

According to embodiment, middle section is integrally formed with handle.

According to embodiment, shearing assembly includes fixed blade and at least one movable part.This is at least one removable Dynamic component is removable blade.Removable blade is pivotally connected to fixed blade, is wherein formed with middle part in fixed blade Point.

According to embodiment, fixed blade and removable blade form cutting for the longitudinal axis offset orientation relative to handle Cutting nipper mouth.

Decreased food is shorter, this can be convenient for shearing branch in narrow space, in narrow space, repairing with telescopic rod The tool of cutting will be difficult to carry out shear action.Channel can provide support and protection for driving cable, while allow to drive cable connection To removable blade.Since driving cable is bypassed by channel, driving cable can will not be shifted and is wrapped on branch.It is logical Road additionally provides improved ergonomic designs, in which during operation drives cable near the hand that user is used for gripping Entering tool.Preferably, the horn-like shape of second opening in channel is permissible pulls the of driving cable in different directions Two ends.

According to embodiment, pruning tool includes the regulating device for being configured to adjust the maximum width of shearing jaw.

According to embodiment, regulating device includes the cam member for the pivoting action for being configured to limitation removable blade.Root According to another embodiment, regulating device includes the brake for the pivoting action for being configured to limitation removable blade.Shear jaw Regulating device can optimize the range for pulling driving cable.When shearing twig, regulating device can limit the range of shearing jaw, Therefore removable blade need to be moved shorter distance to shear, this makes the range that need to pull driving cable reduce.Cause This, can be improved the ergonomics of pruning tool.

According to embodiment, pruning tool further comprises the pulling component for being attached to the second end of driving cable.

According to embodiment, pruning tool has the first pontes for being formed as neighbouring middle section.Pull component packet Include the second connecting portion point for being configured to be detachably coupled to the first pontes.

According to embodiment, the first pontes of handle includes chamber, and the second connecting portion of component is pulled to be divided into elongation Part.The chamber of handle is configured at least partly and removably receives the elongated portion for pulling component.

According to embodiment, pruning tool further comprises the bar for being attached to handle.

When using the pruning tool for not having bar, pruning tool is provided for storing the device for pulling component.Trimming Tool also stores the device for pulling component using bar by being mounted on pulling on member slide to provide on bar.

According to embodiment, handle includes the grip portion for being configured to grasp for user.The neighbouring shearing assembly in wide portion.Into One step, the width in wide portion is more than the width of grip portion.

According to embodiment, it includes the retained part for having T-shape to pull component.According to another embodiment, pull Component includes the retained part for having D-shape.

According to embodiment, component is pulled to further comprise driving cable winding device.According to another embodiment, pull Component includes driving cable expanding unit.

According to aspects of the present invention, the fixed blade in assembly is sheared to may be designed to guide branch towards shear blade.Fixing cutter The flexible hand to avoid user in distal end of piece is slided towards shear blade.Due to offset distance, between pivotal point and tie point Distance also increases.It is possible to increase the torque of the pulling force on removable blade.If the width in the wide portion of handle first end is larger The hand for helping avoid user is slided towards shearing assembly.Therefore, which can improve the ergonomics of tool and avoid pair User causes any harm.D-shaped or T shapes pull component that can improve clamping while avoiding sliding, this is applied increase For shearing the pulling force of branch.Driving cable winding device can ensure that wind additional driving cable and avoids during operation Winding.Driving cable expanding unit can ensure that smoothly removes driving cable from driving cable winding device.Therefore, it can improve and repair Cut the ergonomics of tool.
