Abstract

The present invention provides a power-driven hedge trimmer with a movable front handle. The power-driven hedge trimmer includes: a power and trimming assembly, a gripping assembly and a control unit. The power and trimming assembly includes a trimming blade and a power source. The trimming blade is connected to the power source so as to be driven to reciprocate. The gripping assembly includes a front gripping portion, a connecting portion and a rear gripping portion. The control unit is disposed on the connecting portion for controlling the power source. The front gripping portion includes a suspended front arm, a front handle and a front stop lock. The front handle is lockable at two locking positions, which are located on two opposite sides of the suspended front arm, with the front stop lock.

Claims

1. A power-driven hedge trimmer, comprising:

a power and trimming assembly comprising a trimming blade and a power source, wherein the trimming blade is connected to the power source so as to be driven to reciprocate;

a gripping assembly comprising a front gripping portion, a connecting portion and a rear gripping portion, wherein the front gripping portion is attached to a first side of the power source via a front attaching portion, the rear gripping portion is attached to a second side of the power source opposite to the first side thereof via a rear attaching portion, and the connecting portion is connected with the rear attaching portion, the front gripping portion and the rear gripping portion simultaneously; and

a control unit disposed on the connecting portion for controlling the power source;

wherein the front gripping portion includes a suspended front arm, a front handle and a front stop lock, the front attaching portion and the connecting portion are connected to two ends of the suspended front arm respectively, the front stop lock is disposed on the suspended front arm, and an end of the front handle is pivotally connected to a front end of the suspended front arm;

wherein the front handle is lockable in at least two locking positions, which are located on two opposite sides of the suspended front arm, with the front stop lock,

wherein an end of the front handle is pivotally connected to a front end of the suspended front arm, so the front handle can be rotated with respect to the suspended front arm, and a front stop lock is disposed on the suspended front arm at a location near the pivotal connection of the front handle for locking the front handle, and

wherein the rotational axis of the front handle is perpendicular to the longitudinal direction of the trimming blade, the front handle rotating horizontally around the rotational axis between a first position and a second position at the two sides of the suspended front arm, the first position and the second position forming a 180 degree angle.

2. The power-driven hedge trimmer according to claim 1, wherein the front handle is positioned at a 90°

angle relative to the suspended front arm, and the front handle is moveable within a range in each of the two locking positions.

3. The power-driven hedge trimmer according to claim 1, wherein the rear gripping portion comprises a rear handle, and an end of the rear handle is connected to the connecting portion.

4. The power-driven hedge trimmer according to claim 3, wherein a contacting area between the suspended front arm and the connecting portion is equal to a cross-sectional area of the rear handle.

5. The power-driven hedge trimmer according to claim 1, wherein the suspended front arm extends from the connecting portion at a 90°

-120°

angle.

6. A power-driven hedge trimmer, comprising:

a power and trimming assembly comprising a trimming blade and a power source, wherein the trimming blade is connected to the power source so as to be driven to reciprocate;

a gripping assembly comprising a front gripping portion, a connecting portion and a rear gripping portion, wherein the front gripping portion is attached to a first side of the power source via a front attaching portion, the rear gripping portion is attached to a second side of the power source opposite to the first side thereof via a rear attaching portion, and the connecting portion is connected with the rear attaching portion, the front gripping portion and the rear gripping portion simultaneously; and

a control unit disposed on the connecting portion for controlling the power source;

wherein the front gripping portion includes a suspended front arm, a front handle and a front stop lock, the front attaching portion and the connecting portion are connected to two ends of the suspended front arm respectively, the front stop lock is disposed on the suspended front arm, and an end of the front handle is pivotally connected to a front end of the suspended front arm;

wherein the front handle can be locked in at least two locking positions, which are located on two opposite sides of the suspended front arm, with the front stop lock,

wherein both the front attaching portion and the rear attaching portion are rotary shafts, and a rotation axis of the front attaching portion on the first side of the power source is aligned with a rotation axis of the rear attaching portion on the second side of the power source.

7. The power-driven hedge trimmer according to claim 6, wherein a rear stop lock is disposed on the rear gripping portion for locking the front attaching portion and the rear attaching portion at fixed locations.
