A handheld portable cutting apparatus has a cutter unit with a cutter unit longitudinal axis. In a central housing section of the cutting apparatus, a drive connection is arranged between an electric drive motor and the cutter unit, wherein a motor housing having a motor housing longitudinal axis extends from the central housing section. A handle extends from the central housing section in a handle longitudinal axis. The cutter unit includes a guide bar with a saw chain circulating thereon, wherein, in a side view onto the cutting apparatus, the point of intersection between the handle longitudinal axis and the motor housing longitudinal axis and also the point of intersection between the handle longitudinal axis and the cutter unit longitudinal axis lie in the central housing section.
Chain saw
A chain saw includes a housing, the housing including a first housing, a second housing, and a receiving cavity formed by the first housing and the second housing; a cutter including a blade chain and a blade bar for supporting the blade chain, the cutter being mounted on the housing; a power assembly, the power assembly including a drive unit for driving the cutter and a power supply unit for supplying power to the drive unit; a front handle connected to the second housing and surrounding the first housing, the front handle including a grip portion, a first and second fixing parts which are located at two ends of the grip portion, the first fixing part abutting on the side wall of the second housing, and the second fixing part being located at the bottom of the housing and connecting with the second housing.
Tree limb or trunk cutting device
A tree limb or trunk cutter including a saw assembly, a clamp, and a remote controller. The saw assembly includes a housing, at least one motor disposed within the housing, and a saw bar support rotatably coupled to the housing. The motor is operatively coupled to the saw bar support and configured to rotate the saw bar support about an axis in a first direction and a second direction opposite the first direction. A wireless receiver coupled to the housing is operable to receive commands from a remote controller. The clamp is configured to secure to a limb or trunk of a tree. The housing releasably couples to the clamp. The remote controller is in communication with the wireless receiver and is configured to control a direction of rotation of the saw bar support and to control power provided to a chain drive.
Driving Apparatus
A handheld driving apparatus is provided for mowing or cutting an object. The driving apparatus comprises: a container, a lock member, a trigger lever, and an action unit. The container is configured to extend from a rear side where a user is located toward a front side where the object is located. The lock member is configured to move between a first position and a second position, a straight line connecting the first position and the second position extending in a direction in which the container extends or in a direction orthogonal to a direction in which the container extends. The trigger lever is configured to move between a third position and a fourth position, to be restricted from moving to the fourth position when the lock member is at the first position, and not to be restricted from moving to the fourth position when the lock member is at the second position. The action unit is provided on the front side of the container, and is configured to drive in such a manner that a mechanical action for mowing or cutting the object can be applied to the object when the trigger lever is at the fourth position.
CHAIN SAW AND METHOD FOR OPERATING A CHAIN SAW
The disclosure relates to a chain saw having a housing and a drive motor. The drive motor by way of a chain drive sprocket drives a saw chain guided on a guide bar. The guide bar is held on the housing by way of a releasable fastening arrangement and by way of a tensioning device is displaceable in the direction of the longitudinal axis of the guide bar in relation to the housing while the fastening arrangement is released. The saw chain has a slack side between the chain drive sprocket and the guide bar. The chain saw includes a chain lifting device which is configured separately from the tensioning device. The chain lifting device is configured for deflecting the saw chain in the direction away from the longitudinal axis of the guide bar.
Chain Saw
The disclosure provides a chain saw including a housing, a motor, a chain saw bar assembly, a tensioning assembly set on the housing, and an adjustment assembly set on the side cover corresponding to the tensioning assembly. The chain saw bar assembly is detachably connected to the first housing through the combination of the tensioning assembly and the elastic components, the adjustment assembly is movably connected with the tensioning assembly, and the adjustment assembly can adjust the relative position of the tensioning assembly and the guide shaft, to tension the chain set on the circumferential direction of the guide bar and tightly lock the chain saw bar assembly between the first housing and the side cover.
Electric-power-driven working device
A chainsaw 1 (electric-power-driven working device) comprises a body case 10, a cutting attachment 20 (work tool), a motor 30 and a battery 90. A front portion 11a of the body case 10 houses the motor 30 and a battery mount-and-release portion 12 is formed on a rear portion 11b of the body case 10. The battery 90 mounted on the battery mount-and-release portion 12 extends in an upper-lower direction across and over a middle portion in a height direction of the rear portion 11b of the body case 10. The side handle 50 arranged to a side face of the body case 10 extends from the front portion 11a to the rear portion 11b of the body case 10. A rear end portion 52 of the side handle is disposed rearward of and below an output shaft 31 of the motor 30.
Chain and bar cassette and chainsaw guide bar with tension indicator
A chainsaw (100) includes a power unit and a working assembly powered responsive to operation of the power unit. The working assembly includes a guide bar (120) around 5 which a chain (210) is rotatable. The guide bar (120) includes first and second side plates (400, 410), a core (420) and a tension indicator (240). The first and second side plates (400, 410) each face other and extend away from a housing (110) to a nose. The core (420) is disposed between the first side plate (400) and the second side plate (410). The tension indicator (240) is provided at the core (420) and is visible at at least one of the first side plate 10 (400) or the second side plate (410). The tension indicator (240) is configured to indicate a chain tension based on a position of the guide bar (120).
Hybrid single and double wall case
A hybrid double and single wall case with two pivotally connected body portions which are single molded pieces that pivot between an open position and a closed position to respectively receive and contain a chainsaw. A portion of the body sections is configured as a double wall structure and a portion of one of the body sections is configured as a single wall structure.
Hand-Guided Treatment Device with Operating Element and Display Field
A hand-guided treatment device is configured for use in working positions tilted relative to each other by a tilt angle of at least 45° about a device longitudinal axis. The device has a device housing, a handle operating unit with a handle extending with a main direction component parallel to the device longitudinal axis and a finger-operable operating element within finger reach of the handle, and a display field arranged on an outside of the device housing with at least one optical display element. The display field is arranged offset relative to the operating element in a housing circumferential direction about the device longitudinal axis and extends in the housing circumferential direction over a housing edge and/or with a curved or kinked course.
