The present invention is directed to a small hand-held garden tool, for example a hedgetrimmer, having an electrically powered powerhead, and a detachable pole assembly. The powerhead can be used alone to cut nearby vegetation or in combination with a pole assembly to reach vegetation farther away. The powerhead has a separate handle and motor chamber, with the pole assembly being secured to the motor chamber. Actuation of the powerhead is controlled by a trigger on the handle. However, when connected to the pole assembly, actuation of the powerhead is controlled by a second trigger on the pole assembly.

A method is provided for type-specific operating of an electric drive unit, wherein the drive unit is configured for coupling and driving a tool unit selected from a set of different types of tool units. The set includes at least one rotatory tool unit and at least one non-rotatory tool unit. The method includes: driving of a coupled tool unit by the drive unit; identifying operating data of the drive unit during the driving procedure; determining, based on the identified operating data, whether the coupled tool unit is a rotatory tool unit or a non-rotatory tool unit; and controlling the drive unit in a rotation control mode if the coupled tool unit is determined to be a rotatory tool unit, or in a non-rotation control mode if the coupled tool unit is determined to be a non-rotatory tool unit.

An apparatus is disclosed that is connectable to a conventional chain saw to extend the operable reach of the chain saw. This apparatus includes a support assembly to provide support against a user's leg or body portion when cutting an elevated item. The apparatus helps to elevate and control a chain saw, while cutting or trimming objects with the chain saw. The apparatus includes operationally secure mounting means to firmly engage the handles of the chain saw, and to maintain the saw in proper operative alignment and position. The apparatus reliably and securely engages a chain saw handle without requiring modification of the original chain saw equipment. The apparatus provides a mounting assembly which does not engage or otherwise adversely contact fragile plastic parts of the chain saw, such as the engine housing. The apparatus provides an assembly for remotely operating a throttle or a trigger of the chain saw.

A gardening and/or forestry apparatus has a support element. The support element supports an eyelet. The eyelet is configured to incorporate an apparatus securing element. The gardening and/or forestry apparatus also has an element receiving device. The support element and the element receiving device are configured to receive the support element in the element receiving device either in a first rotational position or in a second rotational position differing from the first rotational position and to secure the support element against rotation by form-fitting to the element receiving device.

A handheld trenching apparatus and method of forming a trench in ground using the apparatus. The apparatus has a frame, a cutting head, and a drive. The cutting head has a ground penetrating portion with a plurality of cutting members that are caused to be moved in a controlled path by the drive. The frame has an elongate frame part with the cutting head at one frame part end. The frame further has at least one graspable region spaced lengthwise of the elongate frame part from the first elongate frame part end. The ground penetrating portion is directed into the ground and while engaging the at least one graspable region the ground penetrating portion is moved in a trench forming direction as the drive is operated to thereby form a trench.

An unmanned pruning vehicle includes a pruning device configured to prune plant material from a plant. The unmanned pruning vehicle also includes a processing circuit is configured to control operation of the pruning device to prune a plant.

A handheld electric tool includes a working device for performing a function of the handheld electric tool, a powering device for provide a driving force to the working device, and a connecting device for connecting the working device and powering device. The powering device includes: an electric motor, a power housing having an air inlet and an air outlet, a transmission mechanism for transmitting power generated by the electric motor and a circuit board for controlling the electric motor, a fan can be driven by the electric motor to provide an airflow which flows from the air inlet to the air outlet. The circuit board, the transmission mechanism and the electric motor are disposed between the air inlet and the air outlet such that the airflow flows through the circuit board, the transmission mechanism and the electric motor successively. The handheld electric tool has excellent cooling effect.

A battery powered octocopter drone with a protective frame. An articulating arm is mounted to the drone with a battery powered chain saw positioned along the end of the articulating arm. The chainsaw allows for the trimming of remote trees and bushes previously only accessible by a ladder or bucket lift. The drone is adjustable forward/aft to compensate for the center of gravity. The drone includes a remote control receiver, telemetry and an antenna allowing an operator to control all aspects of the drone from a remote position.

A power tool is provided with a drive motor and a tool unit with a tool driven by the drive motor. A guide tube with telescoping section with external and internal tubes is provided, wherein the internal tube is longitudinally slidable within the external tube. A clamping device secures the internal tube relative to the external tube and has a clamping member supported rotatably relative to the internal tube and connected by a thread connection to the external tube. The clamping device is provided with a clamping ring with an opening arranged about an outer circumference of the internal tube. Compression of the clamping ring in longitudinal guide tube direction effects a size reduction of the clamping ring opening. The clamping ring has a first axial face supported relative to the external tube and a second axial face supported relative to the clamping member.

The disclosure provides a multi-purpose portable gardening tool with multiple heads and combinations, belonging to the technical field of electric gardening tools. It solves the technical problems that the existing gardening tools have single function and are inconvenient to carry. The multi-purpose portable gardening tool with multiple heads and combinations includes a main machine, a function head, an extension tube, an extension intermediate head and a function intermediate head; the function head or the extension intermediate head is in spigot joint with a head end of the main machine, a head end of the extension intermediate head is connected to the extension tube having the function intermediate head at a head end thereof, and the function head is in spigot joint with a head end of the function intermediate head. The gardening tool in the disclosure at least includes three function heads, and may further extend more functions and methods of application by combining the function heads to the main machine and combining the main machine to the extension intermediate head, the function intermediate head and the extension tube, so that the gardening tool has more abundant functions to carry out multi-job operations only by one set of equipment, thereby improving convenience of use.
