A pruner is provided including a pruning mechanism including a pruning blade on a tip side, a pole connected to a base side of the pruning mechanism, and a hook mechanism including a hook that projects to a lateral side substantially orthogonal to a central axis of the pole and that is displaceable in a range from a first position where an end portion is away from the central axis to a second position where the end portion is close to the central axis. The hook is configured to keep the first position when first external force in a direction from the base side toward the tip side is applied, and be displaced from the first position to the second position when second external force in a direction from the tip side toward the base side and/or a direction from the lateral side toward the central axis is applied.

A working machine includes: a working device mounted on a front end of an operating rod; a power device mounted on a base end of the operating rod; and the operating rod equipped with a hanging tool for a shoulder belt. The hanging tool includes a stopper. The stopper is configured to allow a pair of fastening portions to approach or be spaced from one another while sandwiching a circumference of the operating rod. The fastening portions include a through hole orthogonal to the longitudinal direction of the operating rod. A base end of an operating lever is pivotably supported around a rotating shaft parallel to the operating rod on the second end side of an operating shaft. The operating lever is rotated such that a front end of the operating lever approaches a side surface of the operating rod to fasten the stopper.

A handheld driving apparatus is provided for mowing or cutting an object. The driving apparatus comprises: a container, an action unit and a controller. The container is configured to extend from a rear side where a user is located toward a front side where the object is located. An action unit is provided on the front side of the container and configured to drive in such a manner that a mechanical action for mowing or cutting the object can be applied to the object. A controller is configured to execute a program so as to: in a driving step, drive the action unit by controlling a drive output of the action unit to a target value, in a monitoring step, monitor a state or a behavior of the drive output with respect to the target value during the control in the driving step, and in an adjusting step, adjust the target value based on the state or the behavior during the monitoring.

Driving apparatus, control method of driving apparatus, and non-transitory computer readable media storing program

An electric working machine capable of efficiently cooling components disposed inside, as well as simplifying assembling work and reducing man-hours and production cost. A motor, control board for controlling the motor, rod fixture secured to the front side of the motor, and air guiding partitioning member secured to the rear side of the motor form a motor assembly. The air guiding partitioning member includes a partitioning plate hermetically partitioning between air exhaust and intake ports provided with a predetermined interval longitudinally in the body casing. The partitioning plate has an air guiding window for delivering cooling air taken in from the air intake port to an opening for sucking air on the front side of the motor through a space between the motor and body casing. The control board is disposed on the rear side of the partitioning plate.

Electric working machine

An electric working machine and method for assembling the same that do not require specific jigs, so as to facilitate assembling work and reduce man-hours and production cost. A motor assembly is relatively inserted into a body casing, with a mounting base disposed behind a partitioning wall portion allowing a tubular fixture to project through an insertion hole toward the front of the partitioning wall portion, and a temporarily securing mechanism temporarily secures the motor assembly to retain the position of the motor assembly by automatically moving it in rotating and two orthogonal directions on a plane along the partitioning wall portion, so as to coaxially arrange the tubular fixture and insertion hole, and through-hole and screw hole of the mounting base for screwing the bolt. In such a temporarily secured state, the motor assembly is finally secured by screwing the bolt through the through-hole into the screw hole of the mounting base.

Provided is a battery-powered working machine including a protective bracket which is able to be secured to a casing while being in engagement with a battery pack, which is capable of preventing theft of the battery pack, and which separates a casing-side connection terminal from a battery-side connection terminal at a distance to keep the casing-side and battery-side connection terminals and out of contact with each other.
