An electrically powered rotary trimmer adapted to trim external portions of an agricultural product or other plant material. The trimmer may include an electric motor which rotates two or more trimming portions. The trimmer may include a handle with a battery. The trimmer may include a trim guard which may be rotatably adjustable. The trimmer may be adapted to plug into an external power source, which may be an external battery or a cellular telephone.

The present invention provides a cutting work machine, wherein a cutter unit includes upper and lower blades, which are connected to an upper cutter support, and a guard member that is provided on the upper cutter support. Both blades reciprocate in opposite front-back directions. The guard member includes a guard plate that projects to the right from the upper cutter support and a fixed blade that projects to the left from the upper cutter support. Front edge portions of the guard plate and the fixed blade are positioned forward of foremost cutting edges of both blades. The fixed blade faces forward against the foremost cutting edge of the upper blade.

A power tool system includes a first power tool and a second power tool. The first power tool includes a first connecting rod having a first working assembly, a second connecting rod having a first battery assembly, a first connector having a first connector portion with terminals A, B and C and a second connector portion with terminals A′, B′ and C′. The second power tool includes a third connecting rod with a second working assembly, a fourth connecting rod with a second battery assembly and a second connector with a same structure as the first connector; voltages of the first and second battery assemblies are different; terminals A, B are connected with first working assembly, and terminals A′, B′ are connected with first battery assembly; and terminals B, C are connected with second working assembly, and terminals B′, C′ are connected with second battery assembly.

A hedge trimmer may include a body housing, a fixed plate, a blade and a chip receiver. A first engaged part may be disposed on a first side surface of the fixed plate and a second engaged part may be disposed on a second side surface of the fixed plate. The chip receiver may include a base part mounted on the fixed plate, a receiving part and an attachment part. The attachment part may include first engaging part, a second engaging part configured to be movable between an engaging position and a non-engaging position, and a manipulation part configured to move the second engaging part from the engaging position to the non-engaging position in response to a user operation. An upper surface of the base part is flat.

The present invention provides a working device, comprising a working portion and a grip portion. The working portion comprises a driving component and a working component driven by the driving component. The driving component comprises an electric motor and an electric motor housing. The electric motor housing comprises a housing body and a connecting portion located on a rear side of the housing body. At least one air intake hole is formed in the connecting portion, and is in communication with an inner cavity of the housing body. In the working device of the present invention, the driving component is provided with an air intake hole to allow air for cooling an electric motor to enter the interior of the driving component. Further, the working portion can be rotated with respect to the grip portion so as to have an increased working angle, and it can also be ensured that at least one air intake hole is always in communication with the outside when the working portion is in any angular position, so that the use efficiency of the electric motor can be ensured under any use condition.

A working machine may include a pipe including: an outer pipe; an inner pipe inserted in the outer pipe; a pipe holder fixed to the outer pipe; and a stopper disposed inside the outer pipe. The pipe holder includes a wall part. The inner pipe includes a fixing hole having a longitudinal direction in a circumferential direction of an outer circumferential surface of the inner pipe. A rear surface of the fixing hole has a shape extending along a plane orthogonal to a front-rear direction. The stopper includes: an abutting part that abuts the wall part from behind when the inner pipe extends to a maximum length relative to the outer pipe; and a protruding part configured to fit in the fixing hole of the inner pipe. A rear surface of the protruding part has a shape extending along a plane parallel to the rear surface of the fixing hole.
