A hedge trimmer comprises a cutter assembly and a drive operating portion for driving and operating the cutter assembly is provided. The drive operating portion in the hedge trimmer includes a body with a power source, a front handle, and a rear handle. The front handle includes a rod-shaped front gripping portion provided to protrude laterally of the cutter assembly and a trigger lever displaceably mounted on the front gripping portion, allowing and releasing transmission of drive power from the power source to the cutter assembly. When the hedge trimmer is viewed laterally in a state where a thickness direction of the cutter assembly being a vertical direction, the trigger lever is arranged to protrude from the front gripping portion in a direction inclined forward with respect to the vertical direction on a lower side of the vertical direction.

An oscillating gardening device includes a drive unit and at least one cam gear that is configured to be driven by the drive unit and has at least one guide section configured to guide at least one element. The guide section is rotatable about an axis of rotation and closed relative to the rotation axis in the circumferential direction. The guide section is arranged eccentrically with respect to the axis of rotation and deviates at least substantially from one or more of a circular shape and a circular ring shape in the circumferential direction. The oscillating gardening device in at least one embodiment is configured as one or more of hedge shears, grass shears, and branch shears.

The reciprocating cutting blade apparatus includes: a pair of reciprocating cutting blades disposed to overlap one another in a thickness direction; a support member configured to reciprocably support the reciprocating cutting blades in a longitudinal direction; and an adjustment mechanism configured to adjust a gap between the reciprocating cutting blades on a lower surface side of the support member. The adjustment mechanism includes: a screw hole provided in the support member; an adjustment screw including an external thread configured to threadedly engage with the screw hole through long holes provided in the reciprocating cutting blades; and a nut configured to threadedly engage with the external thread protruding from an upper surface of the support member to fix the external thread to the support member. The external thread protruding from the upper surface of the support member includes an operated portion configured to be operated to turn the adjustment screw.

Various trocars and trocar supports are provided for allowing an insufflation port on the trocar to be coupled through the trocar support to an insufflation fluid. In one embodiment, the trocar includes a housing, a cannula extending through the housing, and an insufflation port projecting from the housing. A trocar support is provided having an opening that receives the insufflation port on the housing such that the insufflation port is unobtrusive during use and can be connected and disconnected rapidly.

A work apparatus has a gear unit which is arranged in a gear housing. The gear unit includes a drive part arranged in a first housing part of the gear housing and an output part arranged in a second housing part. The two housing parts are connected to each other via a pivot joint which permits pivoting of the second housing relative to the first housing part about a pivot axis. The pivot joint has a clamping device for bracing the two housing parts in the direction of the pivot axis. The force exerted with the clamping device on the two housing parts is adjustable via a clamping element. To avoid loosening or releasing of the clamping device even after frequent pivoting, the clamping element moves during clamping in the direction of a clamping axis which encloses an angle which is more than 10 with the pivot axis.

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.

A hedge trimmer includes a blade assembly, a power assembly, a battery pack, a connecting rod and a handle assembly. A first end of the connecting rod is fixedly connected with the power assembly and a second end of the connecting rod is connected with a battery pack cavity. The battery pack is mounted in the battery pack cavity, and the power assembly accounts for less than 46% of a weight of the hedge trimmer. The disclosure reduces a weight of the power assembly at a front end through placing the battery pack behind, and a hedge trimmer may not turn its head, which shortens an overall length requirement of the hedge trimmer. Therefore, a weight of the hedge trimmer is reduced, and a structure of the hedge trimmer is compact.

A working machine may include a working unit including a working mechanism, an electric motor, and a motor housing, a control unit, a base, a rear housing, a front handle, and a rear handle. The base may include a passage. The motor housing may include an inner air inlet and an outer air outlet. The rear housing may include an outer air inlet and an inner air outlet. A cooling air passage may be defined in which air flows from the outer air inlet to the outer air outlet through an inside of the rear housing, the inner air outlet, the inside of the passage, the inner air inlet, and an inside of the motor housing. As viewed along a front-rear direction, the inner air inlet and the inner air outlet may overlap each other.

A hedge trimmer includes a front end device including at least a cutting assembly extending along a longitudinal axis and a front housing for supporting the cutting assembly; a rear end device including at least a motor for driving the cutting assembly and a rear housing for supporting the motor; a connecting rod connecting the front end device to the rear end device; a power device supported by the rear housing and configured to supply electrical energy to the motor; a main handle connected to a first switch; and a second switch disposed on a front side of the first switch. In a direction of the longitudinal axis, the distance between the first switch and a first cutting tooth of the cutting assembly is greater than or equal to 120 mm and less than or equal to 1000 mm.

A trimming machine capable of suppressing damage to a gear when blades are locked, with a simple structure without increasing weight and cost. The trimming machine includes: an electric motor; a blade drive gear rotationally driven by the electric motor; an eccentric cam provided in the gear; and a pair of blades relatively slidably facing and contacting each other, in which the eccentric cam is adapted to reciprocate the pair of blades in relatively opposite directions along the longitudinal direction of the blades, thereby grinding cutting edges against each other, the cutting edges provided in a protruding manner with gaps therebetween in the pair of blades, and a shock absorbing portion is provided between a connecting portion connected to the eccentric cam and the cutting edges in each of the blades.
