Electric pole loppers are provided. An electric pole lopper includes a handle, a connecting pole and a pruning component which are connected in sequence, wherein the pruning component comprises a casing, a control mechanism and, connected in sequence, a motive power mechanism, a drive mechanism and a cutter set, wherein the motive power mechanism and the drive mechanism are disposed in the casing, the cutter set is disposed at that end of the casing which is remote from the motive power mechanism, a switch connected to the motive power mechanism is provided on the handle, and the control mechanism is connected to the drive mechanism; the drive mechanism is a worm gear/worm drive mechanism or a ball screw drive mechanism.

Pruning shears include a cutting head with a spring-biased blade; a driving line connected at a first end to the blade; an elongated body; a handle; and a frusto-conical shaped wheel connected rotatably to the handle. The diameter of the wheel at a first end being smaller than the diameter at a second end. The line is wound into a spiral groove around the wheel at the first end; a second end of the line is attached to a second end of the elongated body; and the line wound around the wheel moves toward the second end of the wheel when unwinding a part of the line from around the wheel and winding another part of the line around the wheel for decreasing the distance between the first and second ends of the line, resulting in movement of the blade in relation to the jaw, when the handle is moved.

A lopper a lopping assembly mounted to an upper end of a pole, said lopping assembly includes a movable knife and a counter knife. The movable knife is connected via a first transmission and connection assembly to an operating assembly disposed at a lower end of the pole, which is configured to move the movable knife and/or the counter knife in a direction to one another. The operating assembly includes first and second actuating elements. The first actuating element is coupled to the first transmission and connection assembly and the second actuating element is coupled via a second transmission and connection assembly and releasable latching assembly to the first actuating element. Movement of the second actuating element away from the first actuation element causes, via the second transmission and connection assembly, a movement of the first actuating element in said first direction.

An electric pole pruner having a spring returned cutting head and equipped with a drive unit having an electric motor coupled to a drum via an epicyclic gear assembly is configured to reduce rotation speed and to increase torque. A string element is coupled to the drum of the drive unit, and to the cutting head so as to actuate the cutting head. The pole pruner further includes a locking arrangement to selectively lock or release a ring gear of the gear assembly so as to convert rotation of the electric motor into rotation of the drum when the ring gear is locked, and to convert rotation of the drum into rotation of the ring gear when the ring gear is released.

A precision pruner for selectively cutting twigs, branches, stalks and vines deep within a bush or shrub has an elongated tool portion with at least one notch. A first handle is stationarily disposed on the tool portion and a cutter portion is slidably disposed on the tool portion. A cutting edge is aligned with notch(es) in a normal position, and a second handle is pivotally disposed on the first handle portion such that squeezing the first and second handles together slides the cutter portion relative to the tool portion out of the normal position so that the cutting edge(s) and the notch(es) are moved towards each other, thereby cutting any material received within the notch(es).

A lopper or lopper head attachment may include a primary gear, a secondary gear, a ratchet gear, an engagement flag, a dampened lag bolt, and a cutting blade. The secondary gear may be enmeshed with the primary gear. The secondary gear may define a lag groove radially offset form the secondary axis. The ratchet gear may be rotatable about a secondary axis separately from the secondary gear. The engagement flag may be rotatably mounted to secondary gear to move between an unengaged position and a engaged position. The dampened lag bolt may be slidably received within the lag groove to move relative to the secondary gear between a permissive position and a restrictive position. The cutting blade may be in mechanical communication with the ratchet gear to be pivoted thereby, in the engaged position of the engagement flag, to a closed position from an open position.

An electric pole pruner having a spring returned cutting head and equipped with a drive unit having an electric motor coupled to a drum via an epicyclic gear assembly is configured to reduce rotation speed and to increase torque. A string element is coupled to the drum of the drive unit, and to the cutting head so as to actuate the cutting head. The pole pruner further includes a locking arrangement to selectively lock or release a ring gear of the gear assembly so as to convert rotation of the electric motor into rotation of the drum when the ring gear is locked, and to convert rotation of the drum into rotation of the ring gear when the ring gear is released.

An extendable garden shears includes: an outer tube, an inner tube, a telescopic control set, a cutting structure, a wheel unit and a pull string. Through the combination of the above structure, the shears are extendable without the pull string being directly exposed, and the shears has a cutting structure capable of providing different cutting angles.

A driving mechanism for use in a power tool and a power tool comprising the driving mechanism in connection with a motor and an operation member. The driving mechanism includes a sliding member arranged to drive the operation member, the sliding member is arranged to move between a first sliding position and a second sliding position along a longitudinal axis during an operation of the power tool so as to drive the operation member to move between a first operation position and a second operation position respectively.

The present invention discloses blade-heatable electric scissors and a control method. The electric scissors include a scissors main body. A first blade is arranged at a front end of the scissors main body; a heating sheet and a temperature sensor are arranged on the first blade, and the heating sheet and the temperature sensor are connected to a heating sheet drive circuit and a blade temperature detection circuit through a conduction cable respectively. Compared with the prior art, the present invention arranges the heating sheet on the shearing blade so that a cut can be subjected to high-temperature disinfection while a branch is pruned.
