A pruning shear device includes a pair of pruning shears with a lug located at a rear end of a cutter blade thereof, and a switch unit including a position-limiting member movable between a first position where the position-limiting member is abutted against the lug for enabling the pruning shears to perform in a normal operating mode for cutting off small tree branches through a single-stage force-applying operation and a second position where the position-limiting member is kept away from the lug for enabling the pruning shears to perform in an effort-saving operating mode for cutting off large tree branches through a multi-stage force-applying operation.

A handle assembly system includes first and second handle sections intended to be assembled with one another, means for retaining one of the first and second handle sections in the other of the first and second handle sections and means for securing by friction an assembly of the first and second handle sections, the friction securing means comprising a friction seal interposed between the first and second handle sections.

A tree pruner configured to reduce the width of the device to facilitate reduction of shipping costs and store space. The tree pruner includes a leaf spring having a first end mounted onto a first end of a lever, and second end connected to a first end of a stop pin, wherein the stop pin penetrates the lever. When the lever is at a first position in a rest condition at shipping or store front, the leaf spring is in tension to exert force on the stop pin to engage with an outer surface of a back hook to hold the lever at the position. When the lever is pulled to a second position for use, the leaf spring is at rest. The the stop pin penetrates all the way through the lever and engages with an edge of the back hook to serve as an end stop for the lever movement.

A telescopic hand tool, in particular a telescopic pruner. The telescopic hand tool comprises an outer tube, at least one intermediate tube slidable within the outer tube and an inner tube slidable within the intermediate tube. At least one tool head is connected or connectable to the front end of the inner tube. A back handle is detachably arranged at the back end of the outer tube. A pulling means is arranged substantially inside the tubes, wherein one end of the pulling means is connected to the back handle, while another end of the pulling means is connected to a fixing point at the front end of the outer tube. A number of deflection pulleys is arranged at the back ends of the tubes and at the front ends of the outer tube and intermediate tube, wherein the deflection pulleys are provided for redirecting the pulling means.

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 pruner includes a pruner body, a cutting system, an electric motor to provide driving power for the cutting system. Rotation of the electric motor in a first direction is provides a cutting action. A control system is provided for controlling the electric motor. The pruner further includes a blade stuck detection system to detect a blade stuck situation in which the cutting system is not able to reach the closed position, and the control system, as a response to detection of the blade stuck situation, is configured in a recut operation to rotate the electric motor in a second direction opposite the first direction, and then to rotate the electric motor in the first direction to actuate the cutting system towards the closed position.

A lopper or lopper head attachment includes a primary gear, a secondary gear, a ratchet gear, an engagement flag, a dampened lag bolt, and a cutting blade. The secondary gear is enmeshed with the primary gear. The secondary gear defines a lag groove radially offset from the secondary axis. The ratchet gear is rotatable about a secondary axis separately from the secondary gear. The engagement flag is rotatably mounted to secondary gear to move between an unengaged position and an engaged position. The dampened lag bolt is slidably received within the lag groove to move relative to the secondary gear between a permissive position and a restrictive position. The cutting blade is 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.

High branch scissors comprising a first long rod shell, wherein a first fixing sleeve is arranged at a tail portion of the first long rod shell, a handle is slidably arranged on the first long rod shell, a telescopic assembly is arranged in the first long rod shell, and a scissors assembly is arranged at the top of the telescopic assembly. The interaction between the moving pulleys and the first steel rope reduces the operating resistance when pruning. The operation of scissors assembly is capable of being controlled by means of the handle. The first gear and the gear scissors blade are engaged and the second scissors blade is movably connected to the gear scissors blade through a bolt, thereby achieving the shearing function of the scissors assembly. Through adopting the present invention, a large force is transmitted during pruning, and the efficiency is improved.
