The disclosure provides an electric pruning machine which comprises a fixed blade, a movable blade, and a driving device for driving the movable blade to move towards the fixed blade; an edge portion of the fixed blade is provided with a convex portion protruding from a surface of the edge portion of the fixed blade; and the convex portion is located at a middle position of the edge portion on the fixed blade. Arrangement of the convex portion on the fixed blade can prevent tree branches from being stuck and not moving forward when the fixed blade and the movable blade move relative to each other to shear the tree branches, so as facilitate tree branch pruning and promote shearing of the tree branches.

A tool is provided, the tool including a handle, a tool head, a first gear, a compound gear, a shaft, and an actuating member coupled to the shaft. The handle extends along a longitudinal direction. The tool head is configured to receive a motive force to selectively engage or disengage the tool head. The first gear is operably coupled to the tool head. The compound gear is selectively coupled to the first gear. The shaft extends through the compound gear and is affixed to the shaft. The actuating member is coupled to the handle. Movement of the actuating member along the longitudinal direction selectively engages or disengages the compound gear and the first gear.

A tree pruner configured to reduce the width of the device to facilitate reduction of shipping costs and store space. The tree pruner comprises a leaf spring having a lower end mounted onto a lower portion of a lever, and an upper end connected to a first end of a self-locking pin, wherein the self-locking pin penetrates the lever. When the lever is at a first position at shipping or store front, the leaf spring is in tension to exert force on the self-locking 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 self-locking 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 method for manufacturing blade beds of a garden shear, wherein each of two blade beds has a length and a thickness far less than the length; the method includes: using extrusion method to extrude two blanks in directions parallel to directions of thickness of two blade beds respectively, wherein cross sections of the two blanks are shaped into the two blade beds; slicing the two blanks perpendicularly to the extruding direction into a plurality of pieces at intervals of distances equal to the thickness of the two blade beds respectively; and chamfering a plurality of peripheries of the pieces by punching.

A tree pruning assembly is provided. The assembly comprises a lopper comprising two lopper handles pivotally connected to one another and a respective cutting blade arranged on an end of each of the lopper handles, a pruner adapted to be detachably connected to either one of the lopper handles, a saw adapted to be detachably connected to the other of the lopper handles, and a respective connection device for detachably connecting each of the pruner and the saw to a respective one of the lopper handles. The connection devices may be of identical construction so that the saw and pruner can each be connected to either of the lopper handles. A connection device for connecting a saw or pruner to a lopper handle is also encompassed by the present invention.

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 hand operated cutting tool includes a first handle coupled to a first cutting member, the first handle having a first set of projections; and, a second handle coupled to a second cutting member and movably coupled to the first handle, the second handle having a second set of projections. The handles are movable between a full open position and a full closed position, wherein a first region of movement is defined by the first and second sets of projections being at least partly engaged, and wherein a second region of movement is defined by the first and second sets of projections being disengaged.
