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.

A hand tool includes a first jaw; a second jaw rotatably coupled to the first jaw, the second jaw including a first set of projections and a first bearing surface, the first bearing surface having a first curvature; and a lever coupled to the first jaw, the lever including a second set of projections and a second bearing surface, the second bearing surface having a second curvature. During a movement of the first and second jaws from a full open position to a full close position, the first and second sets of projections are at least partially engaged to prevent a slippage between the first and second bearing surfaces that are in a rolling contact during the movement of the first and second jaws from the full open position to the full close position.

A pruning device comprises a pair of cooperating blades that are pivoted together and a pair of rigid elongate handle stems movable to and from each other for a user to operate the cooperating blades. Each handle stem is telescopic, having a first portion and a second portion that is slidably extendable relative to the first portion and the blades. Each handle stem has attached thereto a first grip located adjacent a distal end of its moveable portion and a second grip spaced apart from the first grip and located between the first grip and the blades.

A fruit picker and branch trimmer comprising a frame or partial frame coupled to a stick, and at least one rotating jaw. The jaw is triggered by blades or pins coming in contact with the stem or branch, or by the fruit itself pushing on the jaw. Simply, the jaw rotates by only pulling on the stick. When a jaw rotates, its non-hinged sharp end presses the stem or branch on an obstacle, hence cutting the stem or branch. When two jaws rotate the stem or branch is cut when the sharp edges of the jaws come together. Another type of jaws has at least one elongated recess, when a stem or branch falls into the elongated recess it will be twisted and broken when the jaw rotates.

An extension rod for a power tool may include a plurality of rod portions, with a first connector and a second connector connecting two of the rod portions. The second connector has a sleeve and a primary fastener. The first connector has a guide rod sized for insertion into the sleeve. The first connector also has a secondary fastener engaging with the primary fastener. A first guide ring, a second guide ring, and a third guide ring are located between the guide rod and the sleeve. The first guide ring, the second guide ring, and the third guide ring each include respective conical faces. At least one of the first, second, and third guide rings defines a notch.

A gardening tool may include an outer tube, at least a middle tube, and an inner tube which are sleeved and connected in sequence. Each of a first end of the outer tube and a first end of the middle tube is connected to a pressing member, and through the pressing members, the middle tube and the inner tube are adapted to be firmly positioned after the middle tube is pulled out from the outer tube and the inner tube is pulled out from the middle tube to adjust the length of the gardening tool.

The present invention relates to a shearing tool such as scissors, comprising first and second cutting members pivotally coupled with each other, and a linkage pivotally coupled to the first and second cutting members, whereby the linkage and one of the first and second cutting members form together a compound lever mechanism. A force applied by an operator onto the shearing tool increases as an output by the linkage, and the increasing force is conveyed to that cutting member so that the cutting power of the shearing tool increase to allow hard-to-cut materials to be cut manually and easily with less effort from the operator.

A cutting tool is disclosed with an elongated, hollow first handle. An extension mechanism fixed with the first handle's distal end features a housing with a blade slot and blade connected with gears rotationally fixed with the housing. The proximal end of the housing's extension rod slides within the first handle, and its distal end terminates at a rigid hook with a first gear rack that engages the pinion gears. The cutting tool is suited for safety and ease-of-use in small, tight or otherwise difficult to reach environments.
