The invention relates to manual pliers (1) which comprise a fixed cutting jaw (26) and a movable cutting jaw (23). The manual pliers (1) comprise a first maximal opening position in which it is possible to run through a working stroke part caused by the closure of the hand levers (2). In the first maximal opening position the latching lever (16) and a pushing lever (19) engage with a toothing (32) of the movable cutting jaw (23). With the actuation of the latching lever (16) it is possible to transfer the manual pliers into a second maximal opening position in which the opening angle of the hand levers (2) is larger than in the first maximal opening position. In the second maximal opening position the latching lever (16) and the pushing lever (19) do not engage with the toothing (32) of the movable cutting jaw (23). For the definition of the two opening positions, two stops are used which are formed by the latching lever (16) and a swivel bolt of the latching lever (16).

A control device of a cutting tool is revealed. For performing cutting, opening and closing, the cutting tool includes a pair of handles pivotally connected to each other and each handle having a blade. The control device is set on the handle and involved in opening or closing of the blades of the cutting tool. The control device includes a first component and a second component. The first and the second components are connected to and locked with each other tightly by a fastening structure. The control device is disposed on the handle closely, without loosening from the handle.

A pair of pruning shears with multi-stage actions for cutting branches with larger diameters is revealed. The pruning shears include a fixing member, a blunt member, a cutting tool, a crank member, a moveable handle, a first locking member, and a second locking member. The fixing member, the crank member and the cutting tool are pivotally connected. The cutting tool consists of a blade part and a curved teeth part. The first locking member and the second locking member are pivotally connected to the fixing member and the crank member respectively. Each locking member is disposed with a hook part, a first projecting rod, and a second projecting rod. The first projecting rod and the second projecting rod are arranged symmetrically. The first locking member and the second locking member are engaged with different teeth respectively at different stages. Thereby the pruning shears performs cutting at different stages.

A tree shear capable of reducing an opening degree of handles thereof, includes a shearing part, a first handle and a second handle. The shearing part includes a first blade and a second blade pivoted with each other. The first handle is connected with a first blade, the second handle has a front section and a rear section sleeved with each other, and the front section is connected with the second blade. A link rod has an end pivoted with the first handle and other end pivoted with the rear section of the second handle. While the two handles are opened, the link rod affects the front section of the second handle to move relative to the rear section of the second handle, so as to adjust a length of the second handle to reduce the opening degree of the two handles.

Loppers include first and second elongated handles that are both directly connected and indirectly connected through a linkage assembly. The first handle has a static blade having a concave shearing edge extending generally transverse from the longitudinal axis of the first handle. The second handle has a curved end portion that curves toward the first handle and is pivotally secured to the static blade. An articulated blade has a convex cutting edge and is rotatably secured to the static blade. A link connects the curved end portion to an end of the articulated blade. Movement of the second handle relative to the first handle pivots the curved end portion about the static blade, thereby moving the cutting edge relative to the shearing edge via the link. The static blade and articulate blade are offset from the handles and extend generally transverse to the longitudinal axis of the first handle.

Foldable, multipurpose shears can have a pair of shearing blades, each blade having a sharp side and a blunt side. The blades are connected to handles via a hinge, and the handles have one side that is straighter and another side that is more rounded or irregularly shaped. One of the blades includes a backward facing hook on the blade's blunt side. Additionally, the blunt side may have partially sharpened serrations. The blades can fold about the hinge for easier transport and storage and the shears are configured so that the hook does not extend past the handles when folded.
