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 switch-free multi-cutting mode shearing tool includes a shearer including a first handle and a second handle pivotally connected together, a cutter blade pivoted to the first handle, a link pivoted to the second handle, and a pushing element mounted at the second handle. The cutter blade has a cutting edge protruding over a front end of the first handle, an actuation portion projecting between the first and second handles, an elongated slot located in the actuation portion and a plurality of engagement grooves inside the elongated slot. The link has a pin located at a movable end thereof and inserted into and movable along the elongated slot and selectively engageable into one of the engagement grooves, such that when the first and second handles are closed toward each other, the pushing element is forced to touch and push the actuation portion of the cutter blade.

For manually actuated shears with a ratchet mechanism it is proposed to provide an additional lever that circumvents the ratchet mechanism and enables the operation of the shears in a direct cut mode in which a single closing process of the handle levers also causes complete closing of the blade arrangement.

A cutting device for the chipless cutting of a material comprises a cutting part and a supporting part. The cutting part and the supporting part are designed to be rotated with respect to one another about an axis of rotation between an open position and a closed position. A hand lever is articulated to the supporting part for pivoting about a pivot axis. A ratchet mechanism converts a back-and-forth motion of the hand lever into a continuous rotational motion of the cutting part toward the closed position. The ratchet mechanism includes a toothing and a drive pawl, which can be brought into an effective position with respect to the toothing. Furthermore, the cutting device comprises a coupling mechanism, which converts a one-time pivoting motion of the hand lever into a rotational motion of the cutting part. A separate coupling element transmits force from the hand lever to the cutting part.

A pair of hair cutting or pet scissors that have two blades operationally connected by a dual taper, dual threaded bolt and a nut for adjustment and a nut for assembly. The assembly allows for the scissor blades to be brought into tighter or looser frictional contact with each other without being disassembled. There is a tool that engages the bolt to rotate either of the nuts separately for adjusting the feel of the blades or for disassembly and repair or sharpening.

The present application discloses an anti-loosening structure, a folding knife and scissors applying same, wherein the anti-loosening structure includes a rotating shaft, a locking screw and a locking element. The rotating shaft is D-shaped, and the locking element is arranged on the rotating shaft which is static relative to the rotating shaft. The locking screw is arranged inside the rotating shaft and is threadedly connected with the rotating shaft or the locking element. The rotating shaft has a first end and a second end, wherein a limiting part is arranged on the first end of the rotating shaft, and the locking element is set on the outer side of the second end of the rotating shaft and is threadedly connected with the second end.

Adding weights in a prescribed manner to a scissors will provide a tool allowing users (typically students or children) to better develop fine motor skills. This is particularly helpful when helping users deal with neurological issues that may challenge their abilities. The weighted scissor will be heavier than a typical scissors, which can help in skill development. In some embodiments, the weight is focused in the handles thus requiring addition effort to operate.
