An impeller is operatively coupled to the motor and driven by the motor to create suction pressure to draw the debris out of the debris accumulation chamber and into a collection bag.

Abstract: A rear-pivot-point lever, cam-enabled, captured-spring-biased nail trimmer is disclosed. A base plate with a front cutting edge is pivotally connected to a top plate with a front cutting edge at a central base pivot point. A spring is captured between the plates in a manner that biases the front cutting edges of the trimmer apart until the trimmer is actuated. The top plate has a rear end for receiving and pivotally cooperating with a cammed actuating lever, the front end of which is pushed downward/forward to act against the bias of the spring to close the cutting edges to cut a nail. Because the lever arm pivots at a pivot point or axle at or near the rear end of the trimmer, the thumb and finger(s) of the user are positioned at or near the front of the trimmer during use, and therefore, near the nail being trimmed. This results in stable and non-twisting operation. The lever may be swung around the plates of the trimmer to rest below the bottom plate in a compact configuration.

Abstract: An electric pruner includes a housing, a motor accommodated within the housing, a transmission mechanism, a movable blade, and a fixed blade extending from the front end of the housing. The fixed blade is fixedly mounted on the housing, and the movable blade is rotatably connected to the fixed blade via a shaft and driven by the motor via the transmission mechanism. A locking device manually operable by the user is arranged on the shaft for locking the movable blade, the locking device being switchable between a first position where the movable blade is locked to stay connected with the transmission mechanism and a second position where the movable blade is releasable from the transmission mechanism. Thus, the replacement of the movable blade is very simple and convenient.

Abstract: The invention relates to a pipe disconnecting device, comprising a disconnecting device, which has a rotary body. The rotary body comprises a tool carrier for a disconnecting tool. A protrusion projects transversely to the rotational axis of the rotary body away from the rotary body or away from the tool carrier. At least one handle is attached to the protrusion, the handle extending across a region of the surface of the protrusion and forming a reach-through opening between the handle and the surface of the protrusion for a hand reaching for the handle.

Abstract: Apparatus and equipment for making glass sheet from a glass ribbon including scoring, bending and separation in vertical state with improved glass ribbon stability provided by edge restrainers located above the score-line that also travel with substantially the same vertical velocity with the elastic ribbon. The edge restrainers on both sides of the glass ribbon serve to limit the motion and perturbation of the ribbon during scoring, bending and separation, advantageously by tensioning the glass ribbon where needed. The invention can reduce disturbance of the glass ribbon in upstream visco-elastic and/or viscous zones due to scoring, bending and separation, therefore enhance forming process stability and product attributes such as thickness variation, stress and stress variation, and the like. The invention can be particularly advantageous for making glass sheet with large width and/or low thickness using the fusion down-draw, slot down-draw, re-draw down-draw, and other down-draw processes.

Abstract: A folding tool includes a bolster that acts as a safety and lock release. The tool may be designed for one-hand opening. An implement is held in a stored closed position by a safety formed by the bolster and a button style lock. The implement can be opened to the ready-for-use position by rotating the bolster to release the safety, and then rotating the implement. Once the implement is open, the bolster is rotated back to its original position setting the lock for the tool.

Abstract: A safety mechanism for a utility knife is provided to prevent more than one retraction of the blade shield for each trigger actuation. A separable linkage extends between an actuator and a strut, and has a seat member and a deflecting member that are linked together when the actuator is not depressed and the strut is in the safety position blocking the retraction of the shield. The separable linkage is configured to transmit the pressing action of the actuator to the strut to disengage it from the bracket. The separable linkage is configured to delink as the shield retracts. If the actuator continues to be pressed in after the shield returns from being retracted, the safety mechanism prevents relinking of the seat member and the deflecting member, due to the deflecting member being deflected away from the seat member in a substantially longitudinal direction.

Abstract: A folding knife capable of preventing automatic folding, which includes a handle having first, second and third plates, and a blade pivotally connected between the first and second plates by a pivot. The second plate is provided with a resilient stopper having a first end fixed to the second plate and a second end extending toward the first plate in a slanting manner. The third plate has one side corresponding in position to the second plate and concavely provided with an engaging hole. When the blade is fully rotated out of the handle, the second end of the resilient stopper presses against one end of the blade and thereby keeps the blade fully rotated out of the handle. Thus, when a force applied to the blade is excessively large, the resilient stopper will not be shifted away from the position against the blade.
