摘要： A utility knife includes a handle having a body and a receiving aperture. The utility knife further includes a collet at least partially receivable in the receiving aperture, and a sleeve that is engageable with and that surrounds the collet. The collet is configured to alternately receive one of a portion of a blade of a first type in a first slot and a portion of a blade of a second type in a second slot. The collet and the sleeve are co-rotatable relative the handle to move the collet to a secured position in which one of the blade of the first type and the blade of the second type are secured to the collet.

摘要： Systems and methods for under-voltage protection features in power tools. One power tool provides a motor, a power source, a voltage sensor, and a controller. The power source is configured to selectively provide power to the motor. The voltage sensor is configured to sense a voltage of the power source. The controller is configured to monitor, with the voltage sensor, the voltage of the power source and reduce, when the voltage of the power source is less than or equal to a first threshold value, a current provided from the power source to the motor. The controller is configured to stop, when the voltage of the power source is less than or equal to a second threshold value, providing the current from the power source to the motor.

摘要： A backpack sprayer is disclosed for dispensing different fluids. The backpack sprayer includes a housing with a bottom face and a dispensing assembly. The housing defines a fluid container, a battery compartment for receiving a battery, and a chamber for receiving a control assembly and a pump assembly. The dispensing assembly can dispense fluid from the fluid container. The pump assembly is configured to pump the fluid from the fluid container to the dispensing assembly. The control assembly is configured to control the pump assembly. The battery compartment is positioned above the bottom face with a first height therebetween, and the control assembly is positioned above the bottom face with a second height therebetween. The control assembly includes a rotatable dial, and the rotatable dial has a coupler for coupling a rotatory movement and a cam surface engaged by a follower for controlling on and off of the pump assembly.

摘要： A control system for a power tool is disclosed. The control system comprises: a sensing unit configured to sense an operating characteristic of the power tool; a first control unit configured to determine whether the operating characteristic is within a safe operational range, and to output a first control signal at least partially based on the determination; a second control unit configured to determine whether the operating characteristic is within a safe operational range independently of the first control unit, and to output a second control signal at least partially based on the determination; and an output unit configured to receive the first and second control signals and to activate the power tool when the first and second control signals are received.

摘要： A powered fastener driver includes a first cylinder, a first piston positioned within the first cylinder, a second cylinder in fluid communication with the first cylinder, and a second piston positioned within the second cylinder. The first piston is moveable between a top-dead-center position and at or near a bottom-dead-center position and the second piston is moveable between a top-dead-center position and a bottom-dead-center position to initiate a fastener driving cycle. A drive blade is coupled to the second piston for movement therewith and a drive mechanism is configured to drive the first piston between the top-dead-center position and at or near the bottom-dead-center position. The drive mechanism includes a crank arm that rotates less than 360 degrees for moving the first piston from at or near the bottom-dead-center position and the top-dead-center position and then back to at or near the bottom-dead-center position to complete the fastener driving cycle.
