    摘要: A blade assembly for a hair cutting apparatus includes a first blade having teeth extending along a first blade edge, and a second blade having teeth extending along a second blade edge. A distance between the first and second blade edges defines a blade gap. A yoke is coupled to the second blade and configured to convert motion of a drive into reciprocation of the second blade relative to the first blade to cut hair. A spring includes a spring base and at least one spring arm configured to reciprocate with the second blade. A guide assembly includes a guide and a spring retainer, the guide being positioned between the first blade and the second blade, and the spring retainer fixing the spring base relative to the first blade, wherein in response to moving the guide relative to the first blade, the blade gap changes.

    摘要: A tool for bending an elongated workpiece includes a shaft having a first shaft portion and a second shaft portion, and a coupling assembly coupling the first shaft portion and the second shaft portion. The coupling assembly has a locked configuration in which the coupling assembly inhibits movement of the first shaft portion relative to the second shaft portion and an unlocked configuration in which the coupling assembly permits movement of the first shaft portion relative to the second shaft portion. The tool also includes a shoe coupled to the second shaft portion. The shoe has a curved bottom portion and a hook configured to hold the workpiece against the curved bottom portion. The curved bottom portion is engageable with the workpiece to bend the workpiece.

    摘要: Various aspects of tape measures with one or more of a sensor, a motor, and a clutch, are shown. The sensors described herein detect, through various mechanisms, the position of the retraction system of a tape measure. The measurements by the sensors may be used to control a motor to adjust an amount of tension in the spiral spring of a tape measure. In various embodiments a motor interacts with the retraction system of the tape measure via a clutch, which moderates an amount of force that the motor can communicate to the retraction system.
