Abstract:
An electronic fat gauge comprising a main body and a clamping lever pivotally connected to said main body to move in lever motion;said main body defines an inner space with a predetermined height and has a substantially P-shaped configuration; a right side of said substantially P-shaped main body, as viewed in front of said fat gauge, being a transversely extended control portion on which a liquid crystal display and a console are provided, said console having push buttons provided thereon for different purposes; a left side of said substantially P-shaped main body being a longitudinally extended and elongated seat portion that further including a lowered top zone, a middle pivot seat, and a bottom extended part having a flat-topped projection provided near a free end thereof;said clamping lever including a middle pivot portion rotatably mounted in said pivot seat to allow said clamping lever to move in lever motion relative to said main body, a shorter depressing arm extended from one end of said middle pivot portion to upward extend above said lowered top zone and define an angle between said depressing arm and said lowered top zone, and a longer measuring arm extended from another end of said middle pivot portion opposite to said shorter depressing arm to extend above said bottom extended part of said seat portion of said main body;a variable resistor mounted in an inner space of said pivot seat with an adjusting and controlling shaft of said variable resistor horizontally extended through two fixed shaft holding plates said adjusting and controlling shaft being locked between said middle pivot portion of said clamping lever and a covering member screwed to a bottom of said middle pivot portion, such that said adjusting and controlling shaft always rotates along with said middle pivot portion of said clamping lever; andan electronic control circuit provided inside said main body and electrically connect to said liquid crystal display and said variable resistor;whereby when said depressing arm of said clamping lever is depressed and causes said middle pivot portion to rotate, said adjusting and controlling shaft of said variable resistor is brought to rotate synchronously with said measuring arm, wherein the position of said measuring arm is converted into an electronic signal that is then sent to said electronic control circuit, where said signal is further converted into a value measurement for displaying in said liquid crystal display.
