Technical Field

[0001] The utility model relates to the technical field of resistors, in particular to a detachable resistor. Background Art

[0002] Resistors, which are generally called resistors in daily life, are current limiting components in circuits. They usually have two pins. After being connected to the circuit, their resistance is generally fixed, which can limit the current passing through the branch connected to it. Resistors whose resistance cannot be changed are called fixed resistors, while those whose resistance can be changed are called potentiometers or variable resistors.

When the resistor body needs to be disassembled, the servo motor is started to drive a threaded rod and a gear to rotate, and then the other gear and the threaded rod are rotated synchronously through the chain. Since the left and right outer walls of the connecting plate are respectively fitted and slid on the left and right inner walls of the slide groove, and the rod body of the threaded rod is screwed through the connecting plate, the connecting plate will not rotate but only rise and fall.
