Abstract

An electric tool comprises a case, a motor, a transmission element, a driving element, at least one steel ball, at least one elastic element, and a screwdriver head. The motor is provided in the interior of the case. The transmission element is installed in the interior of the case, and connected to the motor. The driving element is installed in the interior of the case, and one side of the driving element in opposition to the transmission element has at least one indentation. Each of the steel balls is set in each of the indentations. Each elastic element is set in the transmission element, and is pushed by the inner wall of the indentation. The screwdriver head connects to the driving element. When the screwdriver head is born a larger load, each steel ball escapes to another indentation, so the transmission element and the driving disc are separate and idle running to avoid that the workpiece, the lock element, the inner power of the tool, and the transmission element damage because of overloading. It provides the function of multi protection when overloading.
