Inventive description: [Technical field of invention] The machine tool can stop the invention relating to a switching device, in particular to an electric motor, and can automatically adjust the rotation speed of the electric tool machine motor, An improved switch for motor rotation. [Prior Art] In recent years, 'electric power tools have become an indispensable tool in everyday life. Whether it is to drill holes in the wall, or to assemble the wooden cabinets and shoe cabinets by themselves, the electric machine tools are not available. The electric power tool for the missing corner is mainly through a switch device "rigge", which usually includes an electronic control circuit and is connected to the motor of the electric machine. When the user presses a trigger button on the handle of the power tool machine, the electronic control circuit can be used to control the motor rotation of the power tool machine. However, the electronic control circuit of the power tool machine used is mostly They are designed to drive only the motor to rotate, and there are few designs that have other functions in addition to the rotation of the drive motor. The average person who uses the electrician and the operator often encounters the problem that the electric machine tool cannot be used for the purpose. To drill through the teeth < automatically adjust the speed and torque of the motor without the material, for example, using a lightning electric machine to drill the wall, The user can press the trigger button ^ to control the motor rotation of the 201115605 X electric machine tool through the electronic circuit. The motor of the electric tool machine is instantaneously weakened, and the hole is drilled instead, because the motor is driven by the motor speed. Too fast, so waste energy. But when the power tool machine touches the wall, the moment is caused by the excessive load effect of the bearing. If the electric tool machine is used, the load effect of the thin wood board is relatively small, and it seems to be The power consumption, that is, the switching device of the electric power tool that is wasted by the electric power, usually does not have the mechanism for automatically stopping the motor and the action of the motor, so that when the user ends the drilling operation, the evening # After γ (that is, 'release the knob button on the handle), if the motor of the motor continues to drive the bit to rotate at a high speed, it is quite unsafe. Therefore, the inventor of Benso has the above-mentioned control electronic tools. The electronic circuit of the motor has many shortcomings, so it is extremely difficult to research and create the improved acceleration and deceleration mechanism control module of the invention. SUMMARY OF THE INVENTION The main object of the present invention is to provide an improved switching device that includes a compensating electronic circuit that automatically adjusts motor turn and torque when the motor is subjected to different load effects, and utilizes A stop mechanism, when the user releases the trigger button, causes a short circuit, so that the motor stops rotating immediately to avoid a dangerous situation. Therefore, in order to achieve the above purpose, the inventor of the present invention proposed a modification [S] 6 201115605 The switch of the switch is used to control one of the electric machine tools. The switch with a modified version includes a plate machine; the sliding mechanism is connected to the trigger button when the plate machine is pressed. The sliding mechanism will move in the opposite direction to the trigger-connecting end; „the first switching shaft, through (4) - the 帛 contact can switch the motor to start at the initial speed; the second switching shaft through the second switch The second contact of the shaft can switch the motor to run at full speed; a negative connection of the power source is connected at one end to an external DC power supply negative pole.
