Automatic Nut Tightening Fixture

This mechanism is used for automatically tightening nuts such as those for car lights. It uses a stepper motor with a right-angle reducer to automatically screw in the nuts. To overcome the above-mentioned shortcomings of the existing technology, this mechanism provides an assembly structure for the car light body and the installation of nuts on the car light body. It facilitates blind installation of the nuts and prevents improper installation of the nuts.
