In education and teaching, the plastic toolbox has the following applications:
1. laboratory teaching
      Chemical laboratory: a small plastic toolbox used to store various glass instruments, such as test tubes, beakers, measuring cylinders, etc., to prevent collision damage of instruments. It can also store tweezers, droppers and other small tools for students' convenience.
      Physics Laboratory: small measuring tools such as weights, spring dynamometers, ammeters, voltmeters and so on can be classified and stored in different plastic toolboxes, which is convenient for the preparation before and after the experiment, and improves the efficiency of the experiment.
      Biological laboratory: store the eyepiece, objective lens, slide, cover glass and other accessories of the microscope. It can also be used to place anatomical tools such as dissecting needles and tweezers to keep the experimental equipment in order.
2. handicraft and art teaching
      Manual class: store scissors, glue, colored paper, origami, manual rope and other manual materials and tools to facilitate students' access at any time in the process of manual production, and cultivate students' practical ability and creativity.
      Art class: it can be used to place painting tools such as paintbrushes, pigments, color palettes and knives, and also to store some small sculpture tools and materials, such as clay and carving knives, which will help students better carry out artistic creation.
3. science and technology and Engineering Education
      Robot teaching: store screws, nuts, gears, motors and other parts required for robot assembly, as well as assembly tools such as screwdrivers and wrenches, so that students can quickly find the required parts when assembling and debugging robots, and cultivate students' engineering practice ability and logical thinking ability.
      Teaching of electronic production: it is used to store electronic components, such as resistors, capacitors, diodes, integrated circuits, etc., as well as electronic production tools such as electric soldering irons and multimeter, so as to help students better manage and use these equipment and improve the learning effect when learning electronic circuit knowledge and carrying out practical operation.
      General technology teaching: store all kinds of general tools, such as saws, files, hammers, nails, etc. students can use tools from the plastic toolbox when making simple woodworking and metalworking, so as to cultivate students' technical literacy and practical operation ability.
      The use of plastic toolbox can not only improve teaching efficiency, cultivate students' good habits, but also ensure the safe and orderly teaching activities.
