Automobile toolbox is a kind of box container used to store automobile maintenance tools. It is mostly packed in blister box, which has the characteristics of small volume, light weight, easy carrying and easy storage. The car toolbox can be stored: air pump, flashlight, medical emergency bag, trailer rope, battery line, tire repair tools, inverter and other tools. These are necessary tools for motorists to drive. They can be put in the box for convenient use when driving. The role of tool kits on cars  Automobile toolbox is a kind of container used to store automobile maintenance tools. It is characterized by small volume, light weight, easy to carry and easy to store; Fire extinguisher, fire extinguisher vehicle fire extinguisher is a very important vehicle tool, but many car owners do not provide fire extinguishers for their cars, so they can't help when there is a danger.  Safety hammer: when the car owner encounters an emergency, if he needs to break the window, he should use the safety hammer to hit the four corners of the window, because the middle part of the toughened glass is the strongest. Usually, the car toolbox includes: trailer connecting ring, Jack, escape hammer, pulling rope, etc.  Jack refers to the light and small lifting equipment that uses the rigid lifting part as the working device to lift the heavy object through the small stroke of the top bracket or bottom claw. The jack is mainly used in factories, mines, transportation and other departments as vehicle repair and other lifting, support and other work. The structure is light, firm, flexible and reliable, and can be carried and operated by one person.  Jacks are divided into mechanical jacks and hydraulic jacks, with different principles. In principle, the most basic principle of hydraulic transmission is Pascal's law, that is, the pressure of liquid is the same everywhere. In this way, in the balanced system, the pressure applied on the smaller piston is relatively small, while the pressure applied on the larger piston is also relatively large, which can keep the liquid stationary. Therefore, through the transmission of liquid, different pressures on different ends can be obtained, and the purpose of transformation can be achieved.  The common hydraulic jack uses this principle to transfer force. The screw jack pulls the handle back and forth, pulls out the claw, that is, it pushes the ratchet clearance to rotate, and the small bevel gear drives the large bevel gear to rotate the lifting screw, so that the lifting sleeve can be lifted or lowered to achieve the function of lifting tension, but it is not as simple as the hydraulic jack.
