[Abstract]:
Leo Trading Co., Ltd. introduced that the scissor jack is one of the jacks and a lifting device, 
  Leo Trading Co., Ltd. introduced that the scissor jack is one of the jacks and a lifting device, which is mainly used for jacking and supporting of small tonnage cars such as cars. Common specifications are 1T (ton), 1.5T (ton), 2T (ton), 3T (ton) and so on.
  In general, the scissor jack is also called the bracket jack, which is light and fast, and is a car-mounted product of major automobile factories in China. It consists of an upper strut and a lower strut made of sheet metal, and the working principle is different. The cross section of the upper strut and the cross section of the lower strut at the tooth portion and its vicinity are rectangular with one side open, and the metal plates on both sides of the opening are bent inward. The teeth on the upper and lower struts are made of metal plates bent on both sides of the opening, and the tooth width is larger than the thickness of the metal plate.
  The scissor jack is based on the geometric principle of the isosceles triangle and the two waists that shorten the bottom edge and raise the high line. It adjusts the bottom and bottom of the upper and lower isosceles triangles by screw and nut to raise and lower the height. Just like the tool ladder in normal life, the smaller the angle between the arms of the ladder, the higher the ladder. The larger the angle between the arms of the same ladder, the lower the ladder.
  It is mainly suitable for mechanical maintenance, especially for car maintenance, stable and reliable, and has large carrying capacity. Since the scissor jack is a mechanical jack, you don't have to worry about oil leakage. You can also use it horizontally.
