The structure of the 2T scissor jack: A base, a pair of lower support arms, a pair of upper support arms, a saddle, a plane bearing, a nut, a cradle, a pin shaft, and a screw rod, and a pair of upper support arms have inner edges turned into ribs, and the ends thereof become gears Engaging and meshing, the sides of the pair of lower support arms are turned into ribs, and the ends are geared and meshed.
The principle of 2T scissor jack:
2T scissor jack are based on the geometric principle of isosceles triangles where the two waists do not change and the bottom edge raises the height. It uses the screw and nut to adjust the bottom edge of the upper and lower isosceles triangles to raise and lower the height. Just like the tool ladder in daily life, the smaller the angle between the two arms of the ladder is, the higher the ladder is. Similarly, the larger the angle between the arms of the ladder is, the lower the ladder is.
2T Scissor jack, also known as stand jack, are quick and easy to use, and are truck-mounted products in major domestic auto factories. The upper and lower struts are made of sheet metal. The cross-sections of the upper struts and the lower struts in the tooth portions and in the vicinity thereof are rectangular with one side open, and the metal plates on both sides of the openings 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 greater than the thickness of the metal plate.
The use of 2T scissors jack:
Suitable for mechanical maintenance, especially car maintenance, stable and reliable, carrying capacity. Since 2T scissor jack are mechanical jack, you don't need to worry about oil leakage.
