At present, the commonly used is the scissor jack. The scissor jack is famous for its simple structure and easy to carry. It uses the horizontal screw transmission to form its own structural deformation, so as to achieve the lifting effect. However, the lifting height of the scissor jack is seriously limited, and the chassis is not robust, so it is usually used in cars with low chassis.

The vertical hydraulic jack is also widely used. It uses the hydraulic transmission principle, which makes it easier and convenient to operate. Compared with the scissor jack, the lifting height is higher and the chassis is more stable. It is usually used for some trucks and off-road vehicles with higher chassis.

Another kind of vehicle jack is horizontal jack, which is also a kind of hydraulic jack. Its biggest feature is that it is safe and stable. Because it is horizontal, we don't have to worry about chassis problems and dumping problems at all, and its lifting height is also excellent. It is usually common in some automobile repair plants and can be used for the maintenance of various vehicles. The only drawback is that the price is higher.
