Everyone should be very familiar with the scissor jack. The scissor jack is a type of jack commonly used by car owners, known for its simple structure, affordable price, and easy portability. Its design can be said to be simpler than any type of jack. However, this type of jack has three mechanical principles synchronized during operation.

The lifting principle of scissor type structure: This is a special appearance structure that is exactly opposite to the stability of a triangle. Under external force, the entire scissor type structure is very prone to deformation. This deformation will cause the distance between two pairs of diagonal points to increase and decrease respectively. The added points are the vertices, and the process of increase is the process of lifting.

Spiral transmission principle: Even if it is not a traditional spiral jack, it is still driven by the spiral transmission of the screw. The scissor jack has a screw between two horizontal diagonals, and the change of the scissor structure is controlled by the lateral transmission of the screw. The entire transmission process controls the deformation of the scissor structure.

Leverage principle: One of the most well-known physical principles, the scissor jack, whether it is a joystick or a wrench, undoubtedly utilizes the principle of a labor-saving lever. It is driven by a joystick or wrench to advance the rotation and transmission of the screw. Whether it is a swinging or pulling driving method, the role of the labor-saving lever is maximized.

These are the three principles exhibited by the scissor jack during operation. If you want to learn more about the hardcore knowledge of scissor jacks, you can always follow us.
