Problems solved by technology

[0002] At present, with the rapid development of industrial technology, the requirements for mechanical automation are getting higher and higher, and the structure of mechanical automation is becoming more and more complex. The design of complex mechanical structures not only brings about the increasing volume of equipment, but also The cost is also increasing, seriously affecting the widespread application of mechanical automation equipment
[0003] For example, cylinders are often used to drive the displacement of components. In order to meet the requirements of large displacement, they can be replaced with large-stroke cylinders. However, the cylinder body of large-stroke cylinders is long and requires a large installation space, which is fundamental for equipment with limited installation space. It is impossible to install a large-stroke cylinder, and if a small-stroke cylinder is installed, it cannot meet the requirements of its stroke
Therefore, when the stroke of the driving component is required, the existing automation equipment cannot meet the requirements of some existing automation equipment with limited installation space because the structure of the control stroke is too complicated or the space occupied is too large.
[0004] At present, there is a rack and pinion structure, which can achieve the effect of multiple displacement, but the scope of application of this fixed range-extended structure is very limited, because in most cases, the required displacement and the original displacement that can be provided are difficult to coincidentally.
