[0002] When using a machine vision recognition device to observe and recognize different devices, different devices need to be placed at fixed positions to improve the recognition speed and work efficiency. The traditional positioning method for the device to be inspected usually uses a special fixture for positioning. The special fixture made by this method has a high production cost and is time-consuming and laborious to disassemble.

[0003] For example, a center point positioning base of a machine vision experimental table for teaching with a patent application number of 202020497861.6. This patent uses a connecting rod assembly to realize the symmetrical movement of the transverse and longitudinal baffle assemblies, and finally the experimental observation device is pushed to the middle position of the experimental table. Although the experimental observation device can be pushed to the middle position of the experimental table through the above movement method, it does not have the function of rapid limiting, is easy to cause the object to be measured to move, and there is a large deviation in positioning when the transverse and longitudinal baffle assemblies are linked by the connecting rod assembly, and it is less durable.
