Therefore, when measuring an object, the tool microscope is most commonly used. When the tool microscope is in use, it will be used in conjunction with a measuring table. Therefore, a tool microscope measuring table needs to be set up.

[0003] The carburetor can be said to be the heart of the engine. The carburetor can well provide the engine with a mixture. The performance of the engine is determined by itself. The carburetor cannot improve the ability of the engine itself, but it can play a role in making the engine exert its maximum function. The carburetor has been replaced by electronic fuel injection technology in automobiles and high-end motorcycles, but it is still widely used in equipment such as mid-range and low-end motorcycles and general engines. The advantages of the carburetor are simple structure and small volume.

[0004] In the prior art, in order to test whether a carburetor is qualified, the carburetor is detected by a tool microscope. And since the existing carburetors are all provided with air flow channels, and the inner circles at both ends of the air flow channels are mostly standard circles, in order to improve the detection speed, a tool microscope dedicated to carburetor detection needs to be designed.
