[0002] The clutch master cylinder, also known as the clutch master cylinder, is the main type of clutch hydraulic operating system.

[0030] like Figure 1 and Figure 2 As shown, the clutch master cylinder sensor automatic detection device with sensor includes:

[0031] The push rod positioning mechanism 1 comprises a push rod transverse sliding plate assembly, a push rod fixing seat 1.4 connected to the push rod transverse sliding plate assembly, and a push rod pressing cylinder 1.3.
