[0028] The expansion mechanism includes an expansion ruler 2, which is installed on the surface of the ruler body 1. An insertion groove 21 is provided inside the ruler body 1. An insertion plate 22 is fixedly connected to the surface of the expansion ruler 2. A screw hole 23 is provided on the surface of the insertion plate 22. A groove 24 is provided on the surface of the ruler body 1. An insertion hole 25 is provided inside the ruler body 1. A connecting screw 26 is installed on the surface of the groove 24. Under the action of the expansion ruler 2, the length of the ruler body 1 is expanded, so that the measuring range is increased, and the scale value on the expansion ruler 2 continues to be set along the scale value of the ruler body 1. The expansion ruler 2 and the ruler body 1 are tightly connected after installation to reduce errors.

[0029] Furthermore, the extended ruler 2 is connected to the surface of the ruler body 1, the size of the insertion groove 21 is larger than the size of the insertion plate 22, the insertion plate 22 is plugged and connected to the surface of the insertion groove 21, and two groups of screw holes 23 are provided. The two groups of screw holes 23 are opened on both sides of the insertion plate 22. Under the connection between the insertion groove 21 and the insertion plate 22, the ruler body 1 and the extended ruler 2 are connected. At the same time, the distance between the centers of the two groups of screw holes 23 is the same as the distance between the centers of the two groups of insertion holes 25.

[0030] Furthermore, two groups of grooves 24 and plug-in holes 25 are provided, the diameter of the grooves 24 is larger than the diameter of the plug-in holes 25, and the connecting screws 26 pass through the grooves 24 and the plug-in holes 25 and are connected to the surface of the ruler body 1.

The connecting screws 26 are plugged and connected to the surface of the plug-in holes 25.

[0031] Furthermore, one end of the connecting screw 26 is connected to the surface of the screw hole 23 through a thread, and the other end of the connecting screw 26 is abutted against the surface of the groove 24. Under the connection between the connecting screw 26 and the screw hole 23, the plug-in plate 22 can be fixed on the surface of the plug-in groove 21 and abut against it, so as to limit the extension ruler 2, thereby achieving the expansion of the length of the ruler body 1, so that the measuring range of the tool for the flange is increased.

[0032] Furthermore, a pressing mechanism is provided on the surface of the outer measuring claw 11, and the pressing mechanism includes a contact plate 3, which is installed on the surface of the outer measuring claw 11, and a connecting plate 31 is fixedly connected to the surface of the contact plate 3, a plug-in block 32 is fixedly connected to one side of the connecting plate 31, and a sleeve 33 is fixedly connected to the other side of the connecting plate 31, and a connecting hole 34 is opened on the surface of the outer measuring claw 11.

[0033] Furthermore, two groups of abutment plates 3 are provided, each group of abutment plates 3 has two abutment plates 3, and each group of abutment plates 3 is fixedly connected to both sides of the connecting plate 31. The cross-section of the connecting plate 31 is "U"-shaped, and the connecting plate 31 is snap-connected to the surface of the outer measuring claw 11. When the tool measures the outer ring of the flange, the abutment plate 3 can contact its surface without slipping, so as to avoid inaccurate measurement. The plug-in block 32 and the sleeve 33 can be installed on the surface of the connecting hole 34 by bending the connecting plate 31.

[0034] Furthermore, the plug-in block 32 and the sleeve 33 are plug-connected on the surface of the connecting hole 34. One side of the plug-in block 32 is cylindrically installed on the surface of the connecting plate 31, and the other side of the plug-in block 32 is spherically plug-connected on the surface of the sleeve 33.

[0035] Working principle: When using this tool to detect the flange, first install the extension ruler 2 at one end of the ruler body 1, and insert the plug-in plate 22 into the plug-in groove 21 and engage with its top end. At this time, the two sets of screw holes 23 and the plug-in holes 25 are aligned, and then the connecting screws 26 are inserted into the plug-in holes 25 and connected with the screw holes 23 through the action of the thread. Finally, the connecting screws 26 are engaged with the surface of the groove 24 and the outermost side is kept flush with the outer surface of the ruler body 1, thereby completing the expansion of the length of the ruler body 1.

[0036] When measuring the outside of the flange, since the outside is arc-shaped, the pressing mechanism needs to be installed on the outer measuring claw 11. First, the connecting plate 31 is bent to make it engage with the outer measuring claw 11, and the plug-in block 32 and the sleeve 33 can be inserted into the connecting hole 34, and the two sides of the connecting plate 31 are pressed so that the plug-in block 32 is inserted into the sleeve 33. At this time, the outer measuring claw 11 can be pressed against the outer ring during detection, and the pressing plates 3 on both sides also press against the outer ring and generate a certain friction force to prevent the outer measuring claw 11 from sliding during measurement.
