[0027] According to this specific embodiment, the base 101 is used to install the measuring component 102 .

[0028] Among them, the two sliders 103 are respectively slidably connected to the base 101 and are respectively located inside the base 101; the double-threaded screw 104 is rotatably connected to the base 101 and is respectively threadedly connected to the two sliders 103 and passes through the two sliders 103 respectively; the two limit frames 105 are respectively fixedly connected to the two sliders 103 and pass through the base 101 respectively; the positioning rod 106 is fixedly connected to the base 101 and is located at the top of the base 101; the moving block 107 is slidably connected to the base 101 and is located inside the base 101; the pushing mechanism 108 is arranged on one side of the moving block 107; the measuring rod 109 is fixedly connected to the moving block 107 and passes through the base 101; the connecting rod 110 is fixedly connected to the moving block 107 and passes through the base 101; the pointer 111 is fixedly connected to the connecting rod 110 and is located on one side of the connecting rod 110. The double-threaded screw 104 is divided into two left and right sections, and the thread directions of the two sections are opposite. Rotating the double-threaded screw 104 can drive the two sliders 103 to slide in opposite directions, and the two sliders 103 drive the two limit frames 105 to move synchronously in opposite directions. The pushing mechanism 108 is used to move the moving block 107. The movement of the moving block 107 drives the measuring rod 109 to move, and also drives the pointer 111 to move through the connecting rod 110.

At this time, the center of the pipe cap, the center of the cross-section of the positioning rod 106 and the center of the cross-section of the measuring rod 109 are in the same vertical plane, and then the push rod 116 is pushed to push the moving block 107 to drive the measuring rod 109 to move right, until the positioning rod 106 and the measuring rod 109 are respectively against the left and right sides of the inner wall of the pipe cap, and then the reading can be directly read according to the scale line 113 and the pointer 111.
