The inner ring 104 is fixedly connected, and each of the ball bearings 118 is rotatably connected to the anti-detachment ring 117. The anti-detachment ring 117 is fixedly connected to the base 101, the measuring head 121 is fixedly connected to the clamping block 120, the dial indicator 119 is fixedly connected to the clamping block 120, and the clamping block 120 is fixedly connected to the outer ring 103. The multiple ball bearings 118 in the rotating assembly 108 jointly support the outer ring 103 to facilitate the rotation of the outer ring 103 and the display assembly 109. With the anti-detachment ring 117 limiting each ball bearing 118, the outer ring 103 can rotate stably. This design is convenient to operate, easy to manufacture, and improves the detection efficiency of the measuring head 121 in the display assembly 109. It also solves the problem that the handle is not convenient for quickly adjusting the position of the base, and that rotating the handle easily causes the base 101 to rotate synchronously, affecting the measurement of the cylinder bore stop.
[0023] The display component 109 and the lifting component 106 are both located above the outer ring 103. The rotating component 108 is located inside the base 101. The positioning component 107 is located above the inner ring 104. The outer end of each connecting rib 105 is located inside the outer ring 103, and the inner end of each connecting rib 105 is located around the inner ring 104. The outer ring 103 is located above the base 101. The inner ring 104 is fixed by multiple connecting ribs 105 and provides installation support for the limiting part 113 so as to detect the depth inside the cylinder bore.
[0024] Secondly, the pull ring 112 is located at the upper end of the lifting rod 111, the lower end of the lifting rod 111 is located above the mounting plug 110, the mounting plug 110 is located above the outer ring 103, the positioning block 116 is located around the first positioning part 114, the first positioning part 114 is located at the lower end of the second positioning part 115, the upper end of the second positioning part 115 is located below the limiting part 113, the limiting part 113 is located above the inner ring 104, and multiple... The ball bearing 118 is designed to support the outer ring 103, while the outer ring 103 can also rotate freely on the base 101, improving the measurement efficiency of the measuring head 121 and the dial indicator 119. The pull ring 112 is manually pulled by the operator. Since the lifting rod 111 rotates with the mounting plug 110, the operator will not experience deformation of the rotation posture when pulling the outer ring 103, and the outer ring 103 can be stably driven to rotate, ensuring the detection of the measuring head 121.

The measuring head 121 is located below the clamping block 120, and the dial indicator 119 is located above the clamping block 120. The clamping block 120 is located above the outer ring 103. The measuring head 121 and the dial indicator 119 are directly connected and fixed above the outer ring 103 by the clamping block 120. When using this device, first, the positioning block 116 is inserted into the cylinder hole, and then the base 101 is placed outside the hole, keeping the base... After the base 101 is stabilized, the limiting part 113 is activated. The limiting part 113 drives the first positioning part 114, the second positioning part 115 and the positioning block 116 to probe into the hole. During this process, the operator manually pulls the pull ring 112, which drives the mounting plug 110 and the outer ring 103 to rotate above the base 101. The measuring head 121 also detects the stop around the hole to check whether the stop is continuous and flat. Since the outer ring 103 is also provided with a limiting ring on the outside, the outer ring 103 will not be pulled out of the base 101 when the pull ring 112 is pulled to rotate.
[0026] In this embodiment, the inner ring 104 is fixed by multiple connecting ribs 105 and provides installation support for the limiting part 113 to detect the depth inside the cylinder bore. The multiple ball bearings 118 facilitate support for the outer ring 103, while the outer ring 103 can also rotate freely on the base 101, improving the measurement efficiency of the measuring head 121 and the dial indicator 119. The pull ring 112 is manually pulled by the operator. Since the lifting rod 111 rotates with the mounting plug 110, the operator will not experience deformation of the rotation posture when pulling the outer ring 103, and can stably drive the outer ring 103 to rotate, ensuring the detection of the measuring head 121. The measuring head 121 is directly connected to the dial indicator 119 and is fixed by the clamping block 120. Above the outer ring 103, when using the device, firstly, the positioning block 116 is inserted into the cylinder hole, then the base 101 is placed outside the hole. After the base 101 is kept stable, the limiting part 113 is activated. The limiting part 113 drives the first positioning part 114, the second positioning part 115 and the positioning block 116 to probe into the hole. During this process, the operator manually pulls the pull ring 112, which drives the mounting plug 110 and the outer ring 103 to rotate above the base 101. The measuring head 121 also detects the stop around the hole to detect whether the stop is continuous and flat. Since the outer ring 103 is also provided with a limiting ring on the outside, when the pull ring 112 is pulled to drive the outer ring 103 to rotate, the outer ring 103 will not be pulled out of the base 101.
