[0038] Reference Figure 3 - Figure 5 The bolt 51 passes through and is threadedly connected to the right surface of the slider 31, one end of the compression spring 52 is fixedly connected to the left surface of the positioning ring 53, and the other end of the compression spring 52 is fixedly connected to the inner wall of the left side of the slider 31. When the positioning ring 53 moves to the left, it squeezes the compression spring 52 to generate a reaction force, and the positioning ring 53 is slidably connected to the inner wall of the slider 31.

[0039] Reference Figure 3 - Figure 5The positioning block 54 is inserted into the inner wall of the positioning groove 501. The positioning groove 501 is opened in an arc shape. The right surface of the positioning block 54 is set as an arc surface. By squeezing the arc surface of the positioning block 54, the positioning block 54 will move and squeeze the compression spring 52 to generate a reaction force.

[0040] Reference Figure 4 - Figure 6 There are multiple groups of anti-loosening components, which are evenly distributed on the slider 31, the mounting plate 32, and the mounting block 33. The anti-loosening components on the mounting plate 32 and the mounting block 33 are placed in the front-to-back direction. When the bolts 51 on the slider 31 are tightened, the slider 31, the bracket 2 and the mounting plate 1 will be tightly attached together, and the device will remain stable under the influence of friction.

[0041] Working principle: When the device is used, firstly, the bolts 51 are screwed on the slider 31, the mounting plate 32 and the mounting block 33, so that the mounting plate 1, the bracket 2, the slider 31, the mounting plate 32 and the mounting block 33 are connected to each other, and then the bracket 2 is moved longitudinally to a suitable height. When it is moved to a suitable height, the bolts 51 used to connect the mounting plate 1, the slider 31 and the bracket 2 are tightened to fix the mounting plate 1, the slider 31 and the bracket 2 together, and then the mounting plate 32 is moved horizontally. When the mounting plate 32 is moved to a suitable position, the bolts 51 used to connect the mounting plate 32 and the bracket 2 are tightened, and the mounting plate 32 is moved horizontally. The nut 55 on its outer wall is tightened to fix the mounting plate 32 and the slider 31. Finally, the dial indicator body 4 is inserted into the round hole. The mounting block 33 is then adjusted to a suitable position, and the bolts 51 used to connect the mounting block 33 and the mounting plate 32 are tightened. The nut 55 on its outer wall is tightened to fix the mounting block 33 and the mounting plate 32. At this time, the dial indicator body 4 will also be fixed on the mounting block 33. At this time, the accuracy of the workpiece can be measured. The two dial indicator bodies 4 in different directions can measure the horizontal and longitudinal accuracy of the workpiece at the same time.

[0042] When the bolt 51 is tightened, the positioning block 54 will be inserted into the positioning groove 501 to limit the bolt 51. When the bolt 51 is slightly reversed, it will squeeze the arc surface of the positioning block 54. The squeezing of the positioning block 54 will drive the positioning ring 53 to move and squeeze the compression spring 52 to generate a reaction force. Then, under the influence of the reaction force of the compression spring 52, the positioning ring 53 and the positioning block 54 will be pushed to reset. During the resetting process of the positioning block 54, the positioning groove 501 will be squeezed to drive the bolt 51 to rotate, so that the bolt 51 is tightened, thereby ensuring the stability of the device.
