By designing the groove 84, the pressure rod 82 can slide along the limit block 83. The limit block 83 is slidably connected to the connecting seat 3 and the rotating shaft. 5. A sliding connection is provided. A guide rod 85 is fixedly connected to the outer side of the limiting block 83. The guide rod 85 is slidably connected to the connecting seat 3. A first spring 86 is provided on the outer side of the guide rod 85. One end of the first spring 86 is fixedly connected to the connecting seat 3, and the other end of the first spring 86 is fixedly connected to the limiting block 83. By designing the first spring 86, the force of the first spring 86 can be applied to the limiting block 83. A magnetic seat 87 is provided inside the connecting seat 3. By designing the connecting mechanism 8, it is convenient to disassemble the rotating shaft 5.

[0023] Please see Figure 1 , Figure 2 , Figure 4 The adjusting mechanism 9 includes a slot 91. The connecting seat 3 has a slot 91 inside. A ball 92 is movably fitted inside the slot 91. There are multiple slots 91, which are evenly distributed inside the connecting seat 3. By designing multiple slots 91, the ball 92 can roll into the slots 91 at different positions. The ball 92 is slidably connected to the dovetail block 4. A slider 93 is movably fitted outside the ball 92. The slider 93 is slidably connected to the dovetail block 4.

[0024] The specific implementation process of this utility model is as follows: In use, through the function of bearing 6, the probe and the object being measured form point-to-point contact to eliminate the friction between the probe and the object being measured. At the same time, bearing 6 can eliminate the force generated in the measurement direction, thereby improving the performance of the probe.

[0025] When it is necessary to disassemble the bearing 6, push the push-pull rod 81 downwards. The push-pull rod 81 drives the pressure rod 82 to move downwards.

The limiting block 83 will be squeezed and move horizontally. The limiting block 83 can drive the guide rod 85 to move horizontally. The limiting block 83 can squeeze the first spring 86. When the push-pull rod 81 is attracted to the magnetic seat 87, the limiting block 83 will slide out from the inside of the rotating shaft 5. Then the rotating shaft 5 can be pulled out from the inside of the connecting seat 3, which facilitates the disassembly of the rotating shaft 5 and the bearing 6 structure, and facilitates the inspection and maintenance of the bearing 6 structure.

[0026] When the relative position of the connecting seat 3 and the fixed plate 1 needs to be adjusted, the connecting seat 3 is directly pushed horizontally. The connecting seat 3 and the dovetail block 4 slide relative to each other. The arc surface of the slot 91 inside the connecting seat 3 will squeeze and push the ball 92 to roll into the dovetail block 4. The ball 92 will drive the slider 93 to move. The slider 93 can squeeze the ball 94. At the same time, the slider 93 will slide along the fixed rod 95 to squeeze the second spring 96. Finally, the slot 91 and the ball 92 can be separated. As the connecting seat 3 moves, under the elastic action of the ball 94 and the second spring 96, the slider 93 will be pushed outward, which can push the ball 92 into the slot 91 in another position. At this time, the relative position of the connecting seat 3 and the fixed plate 1 can be adjusted and fixed, which makes it convenient to flexibly adjust the use position of the connecting seat 3 and the bearing 6 and improve the measurement adaptability.
