A sliding groove 22 is formed on the surface of main rod 21. A hand screw 23 is movably installed on the inner side of sliding groove 22 through a bearing. Two groups of lifting frames 24 are slidably installed on the inner side of sliding groove 22. Rubber rollers 25 are rotatably installed at the ends of lifting frames 24. A rubber turntable 26 is rotatably installed on the middle surface of main rod 21. By arranging two groups of rubber rollers 25 that can approach each other, the rubber rollers 25 can be clamped on the outer side of the end of roller body 1. When the scale rod 35 is located at a position outside roller body 1, the rubber rollers 25 can also roll on the end of roller body 1. This can make the scale rod 35 stably rotate around the axis of roller body 1, avoid the position deviation of detection probe 36, and cause the detection position to deviate, which affects the detection result.

[0028] Positioning structure 2 is provided with detection structure 3, and detection structure 3 includes fixed block 31, which is fixedly installed on the middle part of the side wall of main rod 21. A movable block 32 is sleeved on the end of fixed block 31. A spring 33 is fixedly connected to the inner wall of movable block 32. A slot 34 is formed on the surface of movable block 32. A scale rod 35 is inserted into the inner side of slot 34. A detection probe 36 is installed at the end of scale rod 35. A positioning bolt 37 is threadedly connected to the surface of movable block 32.

[0029] Further, the hand screw 23 penetrates through the two groups of lifting frames 24 and is threadedly connected with the two groups of lifting frames 24. The rotation of hand screw 23 can drive the two groups of lifting frames 24 to move towards each other, so as to realize the mutual approach or separation of the two groups of rubber rollers 25 outside roller body 1.

[0030] Further, two groups of lifting frames 24 are located on both sides of the roller body 1, and the two groups of rubber rollers 25 are attached to the outer wall of the roller body 1. The two groups of rubber rollers 25 provide limiting for the installation of the positioning structure 2 on the roller body 1. The rubber rollers 25 can roll on the roller body 1.
