[0002] Raised pavement markers, generally referring to road studs, are a common type of traffic barrier used to guide people to travel in the correct direction, prevent speeding and traffic accidents, and are mainly used on highways and railways. To make them more conspicuous and have better reflective effects, they are often inlaid with reflective lattice sheets or covered with reflective film. To ensure driving safety, raised pavement markers need to be inspected before use, usually using a raised pavement marker measuring instrument. Existing raised pavement marker measuring instruments require the marker to be placed on an adjustment plate, the plate manually rotated to adjust the detection angle, and then the measuring instrument closed. Each adjustment and calibration requires lifting the measuring instrument for adjustment and then closing it again, severely impacting detection efficiency.

The second moving groove meshes with the rack 5; the inner diameter of the second moving groove matches the docking rod 14; the middle part of the docking rod 14 is slidably disposed in the second moving groove; a spring 16 is sleeved in the middle part of the docking rod 14, one end of the spring 16 abuts against the step of the docking rod 14, and the other end abuts against the side wall of the second moving groove; the push rod 15 is connected to the docking rod 14 at one end in a laterally concave shape, the docking rod 14 is disposed in the middle gap, the docking rod 14 is provided with an inclined third sliding groove 17, and a sliding rod 18 is provided at the connecting part to pass through the push rod 15 and the third sliding groove 17 vertically, and the sliding rod 18 slides in the third sliding groove 17. Pressing the push rod 15 causes the slide rod 18 to slide within the third slide groove 17, thereby retracting the connecting rod 14 and compressing the spring 16. At this point, the rod is in a relaxed state, allowing the pull-out plate 3 to move. After moving, releasing the push rod 15 causes the connecting rod 14 to advance due to the spring 16. One end of the connecting rod 14 engages with the rack 5, fixing the pull-out plate 3 in place. The movable design of the pull-out plate 3 avoids frequent lifting of the measuring instrument during measurement, greatly reducing manpower consumption. The push rod 15's push-button design also makes operation more convenient. A lever is also provided on the outside of the pull-out plate 3 for pulling it out, which can also provide leverage for the push rod 15's movement.
