[0037] A thread groove 104 is provided at the top of the measuring rod 103, and the bottom end of the rotating shaft of the motor 108 passes through the interior of the thread groove 104 and is fixedly connected to a round block 105. An external thread is provided on the outer wall of the round block 105 and is threadably matched with the thread groove 104. A center-shaped groove 106 is provided on the front side of the connecting plate 101, and a sliding member 107 is rotatably connected to the interior of the vertical groove of the center-shaped groove 106.

[0038] The sliding member 107 includes a center-shaped block 107a, the side surfaces of the two horizontal blocks of the center-shaped block 107a are respectively slidably connected to the inside of the two horizontal grooves of the center-shaped groove 106, the rear side of the vertical block of the center-shaped block 107a and the upper side of the front side of the measuring rod 103 are fixedly connected with a rack 107b, the inside of the vertical groove of the center-shaped groove 106 is rotatably connected with a gear 107c, the gear 107c is respectively engaged with the two racks 107b, and by moving the front rack 107b upward, the measuring ruler 101a can be driven to move upward to measure the road thickness.

The four slide grooves 202 are grouped into two and are respectively provided on the front and rear sides of the inner walls of the two support plates 201. The angle between the slide grooves 202 in a group of two is 160°. When two round rods 203 slide inside the inclined slide grooves 202 in a group of two, the support member 204 can be driven to move downward. The slide groove 202 is slidably connected with the round rod 203 inside. A long groove 208 is provided inside the round rod 203.
