The working principle of the specific embodiment is as follows: when the device is used, the fixed support 4 is pushed to drive the driving wheel 3 at the bottom to push, the measuring block 5 is moved to a position to be detected, the driving motor 6 is started to enable the rotating worm 8 to rotate, the rotating worm wheel 9 is meshed to drive the rotating worm wheel 9 to rotate, the rotating fulcrum shaft 10 drives the rotating screw rod 11 to rotate, then the driving fulcrum block 12 is enabled to move in height, the measuring block 5 is enabled to move in height, and the road surface is subjected to leveling detection operation through the measuring block 5; in the detection process, if a sunk part is found on the road surface, the movable motor 16 is started to drive the movable screw rod 17 to rotate, the movable block 18 is made to move, the marking pen 20 is made to move to the upper side of one side of the sunk part, the pushing cylinder 13 is started to push downwards, the pushing frame 15 is driven to move downwards, the supporting frame 14 is made to move downwards until the marking pen 20 is in contact with the road surface, the movable motor 16 is started again, the marking pen 20 performs marking operation on the road surface, marking is performed, and the size of the observed mark can be found according to the numerical value of the surface of the measuring block 5; similarly, when the other side of the depression needs to be marked, the marking operation can be performed only by moving the marker 20 to the required place; when the marker 20 is not needed to be used, the pushing cylinder 13 pushes upwards to drive the marker 20 to move upwards, the electric push rod 21 pushes the inserting block 22 to move until the marker is inserted into the slot 5-4, and the inserting block 22 limits the marker 20 so as to prevent the marker 20 from contacting with the road surface in the detection process; according to the different angles of subsidence, the rotating seat 1-2 is driven to rotate by starting the rotating motor 2, the fixed support 4 and the measuring block 5 are driven to rotate, the measuring angle of the measuring block 5 is changed, and the actual operation is more convenient.

After adopting above-mentioned structure, this embodiment beneficial effect does:

1. the driving support block 12 is driven to move up and down to drive the measuring block 5 to carry out leveling detection operation on the road surface;

2. the marking pen 20 is moved to a proper position by driving the moving block 18 to move, the marking pen 20 is driven to move downwards by the pushing cylinder 13 to be in contact with the road surface, and finally the marking pen 20 is driven to mark the road surface;

3. the angle of the measuring block 5 and thus the mark drawn by the marker pen 20 is changed by rotating the rotary base 1-2.

The above description is only for the purpose of illustrating the technical solutions of the present invention and not for the purpose of limiting the same, and other modifications or equivalent substitutions made by those skilled in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
