[0019] A rotating rod 2 is rotatably penetrated through the top of the base plate 1, and a first gear 21 is fixedly sleeved on the outer side of the rotating rod 2. The top of the first gear 21 is meshedly connected with a second gear 22, and the bottom of the second gear 22 penetrates the top of the base plate 1. A rotating shaft 23 is fixedly penetrated through the middle of the second gear 22. A symmetrically distributed connecting block 24 is fixedly installed on the bottom end of the support plate 11, and the connecting block 24 is fixedly sleeved on the outer side of the rotating shaft 23. A mounting plate 25 is fixedly installed on the side of the support plate 11 away from the movable rod 15, and a level 26 is fixedly installed on the top of the mounting plate 25.

[0020] The top of the bottom plate 1 is fixedly mounted with symmetrically distributed stabilizing blocks 3, and the rotating shaft 23 rotates through the stabilizing blocks 3. By providing the stabilizing blocks 3, the rotating shaft 23 can be supported so as to be able to rotate.

[0021] A driving rod 4 is rotated and penetrated on one side of the base plate 1 away from the rotating rod 2. A worm 41 is fixedly installed on one end of the driving rod 4 away from the inner wall of the base plate 1. The top of the worm 41 is meshed and connected with a worm wheel 42. The worm wheel 42 is fixedly sleeved on the outer side of the rotating rod 2. By rotating the driving rod 4, the worm 41 is driven to rotate, and the worm 41 drives the worm wheel 42 to rotate, thereby driving the rotating rod 2 to rotate. The worm 41 and the worm wheel 42 can self-lock the driving rod 4 to prevent the rotating rod 2 from rotating after the adjustment is completed.

[0022] The limiting rods 5 are fixedly installed on the opposite sides of the two fixing plates 17. The limiting rods 5 pass through the two clamping plates 19. By setting the limiting rods 5, the clamping plates 19 can be limited to avoid displacement during movement and improve their stability.

[0023] The top movable sleeve of the movable rod 15 is provided with a movable frame 6, and a cleaning cloth 61 is fixedly installed on the inner wall of the movable frame 6. The cleaning cloth 61 is in contact with the movable rod 15. By moving the movable frame 6, the cleaning cloth 61 is driven to move, so that it can remove the marks on the surface of the movable rod 15, which is convenient for use.

[0024] A fixing hole 7 is opened at the top of the movable frame 6, and a pin 71 is detachably inserted in the fixing hole 7. The pin 71 passes through the top of the movable rod 15. By passing the pin 71 through the fixing hole 7 and the top of the movable rod 15, the movable frame 6 can be fixed. When it is needed, the pin 71 is taken out to improve the user experience of the staff.

[0025] A stabilizing plate 8 is fixedly installed on opposite sides of the inner wall of the hollow groove 12. The middle part of the stabilizing plate 8 is distributed in a circular state. The output end of the electric push rod 13 passes through the stabilizing plate 8.

[0026] Working principle: In actual use, the base plate 1 is placed in a suitable position, the measuring ball 16 is brought into contact with the ground, and then the marker pen is placed between the two clamping plates 19, and the output end of the marker pen is brought into contact with the scale on the movable rod 15. By driving the double-headed screw 18 to rotate, the two clamping plates 19 are driven to approach each other until the marker pen is fixed. By driving the electric push rod 13, its output end drives the bracket 14 and the movable rod 15 to move. When the movable rod 15 encounters a raised or sunken ground, the movable rod 15 moves up or down under the limit of the bracket 14. The worker moves down, and the marking pen marks the surface of the movable rod 15. When the measurement is completed, the staff can obtain the required data by checking the length of the line segment; the staff uses the level 26 to observe whether the base plate 1 is in a horizontal state. When adjustment is needed, the first gear 21 is driven to rotate by driving the rotating rod 2, the first gear 21 drives the second gear 22 to rotate, the second gear 22 drives the rotating shaft 23 to rotate, and the rotating shaft 23 drives the supporting plate 11 to rotate through the connecting block 24, so that the angle of the movable rod 15 can be adjusted to keep it vertical to the ground.

[0027] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
