[0023] In this embodiment, the protective cover 4 is sleeved on the outer periphery of the tower ruler body 1 in a matching arrangement, and shrinkage grooves are opened near both sides of the bottom of the base 10. By placing the tower ruler body 1 in the protective cover 4, the protection of the tower ruler body 1 is improved.

[0024] In this embodiment, the door panel 7 is hingedly located in front of the protective cover 4 and is movably rotatable. The magnetic strip 9 at the rear of the door panel 7 and the magnetic strip 9 at the front of the protective cover 4 attract each other. By opening and closing the door panel 7, the scale on the front of the ruler body 1 is displayed for surveying and measurement.

[0025] In this embodiment, the screw 12 passes through the fixed block 11 and the base 10 and is threadedly connected. The universal wheel 15 is located at the bottom of the screw 12 through the bearing 14 and is movably rotatable. The universal wheel 15 is lifted and retracted by the screw 12 to facilitate the movement and placement of the tower ruler body 1.

[0026] In this embodiment, the fixing mechanism 3 includes four support rods 16, and the four support rods 16 are movably installed at the front and rear parts of the base 10 near the corners. A conical rod 17 is installed at the bottom of the support rod 16, and a fastening bolt 18 is movably installed through the front part of the support rod 16.
