Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Please refer to FIG. 1 to FIG. 4 , the present utility model provides a technical solution: a tower ruler for elevation measurement, comprising a tower ruler body 1, and a pulling block 2 is fixed on the tower ruler body 1 (which can be welded on the tower ruler body). 1, it can also be fixed on the tower ruler body 1 by means of a screw, if you want to facilitate disassembly, use a screw to fix), the inner wall of the pulling block 2 is provided with a cross bar 3, the cross bar 3 is arranged through the outriggers 4, and the outriggers The top surface of 4 is provided with a positioning hole 5, the interior of the positioning hole 5 is inserted with a first locking screw 6, the first locking screw 6 is screwed on the top surface of the pulling block 2, and the first locking screw 6 is screwed upwards. Disengage the first locking screw 6 from the positioning hole 5, and then rotate the outrigger 4 around the cross bar 3. When the outrigger 4 is in contact with the inclined surface inside the pulling block 2, screw the first locking screw 6 downward to make the first locking screw 6. A locking screw 6 is screwed into another positioning hole 5;

A telescopic groove 7 is formed on the bottom surface of the outrigger 4, and a telescopic connecting rod 8 is inserted into the interior of the telescopic groove 7. A locking hole 9 is opened on the surface of the telescopic connecting rod 8, and a second locking screw 10 is inserted into the inside of the locking hole 9. The second locking screw 10 is screwed on the surface of the outrigger 4, the end of the telescopic link 8 is welded with a connecting seat 11, the surface of the connecting seat 11 is welded with a universal wheel 12, and the second locking screw 10 is screwed to the outside, Then, the telescopic link 8 is stretched out along the telescopic slot 7.
