The gear 7 is located on both sides of the adjusting column 3. By setting the gear ring 11, the rotating rod 4 can be gently pushed to be firmly placed on the surface of the adjusting column 3 to facilitate the fixation of the gear 7 at different angles.

[0025] See also Figure 1 and Figure 2 The quantitative mechanism 6 includes an adjusting rod 12, which passes through the top of the adjusting column 3. A screw 13 is provided on the surface of the adjusting column 3. Measuring marks 14 are respectively embedded and installed on the surfaces of the adjusting column 3 and the adjusting rod 12.
