[0003] At present, a Chinese utility model with announcement number CN213714117U discloses a straight thread quality rapid detection ruler, including a ruler and a slider. A serration structure is provided on one side end of the ruler. The tooth tip spacing of the serration structure is the spacing of the straight thread to be measured. The slider is slidably connected to the ruler. The utility model has a simple structure and is easy to operate. It can quickly detect the pitch, number of threads and thread length of the straight thread, thereby improving the detection efficiency of engineering inspection personnel.
[0004] In summary, the above improves the efficiency of detection, but there are still the following defects:
[0005] Firstly, the above-mentioned prior art cannot clamp the screw rod to be inspected during the bolt inspection process, and the screw rod is easily shaken by hand, resulting in inaccurate screw rod pitch measurement; secondly, when the above-mentioned prior art is in use, its slider wraps the front and back of the ruler, resulting in the ruler being unable to be placed horizontally in a balanced manner. If the slider and the ruler are to be placed in a balanced manner for measurement, it is necessary to separate the slider and the ruler, which is relatively troublesome, and the slider and the ruler are also easily lost when separated.
[0006] In order to solve the above problems, we propose a multifunctional ruler for detecting screw pitch. Utility Model Content

[0018] The utility model is further configured as follows: a second scale line is sprayed on the top of the second ruler plate.
[0019] The above technical solution is adopted to facilitate observation of the pitch of the screw rod by setting the second scale line.
[0020] In summary, the utility model has the following beneficial effects:
[0021] 1. The utility model drives the second ruler plate to move up and down by setting an adjusting screw. When detecting the screw rod, the second ruler plate and the ruler plate pair can be used to clamp the screw rod, thereby ensuring the stability of the screw rod and avoiding the screw rod movement caused by holding the screw rod, thereby affecting the detection accuracy;
[0022] 2.
