[0030] The specific usage and function of this embodiment are as follows:

[0031] In the present utility model, Figure 1 As shown, the folding ruler body 1 is in the straightened locked state. At this time, the lower end of the straightening locking button 4 is inside the insertion hole of the rotating ruler plate 7, and the angle fixing button 3 does not tighten the rotating ruler plate 7. Figure 3 As shown; Figure 1 As shown, when the bearing scale plate 6 and the rotating scale plate 7 need to form an angle, the straightening locking button 4 is rotated to engage with the thread of the superior arc angle measuring plate 2, so that the straightening locking button 4 rises and disengages from the insertion hole of the rotating scale plate 7 through the thread engagement, and the rotating scale plate 7 is rotated forward. The angle is determined by aligning the indicator line of the rotating scale plate 7 with the angle measurement line of the superior arc angle measuring plate 2, and the angle fixing button 3 is rotated to engage with the thread of the superior arc angle measuring plate 2, so that the angle fixing button 3 descends and presses against the top of the rotating scale plate 7 through the thread engagement. The state is as shown in FIG. Figure 5 As shown, the angle between the bearing scale plate 6 and the rotating scale plate 7 is fixed; when Figure 1As shown, when the folding ruler body 1 is folded and stowed, the straightening locking button 4 is rotated to engage with the superior arc angle plate 2, so that the straightening locking button 4 is raised and disengaged from the insertion hole of the rotating ruler plate 7 through the threaded engagement, and the rotating ruler plate 7 is rotated forward to be combined with the supporting ruler plate 6, and the angle fixing button 3 is rotated to engage with the superior arc angle plate 2, so that the angle fixing button 3 is lowered and pressed against the top of the rotating ruler plate 7 through the threaded engagement. Figure 6 As shown, the folding, stowing and fixing of the folding ruler body 1 is achieved thereby.

[0032] Example 2:

[0033] The difference from the first embodiment is that the bottom end surface of the threaded column of the angle fixing button 3 can also be set to a frosted surface, thereby increasing the friction between the bottom end surface of the threaded column of the angle fixing button 3 and the rotating scale plate 7, preventing the angle fixing button 3 from rotating loose.

[0034] Example 3:

[0035] The difference from Example 1 is that the regular hexagonal groove of the assembly limit column 5 can also be set as a regular heptagonal groove, so that the assembly limit column 5 can only be rotated by a special tool that cooperates with the regular heptagonal groove, preventing non-staff from rotating and disassembling the assembly limit column 5.
