[0026] See also Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The utility model provides a portable measuring tool, the folding structure 4 includes a threaded column 41, the threaded column 41 is fixed to the middle of the ruler plate 1, a first connecting plate 42 connected to the threaded column 41, the first folding plate 11 is fixed to the first connecting plate 42 by bolts, a second connecting plate 43 connected to the threaded column 41, the second connecting plate 43 is located at the upper end of the first connecting plate 42, the second folding plate 12 is fixed to the second connecting plate 43 by bolts, a fixing nut 44 threadedly connected to the threaded column 41, a folding frame 45 is provided on the ruler plate 1, and a limited baffle 46 is integrally formed on the outer edge of the toothed plate 1. After the second folding plate 12 is unfolded, it is attached to the surface of the limited baffle 46. The second folding plate 12 can be limited after being unfolded. A positioning rod 421 is provided on the surface of the first connecting plate 42, and a positioning groove 431 is provided on the second connecting plate 43. When the second connecting plate 43 is overlapped with the first connecting plate 42, the positioning rod 421 is stuck in the positioning groove 431, and the second connecting plate 43 can be lifted and overlapped on the first connecting plate 42 to be locked, thereby improving the stability after overlapping. A stopper 432 is integrally formed on the edge of the second connecting plate 43. After the first folding plate 11 and the second folding plate 12 are unfolded, the stopper 432 will abut against the edge of the first connecting plate 42, and the second connecting plate 42 can be abutted, thereby improving the stability of the first folding plate 11 after being unfolded.

[0027] The threaded column 41 is equipped with a positioning structure 47, which includes a positioning port 471, which is arranged on the first connecting plate 42 and the second connecting plate 43. The first connecting plate 42 is also provided with a second positioning port 474, a positioning block 472 plugged with the positioning port 471, and the positioning block 472 is arranged on the surface of the pressing plate 473 and is pressed and fixed by a fixing nut 44 fixed on the threaded column 41;
