[0021] In this embodiment, if Figure 2 and Figure 3As shown, the positioning assembly 3 includes a positioning pointer 31 arranged on the top of the first scale body 1 and the second scale body 2, a through hole 311 is opened at the center of the positioning pointer 31, a threaded column 33 is inserted in the through hole 311, the bottom end of the threaded column 33 passes through the long through groove 11 and is fixedly connected with a stopper 32, and the top end of the threaded column 33 is threadedly connected with a locking knob 34, and the end of the locking knob 34 can be tightly pressed against the surface of the positioning pointer 31, and the bottom of the first scale body 1 and the second scale body 2 are both located at the long through groove 11. The width of the limiting groove 12 is greater than the long through groove 11, and the stopper 32 is a square structure and is placed in the limiting groove 12. The stopper 32 and the limiting groove 12 are clearance-matched, and the positioning pointer 31 is used to To indicate the position of the embedded bolt, the positioning pointer 31 needs to be moved to the position corresponding to the embedded bolt. When adjusting the position of the positioning pointer 31, the locking knob 34 can be loosened to separate it from the positioning pointer 31, so as to move the positioning pointer 31 within the range of the long through slot 11. When the positioning pointer 31 moves to the embedded bolt, the locking knob 34 is tightened so that the locking knob 34 is pressed against the surface of the positioning pointer 31. At the same time, the stopper 32 is pressed against the limiting groove 12 to lock the position of the positioning pointer 31, which is convenient for adjusting the position of the positioning pointer 31, and convenient for assembling the positioning assembly 3 with the first scale body 1 and the second scale body 2, and convenient for increasing or decreasing the number of positioning assemblies 3 on the first scale body 1 and the second scale body 2.

[0022] In this embodiment, the stopper 32 is a square structure. The structural design of the stopper 32 can prevent it from rotating in the limiting groove 12. The depth of the limiting groove 12 is greater than the thickness of the stopper 32, which can prevent the stopper 32 from protruding from the surfaces of the first scale body 1 and the second scale body 2.

[0023] In this embodiment, if Figure 2 and Figure 3 As shown, the positioning pointer 31 is a diamond structure, and its two ends extend to the outside of the first scale body 1 and the second scale body 2. The two ends of the positioning pointer 31 are convenient for aligning with the embedded bolts. Positioning grooves 13 are symmetrically provided on the top of the first scale body 1 and the second scale body 2 and on both sides of the long through groove 11. The bottom of the positioning pointer 31 is fixedly connected to a positioning column 312 placed in the positioning groove 13. When the positioning pointer 31 adjusts its position, the positioning pointer 31 moves in the positioning groove 13 through the positioning column 312, which limits the positioning pointer 31 and prevents the positioning pointer 31 from deflecting.

[0024] In this embodiment, if Figure 4As shown, the fixing assembly 4 includes a threaded rod 41, a locking sleeve 42, an adjusting knob 43, a connecting plate 44 and a clamping block 45.

The second ruler body 2 is provided with a clamping slot 21 for the clamping block 45 to be clamped into. When the first ruler body 1 and the second ruler body 2 are unfolded in place, the first ruler body 1 is parallel to the second ruler body 2. At this time, by tightening the adjusting knob 43 toward the first ruler body 1, the adjusting knob 43 pushes the positioning sleeve 42 to move into the accommodating groove 15, which can drive the connecting plate 44 and the clamping block 45 to move, and clamp the clamping block 45 into the clamping slot 21, so that the first ruler body 1 and the second ruler body 2 are fixed in the unfolded position, which is convenient for verification.

[0025] Working principle: When in use, the first ruler body 1 and the second ruler body 2 are unfolded to the position, and the adjusting knob 43 is tightened in the direction of the first ruler body 1. The adjusting knob 43 pushes the locking sleeve 42 to move into the receiving groove 15, and the locking sleeve 42 drives the connecting plate 44 and the clamping block 45 to move, and the clamping block 45 is clamped into the clamping groove 21, and the first ruler body 1 and the second ruler body 2 are fixed in the unfolded position, and then the unfolded first ruler body 1 and the second ruler body 2 are placed at the embedded bolt, and the locking knob 34 is loosened to separate them from the positioning pointer 31, so as to move the positioning pointer 31 within the range of the long through groove 11, and the positioning pointer 31 is moved The locking knob 34 is then tightened to make the locking knob 34 press against the surface of the positioning pointer 31. At the same time, the stopper 32 presses against the limiting groove 12 to lock the position of the positioning pointer 31. The positioning pointers 31 of the plurality of positioning components 3 are moved to the corresponding positions of the embedded bolts in the above manner. Then, the distances between the adjacent positioning components 3 are checked and compared with the theoretical values ​​to know whether the embedded bolts are offset. The embedded size of the bolts can be detected quickly and accurately. The operation is simple and the use is convenient. The first ruler body 1 and the second ruler body 2 can be folded and stored to reduce the volume and improve the convenience of carrying.
