After the reverse threaded cylinder 1034 is fixed inside the through hole 1031, the threaded knob 103 can be rotated and fixedly installed by the internal thread structure 1035 inside the reverse threaded cylinder 1034.

[0028] In order to facilitate the reverse threaded cylinder 1034 to be inserted through the through hole 1031 and then fixed in the reverse direction by means of the locking and reinforcing assembly, in this embodiment, preferably, the locking and reinforcing assembly includes an inner reverse threaded ring 1036 that is rotated in the opposite direction and installed on the outer surface of the reverse threaded cylinder 1034. Both sides of the inner reverse threaded ring 1036 are integrally formed with engagement grooves 1037. After the reverse threaded cylinder 1034 is inserted through the through hole 1031 and limited, the wrench is engaged in the engagement groove 1037 to drive the inner reverse threaded ring 1036 to rotate in the opposite direction on the outer surface of the reverse threaded cylinder 1034 for reinforcement installation.

[0029] The surface of the slide body 106 is provided with a scratch-resistant protection mechanism, which includes a scratch-resistant protection component disposed on the surface of the slide body 106. A locking and mounting component is disposed between the inner side of the scratch-resistant protection component and the slide body 106. The scratch-resistant protection mechanism can protect the surface of the slide body 106 during length adjustment, and the surface of the short ruler 105 and the inside of the support groove 107 are not easily scratched or damaged during sliding adjustment.

[0030] To facilitate the protection of the outer surface of the slider 106 by means of an anti-scratch protection component, and to prevent scratch damage to the surface of the short ruler 105 and the interior of the support groove 107 during sliding, in this embodiment, preferably, the anti-scratch protection component includes a rubber sleeve 1061 disposed on the surface of the slider 106, and the inner surface of the rubber sleeve 1061 contacts the outer surface of the slider 106. The rubber sleeve 1061 can be installed on the surface of the slider 106, and when the surface of the slider 106 contacts the surface of the short ruler 105 and the interior of the support groove 107 during sliding adjustment, friction scratches are less likely to occur, effectively protecting the use.

[0031] In order to facilitate the snap-fit ​​installation of the rubber sleeve 1061 by means of the snap-fit ​​installation component, in this embodiment, preferably, the snap-fit ​​installation component includes rubber clips 1062 integrally formed on both sides inside the rubber sleeve 1061, and slots 1063 are provided on both sides of the slide body 106 to engage with the rubber clips 1062. The rubber sleeve 1061 can be installed on the surface of the slide body 106 for protection by snapping the rubber clips 1062 into the slots 1063.

[0032] The working principle and usage process of this utility model are as follows: Before using this multi-functional ruler, installation is performed by inserting the reverse threaded cylinder 1034 through the through hole 1031. The hexagonal limiting block 1033 is engaged with the inner hexagonal limiting groove 1032. Then, the wrench is engaged on the surface of the engagement groove 1037, causing the inner reverse threaded ring 1036 to rotate in the opposite direction. The outer surface of the reverse threaded cylinder 1034 is fixedly installed inside the through hole 1031, thus allowing adjustment between the long ruler 101 and the short ruler 105. After reaching the desired length and vertical angle, the threaded knob 103 is inserted through the slide body 102 and the internal thread structure 1035 inside the reverse threaded cylinder 1034 for reinforcement and installation. If the internal thread structure 1035 is damaged due to long-term adjustment, the reverse threaded cylinder 1034 can be disassembled and replaced by reversing the operation. The disassembly and replacement cost is small, which improves the convenience of disassembly and replacement when the internal thread structure 1035 is damaged during the use of the multi-functional ruler. When it is necessary to directly measure the length, the long ruler 101 and the short ruler 105 can be closed in a straight line and fixed before use.

[0033] Before use, the rubber sleeve 1061 is closed on the outer surface of the slide body 106 by the rubber clip 1062 engaging inside the slot 1063. This facilitates the protection of the slide body 106. When adjusting between the long ruler 101 and the short ruler 105 by sliding the slide body 106 and the support groove 107, if the rotation is large during adjustment, the lower surface of the rubber sleeve 1061 will contact the surface of the short ruler 105. This prevents the slide body 106 from contacting the surface of the short ruler 105 and the inside of the support groove 107, thus effectively protecting it during adjustment and improving the convenience of scratch protection for the slide body 106 during use of the multi-functional ruler.
