[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0018] As Figure 1 , 2 The engineering measuring ruler provided by the present application comprises a first ruler body 1 and a second ruler body 2 in sliding cooperation, a first limiting block 3 for clamping the left end of the second ruler body 2 is arranged on the left end of the first ruler body 1 and extends downward perpendicularly, a second limiting block 4 for clamping the right end of the first ruler body 1 is arranged on the right end of the second ruler body 2 and extends upward perpendicularly, a first scale mark 5 is arranged on the front side of the first ruler body 1, a second scale mark 6 is arranged on the front side of the second ruler body 2, and a third scale mark 7 is further arranged on the front side of the second limiting block 4; the scale value of the first scale mark 5 gradually increases from left to right, the scale value of the second scale mark 6 gradually increases from right to left, and the third scale mark 7 continues the first scale mark 5 and the scale value gradually increases from left to right.

[0019] Specifically, a sliding groove 8 with a T-shaped structure is arranged on the lower edge of the first ruler body 1 in the length direction, and a sliding rod 9 matched with the sliding groove 8 is arranged on the upper edge of the second ruler body 2 in the length direction, so that the sliding cooperation of the first ruler body 1 and the second ruler body 2 is easily realized, and the sliding rod 9 can be effectively prevented from sliding out of the sliding groove 8. At this time, in order to improve the sliding stability of the first ruler body 1 and the second ruler body 2, a limiting block 10 is arranged on the upper edge of the first ruler body 1 in the length direction, and a limiting block 11 matched with the limiting block 10 is arranged on the lower edge of the second ruler body 2 in the length direction. Figure 6As shown, a mounting blind hole 10 can also be formed at the right end of the first ruler body 1, which is downwardly open and vertically communicated with the sliding groove 8. A top pressing spring 12 with a pressing block 11 at the lower end is sleeved in the mounting blind hole 10. A fixing nut 13 is embedded in the first ruler body 1 above the mounting blind hole 10. The fixing nut 13 is screwed with a top pressing screw 14. The lower end of the top pressing screw 14 penetrates into the mounting blind hole 10 and is coaxially fixed with the upper end of the top pressing spring 12. The upper end of the top pressing screw 14 is flush with the upper edge of the first ruler body 1. A cross-shaped clamping groove is formed on the end face of the top pressing screw 14 for facilitating the insertion of a screwdriver. The top pressing spring 12 cooperates with the pressing block 11 to press the sliding rod 9 in the sliding groove 8, thereby increasing the friction of the sliding rod 9 when sliding and enhancing the stability of the sliding cooperation between the first ruler body 1 and the second ruler body 2. Meanwhile, the pressure of the top pressing spring 12 can be changed by adjusting the top pressing screw 14, thereby changing the pressure of the pressing block 11 on the sliding rod 9.

[0020] Further, in order to stably fold the first ruler body 1 and the second ruler body 2, as shown in Figure 3 、 4 a first magnetic block 15 can be embedded on the right end face of the first ruler body 1, and a second magnetic block 16 adapted to be attracted to the first magnetic block 15 is embedded on the left end face of the second limiting block 4. The stability of the first ruler body 1 and the second ruler body 2 when folding can be ensured by the adapted attraction between the first magnetic block 15 and the second magnetic block 16. Further, in order to easily realize horizontal adjustment during measurement, a level 17 can be embedded on the front side face of the first ruler body 1. The level 17 can be a common bubble level on the market, which is low in cost and simple and accurate in leveling measurement. Further, in order to facilitate marking the measurement position during measurement, as shown in Figure 5 a plug-in groove 18 can be horizontally formed on the right end face of the second ruler body 2, and a marker pen 19 is adapted to be plugged in the plug-in groove 18.
