Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-6 As shown, a portable measuring tool for construction includes a measuring tape box 1. A fixed ruler plate 2 is fixedly connected to the outer surface of the measuring tape box 1. A bubble level 3 is fixedly connected to the front surface of the fixed ruler plate 2. A fixing block 4 is located on the side of the measuring tape box 1 away from the fixed ruler plate 2. A pull-out opening 16 is provided through the surface of the fixing block 4 away from the measuring tape box 1. A measuring tape body 17 is slidably connected to the inner surface of the pull-out opening 16. A pull buckle is fixedly connected to the outer surface of the guide roller 9 and the opposite surfaces of the two brush layers 10. The measuring tape body 17 is pulled out by means of a pull buckle. An upper cleaning box 5 is provided on the surface of the fixing block 4 away from the measuring tape box 1. An insert 6 is fixedly connected to the bottom surface of the upper cleaning box 5. Below the cleaning box 5 is a lower cleaning box 7. The upper cleaning box 5 and the lower cleaning box 7 are both fixedly connected to the surface near the fixing block 4. The surface of the fixing block 4 away from the measuring tape box 1 has a connecting groove that matches the structural size of the connecting block 18. The connecting block 18 is inserted into the connecting groove to connect the upper cleaning box 5, the lower cleaning box 7 and the fixing block 4. The front and rear surfaces of the lower cleaning box 7 are provided with snap-fit ​​mechanisms 8. The inner surface of the lower cleaning box 7 and the inner surface of the upper cleaning box 5 are both movably connected to the guide rollers 9 through bearings. The inner cavity of the lower cleaning box 7 and the inner cavity of the upper cleaning box 5 are both provided with brush layers 10. The two brush layers 10 are fixedly connected to the lower cleaning box 7 and the upper cleaning box 5 respectively with their backs to each other. The brush layers 10 are nylon brushes.

[0028] like Figure 3As shown, the top surface of the lower cleaning box 7 has an insertion slot 19, which matches the structural dimensions of the insert body 6. The top surface of the lower cleaning box 7 is slidably connected to the bottom surface of the upper cleaning box 5. The locking mechanism 8 includes four sleeve boxes 81 located on the front and rear surfaces of the lower cleaning box 7. The open ends of the four sleeve boxes 81 are all fixedly connected to the lower cleaning box 7. The inner cavity of the sleeve box 81 is provided with a locking spring 82. The end of the locking spring 82 away from the locking post 83 is fixedly connected to the sleeve box 81, and the other end of the locking spring 82 is fixedly connected to the locking post 83. The outer surface of the locking post 83 is slidably connected to the inner side of the sleeve box 81. On the surface, the end of the locking post 83 away from the locking spring 82 is arc-shaped. The two inserts 6 have grooves on their opposite sides that match the structural dimensions of the locking post 83. When the insert 6 is inserted into the insertion groove 19, the insert 6 rests against the arc-shaped position of the locking post 83. As the insert 6 enters the insertion groove 19, the locking post 83 retracts into the sleeve box 81, and the locking spring 82 is compressed and deformed. When the insert 6 is fully inserted into the insertion groove 19, the locking post 83 is aligned with the groove on the surface of the insert 6, the locking spring 82 returns to its original shape, and drives the movement of the locking post 83 to insert the locking post 83 into the groove.

[0029] like Figure 4 , Figure 5 and Figure 6As shown, a motion frame 11 is installed inside the cavity of the fixed ruler plate 2. A sliding block is fixedly connected to the bottom surface of the motion frame 11. The sliding block has a T-shaped vertical cross-section. An open slot matching the structural dimensions of the motion ruler plate is opened on the rear surface of the fixed ruler plate 2. An iron layer is fixedly connected to the end of the open slot away from the limiting mechanism 13. The iron layer is magnetically movably connected to the magnetic block 12. A sliding groove matching the structural dimensions of the sliding block is opened on the bottom surface of the open slot, ensuring that the motion frame 11 assembly can reciprocate in the direction of the fixed ruler plate 2 without interfering with the fixed ruler plate. 2. Separation: A magnetic block 12 is fixedly connected to one side surface of the motion frame 11. A limiting mechanism 13 is provided on the side surface of the motion frame 11 away from the magnetic block 12. The limiting mechanism 13 includes a limiting box 131 fixedly connected to one end of the motion frame 11. A movable plate 132 is slidably connected to the inner cavity of the limiting box 131. A limiting spring 133 is fixedly connected to one side surface of the movable plate 132. The end of the limiting spring 133 away from the movable plate 132 is fixedly connected to the limiting box 131. A limiting post 134 is fixedly connected through one side surface of the movable plate 132. A pull rod 20 is fixedly connected to the end of the frame 11. One side of the pull rod 20 is slidably connected to the limiting box 131. The end of the limiting post 134 away from the pull rod 20 is movably connected to the limiting box 131. Pulling up the pull rod 20 can drive the movement of the combination of the limiting post 134 and the moving plate 132. The inner cavity of the motion frame 11 is provided with a movable ruler plate 14. The rear surface of the motion frame 11, the rear surface of the fixed ruler plate 2, and the rear surface of the movable ruler plate 14 are all on the same plane. The front surface of the fixed ruler plate 2 and the front surface of the movable ruler plate 14 are all coated with a scale layer. The movable ruler plate 14... Both sides of the surface are fixedly connected with a snap-fit ​​block 15. The snap-fit ​​block 15 has a T-shaped horizontal cross section. The inner surfaces of the motion frame 11 are provided with snap-fit ​​grooves that match the structural dimensions of the snap-fit ​​block 15. The end of the limiting post 134 away from the pull rod 20 is located in the inner cavity of the snap-fit ​​groove. When the bottom surface of the movable ruler plate 14 is attached to the motion frame 11, the bottom surface of the limiting post 134 is just located at the top surface of the snap-fit ​​block 15 in the snap-fit ​​groove. The side surface of the snap-fit ​​block 15 near the limiting box 131 is provided with a limiting hole that matches the structural dimensions of the limiting post 134.

[0030] It should be noted that the measuring tape body 17 can be pulled out or retracted from the measuring tape box 1. The measuring tape box 1 has a rotating handle on the front side. Rotating the rotating handle can retract the measuring tape body 17 into the measuring tape box 1. This is a well-known and common technical method, and will not be described in detail here.

[0031] It should be noted that when the motion frame 11 and the movable ruler plate 14 are pulled out to their limit positions, one end of the movable ruler plate 14 is just flush with one end of the fixed ruler plate 2. At this time, moving the movable ruler plate 14 upwards can combine the movable ruler plate 14 and the fixed ruler plate 2 to form a ruler plate body with a flush top surface.

[0032] It should be noted that the measuring tape box 1, the fixed ruler plate 2, and the bubble level 3 are combined to form a measuring tool, and the fixed ruler plate 2 and the movable ruler plate 14 can be extended and retracted, making the measuring tool more portable.

[0033] Working principle: In use, the fixed ruler plate 2 can be placed close to the wall. The wall's flatness can be observed using the bubble level 3. The measuring tape 17 is then pulled out of the measuring tape box 1 using the pull tab. Measurements are taken at the construction site. After measurement, the measuring tape 17 is returned to the measuring tape box 1. At this time, the measuring tape 17 has been cleaned by the brush layer 10 in the upper cleaning box 5 and lower cleaning box 7, passes through the gap between the two guide rollers 9, and enters the measuring tape box 1. Further, if the upper cleaning box 5 and lower cleaning box 7 need to be disassembled and cleaned, they are moved in opposite directions. At this time, the groove on the surface of the insert 6 will abut against the arc-shaped surface of the locking post 83. When the locking post 83 completely disengages from the groove on the surface of the insert 6, the upper cleaning box 5 and lower cleaning box 7 can be separated. When performing straight line measurements or drawing straight lines, the motion frame 11 assembly is pulled out from the fixed ruler plate 2 until it reaches its limit position. At this point, the movable ruler plate 14 and the fixed ruler plate 2 are on the same vertical plane. Further, the limit post 134 is pulled by the pull rod 20, which drives the movement of the movable plate 132 and the limit post 134 assembly. The limit spring 133 is compressed, and the movable ruler plate 14 moves upward until it is flush with the fixed ruler plate 2. At this point, the pull rod 20 is released, the limit spring 133 returns to its original state, and the movement of the movable plate 132 and the limit post 134 is driven. The limit post 134 is inserted into the limit hole on the locking block 15, which limits the position of the locking block 15 and the movable ruler plate 14. At this point, the top surfaces of the fixed ruler plate 2 and the movable ruler plate 14 are on the same horizontal plane.
