[0030] Refer to Figure 1 and Figure 2, an embodiment provided by the present utility model: a combined measuring tool convenient for storage, including a ruler case 1. A sliding case 3 is arranged on the inner wall of the ruler case 1. A chute 9 is opened in the middle of the top wall of the sliding case 3. A limiting block 8 is fixedly connected to the inner top wall of the ruler case 1. The bottom wall of the limiting block 8 is slidably connected to the chute 9. Threaded columns 4 are rotatably connected to the left and right ends of the front side of the sliding case 3. Knobs 5 are fixedly connected to the front sides of the two threaded columns 4. The rear ends of the threaded columns 4 are threadedly connected to a displacement plate 6. The front side of the displacement plate 6 is slidably connected to the inner wall of the sliding case 3. Ruler plates 7 are fixedly connected to both the displacement plate 6 and the rear side of the ruler case 1. A movable plate 11 is rotatably connected to the right side of the ruler case 1. Locking mechanisms 2 are arranged on the front and rear sides of the top wall of the movable plate 11. The locking mechanisms 2 facilitate locking the movable plate 11, thereby achieving the purpose of protecting the sliding case 3;

[0031] Specifically, by pulling the sliding case 3, the sliding case 3 can be stably pulled under the sliding connection of the chute 9 and the limiting block 8. This design ensures the stability of the measuring tool during use and avoids measurement errors caused by unstable sliding.

[0032] Next, by rotating the two knobs 5, the two threaded columns 4 are rotated. This step is to adjust the position of the displacement plate 6 so that, under the rotational restriction of the inner wall of the sliding case 3, the ruler plate 7 on the right side moves backward. During the backward movement of the ruler plate 7, it gradually becomes flush with the ruler plate 7 on the left side. In this way, the purpose of increasing the use length of the ruler plate 7 is achieved. When measurement is not required, the ruler plate 7 can be returned to its original position through reverse operation to complete storage, meeting the measurement requirements in various scenarios, while also taking into account portability, providing accurate measurement results, and greatly improving the work efficiency of users.

[0033] Refer to Figure 2 , scale marks 10 are fixedly connected to the rear sides of the top walls of both the ruler case 1 and the sliding case 3; A handle 16 is fixedly connected to the right side of the sliding case 3. A rubber sleeve 17 is fixedly connected to the middle of the handle 16; Bevels are arranged on the rear sides of the two ruler plates 7;

[0034] Specifically, the scale marks 10 facilitate observing the accurate length, the handle 16 and the rubber sleeve 17 facilitate pulling the sliding case 3, and the bevels arranged on the rear sides of the two ruler plates 7 facilitate accurately aligning with the object to be measured.

[0035] Refer to Figure 1 and Figure 3, the locking mechanism 2 includes two locking posts 201. The bottom walls of the two locking posts 201 are respectively fixedly connected to the front and rear sides of the top wall of the movable plate 11. Locking grooves 202 are opened inside the two locking posts 201. The front and rear ends of the right side of the top wall of the ruler case 1 are both fixedly connected with fixing plates 203. Rotating columns 204 are rotatably connected inside the two fixing plates 203. Two connecting columns 205 are fixedly connected to the outer walls of the two rotating columns 204. Locking arc plates 206 are fixedly connected to the tops of the multiple connecting columns 205. The bottoms of the two locking arc plates 206 respectively penetrate through the corresponding locking grooves 202. A cleaning brush 207 is fixedly connected between the adjacent two fixing plates 203;

[0036] Specifically, by rotating the movable plate 11, the two locking posts 201 reach the front side of the locking arc plate 206. This step is to ensure the stable position of the measurement object during the measurement process and avoid affecting the measurement result due to position changes. Then, rotate the rotating column 204 to complete the locking of the locking arc plate 206 with the locking groove 202 inside the locking post 201. Furthermore, the connecting column 205 is blocked by the locking post 201, so that the front side of the ruler case 1 is closed by the movable plate 11. This design improves the limiting effect on the sliding case 3 and ensures the accuracy of the measurement result. At the same time, the cleaning brush 207 can clean the top of the sliding case 3 that is displaced, avoiding the situation that dirt adheres and affects the scale mark 10.

[0037] Refer to Figure 1 、 Figure 2 and Figure 3 , a protective cover 14 is arranged on the top of the cleaning brush 207. The bottom of the protective cover 14 is rotatably connected to the right side of the top wall of the ruler case 1 through a hinge; A plurality of rubber strips 15 are fixedly connected to the outer walls of the two knobs 5. The outer shapes of the plurality of rubber strips 15 are designed in a square shape; A magnet block 12 is fixedly connected to the left side of the movable plate 11. A magnet groove 13 is opened on the front side of the ruler case 1. The rear side of the magnet block 12 is engaged with the magnet groove 13;

[0038] Specifically, the protective cover 14 can protect the top of the locking mechanism 2. The rubber strips 15 improve the anti-slip effect of the knobs 5. The engagement of the rear side of the magnet block 12 with the magnet groove 13 facilitates the adsorption and engagement of the movable plate 11.

[0039] Working principle: When starting to use, by pulling the sliding case 3, the sliding case 3 can be stably pulled out under the sliding connection of the sliding groove 9 and the limiting block 8. By rotating the two knobs 5, the two threaded columns 4 are rotated, so that the displacement plate 6 is restricted by the rotation inside the inner wall of the sliding case 3, and the right ruler plate 7 is displaced backward, and then is flush with the left ruler plate 7, achieving the purpose of increasing the use length of the ruler plate 7. On the contrary, the storage is completed, achieving the purpose of facilitating the user to carry and use;

[0040] And by rotating the movable plate 11, the two locking columns 201 reach the front side of the locking arc plate 206. Rotate the rotating column 204 to complete the locking of the locking arc plate 206 with the locking groove 202 inside the locking column 201. Further, the connecting column 205 is blocked by the locking column 201, so that the front side of the ruler case 1 is closed by the movable plate 11, thereby improving the limiting effect on the sliding case 3. At the same time, the cleaning brush 207 can clean the top of the displaced sliding case 3, avoiding the situation that dirt adhesion affects the scale mark 10.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
