[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. Example

[0023] like Figure 1-4 As shown, this utility model provides a building construction flatness testing device, including an electronic ruler body 1. Two outer rods 2 are provided at one end of the electronic ruler body 1. A rotating handle 3 is movably installed through the outer surface of the outer rod 2. A gear 4 is fixedly installed through one end of the rotating handle 3. An inner rod 5 is slidably connected to the inner wall of the outer rod 2. A limiting hole 501 is opened through the outer surface of the inner rod 5. A sliding groove 502 is opened through the outer surface of the inner rod 5 away from the limiting hole 501. One end of the rotating handle 3 is slidably connected to the inner wall of the sliding groove 502. A rack 503 is fixedly installed on the inner wall of the inner rod 5. The outer surface of the gear 4 meshes with one end of the rack 503. One end of the rotating handle 3 is slidably connected through one end of the gear 4 to the inner wall of the limiting hole 501. The gear 4 is located inside the inner rod 5.

[0024] The specific settings and functions of this embodiment are described below. When a shorter worker uses the device for measurement, the worker can hold the rotating handle 3 and pull it outward to rotate it. The rotating handle 3 drives the gear 4 to rotate. When the gear 4 rotates, it causes the rack 503 to move. The rack 503 drives the inner rod 5 to extend outward. After extending a certain length, the worker stops rotating the rotating handle 3 and presses it down into the limiting hole 501 to complete the fixation. The height of the gear 4 should be set so that it can mesh with the rack 503 even when one end of the rotating handle 3 is disengaged from the limiting hole 501. Afterward, the worker adjusts the rod on the other side. When the rods on both sides are at different lengths, the electronic ruler body 1 can be tilted at different angles, which is convenient for shorter workers to check the levelness of the wall. Example

[0025] like Figure 2 and Figure 4 As shown, a mounting post 6 is fixedly sleeved on the inner wall of one of the limiting holes 501. A sliding piece 7 is fixedly installed on one end of the mounting post 6. Two fixed cylinders 8 are fixedly installed on one end of the electronic ruler body 1. One end of the sliding piece 7 is slidably connected to the inner wall of the fixed cylinder 8. A telescopic post 9 is fixedly installed on one end of the inner wall of the fixed cylinder 8. A spring 10 is provided on one end of the inner wall of the fixed cylinder 8. A fixed rod 701 is fixedly connected to the outer surface of the sliding piece 7. A limiting block 702 is fixedly connected to one end of the fixed rod 701. A through groove 801 is opened through the outer surface of the fixed cylinder 8. A limiting groove 802 is opened on one end of the inner wall of the through groove 801. One end of the fixed rod 701 is slidably connected to the inner wall of the through groove 801. The length of the limiting block 702 is greater than the length of the limiting groove 802. One end of the spring 10 is fixedly connected to the bottom end of the inner wall of the fixed cylinder 8. The other end of the spring 10 is fixedly connected to one end of the sliding piece 7.

[0026] The overall effect of this embodiment is that, during measurement, the worker can hold the outer rod 2 and press down the outer rod 2 and inner rod 5 together before rotating them. At this time, the sliding piece 7 rotates inside the fixed cylinder 8, and the fixed rod 701 slides in the through groove 801. After rotating to a suitable angle, the worker stops rotating the rod. At this time, the fixed rod 701 is locked in the limiting groove 802. The limiting block 702 can prevent the fixed rod 701 from sliding out of the through groove 801. When the sliding piece 7 rotates, the spring 10 will twist and the spring 10 will produce elastic deformation. After the worker stops rotating the rod, the spring 10 will release its elastic force, causing the fixed rod 701 to be locked in the limiting groove 802 and fixed. This makes it possible to form a larger angle between the rod and the electronic ruler body 1, which is convenient for the worker to perform multi-angle measurements.

[0027] The usage and working principle of this device are as follows: When a shorter worker uses the device for measurement, the worker can hold the rotating handle 3 and pull it outward to rotate it. The rotating handle 3 drives the gear 4 to rotate. When the gear 4 rotates, it causes the rack 503 to move. The rack 503 drives the inner rod 5 to extend outward. After it extends to a certain length, the worker stops rotating the rotating handle 3 and presses it down into the limiting hole 501 to complete the fixation. The height of the gear 4 should be set so that it can mesh with the rack 503 even when one end of the rotating handle 3 is disengaged from the limiting hole 501. Then the worker adjusts the rod on the other side. When the rods on both sides are at different lengths, the electronic ruler body 1 can be tilted at different angles, which is convenient for shorter workers to check the levelness of the wall. During measurement, the worker can hold the outer rod 2 and press down the outer rod 2 and inner rod 5 together before rotating them. At this time, the sliding piece 7 rotates inside the fixed cylinder 8, and the fixed rod 701 slides in the through groove 801. After rotating to a suitable angle, the worker stops rotating the rod. At this time, the fixed rod 701 is locked in the limiting groove 802. The limiting block 702 can prevent the fixed rod 701 from sliding out of the through groove 801. When the sliding piece 7 rotates, the spring 10 will twist and the spring 10 will produce elastic deformation. After the worker stops rotating the rod, the spring 10 will release its elastic force, so that the fixed rod 701 is locked in the limiting groove 802 and fixed. This makes the rod and the electronic ruler body 1 form a larger angle, which is convenient for the worker to perform multi-angle measurements.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
