[0032] By adopting the above technical solution, when the device needs to be placed on a cement floor for use, the threaded rod 3 is rotated by turning the handle 11, and the rotation of the threaded rod 3 drives the annular plate 9 to move downward, and at the same time the limiting rod 12 slides in the bottom plate 1, and the threaded rod 3 is stopped when the lower end of the annular plate 9 is lower than the lower end of the lower cone 10. The device can be placed on a cement floor for use through the annular plate 9. The setting of the annular plate 9 allows the device to be placed on a cement floor for use, and avoids the situation where the setting of the lower cone 10 makes it impossible for the device to be placed on a cement floor for use.
[0033] Specifically, the inner wall of the annular plate 9 is tangent to the side of the lower cone 10 , threaded holes and sliding holes corresponding to the threaded rod 3 and the limiting rod 12 are respectively provided in the bottom plate 1 , and a bearing rotating seat is provided between the threaded rod 3 and the annular plate 9 .
[0034] By adopting the above technical solution, the rotation of the threaded rod 3 can drive the annular plate 9 to move, and the movement of the annular plate 9 can avoid scratching the side of the lower cone 10.
[0035] When this embodiment is used, by setting the annular plate 9, when the device needs to be placed on a cement floor for use, the threaded rod 3 is rotated by the turning handle 11, and the rotation of the threaded rod 3 drives the annular plate 9 to move downward, and at the same time the limiting rod 12 slides in the bottom plate 1, and the threaded rod 3 stops rotating when the lower end of the annular plate 9 is lower than the lower end of the lower cone 10, and the device can be placed on a cement floor for use through the annular plate 9. By setting the annular plate 9, the device can be placed on a cement floor for use, and the setting of the lower cone 10 avoids the situation where the device cannot be placed on a cement floor for use.
[0036] The structure and working principle of the bottom plate 1, connecting sleeve 4, support platform 5, connecting head 6, support rod 7, connecting tube 8 and lower cone 10 in the utility model have been disclosed in the electronic level bracket disclosed in Chinese patent application No. 2023201889898, and its working principle is that the lower end of the level is connected to the connecting head 6 on the support platform 5, and then the lower cone 10 at the lower end of the bottom plate 1 can be inserted into the ground, and then the level can be leveled and used through the leveling mechanism on the level.
[0037] The working principle and use process of the utility model are as follows: when the adjustable bracket of the level is used in construction projects, the device is installed in a suitable position, and the lower end of the level is connected to the connecting head 6 on the support platform 5. Then the lower cone 10 at the lower end of the base plate 1 can be inserted into the ground, and then the leveling mechanism on the level can be used to level the level. By setting the adjusting component 2, when it is necessary to adjust the height of the support platform 5, the folding rod 25 is pulled to drive the limit plate 26 to slide in the fixed cylinder 21, and the spring 27 is compressed. Then, the support rod 7 is pulled to slide in the connecting sleeve 4. At the same time, the slider 22 at one end of the support rod 7 slides in the slide groove 23 of the connecting sleeve 4. After the support platform 5 reaches a suitable height, the folding rod 25 is released, and the spring 27 is stretched to push one end of the folding rod 25 into the corresponding card hole 24 on the side of the support rod 7, so as to achieve the effect of limiting and fixing the support rod 7. The height of the support platform 5 can be adjusted by setting the adjusting component 2. The adjustment speed is faster. By setting the fine-adjustment component 28, after the height of the support platform 5 is adjusted to the approximate range, the screw rod 283 is rotated by the knob 284. The rotation of the screw rod 283 drives the slide plate 285 to slide in the fixed box 281. The slide plate 285 moves and pushes the support platform 5 through the push column 282 to fine-tune the height. By setting the fine-adjustment component 28, the height adjustment of the support platform 5 is more precise. By setting the annular plate 9, when the device needs to be placed on the cement floor for use, the threaded rod 3 is rotated by the turning handle 11. The rotation of the threaded rod 3 drives the annular plate 9 to move downward. At the same time, the limit rod 12 slides in the bottom plate 1. When the lower end of the annular plate 9 is lower than the lower end of the lower cone 10, the threaded rod 3 is stopped. The device can be placed on the cement floor for use through the annular plate 9. By setting the annular plate 9, the device can be placed on the cement floor for use, which avoids the situation where the device cannot be placed on the cement floor for use due to the setting of the lower cone 10.
