[0037] See also Figure 5 , Figure 6 and Figure 7 The connecting assembly 7 includes a rotating shaft 71 rotatably connected to the outside of the level device 8, a movable plate 72 is installed at one end of the rotating shaft 71, a fixing hole 73 is provided at the bottom of the movable plate 72, a rotating plate 74 is installed on the outer side of the rotating shaft 71, a mounting seat 75 is installed on the top of the mounting frame 6, a notch 76 and a through slot 77 are respectively provided inside the mounting seat 75, a sliding rod 78 is connected inside the mounting seat 75 and located at the position of the notch 76, a fixing plate 79 is installed at one end of the sliding rod 78, a pulling plate 710 is installed at the other end of the sliding rod 78, a second spring 711 is installed on the outer side of the mounting seat 75 and located outside the sliding rod 78, and one end of the second spring 711 is connected to the pulling plate 710;

[0038] The level device 8 is connected to the top of the mounting frame 6 by the connection assembly 7, so that the level device 8 can be quickly installed or disassembled. The staff does not need to hold the level device 8 for verticality detection, thereby improving the accuracy of the detection; the movable plate 72 is rotatably connected to the outside of the level device 8 through the rotating shaft 71, and the movable plate 72 can be located at the position of the through groove 77 for movement; the outer wall of the pulling plate 710 is provided with several groups of rubber particles distributed in a circular shape to increase friction and facilitate the user to pull.

[0039] The implementation principle of this embodiment is as follows: the level device 8 and the height adjustment device can be quickly installed or disassembled. The user only needs to disassemble the level device 8 through the connecting assembly 7. The user only needs to hold the pull plate 710 and pull it outward. The pull plate 710 drives the fixed plate 79 to move through the slide bar 78. The second spring 711 is in an elongated state. When the fixed plate 79 is located inside the notch 76, the user holds the rotating plate 74 and rotates the movable plate 72. When the movable plate 72 is separated from the through slot 77, the level device 8 can be disassembled from the top of the mounting frame 6. The two connecting assemblies 7 perform the same operation.

[0040] When it is necessary to connect the level device 8 to the mounting bracket 6, the user pulls the pull plate 710 outward by holding the pull plate 710, and the fixed plate 79 is located inside the notch 76. Then, when the user rotates the movable plate 72 by holding the rotating plate 74 until the movable plate 72 is located inside the through slot 77, the user releases the pull plate 710. At this time, the fixed plate 79 is reset by the second spring 711. When the fixed plate 79 is located inside the fixing hole 73, the movable plate 72 can be fixed inside the through slot 77. At this time, the level device 8 is successfully connected to the top of the mounting bracket 6.

[0041] The user can adjust the mounting frame 6 to different heights, which is convenient for using the level ruler device 8 at different heights. The user only needs to hold the two push plates 59 and move them to both ends at the same time. At this time, the connecting plate 57 drives the positioning plate 58 to move inside the groove 52, and the connecting plate 57 squeezes the telescopic rod 55 and the first spring 56. When the two positioning plates 58 are both out of the two positioning grooves 4, the user flips the connecting seat 51 and finally releases the push plate 59. The user can move the connecting frame 2 up and down inside the support frame 1 until it moves to a suitable height. The user holds the two push plates 59 and moves them to both ends. When the two positioning plates 58 are both located inside the grooves 52, the user flips the connecting seat 51 again, locates the mounting rod 3 at the position of the through hole 54, and then releases the push plate 59. The connecting plate 57 is reset by the setting of the telescopic rod 55 and the first spring 56. At this time, the two positioning plates 58 are located inside the two positioning grooves 4, so that the connecting frame 2 can be fixed inside the support frame 1. At this time, the height adjustment is completed.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
