Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] See also Figure 1-9 In an embodiment of the utility model, a fine-tuning digital level fixed base includes a fixed plate 1, an adjustment component 5 is provided above the fixed plate 1; the adjustment component 5 has a first rotating shaft 51, a movable frame 52, a second rotating shaft 53 and a mounting plate 54, and the first rotating shaft 51, the movable frame 52 and the second rotating shaft 53 constitute a fine-tuning mechanism that allows the mounting plate 54 to swing forward, backward, left and right; the two sides of the mounting plate 54 axially arranged along the first rotating shaft 51 are respectively provided with a first fine-tuning component 55 and a first traction spring 56; the two sides of the mounting plate 54 axially arranged along the second rotating shaft 53 are respectively provided with a second fine-tuning component 57 and a second traction spring 58; the two ends of the second rotating shaft 53 are fixed with the mounting plate 54 through end plates.

[0036] Specifically, the movable frame 52 is arranged in a "mountain" shape and is rotatably connected to the first rotating shaft 51; a second rotating shaft 53 is provided at the upper end of the movable frame 52 along the radial direction of the first rotating shaft 51; and the second rotating shaft 53 is rotatably connected to the movable frame 52.

[0037] The upper end of the first fine-tuning component 55 is movably connected to the U-shaped groove opened in the mounting plate 54 through a rotating shaft, and the lower end is movably connected to the movable sleeve 59; the upper end of the first traction spring 56 is fixed to the mounting plate 54, and the lower end is fixed to another movable sleeve 59; the two movable sleeves 59 are sleeved on both ends of the first rotating shaft 51 and are rotatably connected.

[0038] By adopting the above technical solution, when the first fine-tuning component 55 is actuated, the mounting plate 54 flips around the center of the second rotating shaft 53, thereby achieving left-right adjustment of the mounting plate 54; the first traction spring 56 is provided to assist in balancing the mounting plate 54 when adjusting left-right.

[0039] When the second fine-tuning component 57 is in operation, the movable frame 52, the second rotating shaft 53 and the mounting plate 54 are deflected around the first rotating shaft 51, thereby achieving the front and rear adjustment of the mounting plate 54. The two second traction springs 58 are provided to ensure the balance of the front and rear adjustment of the mounting plate 54.

[0040] Through the arrangement of the above structure, the mounting plate 54 can be finely adjusted in the front, back, left and right directions, ensuring that the laser inside the level is in a relatively stable position for outputting laser light.

[0041] In this embodiment, the upper end of the second fine-tuning component 57 is movably connected to the U-shaped frame 510 via a rotating shaft; a convex shaft is provided on the inner side of the U-shaped frame 510, and is installed at the bottom of one side of the mounting plate 54 through a seat bearing; and the lower end of the second fine-tuning component 57 is movably connected to the fixed disk 1; and both ends of the second traction spring 58 are fixedly connected to the fixed disk 1 and the mounting plate 54.

[0042] As a further explanation, when the mounting plate 54 is fine-tuned left and right, the second fine-tuning component 57 will interfere with the rotation of the mounting plate 54. For this reason, a convex shaft is provided on the inner side of the U-shaped frame 510, and is installed at the bottom of one side of the mounting plate 54 through a seat bearing. This can prevent the second fine-tuning component 57 from interfering with the rotation of the mounting plate 54; and when the second fine-tuning component 57 is in motion, the movable sleeve 59 will cooperate with the mounting plate 54 to deflect, ensuring that the second fine-tuning component 57 and the first fine-tuning component 55 do not interfere with each other when they are in motion.

[0043] In this embodiment, a bracket 6 is fixed above the mounting plate 54 , a support member 7 is fixed inside the bracket 6 , a trapezoidal body 8 is provided on the top of the support member 7 , and lasers 13 are fixed on the four inclined surfaces outside the trapezoidal body 8 .

[0046] Specifically, the projection window 9 adopts an angled glass window, which can transform the line laser into a rectangular wireframe laser line, thereby increasing the laser projection range.

[0047] In this embodiment, a function key 10 is embedded in the middle position of the top of the shell 3, and the function key 10 is electrically connected to the control board 11; the control board 11 is electrically connected to the laser 13 and the rotary switch 12; the laser 13 and the rotary switch 12 are electrically connected to the battery 4.

[0048] In this embodiment, the bottom of the fixed plate 1 is threadedly connected with a support leg 2, and there are three support legs 2, which are arranged in a circular array at the bottom of the fixed plate 1, and an angle sensor 14 is embedded in the middle position of the bottom of the fixed plate 1; the angle sensor 14 is electrically connected to the control board 11.

[0049] In this embodiment, the first fine-tuning component 55 and the second fine-tuning component 57 are composed of the same structure, both include a stepper motor 511, and a screw rod 512 is installed on the output shaft of the stepper motor 511; the lower end of the screw rod 512 is connected to the wire reel 513; the bottom of the wire reel 513 is provided with a movable ear; the stepper motor 511 is electrically connected to the control board 11 and the rotary switch 12.

[0050] Furthermore, protruding columns are welded at both ends of the stepper motor 511 , and the protruding columns are rotatably connected to the U-shaped groove or U-shaped frame on the mounting plate 54 , so as to generate an angular displacement compensation when the mounting plate 54 is deflected.
