The fixing component 2 includes a fixing column 21 fixedly connected to the base 1, and a vertical rectangular groove 22 is opened on the arc surface of the fixing column 21. A trapezoidal block 23 is slidably arranged in the rectangular groove 22. By setting the fixing component 2, when fixing the mounting plate 4 to the base 1, the mounting plate is dragged so that the fixing column 21 is inserted into the mounting plate, and the trapezoidal block 23 in the rectangular groove 22 is reset to limit the mounting plate 4, thereby fixing the mounting plate to the base 1.

[0027] Slide grooves 24 are provided on the inner walls at the upper and lower ends of the rectangular groove 22, and connecting blocks 27 are fixed at the upper and lower ends of the trapezoidal block 23. The connecting block 27 is slidably connected in the slide groove 24. When the fixing column 21 is inserted into the mounting plate 4, the mounting plate 4 contacts the trapezoidal block 23, and the mounting plate 4 is pressed downward, so that the trapezoidal block 23 is retracted into the rectangular groove 22.

[0028] An auxiliary rod 26 is arranged along the length direction in the slide groove 24, and the auxiliary rod 26 passes through the connecting block 27. The connecting block 27 slides on the auxiliary rod 26. A spring 25 is connected to one side of the connecting block 27, and the other end of the spring 25 is connected to the fixing column 21. The trapezoidal block 23 is retracted into the rectangular groove 22, so that the spring 25 is compressed. After the mounting plate 4 moves downward and separates from the trapezoidal block 23, the spring 25 is reset, so that the trapezoidal block 23 is reset.

[0029] A circular groove 28 is provided on the top of the connecting block 27 on the upper part of the trapezoidal block 23, and a circular groove 29 is provided on the top of the inner wall of the rectangular groove 22. A latch 210 is slidably connected in the circular groove 29. A spring 211 and a pull rope 212 are fixedly connected to the upper end of the latch 210. The other end of the spring 211 is connected to the fixed column 21. When it is necessary to limit the trapezoidal block 23, the trapezoidal block 23 is squeezed so that the trapezoidal block 23 moves to the latch 210. The spring 211 and the pull rope 212 are fixedly connected to the upper end of the latch 210. The pull rope 212 is pulled so that the fixed column 21 in the circular groove 29 moves up, the spring 211 is compressed, the latch 210 is adapted to the circular groove 28, the pull rope 212 passes through the fixed column 21, the pull rope 212 is loosened, and the spring 211 drives the latch 210 to reset so that it is inserted into the circular groove 28, thereby limiting the trapezoidal block 23.

The laser lamp 34 emits light horizontally and vertically to the mirror 33. When the base 1 needs to be adjusted horizontally, the laser lamp 34 is started to illuminate the mirror 33, and the scale 36 on the curved plate 35 is illuminated by reflection. According to the illuminated scale 36, the threaded rod 31 is turned to change the distance between the pad 32 and the base 1, and then the base 1 is adjusted to be horizontal.

When the plumb bob 8 reaches the bottom, the screw rod 10 on the limit plate 9 is inserted into the pulley 6, and then the pulley 6 is limited. The depth is measured by reading the measuring rope 7. When the mounting plate 4 is fixed to the base 1, the mounting plate 4 is dragged so that the fixing column 21 is inserted into the mounting plate 4. When the fixing column 21 is inserted into the mounting plate 4, the mounting plate 4 contacts the trapezoidal block 23, and the mounting plate 4 is pressed down so that the trapezoidal block 23 is retracted into the rectangular groove 22. The trapezoidal block 23 is retracted into the rectangular groove 22 so that the connecting block 27 in the slide groove 24 slides on the auxiliary rod 26, so that the spring 25 is compressed. After the mounting plate 4 moves down and separates from the trapezoidal block 23, the spring 25 is reset. The trapezoidal block 23 is reset, and the reset of the trapezoidal block 23 limits the mounting plate 4, and then the mounting plate 4 is fixed to the base 1.

The spring 211 drives the latch 210 to reset and insert it into the circular slot 28, thereby limiting the trapezoidal block 23. When the level of the base 1 needs to be adjusted, the laser light 34 is started to illuminate the mirror 33, and the scale 36 on the arc plate 35 is illuminated by reflection. According to the illuminated scale 36, the threaded rod 31 is turned to change the distance between the cushion block 32 and the base 1, and then the base 1 is adjusted to be level.
