The device is characterized by: a pair of symmetrical support plates on the inner wall of the housing, each support plate having a slide rail; the placement plate being placed on the pair of support plates; a slider protruding from the bottom surface of the placement plate and slidably connected to the slide rail; a vertical shaft rotatably mounted on the top rear end of each support plate; the bottom end of the vertical shaft extending through the placement plate to below it and fixedly fitted with a swing arm; a horizontal groove recessed on the bottom surface of the support plate; a rotating wheel rotatably mounted on the top of the other end of the swing arm, slidably connected to the horizontal groove; a first bevel gear fixedly fitted on the top of the vertical shaft; a horizontal shaft above the placement plate, with both ends rotatably connected to the left and right inner walls of the housing; a second bevel gear fixedly fitted on the horizontal shaft and meshing with the first bevel gear; a first sprocket fixedly fitted on the horizontal shaft; a drive motor fixed on the inner wall of the housing; a second sprocket fixed at the output end of the drive motor; and a chain directly wound around the first and second sprockets.

[0006] As a further improvement of the present invention, the slide rail is arranged perpendicular to the transverse groove.

[0007] As a further improvement of the present invention, the drive motor is a forward and reverse reversible motor.

[0008] As a further improvement of the present invention, the two ends of the horizontal shaft are rotatably connected to the inner wall of the box through bearing seats.

[0009] As a further improvement of the present invention, the slider is slidably connected to the slide rail.

[0010] As a further improvement of the present invention, the top surface of the placement plate is provided with an anti-slip layer.

[0011] Compared with the prior art, the advantages of the present invention are as follows:

[0012] The vertical shaft drives the swing arm to rotate through the bevel gear, and the horizontal groove and gear work together to make the placement plate move back and forth along the slide rail, so as to conveniently and quickly remove the innermost liquid level gauge, making it more convenient and efficient.
