The side walls abut against each other; compared with the existing adjustable scraper 3 blade assembly, when the utility model adjusts the height position of the scraper 3, it is only necessary to screw the adjusting bolt 4 in the forward or reverse direction. With the cooperation of the anti-rotation member 5 and the anti-rotation strip groove 22 of the adjusting column 2, the rotation of the adjusting bolt 4 will drive the adjusting column 2 to slide upward or downward, thereby adjusting the height position of the scraper 3. The utility model is not only easier to adjust the height position of the scraper 3, but also can adjust the height position of the scraper 3 more precisely, and can be better suitable for the scraper 3 device.

[0018] The mounting block 1 is formed with an adjustment cavity 11, and the adjustment column 2 is slidably connected in the adjustment cavity 11 of the mounting block 1 along the vertical direction. A clamping elastic member 6 is sandwiched between the top of the adjustment column 2 and the top wall of the adjustment cavity 11; the clamping elastic member 6 generates a clamping force that always presses the adjustment column 2 downward, thereby eliminating the thread gap and does not generate a gap displacement error, thereby further improving the adjustment accuracy of the height position of the adjustment column 2, that is, the adjustment accuracy of the height position of the scraper 3 can be further improved.

[0019] The elastic member 6 is a spring or a plurality of elastic gaskets stacked in the vertical direction.
