Tissue spreading machine with easily-replaced scraper

The tissue spreading machine comprises a rotating shaft, an installation mechanism is arranged in the rotating shaft, and the installation mechanism comprises a pull rod, a transverse column, a clamping block, a transverse rod, a spring, a connecting block and a vertical column. According to the tissue spreading machine with the scrapers easy to replace, through cooperation of the pull rod, the transverse column, the clamping blocks, the transverse rod, the springs, the connecting block and the vertical column, the pull rod is pulled, the pull rod drives the pin shaft to rotate so as to drive the transverse column to rotate, and when the two ends of the transverse column and the clamping blocks on the two sides drive the transverse rod to slide in the connecting block, the springs are compressed, and the clamping blocks at the two ends leave the upper and lower scrapers; when the scraper is replaced, the purpose of replacing the scraper blade through the two springs is achieved, operation is very easy, the re
