[0008] The two linear slides are respectively installed on both sides of the lower end of the fixed plate, the two moving blocks are respectively installed on the driving ends of the two linear slides, the two sides of the lower end of the fixed frame are respectively connected to the two moving blocks, the clamping plate is located at the upper end of the fixed frame, and the two clamping bolts are respectively embedded in the clamping plate and both sides of the fixed frame.

[0009] Preferably, a groove is provided on one side of the upper end of the fixing frame.

[0010] Preferably, a pressing protrusion is installed at the lower end of the pressing plate.

[0011] Preferably, the scraper is fixed in the mounting groove by bolts.

[0012] Beneficial effects

[0013] The utility model provides a leather raw hide dehairing device, which has the following beneficial effects: the scraping structure and traction fixing structure adopted in this case cooperate with the provided fixed frame and the pressing plate to fully fix one end of the leather when in use, and the provided linear slide drives the leather to move on the upper end of the fixed plate.
