Further, a pair of dovetail grooves are formed in the outer wall of the inner strip, and dovetail strips penetrate through the dovetail grooves and are arranged on the inner wall of the isosceles trapezoid strips. The arrangement of the dovetail grooves and the dovetail strips can improve the stability of connection between the inner strips and the isosceles trapezoid strips.

The technical scheme has the advantages that:

compared with the prior art, the utility model firstly improves the service life of the powder scraper, secondly, through the detachable design, when the isosceles trapezoid strip is worn, the isosceles trapezoid strip is convenient to replace, and the replacement only needs to be carried out on the worn isosceles trapezoid strip, and the whole powder scraper is not needed to be replaced, thereby reducing the cost investment of enterprises and having stronger practicability.
