Abstract
A putty scraper is provided, which includes a sealing piece and a positioning structure provided on the sealing piece. The sealing piece has a sealing state when it is fixed on the positioning structure and an unlocking state when it is detached from the positioning structure. In the sealing state, one end of the sealing piece blocks an end of a gap and prevents a blade from being detached from a handle at the end of the gap. In the unlocking state, the end of the gap is exposed. When it is necessary to extract or replace the blade, the sealing piece is pushed by hand and a positioning block is detached from a positioning groove, and then the sealing piece is rotated to expose the end of the gap. At this time, the blade can be extracted out from the end of the gap.
