The present utility model will be further described in detail below with reference to the drawings and detailed description for the purpose of enabling those skilled in the art to better understand the aspects of the present utility model.

A scraping tool comprises a holding handle 2, a scraping head 1 and a scraping knife 3; one end of a holding handle 2 is detachably sleeved on the scraping head 1 and is used for trowelling the foaming material; the scraper 3 is arranged at the other end of the handle 2 and is used for cleaning foaming materials.

The scraping tool is used for uniformly smearing the foaming material around the window and the gate, and has the function of ensuring the surface to be flat, compacted and filled before foaming is completely cured, so that the hidden danger of ventilation and water leakage caused by poor sealing performance due to the fact that the foaming surface layer is damaged in a plastering stage is avoided.

The size of the scraping head 1 is not limited, and the scraping head 1 is detachably sleeved on the handle 2, so that a user can conveniently replace the scraping head 1 with different sizes according to the sizes of corners of different doors and windows, and the application range of the scraping tool is wider.

The shapes of the scraping head 1 and the scraping blade 3 are not limited, and the scraping head can be diamond, rectangle and the like, so long as the front end of the scraping head 1 is not sharp, and the material of the scraping head 1 is generally rubber.

In some embodiments, the spatula 3 is triangular in cross-section, with the tip of the triangle disposed away from the grip handle 2.
