[0007] One end of the corner scraper is at a flat angle, and the other end is at a sharp angle. A fixing seat is provided on the scraper on one side of the inner angle line of the sharp end of the corner scraper, and a connecting hole is provided on the fixing seat;
[0008] One end of the handle is connected to a ratchet device, and the ratchet device is sleeved with a fixing seat; the connecting head of the ratchet device is adapted to be embedded in a connecting hole on the fixing seat.
[0009] A limiting through hole is provided on the side surface of the fixing seat, and a limiting bolt is screwed into the limiting through hole.
[0010] The handle neck at the connection between the handle and the ratchet device is in the shape of a Chinese character "乁", and the handle rotates along with the rotation direction of the ratchet device.
[0011] The ratchet device is provided with a locking button and an adjusting rod. The locking button adjusts the connecting head of the ratchet device to rotate forward and reverse; the adjusting rod adjusts the connecting head of the ratchet device to move axially.
[0012] Beneficial effects of the utility model:
[0013] 1. The angle scraper is combined with a handle with a ratchet device, featuring a simple structure and easy assembly. There is no need to carry two angle tools, namely the external angle tool and the internal angle tool, which is convenient for carrying. After use, only one angle scraper needs to be cleaned, which is convenient for cleaning.
[0014] 2. The ratchet device is adopted to convert the angular position between the handle and the angle scraper, and by changing the angle, the operations of scraping ash on external angles and internal angles can be achieved. The operation is simple, which improves the working efficiency of the ash scraping operation. BRIEF DESCRIPTION OF THE DRAWINGS
