Abstract

The invention discloses a foldable putty knife. The foldable putty knife comprises a grab handle. A storage groove is formed in the top end of an inner cavity of the grab handle. A cotton plate is fixedly installed at the bottom end of the storage groove. A fixing device located on the side surface of the storage groove is fixedly installed at the top end of the inner cavity of the grab handle. A passive device is fixedly installed on one side of an inner cavity of the fixing device. An adjusting device is fixedly installed on the side surface of the fixing device, and a gap is reserved between the passive device and the adjusting device. The bottom end of the passive device is movably connected with a bottom plate fixedly installed at the bottom of the fixing device. According to the foldable putty knife, the cotton plate is arranged, so that the effect that the top end of a scraper blade is sleeved is achieved, and the situation that the service life of the scraper blade is shortened due to the fact that the scraper blade scrapes the bottom end of the storage groove is avoided; and the fixing device is sleeved with a fixing buckle, thus, the scraper blade is folded and fixed, the situation that the scraper blade scrapes a tool bag is avoided, the putty knife is convenient to carry, and the safety of the putty knife is improved.

Description

technical field [0001] The invention relates to the technical field of construction tools, in particular to a foldable putty knife. Background technique [0002] Putty knife, also known as scraper, is one of the paint auxiliary tools, and it is also a hand tool often used by painters. It can realize scraping, shoveling, coating and filling, and is widely used in construction and life. The putty knife is composed of a blade and a handle. When the putty knife is used, the blade will bend to a certain extent. Therefore, the blade of the putty knife is relatively thin. A blade with such a thin thickness is equivalent to a blade. It is easy to put it in the tool bag It is inconvenient to carry, and sometimes you will accidentally scratch the surrounding objects, and even cut your own hands in severe cases. The safety of traditional putty knives is low, so we propose a foldable putty knife. Contents of the invention [0003] The purpose of the present invention is to provide a ...
