Description

Technical Field

[0001] The utility model belongs to the technical field of building tools, and particularly relates to a handheld wall smoothing device. Background Art

[0002] The mud trowel is also called a plastering knife. It is a tool for leveling and filling mud and plaster. The trowel is made of carbon steel, manganese steel and stainless steel. It is made of the same material as the putty knife, and consists of a blade and a handle. Since the trowel plate is easily damaged during use and has a short lifespan, the trowel column and trowel handle are relatively strong and not easily damaged. This will cause the trowel plate to be damaged, and the trowel column and trowel handle that are set together cannot be reused, resulting in overall waste.

[0003] After searching, a Chinese patent with publication number CN213868777U discloses an iron trowel, including a trowel plate, a trowel column and a trowel handle, wherein the trowel column is arranged on the trowel plate, and the trowel handle is arranged on the trowel column, a plug-in block is arranged at one end of the trowel column close to the trowel plate, a mounting block is arranged on one side wall of the trowel plate close to the trowel column, and a plug-in groove for accommodating the plug-in block is arranged in the middle position of the mounting block.

[0004] The above-mentioned smoothing device in the prior art still has some shortcomings in actual use and operation. For example, the traditional trowel uses two slides with inner recesses to clamp on both sides of the trowel column, and then uses two limit screws to limit the two sides of the slides to realize the connection between the trowel column and the upper end mounting seat of the trowel plate. However, when the trowel plate is actually replaced, this structure must use special disassembly tools to remove the screws that limit the slides to replace the corresponding trowel plate. After replacement, it is also necessary to use tools to install it, which leads to low disassembly and assembly efficiency of the trowel column and trowel plate. Utility Model Content
