Description

Technical Field

[0001] This utility model relates to the field of wall sander technology, and in particular to a wall sander for decoration. Background Technology

[0002] Utility model patent CN220881662U relates to the field of decoration equipment technology and discloses a decorative wall sanding device, including a sanding base. Two support blocks are symmetrically installed on the upper surface of the sanding base. A support frame is rotatably connected to the outer side of the two support blocks. A support rod is installed on the right side surface of the support frame. A dust collection mechanism is provided on one side of the sanding base, and an extension rod is movably installed on the outside of the support rod. A positioning mechanism is provided on the left end of the upper surface of the extension rod. This utility model uses a motor to drive the sanding disc to rotate and sand the wall surface during decoration. The exhaust fan in the dust collection mechanism draws the dust generated during sanding into the dust collection tank to prevent dust from drifting into the surrounding air and affecting the health of the workers. Pulling the mounting plate in the positioning mechanism upwards moves the positioning rod away from the positioning hole, which allows the extension rod to be moved left and right, thereby adjusting the length of the sanding device, making it convenient for workers to sand higher walls without having to climb.

[0003] The existing technology achieves the sanding effect on the wall by rotating the sanding disc at high speed. However, there is a three-dimensional right angle between the two vertical walls and the top of the wall. The circular sanding disc has certain blind spots during sanding and cannot completely sand the three-dimensional right angle, which has certain limitations. In addition, the telescopic adjustment mechanism is inconvenient in actual use. Therefore, there is a need for a wall sander for decoration to meet people's needs. Utility Model Content
