Construction joint surface scabbling treatment device

The utility model belongs to the technical field of building construction, and discloses a construction joint surface scabbling treatment device which comprises a base, a side opening is formed in the left side of the base, a movable block is movably connected in the side opening in a sleeved mode, a limiting block is fixedly installed on the front side of the movable block, and the outer surface of the limiting block is movably connected with the inner wall of the side opening. And a driving motor located above the base is fixedly mounted on the right side of the moving block. By arranging the brake motor, the gear and the tooth groove, due to operation of the brake motor, the gear can be driven to rotate through the rotating rod, and then due to mutual cooperation between the tooth groove and the gear, the whole moving block and the limiting block can be driven to move downwards along the inner wall of the side opening; further, the conical block gradually descends to chiseling concrete at the construction
