Grooving machine without cutting dead angle

Abstract

The invention provides a grooving machine without a cutting dead angle, belonging to the technical field of decoration engineering, and solving the problem that the structures and variety of the existing grooving machines without the cutting dead angle are not complete. The grooving machine without the cutting dead angle comprises a case and a saw blade shield, wherein the saw blade shield comprises a fixed shield and a movable shield; the fixed shield is fixedly connected with the case, the movable shield is rotatably connected with a first rotating shaft, the first rotating shaft is fixedly connected with a second rotating shaft, and the second rotating shaft is rotatably connected with the fixed shield; and a locking structure is arranged between the movable shield and the fixed shield for ensuring positioned connection of the movable shield and the fixed shield when the fixed shield and movable shield are arranged sequentially along an arc, and also ensuring positioned connection of the movable shield and the fixed shield when the movable shield is sleeved outside the fixed shield. The grooving machine without the cutting dead angle can ensure that the grooving machine is suitable for cutting planes as well as cutting corners, i.e. the grooving machine without the cutting dead angle has the advantage of no cutting dead angle.

Description

technical field [0001] The invention belongs to the technical field of decoration engineering, and relates to a tool for decoration engineering, in particular to a slotting machine without cutting dead angle. Background technique [0002] Hydropower construction is an essential construction step for decoration projects; during the hydropower construction process, it is necessary to make grooves on the ground or walls. Traditional slotting is chiseled out by hand. With the development of society, people began to use electric hammers to assist in chiseling out the required slots; later, people proposed equipment dedicated to slotting, such as slotting machines (authorized announcement number CN201279843Y), Then the slotting efficiency is significantly improved; however, it is found in the process of use that there is a problem that the corner between the wall and the wall, and the corner between the ground and the wall cannot be cut and formed by a slotting machine.
