A wall slotting machine

technical field

The invention belongs to the technical field of electric tools, and relates to a wall slotting machine.

Background technique

In modern interior decoration projects, in order to ensure the smoothness and beauty of the wall, all indoor wirings are buried with hidden wires, and in order to bury the lines, the wall needs to be slotted, that is, it needs to be opened at multiple locations on the wall. Wire troughs of different sizes and shapes; traditional grooving work is mostly carried out manually, but this method not only has high labor intensity, low work efficiency, poor grooving quality, but also has low operational safety performance, which is very difficult for operators. The physical injury is also greater; the wall slotting machine is widely used in indoor and outdoor decoration spring installation operations, it can be used to slot on the wall, and engineering materials such as wires and pipes can be placed in the slot, so that the After the groove is closed, the engineering materials are hidden in the wall, which is very beautiful and safe. Since the grooves required by the wall slotting machine include straight lines, arcs and various shapes of different angles, the workers have high operation intensity, so the wall is required. The surface slotting machine is convenient and labor-saving to use; in order to improve the aforementioned problems, the wall slotting machine is widely used in indoor and outdoor decoration spring installation operations. It has a casing, the back of the casing is designed with a handle, and a motor is installed in the casing , There are knives and protective covers on the head of the casing.
