Description

Technical Field

[0001] The utility model relates to the field of construction tools, in particular to a portable brick cutter. Background Art

[0002] Foam bricks have excellent compressive properties: compressive strength greater than 0.5 MPa, with a maximum strength exceeding 10.5 MPa. They are crack-resistant and have a long service life. Foam bricks are also made from a variety of raw materials. Foam cement bricks are made by mixing small foam particles with cement. They are lightweight, heat-insulating, sound-insulating, and fire-resistant. Their small diameter significantly reduces costs, making them ideal for non-load-bearing walls. Bricks are generally fixed in size, but in certain building locations, the size of the bricks needs to be changed. In these cases, a brick cutter is used to ensure that the bricks are flat and the right size after cutting.

[0003] Existing brick cutters are divided into manual and electric types according to the power source. Since electric brick cutters need to be driven by power and generate a lot of noise and dust, manual brick cutters are mostly used to cut bricks on construction sites to ensure the convenience of using brick cutters. However, when using existing manual brick cutters, in order to ensure the stability of the blades, the blades are mostly connected to the bracket, but the brick cutters can only cut right-angled bricks, so people need to use brick cutters to correct the bricks into inclined-angle bricks, which greatly reduces the speed of people's bricklaying construction.
