[0002] With the development of the construction field, the awareness of engineering quality is constantly improving, and the requirements for construction quality are more stringent. In the construction process of secondary structure masonry, the commonly used masonry material is concrete aerated block. Since the volume modulus of the block is fixed, it must be cut when encountering special needs of a smaller volume, so a cutting device is required.

The workers' limbs are close to the running cutting tools, which can easily cause injuries to the workers. In addition, the manual fixation and foot fixation have weak force, and the aerated blocks are prone to displacement during cutting, which affects the cutting quality of the aerated concrete blocks.

[0009] Furthermore, two lower connecting holes are provided on the top of the arch frame, and two upper connecting holes are provided on the outside of the pressure rod.
