It has the advantages of light weight, heat preservation, sound insulation, fire resistance, and earthquake resistance. It is widely used in the exterior walls, interior walls, partition walls, floors and roofs of buildings.

[0003] Aerated blocks are of fixed size during production and are cut according to demand during use. Traditional cutting methods in the prior art usually use an axe or a saw to cut aerated blocks. However, when workers use an axe or a saw to cut aerated blocks, due to the large size of the aerated blocks, workers need to turn the blocks over and over and cut different sides of the aerated blocks, resulting in low cutting efficiency of the aerated blocks. In addition, errors are prone to occur in cutting on multiple sides, resulting in the cutting grooves on different sides of the aerated blocks not being on the same horizontal plane, which in turn causes the fracture surface of the aerated blocks to be uneven. Therefore, how to design an auxiliary tool for cutting aerated blocks has become a problem that we currently need to solve. Summary of the Invention

The top of the angle iron 2 is fixedly connected to the connecting block 9, and the outer wall of the connecting block 9 is slidably connected to the frame 10. The inside of the connecting block 9 is slidably connected to the fixed block 11, and an inclined surface 12 is provided on one side of the fixed block 11. A locking piece 13 is fitted on one side of the inclined surface 12. The locking piece 13 is rotatably connected to the inside of the fixed block 11. The locking piece 13 is arranged on the top of the aerated block 1, and the fixed block 11 is against the inside of the frame 10. The outer wall of the connecting block 9 is fixedly connected to the scale rod 14, and the outer wall of the frame 10 is provided with a scale 15.

[0017] like Figures 1 to 4As shown, the cutting assembly includes a connecting member 16 and a handle 17 fixedly connected to the top of the frame 10, the connecting member 16 is fixedly connected to the handle 17, the connecting member 16 is rotatably connected to the inside of the connecting member 16, the outer wall of the pressure rod 18 is slidably connected to the connecting sleeve 19, the outer wall of the connecting sleeve 19 is rotatably connected to the first L-shaped rod 20, the first L-shaped rod 20 is slidably connected to the inside of the connecting member 16, one end of the first L-shaped rod 20 is fixedly connected to the main cutting knife 21, the bottom of the first L-shaped rod 20 is slidably connected to the second L-shaped rod 22, the outer wall of the second L-shaped rod 22 is fixedly connected to the slider 23, an inclined slide groove 24 is provided inside the connecting member 16, the slider 23 is slidably connected to the inside of the inclined slide groove 24, a return spring 25 is fixedly installed inside the connecting member 16, the top of the return spring 25 is fixedly connected to a sliding piece 26, the sliding piece 26 is arranged at the bottom of the second L-shaped rod 22, the sliding piece 26 is slidably connected to the inside of the connecting member 16, and one end of the second L-shaped rod 22 is fixedly connected to the auxiliary cutting knife 27.

[0018] Working principle: When the staff needs to cut the aerated block 1, first adjust the position of the angle iron 2 at the bottom of the frame 10 according to the required cutting length, and get the exact length through the scale rod 14 and the scale 15. Then the staff can put the angle iron 2 against a corner of the aerated block 1, let the aerated block 1 relatively squeeze the locking piece 13, make the locking piece 13 rotate and push the fixing block 11 to slide along the inside of the connecting block 9 through the inclined surface 12, let the fixing block 11 fix the frame 10, so that the relative position of the angle iron 2 and the frame 10 is fixed, and then the staff can turn the knob 8 so that the knob 8 drives the bidirectional threaded rod 4 to rotate through the connecting rod 7, so that the bidirectional threaded rod 4 passes through the screw thread. The groove drives the two sliding members 5 to slide along the inside of the square tube 3 and approach each other, so that the sliding members 5 drive the clamping pieces 6 to clamp on both sides of the aerated block 1, and fix the angle iron 2 on the aerated block 1, so as to achieve the effect of quickly adjusting the length of the aerated block 1 cut by the tool and fixing the tool after the cutting length is adjusted on the aerated block 1. The staff does not need to hold the tool with his hand, freeing one hand of the staff, so that the staff can apply pressure to the pressure rod 18 with both hands, thereby improving the cutting efficiency of the aerated block 1 and making it convenient for the staff to use. Through the cooperation of the main cutting knife 21 and the auxiliary cutting knife 27, grooves on the same horizontal plane can be cut on different sides of the aerated block 1, thereby improving the flatness of the fracture surface of the aerated block 1; Furthermore, when the staff has finished fixing the tool, the staff can press the pressure rod 18 so that the pressure rod 18 applies pressure to the first L-shaped rod 20 through the connecting sleeve 19, thereby causing the first L-shaped rod 20 to slide down along the inside of the connecting piece 16. The descent of the first L-shaped rod 20 will drive the main cutting knife 21 to cut the aerated block 1 from the top. At the same time, the descent of the first L-shaped rod 20 will push the second L-shaped rod 22 to descend together, causing the second L-shaped rod 22 to slide along the inside of the inclined slide groove 24 through the slider 23 and pass through the slider 23. The return spring 25 squeezes the sliding piece 26 to shrink, and the slider 23 slides along the inside of the inclined slide groove 24, which causes the slider 23 to pull the second L-shaped rod 22 to move in the direction of the pressure rod 18, so that the second L-shaped rod 22 pulls the auxiliary cutting knife 27 to cut the aerated block 1 from the side, so that the strength of the position where the groove is cut out of the side of the aerated block 1 is reduced, so that when the aerated block 1 is broken later, it will be broken first from the weak position of the side groove position, so that the fracture surface of the aerated block 1 is as flat as possible, avoiding the occurrence of uneven fracture surface. The second L-shaped rod 22 is pushed up by the return spring 25, and the second L-shaped rod 22 is pushed up along the inner part of the inclined slide groove 24 through the slider 23 and reset, so that the auxiliary cutting knife 27 is reset, and then the second L-shaped rod 22 pushes the first L-shaped rod 20 to reset, so that the first L-shaped rod 20 drives the main cutting knife 21 and the connecting sleeve 19 to reset. The reset of the main cutting knife 21 will stop cutting the aerated block 1, and the reset of the connecting sleeve 19 will push the pressure rod 18 to reset, so that the staff stops applying force to the pressure rod 18 and automatically resets, returning to the initial state, waiting for subsequent work to continue, and avoiding the situation where the auxiliary cutting knife 27 blocks the installation of the tool due to position reasons when the tool is installed; Furthermore, when the staff has completed cutting the aerated block 1, the staff can rotate the knob 8 in the opposite direction, so that the knob 8 drives the bidirectional threaded rod 4 to rotate and reset through the connecting rod 7, and the bidirectional threaded rod 4 drives the clamping piece 6 to stop clamping and fixing the aerated block 1 through the sliding member 5. At this time, the staff can separate the tool from the aerated block 1, and can rotate and reset the locking member 13, so that the aerated block 1 and the angle iron 2 can slide through the connecting block 9. At this time, the tool is completely reset and can wait for the next work.
