DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figures 1 to 3 In an embodiment of the utility model, a brick cutting tool for masonry engineering includes a base 1, a pressure rod 7 is hingedly connected to the top of the base 1 through a hinge seat 6, a handle 17 is provided at one end of the pressure rod 7 away from the hinge seat 6, and a switch 18 is installed on the handle 17, a cutter 9 is slidably penetrated through the top of the pressure rod 7, a shell 8 is fixedly connected to the top of the pressure rod 7, the top of the cutter 9 is located in the shell 8, an electromagnet 16 and a plurality of first springs 13 are installed in the shell 8 above the cutter 9, and a lifting mechanism for the cutter 9 is installed on the shell 8.

[0020] The utility model adopts the above scheme. When in use, the lifting mechanism is started to lift the cutter 9 in the shell 8 to compress the first spring 13, and the electromagnet 16 is used to adsorb the top of the cutter 9. Then, the brick 24 is placed on the base 1, and the part of the brick 24 to be cut is aligned with the cutter 9. Then, the electromagnet 16 is turned off by the switch 18. At this time, the cutter 9 will fall rapidly under the action of the first spring 13, so that the blade quickly hits the surface of the brick 24, so that the brick 24 is cut off by the instantaneous impact force. The operation is simple and convenient, the use is safe, and the accuracy of the cut size of the brick 24 can be guaranteed.

[0021] Specific combination Figure 1 In one embodiment of the utility model, the outer wall of the cutter 9 located in the shell 8 is provided with a square hole 10, and the lifting mechanism includes a reduction motor 11 fixedly mounted on the outer wall of the shell 8, and the output shaft of the reduction motor 11 is inserted into the shell 8 and fixedly connected with a cam 12, and the cam 12 is located in the square hole 10, and a plane is provided on the outer peripheral wall of the cam 12.

[0022] Start the reduction motor 11 to drive the cam 12 to rotate in the square hole 10. When the arc-shaped outer wall of the cam 12 contacts the top surface of the square hole 10, the cutter 9 can be pushed to move upward in the housing 8. After the electromagnet 16 adsorbs the top of the cutter 9, the cam 12 continues to rotate so that the plane on its outer wall is vertically facing upward. At this time, the electromagnet 16 is turned off, and the cutter 9 can fall quickly under the action of the first spring 13 to avoid interference of the cam 12 with the movement of the cutter 9.

[0023] Specific combination Figure 1In one embodiment of the utility model, a plurality of guide rods 14 are slidably provided on the top of the shell 8, the top ends of the guide rods 14 are fixedly connected to the limiting blocks 15, the bottom ends of the guide rods 14 are fixedly connected to the cutters 9, and the first springs 13 are sleeved on the corresponding guide rods 14.

[0024] By setting the guide rod 14 and the limit block 15, the movement of the cutter 9 can be guided and limited to avoid the plane on the cam 12 directly colliding with the top surface of the square hole 10 during the falling of the cutter 9, thereby protecting the reduction motor 11.

[0025] Specific combination Figure 1 and Figure 2 In one embodiment of the utility model, a cylinder 2 is detachably connected to the top of the base 1 at the corresponding position of the cutter 9, a convex strip 5 is fixedly connected to the inner wall of the cylinder 2, and the convex strip 5 is located directly below the cutter 9. The outer walls of both sides of the pressure rod 7 are installed with clamping mechanisms, and the two clamping mechanisms are symmetrically distributed on both sides of the cutter 9.

[0026] By setting the convex strip 5, the part of the brick 24 to be cut off is placed on the convex strip 5, and then the pressure rod 7 is operated to make the two clamping mechanisms clamp the parts of the brick 24 located on both sides of the convex strip 5, so that the bottom surface of the brick 24 is in a suspended state except for the part to be cut off that contacts the convex strip 5. At this time, the part to be cut off on the upper surface of the brick 24 is impacted by the cutter 9, which can make the part of the brick 24 that contacts the convex strip 5 also receive a strong reaction force, so that the brick 24 is cut off from the upper and lower surfaces to make the cross section smoother, and at the moment the brick 24 is cut off, the bricks located on both sides of the convex strip 5 will be quickly clamped in the cylinder 2 by the clamping mechanism to avoid the bricks from flying, thereby further improving safety.

[0027] Specific combination Figure 3 On the basis of the previous embodiment, further, the clamping mechanism includes a connecting seat 19 fixedly connected to the pressure rod 7, a sliding rod 20 is slidably penetrated on the connecting seat 19, the top end of the sliding rod 20 is fixedly connected to a limiting plate 21, the bottom end of the sliding rod 20 is fixedly connected to a pressure block 22, and the outer wall of the sliding rod 20 located between the connecting seat 19 and the pressure block 22 is sleeved with a second spring 23.

[0028] After the brick 24 is placed in the cylinder 2 , the pressure rod 7 is operated to rotate, so that the pressure block 22 is pressed on the surface of the brick 24 and the second spring 23 is compressed to press the brick 24 tightly against the convex strip 5 .

[0029] Specific combination Figure 1 and Figure 2In one embodiment of the utility model, a rectangular block 4 is fixedly connected to the bottom of the cylinder 2, and a rectangular hole 3 adapted to the rectangular block 4 is opened on the top of the base 1. The cooperation between the rectangular block 4 and the rectangular hole 3 facilitates the rapid disassembly and positioning installation of the cylinder 2 on the base 1, thereby facilitating the dumping of brick debris remaining in the cylinder 2.

[0030] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
