[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0023] Example 1: As Figures 1 to 3 As shown, a building leveling ruler includes a scraper 1. Two rails 2 are fixedly connected to both sides of the top center of the scraper 1. Each rail 2 has a locking hole 3 in its center. A mating plate 4 is inserted into the inner wall of both rails 2. A guide hole 14 is provided in the center of the mating plate 4. Spring baffles 10 are slidably connected to both sides of the inner wall of the guide hole 14. An inclined pin 5 is fixedly connected to the center of one side of each of the two spring baffles 10. Both inclined pins 5 penetrate through the center of the two sides of the outer wall of the mating plate 4, guiding the direction of the process. A thrust spring 13 is provided at the center of the inner wall of the hole 14. Under the push of the thrust spring 13, the two spring baffles 10 push the inclined pin 5 out of the outer wall of the docking plate 4. The two inclined pins 5 are respectively engaged and fixed with the locking holes 3 of the two locking rails 2. A rotating seat 7 is rotatably connected at the center of the top surface of the docking plate 4. A connecting block 8 is rotatably connected at the center of the top surface of the rotating seat 7. A push rod 9 is rotatably connected to the top of the connecting block 8. The rotation direction of the push rod 9 and the connecting block 8 is perpendicular to the rotation surface of the connecting block 8 and the rotating seat 7.

[0024] As an optional technical solution of this utility model, a guide strip hole 12 is provided in the middle of one side of the docking plate 4. The guide strip hole 12 is connected to the inner wall of the guide hole 14. A handle rod 11 is fixedly connected to the center of one side of the spring baffle 10. The handle rod 11 passes through the guide strip hole 12 and extends out of the outer wall of the docking plate 4. By pulling the two handle rods 11, the two inclined locking pins 5 are disengaged from the locking hole 3, and the docking plate 4 can be pulled away from the locking rail 2 to realize the disassembly and replacement of the scraper 1.

[0025] As an optional technical solution of this utility model, the length of the guide strip hole 12 is adapted to the length of the docking plate 4, and the length of the thrust spring 13 after reset is adapted to the length of the inner wall of the guide hole 14, so that the thrust spring 13 can press against the two inclined pins 5.

[0026] As an optional technical solution of this utility model, a baffle 6 is fixedly connected to one end of the scraper 1 and the two locking rails 2. When the inclined locking pin 5 is locked with the locking hole 3, one side of the docking plate 4 is pressed against the baffle 6. The positioning of the baffle 6 prevents the docking plate 4 from being pushed out of the locking rail 2 from one end of the locking rail 2.

[0027] As an optional technical solution of this utility model, the thickness of the mating plate 4 is adapted to the height of the inner wall of the rail 2, the width of the mating plate 4 is adapted to the length of the rail 2, and the length of the mating plate 4 is adapted to the distance between the inner walls of the two rails 2, so that the mating plate 4 and the rail 2 are tightly mated and the mating plate 4 is prevented from shaking.

[0028] A type of building leveling ruler works on the following principle:

[0029] 1) Horizontal rotation can be achieved through the connection of the rotating seat 7, left and right rotation can be achieved through the rotation of the connecting block 8 and the rotating seat 7, and forward and backward rotation can be achieved through the rotation of the push rod 9 and the connecting block 8. This allows the push rod 9 and the scraper 1 to be flexibly connected at multiple angles. When leveling, the construction personnel can push the scraper 1 to move more flexibly.

[0030] 2) By pulling the two handles 11, the two inclined pins 5 are disengaged from the locking holes 3, and the docking plate 4 can be pulled out of the locking rail 2, so as to disassemble and replace the scraper 1.

[0031] In summary, this building leveling ruler can achieve horizontal rotation through the connection of the rotating seat 7, left and right rotation through the rotation of the connecting block 8 and the rotating seat 7, and forward and backward rotation through the rotation of the push rod 9 and the connecting block 8. This allows the push rod 9 to achieve flexible multi-angle connection with the scraper 1. During leveling, construction workers can move the scraper 1 more flexibly, improving its practicality. By pulling the two handle rods 11, the two inclined locking pins 5 can be disengaged from the locking holes 3, which can then pull the connecting plate 4 away from the locking rail 2, enabling the scraper 1 to be disassembled and replaced.
