At the same time, when the rail seat 3 at the bottom of the instrument body 1 and the guide rail 4 at the top of the ruler body 5 are mutually engaged,

[0061] The springs A12 in the two sets of sliding holes 10 on the inner side of the instrument body 1 facilitate pushing the T-shaped tube 11, so that one end of the T-shaped tube 11 can extend out of the sliding hole 10 and pass through the insertion hole 13 on the surface of the rail seat 3 and be plugged into the insertion hole 13 on the top of the guide rail 4, so that the instrument body 1 can be firmly connected to the ruler body 5. Then, when the instrument body 1 and the ruler body 5 are used to measure the flatness of the wall, the two sets of support blocks 9 on the outer periphery of the ruler body 5 can be pulled, so that the two sets of support blocks 9 can pull the square rod 8, so that the square rod 8 slides in and slides out of the square tube B7, and at the same time, the square tube B7 can slide and slide out of the square tube A6, and the square tube A6 The ruler body 5 can slide and slide out from the inside of the ruler body 5, so that the length of the ruler body 5 can be extended. At the same time, in this process, the spring B23 in the vertical groove 20 inside the block 19 can push the two sets of sliding balls 21 in the vertical groove 20, so that the two sets of balls 21 can slide in opposite directions and extend from the other end of the vertical groove 20, so that the end of the ball 21 extending from the vertical groove 20 can be mutually fitted and connected with the arc-shaped hole 22 on the outer periphery of the ruler body 5, the square tube A6 and the square tube B7, so as to provide a certain locking performance between the extended square tube A6, the square tube B7, the square rod 8 and the ruler body 5, so that they will not automatically retract.

[0062] Then the staff can take the measuring device composed of the instrument body 1 and the ruler body 5 through the handle 26 on the top of the instrument body 1 to measure the flatness of the wall. At the same time, during the measurement process, the dial bodies 16 on both sides of the outer periphery of the instrument body 1 are convenient for the staff to observe the measured data, and the pointer A17 on the inner side of the dial body 16 is always kept parallel to the ruler body 5, and the pointer B18 is convenient for self-rotation, and the counterweight block 31 and the Y-shaped rod 30 cooperate with each other and transmit to each other with the pointer B18 through the horizontal axis 29, so that the pointer B18 is always kept vertical to the ground, so that when the wall is tilted, the angle between the pointer B18 and the pointer A17 will change, and when the level bubble of the instrument body 1 is not observed, the staff can clearly understand the measurement data during measurement while measuring, so that the staff can understand whether the wall of a large area is flat, and can also observe the level bubble of the instrument body 1 to judge whether the wall is flat.

[0063] After the measurement is completed, the staff only needs to push the two groups of support blocks 9 on the periphery of the ruler body 5 with force, and at this time, the ball body 21 and the arc groove are conveniently separated from each other under the action of the thrust, and at the same time, the two groups of ball bodies 21 in the vertical groove 20 are convenient to counter-press the spring B23 and retract into the vertical groove 20, so that the square tube A6, square tube B7 and square rod 8 on both sides of the periphery of the ruler body 5 can be retracted and returned to their positions, which is convenient for storage and carrying, and then the push rods 14 in the sliding holes 10 on both sides of the periphery of the instrument body 1 are pushed, so that the push rods 14 can drive the T-shaped The tube 11 slides and displaces in the slide hole 10, and the T-tube 11 and the plug hole 13 are separated from each other and retracted into the slide hole 10, and the push rod 14 and the buckle groove 15 on the outside of the slide hole 10 are mutually engaged, which is convenient for limiting the position of the retracted T-tube 11. Then the staff can push the instrument body 1, so that the rail seat 3 at the bottom of the instrument body 1 and the top guide rail 4 of the ruler body 5 are separated from each other, which is convenient for disassembly and analysis between the two. While convenient for storage, the instrument body 1 and the ruler body 5 can also be used separately.
