[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The structure of the present invention is scientific and reasonable, and it is safe and convenient to use: 1. A wall vertical measurement mechanism is provided. By the tension spring pushing the cushion ring, the sliding rod and the fixed shaft to move, the side support plate drives the frame, the positioning block and the roller to fit with the wall. Then, the hydraulic cylinder pushes the lifting rod and the lifting plate to rise, and at the same time drives the frame, the positioning block and the roller to rise along the wall. And because of the elasticity of the tension spring, it always supports the frame, the positioning block and the roller, maintaining the fitting degree between the roller and the wall; In addition, when the frame ascends, the traction rope is pulled, forcing the rotating rod to pay out the traction rope, increasing the length of the traction rope, facilitating the ascent of the lifting plate, enabling the inclination detection of the entire wall at different heights, improving adaptability. At the same time, utilizing the characteristic of the scroll spring to contract, it drives the rotating rod to rotate and wind up the traction rope, keeping the traction rope taut. Thus, it is convenient for the frame to pull the side support plate to rotate and incline through the traction rope. When the side support plate inclines, it pushes the sliding rod to slide inside the sleeve, and simultaneously drives the sleeve and the limit plate to slide along the positioning rod, which not only facilitates the rotation and inclination of the side support plate but also ensures the support for the side support plate, guaranteeing the effect of the side support plate fitting with the wall. In addition, when the side support plate rotates and inclines, through the cooperation of the sliding of the traction plate and the extension frame, it pushes the dial to rotate along the outer side of the bushing, making the rotation angle of the dial equal to the inclination angle of the wall. Then, due to the gravity of the plumb bob itself, the plumb line is pulled vertically downward, driving the swing rod and the pointer to rotate, forcing the pointer to always be perpendicular to the horizontal plane, facilitating the observation of the rotation angle of the dial, improving the convenience of detection. In addition, the rotating pin pushes the pressing block downward to tighten the plumb line, enabling the plumb bob to remain stable when not in use, preventing shaking and damaging the device.

[0015] 2. A wall vertical measurement mechanism is provided. The support spring pushes the U-shaped plate to ascend, driving the top plate to rotate along the fixed plate, making the top plate fit with the ceiling. During the ascent of the U-shaped plate, it drives the telescopic rod to extend, and simultaneously pushes the sliding plate to slide above the lifting plate, which not only facilitates the rotation of the top plate but also maintains the supporting effect of the telescopic rod on the U-shaped plate and the top plate, facilitating the fit of the top plate with the ceiling and improving the stability of the top plate. In addition, through the cooperation of the vertical plate, the rotating frame, the movable block and the connecting rod, it is convenient for the top plate to drive the movable plate to slide synchronously at one end of the fixed frame when the top plate ascends, facilitating the detection of ceilings at different heights, improving adaptability. When the top plate rotates and fits with the inclined ceiling, it drives the two U-shaped plates to move in opposite directions. Then, through the cooperation of the cushion plate, the movable rod and the fixed cylinder, it pushes the movable plate, the pressing plate and the vertical plate to ascend and descend, making the two vertical plates move in opposite directions. At the same time, the anti-deviation rod is used for limiting to prevent the pressing plate and the vertical plate from deviating. In addition, when the vertical plates move in opposite directions, it drives the movable block to slide inside the rotating frame through the connecting rod, and pushes the rotating frame and the semi-circular scale plate to rotate. At the same time, the rotation angle of the semi-circular scale plate is equal to the inclination angle of the ceiling. Observe the position of the laser emitted by the laser emitter on the semi-circular scale plate and read the inclination angle of the ceiling, facilitating the detection.

[0016] In summary, through the wall vertical measurement mechanism, it is convenient to conduct overall detection on walls of different heights, improving the applicability. At the same time, during the process of testing the wall verticality, the horizontal detection mechanism is used to synchronously detect the ceiling of the house, improving the detection convenience, facilitating the simultaneous detection of the wall and the ceiling, enhancing the detection efficiency, and saving time.

[0022] Working principle and usage process of the present invention: First, the tester pushes the trolley 1 to move to the edge of the wall, and then utilizes the telescopic property of the tension spring 310 to push the cushion ring 309, the sliding rod 308 and the fixed shaft 311 to move, thereby pushing the side support plate 313, the frame 323, the positioning block 324 and the roller 325 to move, forcing the roller 325 to closely fit against the wall surface. Then, the tester starts the hydraulic cylinder 301 to make the lifting rod 302 push the lifting plate 303 to rise, and the lifting plate 303 drives the frame 323, the positioning block 324 and the roller 325 to rise along the wall through the cooperation of the sleeve 307, the sliding rod 308 and the fixed shaft 311. Then, due to the elasticity of the tension spring 310, when the wall is inclined, it still pushes the frame 323, the positioning block 324, the roller 325, the fixed shaft 311 and the sliding rod 308 to move inside the sleeve 307, so that the roller 325 remains in contact with the wall; In addition, during the rising process of the frame 323, the traction rope 320 is pulled, forcing the rotating rod 318 to pay out the traction rope 320, increasing the length of the traction rope 320, facilitating the rising of the lifting plate 303, and enabling the overall inclination detection of walls at different heights, improving the adaptability. When the frame 323 descends, by utilizing the contraction property of the volute spring 319, it drives the rotating rod 318 to rotate and wind up the traction rope 320, ensuring the tension of the traction rope 320. Furthermore, it facilitates the frame 323 to pull the side support plate 313 to rotate and incline along one end of the extension plate 312 through the traction rope 320. When the side support plate 313 inclines, it pushes the sliding rod 308 to slide inside the sleeve 307, and at the same time drives the sleeve 307 and the limiting plate 306 to slide along the positioning rod 305, which not only facilitates the rotation and inclination of the side support plate 313 but also ensures the support for the side support plate 313, guaranteeing the fitting effect between the side support plate 313 and the wall; Next, when the side support plate 313 rotates and inclines, it makes the traction plate 336 slide and cooperate with the extension frame 335 to push the dial 333 to rotate along the outside of the bushing 332, so that the rotation angle of the dial 333 is equal to the inclination angle of the wall. Then, due to the gravity of the plumb bob 329 itself, the plumb line 328 is pulled vertically downward, further driving the swing rod 327 and the pointer 334 to rotate, forcing the pointer 334 to always be perpendicular to the horizontal plane, facilitating the tester to observe the rotation angle of the dial 333 and providing convenience for detection. In addition, the rotating bolt 331 pushes the pressing block 330 to descend to tighten the plumb line 328, so that the plumb bob 329 can remain stable when not in use; Next, when the lifting plate 303 ascends, it pushes the top plate 402 to ascend through the fixed plate 401, forcing the top end of the top plate 402 to closely fit with the ceiling of the house. At the same time, due to the telescopic property of the support spring 406, it pushes the U-shaped plate 403 to ascend, thereby driving the top plate 402 to rotate along the fixed plate 401. When the ceiling is inclined, the tightness of the fit between the top plate 402 and the ceiling is still maintained. And during the ascent of the U-shaped plate 403, it drives the telescopic rod 404 to extend and drives the sliding plate 405 to slide above the lifting plate 303, maintaining the supporting effect of the telescopic rod 404 on the U-shaped plate 403 and the top plate 402, facilitating the fit between the top plate 402 and the ceiling; Next, when the lifting plate 303 drives the top plate 402 to ascend, through the cooperation of the vertical plate 412, the rotating frame 414, the movable block 415 and the connecting rod 416, it drives the moving plate 413 to slide synchronously at one end of the fixed frame 2. And when the top plate 402 rotates to fit with the inclined ceiling, the two U-shaped plates 403 on the top plate 402 move in opposite directions. At the same time, through the cooperation of the cushion plate 407, the movable rod 408 and the fixed cylinder 410, it pushes the movable plate 409 to slide up and down inside the lifting plate 303, and then drives the pressing plate 411 and the vertical plate 412 to ascend and descend, causing the two vertical plates 412 to move in opposite directions, and then being limited by the anti-deviation rod 419 to prevent the pressing plate 411 and the vertical plate 412 from deviating. Finally, after the two vertical plates 412 move in opposite directions, the connecting rod 416 drives the movable block 415 to slide inside the rotating frame 414, thereby pushing the rotating frame 414 to rotate at one end of the moving plate 413, driving the semi-circular scale plate 418 to rotate. At the same time, because the rotation angle of the semi-circular scale plate 418 is equal to the inclination angle of the ceiling, then the laser emitted by the laser emitter 417 irradiates on the semi-circular scale plate 418, and the inclination angle of the ceiling is read by observing the position of the laser, completing the detection.
