[0024] In the above structure, by means of the steel wire rope 14 and the rubber ring structure, when the user needs to perform verticality measurement on the wall, the steel wire rope 14 can be pulled to make the rubber ring close to the fixing rod 11, so that the user can sleeve the rubber ring on the fixing rod 11, thereby allowing the positioning shell 23 to shrink into the square groove, so that the user can insert the fixing plate 12 into the docking groove 22, so that the infrared sensing effect of the infrared transmitter 3 and the infrared receiver 13 can be used to detect the verticality of the wall during the lifting process of the lifting plate 4, thereby ensuring the normal use of the device.

[0029] In a preferred embodiment, a circular hole is formed on the inner wall of the mounting groove 20 , and the inner wall of the circular hole is slidably connected to the outer wall of the sleeve 18 .

[0030] In the above structure, through the set circular hole and sleeve 18 structure, the user can measure the flatness of the wall when the positioning shell 23 contacts the wall, and can detect the verticality of the wall when the fixing plate 12 contacts the wall.

[0032] In the above structure, by setting up a pressure sensor and a controller structure, the device uses the pressure sensor to measure the extrusion force exerted on the positioning shell 23 during operation, thereby achieving the effect of measuring the flatness of the wall, and the controller can facilitate the user to control the motor 7 to make the lifting plate 4 perform lifting operations, thereby detecting the verticality of the wall, thereby improving the automation of the device.

[0033] Working principle: First, after the user assembles the device, fix the positioning plate 1 on the ground, and then pull the wire rope 14 to make the rubber ring fit with the fixing rod 11, so that the sleeve 18 compresses the pressure spring 17 to allow the positioning shell 23 and the roller 24 to be stored in the square groove, and then insert the fixing plate 12 into the docking groove 22, so that the positions of the infrared transmitter 3 and the infrared receiver 13 correspond to each other, and then the lifting plate 4 is raised to drive the fixing plate 12 to rise and fall together. During the rising process of the lifting plate 4, the rubber ring cannot be deformed due to the reaction force of friction. When there is a gap between the wall tilt and the fixing plate 12, the reaction force disappears, and the pressure spring 17 The elasticity will push the positioning shell 23 to generate a thrust on the fixing plate 12, and the rubber ring will be pulled and deformed, so that the fixing plate 12 continues to contact with the wall, and the infrared transmitter 3 will be misaligned with the infrared receiver 13, proving that the wall is tilted, thereby achieving the effect of detecting the verticality of the wall. After the detection, the user can put the rubber ring on the fixing rod 11, so that the fixing plate 12 will not be affected by the positioning shell 23 and is always firmly inserted in the docking groove 22. The positioning shell 23 is brought into contact with the wall by the descent of the lifting plate 4, and the flatness of the wall is detected by using the pressure detection result of the pressure spring 17, thereby improving the function of the device.
