By utilizing the attraction between the opposite poles of the installation magnetic strip and the fixed magnetic strip, the pulling plate and the U-shaped plate can be stably connected, which is convenient for the staff to use.

[0024] By utilizing the sliding effect between the sliding rod and the sliding sleeve, the height of the U-shaped plate can be slidably adjusted, so that the device can adapt to ceilings of different heights.

[0045] After the point setting on the ceiling is completed, the pulling plate 4 is disassembled. At this time, according to the action of the torsion spring 4015, the pulling rope 4016 can be elastically restored to the initial position, so that the pulling plate 4 is restored to the initial position, which can drive the installation block 4017 to contact one side of the U-shaped plate 1, so that the installation switch 4019 is squeezed to turn off the laser locator 403. The laser locator 403 can be turned on and off by squeezing and opening the installation switch 4019, so that the staff does not need to manually turn the laser locator 403 on and off, thereby improving the staff's use efficiency of the device. By using the effect of the attraction between the opposite poles of the installation magnetic strip 4018 and the fixed magnetic strip, the pulling plate 4 can be stably connected to the U-shaped plate 1, which is convenient for the staff to use it;

[0046] By utilizing the sliding effect between the sliding rod 5 and the sliding sleeve 6, the height of the U-shaped plate 1 can be slidably adjusted, so that the device can adapt to ceilings of different heights. The attraction between the opposite poles of the two sliding magnetic strips is utilized to improve the sliding limiting effect between the sliding rod 5 and the sliding sleeve 6.

[0049] Step 1: When positioning and installing the equipment installed on the ceiling, the staff first installs the pulling plate 4 on the ceiling at the desired location through the mounting bolts 402, and then winds the finished drawing around the outer wall of the winding roller 3;

[0050] Step 2: After the drawings and the pulling plate 4 are installed, the sliding sleeve 6 is pulled to drive the U-shaped plate 1 to pull, so that the drawings can be pulled and attached to the top of the ceiling. When the U-shaped plate 1 is pulled, the pulling rope 4016 can be pulled according to the fixing effect of the pulling plate 4, so that the installation block 4017 is separated from the U-shaped plate 1, and the squeezing effect between the installation switch 4019 and the U-shaped plate 1 is lost, and the laser locator 403 is turned on at this time;

[0051] Step 3: After the point setting on the ceiling is completed, the pulling plate 4 is removed. At this time, according to the action of the torsion spring 4015, the traction rope 4016 can be elastically restored to the initial position, so that the pulling plate 4 is restored to the initial position, which can drive the installation block 4017 to contact one side of the U-shaped plate 1, so that the installation switch 4019 is squeezed.

[0052] Furthermore, the present design application is used to quickly locate points on the top of the ceiling. The staff only needs to install the pulling plate 4, and then pull the sliding sleeve 6 on the ground to pull the drawing. There is no need for the staff to frequently use ladders to assist the staff in positioning the drawings on the ceiling. Correspondingly, it is convenient for the staff to locate points on the ceiling, thereby improving the work efficiency of the staff in decorating the ceiling.
