[0038] As a further technical solution for the implementation of this scheme, a plurality of first positioning platforms 32 and second positioning platforms 86 are provided, and the first positioning platforms 32 and second positioning platforms 86 are both adapted to the vertical rod 31. Through the above arrangement, the vertical rod 31 can be stably limited;

[0039] As a further technical solution of this scheme, the bottom end of the vertical rod 31 is arranged in an arc shape, the guide rod 34 is arranged outside the first spring 33, the upper ends of the first spring 33 and the guide rod 34 are fixedly connected to the inside of the rangefinder body 1, and the vertical rod 31 and the block 82 correspond one to one. Through the above arrangement, the vertical rod 31 can be assisted to reset, and at the same time, it can be limited by the block 82;

[0040] As a technical solution for further implementation of this scheme, the pressing member 4 is U-shaped, the pressing member 4 and the fixing plate 7 and the lower end of the rangefinder body 1 are all slidably connected, and both ends of the pressing member 4 are installed on the inner side of the third spring 11. Through the above arrangement, the movable frame 81 can be controlled;

[0041] As a technical solution for further implementation of this scheme, a laser hole 2 is opened at the upper end of the rangefinder body 1, and the laser radar 9 and the electromagnet 10 installed inside the rangefinder body 1 are arranged on the same vertical line as the center point of the laser hole 2. Through the above arrangement, when the rangefinder body 1 is tilted, it can be shielded by the shielding plate 51;

[0042] As a technical solution for further implementation of this scheme, the electromagnet 10 is arranged at the lower end of the shielding mechanism 5, and the shielding mechanism 5 includes a shielding plate 51, the upper end of the shielding plate 51 is a circular hole 52, and the lower end of the shielding plate 51 is fixedly connected to a cone block 53, and the middle of the shielding plate 51 is rotatably connected to a rotating shaft 6, and the rotating shaft 6 is fixedly connected to the inside of the rangefinder body 1. The center point of the electromagnet 10 and the center point of the rotating shaft 6 are arranged in the same vertical plane, and the distance between the electromagnet 10 and the cone block 53 is 1 cm. The cone block 53 is made of iron, and the shielding plate 51 can be quickly positioned when the shielding plate 51 is tilted in the rangefinder body 1;

[0043] As a further technical solution of this scheme, the block 82 is installed inside the square groove 84, and the two ends of any block 82 are fixedly connected with a slider 87. The block 82 is closely attached to the first positioning platform 32 fixedly connected to the outer side of the vertical rod 31 through the second positioning platform 86. Through the above arrangement, the block 82 can be stably limited.

[0044] As a further technical solution of this solution, the angle between the fixing plate 7 and the vertical rod 31 is 90°, the upper end of the vertical rod 31 is hollowed out, and the lower third of the first spring 33 is arranged at the hollowed-out position of the upper end of the vertical rod 31. Through the above arrangement, the vertical rod 31 can be stably limited.

[0045] Workflow: Step I: Place the bottom of the device at the bottom of the window installation hole where the distance measurement is required: Place the lower end of the distance measuring device at the location where the window is installed to measure the width and length of the window;

[0046] Step II: Positioning the device: During the placement process, the device is pressed down to keep the device horizontal by squeezing the auxiliary head 3. When the vertical rods 31 come into contact with the uneven surface of the window installation location, the different squeezing degrees of different vertical rods 31 can achieve the overall adjustment of the device;

[0047] In this process, the vertical rod 31 can be positioned by contacting the first positioning platform 32 and the second positioning platform 86 during the movement of the vertical rod 31, thereby being applicable to different contact surfaces and improving the accuracy of the measurement;

[0049] If no laser is emitted from the laser hole 2, it means that the rangefinder body 1 is not kept level, and the placement of the entire device needs to be adjusted again. The operating principle of the shielding mechanism 5 is:

[0050] When the rangefinder body 1 is not placed horizontally enough, the shielding plate 51 tilts, causing the circular hole 52 to be misaligned with the laser radar 9, and light cannot be emitted from the laser hole 2. The electromagnet 10 is mainly used to prevent the shielding plate 51 from swinging frequently, making it difficult to cause the circular hole 52 to be misaligned with the laser hole 2 when the rangefinder body 1 is used;

[0051] Step IV: Storage after measurement: After the measurement is completed, the pressing member 4 is pressed to move toward the inside of the rangefinder body 1. After the pressing member 4 is pressed, the movable frame 81 is displaced to separate the block 82 from the vertical rod 31, and then the vertical rod 31 is reset under the drive of the first spring 33 for the next use.
