[0043] Working principle: Before using this laser rangefinder with anti-collision function, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Fig.11As shown, first, by utilizing the characteristics of the sliding connection between the mounting slider 103 and the mounting slot 102, the protective cover 104 is sleeved on the outer side of the mounting bracket 101, so as to install and protect the laser rangefinder body 130 inside the mounting bracket 101, and the locking bevel 128 at the end of the unlocking latch 127 can be used to realize the card and connection between the protective cover 104 and the unlocking latch 127, so as to realize the rapid installation and fixation of the protective cover 104.

By rotating the second fixed turntable 111 and under the action of the spiral slot 112 inside the second fixed turntable 111, the spiral slider 113 is moved in The spiral slide groove 112 slides inside, and the spiral slider 113 drives the positioning slide rod 109 to slide inside the fixed slide groove 108.

[0044] Secondly, by utilizing the elastic force of the first spring body 118 and the second spring body 122, the clamping rotating plate 119 can slide inside the clamping slide groove 117, so that the clamping rotating arm 120 and the clamping hook 121 rotate and engage with the mounting engaging grooves 131 on both sides of the laser rangefinder body 130, thereby fixing the laser rangefinder body 130. When the laser rangefinder body 130 needs to be disassembled, the clamping rotating arm 120 and the clamping hook 121 can be manually rotated to achieve the fixation. The disassembly of the laser rangefinder body 130 is convenient for repairing and replacing the laser rangefinder body 130. When the laser rangefinder body 130 is used to measure the distance in the vertical direction, the positioning sliding rod 109 is separated from the fixing hole 115 by rotating the second fixed turntable 111. Under the action of the counterweight block 132 at the bottom of the laser rangefinder body 130, the laser rangefinder body 130 can always be kept in a vertical state, which is convenient for adjusting the angle of the laser rangefinder body 130 and improving the accuracy of measurement.
[0045] Finally, by utilizing the characteristic of the first adjusting threaded rod 201 being threadedly connected with the threaded turntable 204, the first adjusting threaded rod 201 is rotated on the internal thread of the threaded turntable 204, so that the first adjusting threaded rod 201 drives the lifting and lowering rotating disk 205 to move upward and downward. At the same time, under the action of the second rotating support 213 and the third rotating support 215, the second rotating rod 214 and the first rotating rod 207 are rotated, so that the first rotating rod 207 can be unfolded and closed. When the laser rangefinder body 130 needs to be held by hand, the first rotating rod 207 can be closed together. When the laser rangefinder body 130 needs to be placed on the ground, in order to improve the placement stability of the laser rangefinder body 130, the first rotating rod 214 can be opened. 07 is unfolded, and the first bevel gear 209 is driven to rotate by rotating the adjusting knob 208. The bevel gear meshing connection between the first bevel gear 209 and the second bevel gear 210 is utilized to make the adjusting threaded sleeve 212 move on the second adjusting threaded rod 211 while driving the second rotating rod 214 to rotate, thereby realizing the angle adjustment of the third rotating rod 217, which can be adjusted accordingly according to the unevenness of the wall or the ground, and is convenient for accurate distance measurement. The fixed cone 220 at the bottom of the supporting base plate 219 is used to realize the stable support of the third rotating rod 217, and the supporting spring 222 is used to realize the angle adjustment of the supporting base plate 219, thereby improving the supporting stability of the supporting base plate 219.
