[0023] Working principle: the existing distance measuring device cannot provide accurate prompts when aiming during the process of measuring the distance of the golf ball, resulting in low aiming efficiency. By holding the distance measuring device, the eyepiece 12 is aimed at one eye of the operator. The eyepiece 12 is an LED display screen. The LED display screen displays a high-definition field picture, and the center is the aiming frame. When the aiming frame is aimed at the golf ball, the processor controls the prompt light 23 to light up and emit a prompt sound. At this time, the operator presses the laser trigger button 20, and the laser passes through the transmitting mirror 15 to emit laser. After being reflected by the golf ball, the laser is scattered in all directions. Part of the scattered light returns to the receiving mirror 14 and is received by the laser detector. The laser detector converts the optical signal into a corresponding electrical signal, records and processes the time from the laser emission to the return of the laser. The time elapsed and the propagation speed of the laser in the air can be used to determine the distance of the golf ball. The LED display screen will then display the measured distance, slope angle, power display, slope adjustment distance and other data values. This mechanism can provide accurate prompts after aiming the golf ball, which is beneficial to improving the aiming efficiency. The existing distance measuring device cannot protect the receiving mirror 14 and the transmitting mirror 15. After long-term use, the lenses are easily damaged, resulting in poor protection of the lenses. By installing a protective cover 16 on the periphery of the receiving mirror 14 and the transmitting mirror 15, during the use of the device, the protective cover 16 is pushed so that the protective cover 16 rotates along the rotating shaft until the protective cover 16 contacts the second positioning block 18, and the second positioning block 18 is a magnet and is in contact with the protective cover 1 6, the magnets at the corresponding positions on the protective cover 16 are attracted to each other, so that the protective cover 16 is stably placed. When the device is not in use, the protective cover 16 is rotated in the opposite direction until the protective cover 16 contacts the first positioning block 17. The first positioning block 17 is a magnet and is attracted to the magnets at the corresponding positions on the protective cover 16. At this time, the protective cover 16 covers the receiving mirror 14 and the transmitting mirror 15, so as to protect the receiving mirror 14 and the transmitting mirror 15, which is beneficial to improve the protection of the lenses. The existing distance measuring device is used in a hand-held manner. After use, the device needs to be placed and cannot be carried portable, resulting in poor portability. By pulling the strap 11 out of the reel 3, the strap 11 drives the rotating rod 4 to rotate during the pulling process, and the rotating rod 4 drives the spring 5 to rotate. The spring 5 is deformed, and the shoulder strap 11 is pulled out to a suitable length and then carried on the shoulder, and then the driving block 9 is pushed. The driving block 9 drives the positioning rod 8 to slide in the sliding groove 7, and the positioning rod 8 presses and fixes the shoulder strap 11. During the sliding of the positioning rod 8, the protrusion 10 on the positioning rod 8 gradually slides into the sliding groove 7, and the protrusion 10 is stuck in the sliding groove 7, thereby fixing the positioning rod 8 and making the device portable. When it is needed, the driving block 9 is pushed in the reverse direction, and the positioning rod 8 releases the shoulder strap 11, and then the spring 5 returns to its original state. During the restoration of the spring 5, the rotating rod 4 is pulled to reel in the shoulder strap 11, thereby achieving rapid reeling of the shoulder strap 11. This structure allows the ranging device to be portable and is conducive to improving the portability of the ranging device.
