Description

Technical Field

[0001] The utility model relates to the technical field of laser rangefinders, in particular to a laser rangefinder fixer. Background Art

[0002] Laser rangefinder is an instrument that uses a certain parameter of modulated laser to measure the distance to the target. The measurement range of laser rangefinder is 3.5 to 5000 meters. According to the distance measurement method, it is divided into phase method rangefinder and pulse method rangefinder. Pulse laser rangefinder emits a beam or a series of short pulse laser beams to the target when working. The laser beam reflected by the target is received by the photoelectric element. The timer measures the time from the emission to the reception of the laser beam and calculates the distance from the observer to the target. Phase method laser rangefinder detects the distance by detecting the phase difference between the emitted light and the reflected light when propagating in space. Laser rangefinder is light in weight, small in size, simple to operate, fast and accurate.

[0003] For example, the authorization announcement number "CN208444003U" is named a laser rangefinder fixing device. Although the cooperation between pulling the second connecting plate to the left to make the pull rod squeeze the compression spring inside the inner opening of the first connecting plate and rotating the screw to squeeze the insertion rod inserted into the card block effectively fixes the rangefinder stably on the first clamping plate and the second clamping plate, increases the stability of the rangefinder when using it, and meets the needs of users, but the existing laser rangefinder fixing device uses a structure of clamping the laser rangefinder on both sides to achieve a fixing effect, but one Generally, the use of a laser rangefinder requires that one end of the emitting laser be aimed at a position with a certain measuring distance of the object to be detected, and then the distance is measured using the laser reflection time. However, the current laser rangefinder fixing device can only clamp and fix the laser rangefinder, and then the operator can hold it in the hand for distance measurement. Therefore, it is inconvenient to firmly and stably set up the laser rangefinder fixing device on the ground for fixed use, because the human hand will tremble or deflect, and the laser rangefinder cannot be accurately fixed and placed intact. Therefore, the laser rangefinder fixing device is easy to affect the distance measurement accuracy of the laser rangefinder.

[0004] At the same time, the existing laser rangefinder fixing device can only measure the distance of a certain position by holding the handle by hand, but when the distance to be measured is at a higher place, the operator needs to raise his arm, and then align the laser rangefinder with the high position and place it horizontally to accurately measure the distance, which causes a large burden on the operator's workload. Therefore, the existing laser rangefinder fixing device lacks a structure that can hang the laser rangefinder and fix it at a high place for measurement, which reduces the scope of application of the laser rangefinder fixing device.
