Description

Technical Field

[0001] The utility model relates to the technical field of project cost, in particular to a laser rangefinder for project cost. Background Technique

[0002] A laser rangefinder is an instrument that accurately measures the distance to a target using a laser. When the laser rangefinder works, it emits a very thin laser beam towards the target. The laser beam reflected by the target is received by a photoelectric element, and a timer measures the time from the emission to the reception of the laser beam to calculate the distance from the observer to the target.

[0003] As disclosed in a positioning device for a laser rangefinder for project cost in Chinese Patent CN 219799765 U, the utility model discloses a positioning device for a laser rangefinder for project cost, which relates to the technical field of project cost and includes a base device. One side of the base device is movably connected with a fixing device, and one side of the base device is rotatably connected with a lifting device. One side of the lifting device is fixedly connected with a placing device. The fixing device includes a pedal. One side of the pedal is fixedly connected with a fixing insertion rod, and one side of the pedal is movably connected with a fixing block. Through the cooperation of the pedal and the fixing insertion rod, the problem that the positioning device is not firmly fixed on a softer bottom is solved, and the purpose of improving the stability of the laser rangefinder is achieved. Through the cooperation of the base and the rubber ring, the problem of poor fixity when the bottom surface is relatively smooth is solved, thereby achieving the purpose of improving the practicability of the positioning device and reducing the measurement error of the laser rangefinder at the same time.

[0004] In the above patent background technology, it is proposed that the existing device cannot fix the positioning device, resulting in inaccurate ranging data. Although the above patent can use devices such as pedals to fix the positioning device to improve the accuracy of ranging data, when fixing the rangefinder, only devices such as springs are used to fix and clamp the rangefinder. Although this method is effective, the spring has a certain elasticity. If the positioning device is subjected to a shock force, it is very likely that the spring will rebound, causing the rangefinder to fall off the positioning device, which may affect the ranging effect of the rangefinder. Seriously, it will also damage the rangefinder and affect the use of the rangefinder by personnel. Content of the Utility Model
