Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of laser rangefinders, in particular to a handheld laser rangefinder. Background Art
[0002] A laser rangefinder is an instrument that uses a certain parameter of a modulated laser to accurately measure the distance to a target. A handheld laser rangefinder is a type of laser rangefinder that generally measures distances within 200 meters with an accuracy of approximately 2mm. It is currently the most widely used laser rangefinder. When using a handheld laser rangefinder, a mobile terminal with a camera is often mounted on the top of the rangefinder, allowing the user to view the distant laser point through the mobile terminal.
[0003] However, existing handheld laser rangefinders have a fixed-size clamping element on their top, making them difficult to clamp and secure mobile devices of varying sizes. Furthermore, when measuring non-horizontal targets, where there is an angular difference between the laser emitted horizontally from the measuring point and the target, the operator can only measure the target based on a subjective estimate of the angle, resulting in significant accuracy deviations. Therefore, a handheld laser rangefinder is urgently needed to address these issues. Utility Model Content
