Description

Technical Field

[0001] The utility model relates to an instrument for measuring distance and slope, in particular to a portable handheld solar laser distance meter. Background Art

[0002] A laser rangefinder is an instrument that uses laser to measure distance. When working, it emits laser to the target. The rangefinder's photoelectric element receives the laser reflected from the target. The timer records the time from emission to reflection and reception, thereby calculating the distance between the rangefinder and the target, and further calculating the speed of the moving target. With the help of the built-in sensor, the slope angle between the rangefinder and the target can also be further calculated.

[0003] At present, laser rangefinders are widely used in outdoor places such as golf courses and hunting. Existing laser rangefinders are generally powered by batteries, and the batteries need to be replaced or charged after a period of use, which is not very convenient to use outdoors. In golf practice, by turning on or off the slope measurement, you can better guide the swing strength and facilitate training. However, when turning on or off the slope measurement of the existing laser rangefinder, you need to move and put down the rangefinder, and then turn on or off the slope switch, which will affect the continuity and consistency of the measurement and is inconvenient to use.
