Abstract
A laser distance finder including a laser generating device, a collimating lens positioned in an emitting end direction of the laser generating device, a receiving lens for receiving a reflected measuring beam from an object to be measured and focusing it into an image, an optoelectronic detector disposed in the distance finder, a reflective member rotatably mounted on an optical path of the collimating measuring beam via a rotating shaft and being capable of rotating to a first position and a second position around the rotating shaft, which is connected to an output shaft of a motor. The laser distance finder further includes a spring, and the reflective member that rotates to a desired position rapidly and exactly by utilizing various deformation status of the spring, thus saving power.

A laser distance finder, comprising:
- a laser generating device;
- a collimating lens positioned in an emitting end direction of the laser generating device for converting a laser beam generated from the laser generating device into a collimating measuring beam;
- a receiving lens for receiving a reflected measuring beam from an object to be measured and focusing it into an image;
- an optoelectronic detector for receiving the image from the reflected measuring beam;
- a reflective member rotatably mounted on an optical path of the collimating measuring beam via a rotating shaft, the reflective being capable of rotating to a first position and a second position around the rotating shaft, the rotating shaft being connected to an output shaft of a motor;
- a spring having a first end and a second end, the first end connected to the reflective member and the second one end fixedly mounted in the distance finder;
- and, wherein the spring has a maximum deformation position between the first position and the second position.
