Abstract

A manual laser-cursor image location device used in cameras pertains to cursor image location devices of optical instruments. The technical problem to be solved is to provide a manual laser-cursor image location device used in cameras. The manual laser-cursor image location device of the invention comprises a joint base, a step-hole, a camera coupling screw, a bulb, a bulb clamping ring, a laser-cursor balopticon, etc. The step-hole is positioned in the position which is slightly left-skewed in the middle of the joint base; a pit of the bulb and a thread hole of the bulb clamping ring are positioned at the right end of the joint base; a connection screw hole of a tripod is positioned at the center of the bottom of the camera coupling screw; the camera coupling screw runs through the step-hole on the joint base and is then connected with the step-hole by thread; the bulb runs through the thread hole of the bulb clamping ring and extends in the pit of the bulb and the connection between the bulb clamping ring and the thread hole of the bulb clamping ring is threaded connection; between the bulb and the pit of the bulb as well as the bulb clamping ring, rotary and sliding damping contact matching is adopted; the bulb is connected with a connection screw hole of the bulb on the laser-cursor balopticon by a bulb screw; the laser-cursor balopticon rotates internally and slides for damping matching through the pit of the bulb on the joint base.

Description

technical field [0001] The invention belongs to the technical field of optical instruments and relates to a manual laser cursor image positioning device for cameras. Background technique [0002] With the development of the national economy, the progress of society and the improvement of people's living standards, more and more people go out to travel, and taking pictures is the hobby of most tourists. way to take pictures. This requires choosing a location for taking pictures, and only when the location is selected accurately can an ideal photo be taken. If the position is not found correctly, there will be virtual phenomena or the matching between the characters and the background will not be coordinated. [0003] After checking the information, no relevant information was found. Contents of the invention [0004] In order to solve the problem of finding the correct photo position in the Selfie and take an ideal photo, a Selfie station device matching the camera is de...
