The invention relates to the technical field of geological surveying and mapping equipment, in particular to an angular displacement resetting device and method of a geological surveying and mapping instrument. The working bin is horizontally arranged in the shell and located on one side of the gear ring. The take-up wheel is rotatably arranged in the working bin, and a traction rope is wound on the take-up wheel; the sliding block is slidably arranged in the working bin in the length direction of the working bin, the end, away from the take-up wheel, of the traction rope is fixedly connected with the sliding block, and a first gap exists between one side of the sliding block and the inner wall of the working bin; the first spring is arranged in the first gap; the limiting assembly is arranged on the upper portion of the working bin and can limit the sliding block sliding in the working bin. The unlocking assembly is arranged on one side of the limiting assembly; the transmission assembly is arranged between the gear ring and the take-up wheel, and the gear ring drives the take-up wheel to wind the traction rope through the transmission assembly, so that after surveying and mapping are finished, accurate resetting can be achieved, and subsequent surveying and mapping use is facilitated.

    本发明涉及地质测绘设备技术领域,具体是涉及一种地质测绘仪的角位移复位装置及方法,包括外壳、归位装置和齿环;工作仓水平的设置在外壳的内部,工作仓位于齿环的一侧;收线轮能转动的设置在工作仓内,收线轮上缠绕有牵引绳;滑动块沿工作仓的长度方向能滑动的设置在工作仓内,牵引绳远离收线轮的一端与滑动块固定连接,滑动块的一侧与工作仓内壁之间存有第一间隙;第一弹簧设置在第一间隙内;限位组件设置在工作仓的上部,限位组件能对在工作仓内滑动的滑动块进行限位;解锁组件设置在限位组件的一侧;传动组件设置在齿环和收线轮之间,齿环通过传动组件带动收线轮将牵引绳收卷,使得在测绘结束后,能实现精确复位,便于后续测绘使用。
