Remote control multi-angle positioning device

The invention discloses a remote control multi-angle positioning device comprising a support body, a horizontal rod, a rotating device, a vertical rod, a semicircular frame, a hand wheel and a transmission shaft, wherein, the support body is provided with a horizontal hollow pipe; the horizontal rod is arranged in the horizontal hollow pipe in an insertion manner; the rotating device is fixed on one end of the horizontal rod, and comprises a worm gear; one end of the vertical rod is connected with the support shaft of the worm wheel; the semicircular frame is fixed on the other end of the vertical rod, and is provided with a probe slot; the hand wheel is arranged on the other end of the horizontal rod in a rotatable manner; one end of the transmission shaft is connected with the hand wheel; and the other end of the transmission shaft is connected with the worm. The device of the invention can accurately adjust the positioning of the probe in X, Y, Z three-dimensional space and utilizes the selection of the lengths of the rod bodies (the horizontal rod and the vertical rod) in horizontal and vertical directions to adjust the distance of the probe and a detected object, thus greatly satisfying the requirements of multi-angle accurate measurement.
