Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are part of the present invention Examples, not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Please refer to FIG. 1 to FIG. 2 , this embodiment discloses a portable three-dimensional positioning device, which includes a base 1 , and a magnet is provided at the bottom of the base 1 . The base 1 is provided with a vertical pole 3 and a benchmark pole 4 arranged left and right, and the vertical pole 3 and the benchmark pole 4 both extend upwards in the vertical direction. The locking between the poles 3, the first digital display cursor 6 is installed on the sliding sleeve on the benchmark pole 4, and the first digital display cursor 6 is installed on the support base 5, and the support base 5 is also provided with a vertical mounting column 7, vertically A digital display protractor 8 is rotated on the mounting column 7, and the installation hole of the digital display protractor 8 is set on the vertical mounting column 7. A horizontally extending measuring ruler 9 is installed on the digital display protractor 8, and the measuring ruler 9 slides and is fitted with a second Two digital display cursors 10 . The bottom of the second digital display cursor 10 is provided with a needle 11 , and the bottom end surface of the needle 11 is flush with the bottom surface of the first digital display cursor 6 .

The first digital display cursor 6 is connected on the support seat 5 by the connection plate 12, the main body of the connection plate 12 is L-shaped, the vertical section of the connection plate 12 is fixedly connected with the support seat 5 by screws, the horizontal section right end of the connection plate 12 The front and rear sides are respectively provided with connecting pieces 13, and the two connecting pieces 13 respectively wrap the front and rear sides of the first digital display cursor 6 and extend beyond the right end of the first digital display cursor 6, and the two connecting pieces 13 extend out of the first digital display cursor 6.
