After the installation is completed, the stylus 200 is supported at the stylus mounting location 113.

According to the utility model discloses a base 100 for wand can extend wand 200's use scene for wand 200 can also be used for drawing this scanning, and wand 200 can conveniently be dismantled and install.

In some embodiments, the stylus mounting location 113 includes a plane that is disposed at an incline, as shown in fig. 7-9. The flat surface may be attached to the back surface of the wand 200, the back surface of the wand 200 being the side opposite the display screen 240 of the wand 200. Of course, the stylus mounting portion 113 may further include a protrusion, and after the stylus 200 is mounted on the stylus mounting portion 113, the lower end (the tip end) of the stylus 200 may abut against the protrusion to prevent the stylus 200 from falling.
