[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The embodiments of this utility model will be described below based on its overall structure.

[0022] Please see Figure 1 - Figure 5 A support device for portable geographic surveying equipment includes a platform 1, a mounting base 2 installed on the upper end of the platform 1, and a threaded rod 3 installed on the outer end of the mounting base 2. The mounting base 2 is threadedly connected to the platform 1 via the threaded rod 3, and the mounting base 2 fits tightly against the platform 1. The mounting base 2 installed in the device ensures flatness and provides a certain degree of balance assistance for the geographic surveying equipment. A sleeve 4 is installed at the lower end of the platform 1, and a rotating shaft 5 is installed at the bottom of the sleeve 4. A pull-retracting rope 7 is installed inside the sleeve 4, and a pull ring 6 is installed at one end of the pull-retracting rope 7. The pull-retracting rope 7 forms a rotating structure with the sleeve 4 via the rotating shaft 5, and the pull-retracting rope 7 is engaged with the pull ring 6. The pull-retracting rope 7 installed in the device can be pulled, and after pulling, it can wind around four support frames 9. After winding, the entire device can be carried by installing the pull ring 6. A movable shaft 8 is installed on the outer end of the platform 1, and a support frame 9 is installed at one end of the movable shaft 8.
