It can be seen from the figure that the first assembly bolt 13 and the second assembly bolt 14 need to be connected obliquely downward on the side wall of the RTK bottom shell 10. When the prior art is installed, the worker holds the RTK bottom shell 10 and holds the screwdriver obliquely downward for connection, which is easy to cause the screw to slip. When the jig of the embodiment is used, the RTK bottom shell 10 is placed in the positioning groove 101, and then the bearing table 1 is rotated, so that the hole of the key support assembly 11 is aligned with the hole of the RTK bottom shell 10 to be installed and the hole is perpendicular to the table top. Therefore, when the first assembly bolt 13 is locked by the screwdriver, vertical feeding can be realized. After installation, the bearing table 1 is rotated in the opposite direction, the hole of the USB support assembly 12 is aligned with the hole of the RTK bottom shell 10 to be installed and the hole is perpendicular to the table top. Therefore, when the second assembly bolt 14 is locked by the screwdriver, vertical feeding can be realized.

[0044] In summary, the utility model provides an auxiliary assembly jig, which connects a rotatable positioning device on a support. During assembly, the workpiece is positioned and fixed on the positioning device, and then the positioning device is rotated to make the screw hole of the workpiece installation screw perpendicular to the workbench top or horizontal plane, so that the screwdriver can be operated vertically.
