The two threaded sections of the bidirectional screw 5 are screwed together with movable blocks 6, and one end of the bidirectional screw 5 extends to the outside of the mounting seat 2 and is fixed with a handle 8. The top ends of the two movable blocks 6 are fixedly connected to two clamps 7 respectively.

[0031] A rubber pad 15 is fixed to the inner side of the clamping plate 7. The elastic action of the positioning rod 11 can strengthen the clamping effect of the surveying and mapping instrument.

[0032] Three fixed arms 3, the three fixed arms 3 are connected to the bottom side of the base 1 in a circular array, and a sliding cavity 9 is opened inside the fixed arm 3, and a connecting arm 10 is slidably connected inside the sliding cavity 9, and the bottom end of the connecting arm 10 extends outside the sliding cavity 9 and is fixed with a positioning rod 11;

[0033] The bottom end of the positioning rod 11 is conical, and the conical design facilitates the positioning rod 11 to be better inserted into the ground.

[0034] A support seat 16 is fixed to the side wall of the bottom end of the fixed arm 3, and the bottom end of the support seat 16 is rotatably connected to a connecting shaft 17 through a bearing, a fixing handle 19 is fixed to one end of the connecting shaft 17, and a gear 18 is fixed to the other end of the connecting shaft 17.
