[0024] Specifically, as shown in Figure 1 and Figure 3 , when in use, by the action of the guide ring 2, the guide groove 14, and the limit groove 15, it is convenient to circularly expand a plurality of movable support rods 5 along the edge of the support base 1, so that the movable support rods 5 and the central rod 4 form a circular wrapping effect on the surveying instrument, so as to seal and prevent dust, and by using the limit groove 15, it is convenient to make the movable support rods 5 in a vertical state to ensure the stability of the entire wrapping structure;

[0025] Moreover, a guide groove 14 is opened inside the guide ring 2, and a limit groove 15 communicates with the top end of the guide groove 14. A plurality of movable balls 16 are slidably installed inside the guide groove 14, and movable support rods 5 are installed at the top ends of the movable balls 16;

[0026] There are two movable support rods 5, and each group of movable support rods 5 has three. Each group of movable support rods 5 is equally spaced. The two groups of movable support rods 5 are respectively located on both sides of the central rod 4, and the side walls of two of the movable support rods 5 are close to each other;

[0027] Specifically, as shown in Figure 1 and Figure 3 and Figure 4 , when in use, by the action of the bending rod 6, it is convenient to further support the top dust-proof cloth 10, so that it cooperates with the top dust-proof cloth 10 to form a shielding effect above the surveying instrument;

[0028] The top ends of the movable support rods 5 all penetrate to the outside of the limit groove 15. An L-shaped hinge block 3 is installed on the outer side of the bottom end of the support base 1, and a central rod 4 is hinged to the outer side of the L-shaped hinge block 3. Bending rods 6 are hinged to the top ends of the central rod 4 and the movable support rods 5, and a dust-proof component is bonded to the outer sides of the movable support rods 5 and the bending rods 6;

[0029] The dust-proof component includes a side dust-proof cloth 8, and a connecting strip 9 is installed at the top end of the side dust-proof cloth 8, and a top dust-proof cloth 10 is installed at the top end of the connecting strip 9. The side dust-proof cloth 8, the connecting strip 9 and the top dust-proof cloth 10 are woven and connected. The unfolded lengths of the side dust-proof cloth 8, the connecting strip 9 and the top dust-proof cloth 10 are adapted to the circumference of the support base 1. The inner sides of the side dust-proof cloth 8, the connecting strip 9 and the top dust-proof cloth 10 are respectively bonded to the outer walls of the central rod 4, the movable support rod 5 and the bent rod 6;

[0030] The central rod 4 is located on the central axis of the side dust-proof cloth 8. The connecting strip 9 is located at the hinge joint between the central rod 4, the movable support rod 5 and the bent rod 6. The width of the top dust-proof cloth 10 is greater than the length of the bent rod 6;

A right zipper 13 is connected to the other side of the side dust-proof cloth 8, the connecting strip 9 and the top dust-proof cloth 10. Through the cooperation of the left zipper 12 and the right zipper 13, the side dust-proof cloth 8, the connecting strip 9 and the top dust-proof cloth 10 form a closed loop with a closed end;

[0033] Locking ropes 11 are installed on both sides of the outer edge of the top end of the top dust-proof cloth 10. Through the locking ropes 11, it is convenient to surround and lock the top end of the top dust-proof cloth 10;

[0035] Specifically, as Figure 1 , Figure 2 shown, when in use, by the effects of the locking ropes 11 and the left zipper 12 and the right zipper 13, the connection and assembly of the entire protection component are further finalized at the end. And this assembly method realizes the foldability of the protection component, thereby avoiding blocking and hindering the use of the theodolite.

[0036] Working principle: When the utility model is in use, first install the whole surveying instrument at the center position on the top of the support base 1. When dust prevention and protection for the surveying instrument is needed, turn the central rod 4 upwards along the L-shaped hinge block 3, and at the same time turn multiple movable support rods 5 upwards synchronously along the turning groove 7, so that the central rod 4 and the movable support rods 5 are kept vertical, and then turn the bent rod 6 upwards by a certain angle, so that it drives the top dust-proof cloth 10 to block above the support base 1;

[0037] Secondly, pull the movable support rod 5 on the same side, so that the movable ball 16 slides along the guiding groove 14, and then the movable support rods 5 are unfolded from each other, so that the movable support rods 5 pull the side dust-proof cloth 8 to unfold, and in combination with the top dust-proof cloth 10 to form a wrapping effect on the surveying instrument. The side walls of the two movable support rods 5 are close to each other, so as to facilitate the docking of the left zipper 12 and the right zipper 13. By closing the left zipper 12 and the right zipper 13, the surrounding wrapping of the surveying instrument is ensured;

[0038] Finally, use the locking rope 11 to wind the opening formed at the top of the top dust-proof cloth 10, so as to realize the air outlet at the top, ensure that the surveying instrument is in a closed environment, and avoid dust from entering.
