[0020] The shading plate 202 is provided to block the influence of direct light from both sides on observation.

[0021] like Figure 2 , Figure 3 and Figure 4 As shown, the adjustment component 3 includes a rotating shaft 301 arranged inside the mounting frame 2, a storage cavity is opened inside the mounting frame 2, the rotating shaft 301 is located inside the storage cavity, and both ends of the rotating shaft 301 pass through the storage cavity and are rotatably connected to the inner wall of the mounting frame 2, a blackout curtain 303 located inside the storage cavity is wound on the surface of the rotating shaft 301, a notch connected to the storage cavity is opened on the surface of the mounting frame 2, one end of the blackout curtain 303 passes through the notch and is fixedly connected to a baffle 305, the top of the baffle 305 blocks the notch, and the bottom of the baffle 305 is fixedly connected to a pull ring, one end surface of the rotating shaft 301 is fixedly connected to a spring 304, and the other end of the spring 304 is fixedly connected to the inner wall of the mounting frame 2;

[0022] By pulling the pull ring, the baffle 305 can be driven to pull the blackout curtain 303, which can drive the rotating shaft 301 to rotate and unwind the blackout curtain 303, so that the shading effect can be adjusted according to the actual situation, reducing the influence of outdoor light on the data of the total station body 4 when recording. The spring 304 is set to tighten the spring 304 during the process of the rotating shaft 301 rotating and unwinding the blackout curtain 303, so that after the pull ring is loosened, the rotating shaft 301 can be reset under the action of the spring 304, thereby achieving the effect of automatically winding up the blackout curtain 303, without manual winding, and easy operation.

[0023] like Figure 2 , Figure 3and Figure 4 As shown, a rotating block 306 is fixedly connected to the other end surface of the rotating shaft 301, and the rotating block 306 is slidably connected to the inner wall of the mounting frame 2. The surface of the rotating block 306 is provided with evenly distributed card grooves 307, and the inner wall of one side of the card groove 307 is set in an inclined surface. A mounting cavity 302 is opened inside the mounting frame 2, and a card plate 308 is slidably connected to the inner wall of the mounting cavity 302. The lower end of the card plate 308 passes through the mounting cavity 302 and extends to the inside of the adjacent card groove 307. The bottom of the card plate 308 is set in an arc surface. Two connecting rods 309 are fixedly connected to the top of the card plate 308.

At this time, the rotating shaft 301 can be driven to rotate and reset under the action of the spring 304, and the blackout curtain 303 can be rolled up to the inside of the placement cavity at the same time, so as to achieve the effect of automatically rolling up the blackout curtain 303, which is easy to operate.

[0026] When the utility model is in use, the device is placed at a position to be measured through the support frame 1, and the shading plates 202 on both sides of the top plate 201 can block the influence of direct light on the observation on both sides, and the baffle 305 can be driven to pull the shading curtain 303 by pulling the pull ring, which can drive the rotating shaft 301 to rotate and unwind the shading curtain 303, so that the shading effect can be adjusted according to the actual situation, reducing the influence of outdoor light on the data of the total station body 4. The mutual cooperation of the card slot 307, the card plate 308, the spring 310 and the connecting rod 309 The position of the blackout curtain 303 can be automatically locked after the blackout curtain 303 is adjusted into place, so as to facilitate use. When the blackout curtain 303 needs to be rolled up, the connecting rod 309 can be driven to move synchronously by pulling the pull plate 311, thereby driving the card plate 308 to separate from the card slot 307, so as to achieve the effect of releasing the limit of the rotating block 306. At this time, the rotating shaft 301 can be driven to rotate and reset under the action of the spring 304, and the blackout curtain 303 can be rolled up to the inside of the placement cavity at the same time, so as to achieve the effect of automatically rolling up the blackout curtain 303, and the operation is easy.
