[0032] The connecting component includes a limiting tube 5 fixedly set on the rotating ball 301, an electric telescopic rod 402 fixedly connected to the measuring instrument 4, the electric telescopic rod 402 is slidably set in the limiting tube 5, and a limiting block 403 matching the limiting tube 5 is fixedly connected to the electric telescopic rod 402.

[0033] In forestry planning and design, when it is necessary to measure the planned land, the carrying handle 204 carries the protective box 2 to the measuring point, and the protective box 2 protects the measuring instrument 4, thereby effectively preventing the measuring instrument 4 from being damaged during transportation, and effectively improving the portability of the measuring instrument 4 in transportation.

[0034] When measuring, the support rod 1 is supported by the support leg 101, and then the protection box 2 is installed on the positioning frame 202 through the insertion rod 201 and the locking nut 203, and the positioning frame 202 is connected to the support rod 1, and the magnetic doors 205 on both sides are opened. At this time, the measuring instrument 4 drives the rotating ball 301 to rotate under the action of gravity, so that the measuring instrument 4 is always in a horizontal state, thereby avoiding the need to adjust the support leg 101 to make the measuring instrument 4 horizontal, thereby effectively improving its measurement efficiency and ensuring its measurement accuracy.

[0035] Example 2: Reference Figure 1-Figure 7 A portable measuring device for forestry planning and design is basically the same as Example 1. Further, a connecting plate 501 is fixedly connected to the limiting tube 5, and a second spring 502 is symmetrically fixedly connected between the connecting plate 501 and the measuring instrument 4.

[0036] The vertical position of the measuring instrument 4 is adjusted by extending and retracting the electric telescopic rod 402 , thereby facilitating fine adjustment of the vertical position of the measuring instrument 4 .

[0037] Example 3: Reference Figure 1-Figure 7 , a portable measuring device for forestry planning and design, which is basically the same as Example 1, and further, a cavity 302 is arranged in the rotating ball 301, a fixed shaft 303 is arranged in the cavity 302, a plurality of limit rods 304 are fixedly connected to the fixed shaft 303, a squeezing rod 306 is slidably arranged on the limit rod 304, a friction pad 308 is fixedly connected to the end of the squeezing rod 306, a first limit plate 305 is fixedly connected to the limit rod 304, a first spring 307 is fixedly connected between the first limit plate 305 and the squeezing rod 306, one end of the squeezing rod 306 is slidably arranged on the rotating ball 301, and a driving component for driving the squeezing rod 306 to slide out is arranged on the rotating ball 301.

At this time, under the action of water pressure, the squeezing rod 306 is driven to slide in the direction of the ball groove 3, and the squeezing rod 306 drives the friction pad 308 to fit with the ball groove 3, thereby effectively fixing the rotating ball 301, and then effectively preventing the measuring instrument 4 from shaking during the measurement process and affecting its measurement results.

[0041] When the measuring instrument 4 is in the carrying protective box 2, it slides in the protective box 2 and squeezes the second spring 502, so that external air enters the sleeve 503 through the air inlet 504. When the measuring instrument 4 is reset, the gas in the sleeve 503 enters the jet square tube 507 through the air inlet pipe 506 and the connecting pipe 509 in turn, and is finally ejected through the jet port 508 to blow the dust on the lens 401, thereby effectively cleaning the dust on the lens 401.
