[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] As Figures 1 to 8 shown, the present invention provides a surveying device for territorial space planning, including a base 1, a positioning rod 2 fixedly connected to the bottom of the base 1, and further including:

[0034] A support assembly 3, the support assembly 3 is arranged in a circular distribution at the bottom of the base 1;

[0035] An adjustment assembly 4, the adjustment assembly 4 is arranged in the middle of the support assembly 3;

[0036] Among them, the support assembly 3 includes a second sliding block 307 slidably connected to the base 1 and a sliding sleeve 305 slidably connected to the positioning rod 2. The bottom of the second sliding block 307 is rotatably connected to a first support rod 301. The lower side of the first support rod 301 is slidably connected to a second support rod 302. The bottom of the first support rod 301 is rotatably connected to a third support rod 303;

[0037] The adjustment assembly 4 includes a fixed sleeve 401 slidably connected to the first support rod 301 and a straight tooth groove 409 opened at the top of the second support rod 302. A one-way tooth plate 402 is slidably connected inside the fixed sleeve 401. An adjustment gear 405 and a straight tooth plate 406 are rotatably connected to one side of the fixed sleeve 401 away from the one-way tooth plate 402.

[0038] Adopt the above scheme: By pushing down the fixed sleeve 401, the second support rod 302 is driven by the fixed sleeve 401 to move downward, so that the one-way tooth plate 402 is engaged with the one-way teeth 306. Then, the first support rod 301 is unfolded and the second support rod 302 is used to pierce the ground. Then, the base 1 can be leveled. The limit flap 408 is flipped to the vertical state to release the fixation of the corresponding second support rod 302. Then, the adjustment gear 405 is rotated to finely adjust the distance of the first support rod 301. Finally, the limit flap 408 is reset to complete the placement of the base 1.

[0039] As Figure 2 , Figure 3 and Figure 7 shown, the second support rod 302 is located outside the first support rod 301. A straight groove is provided in the middle of the first support rod 301 to limit the fixed sleeve 401. One end of the third support rod 303 close to the sliding sleeve 305 is rotatably connected with a first sliding block 304, and the first sliding block 304 is slidably connected with the sliding sleeve 305.

[0040] Adopt the above scheme: By setting the support assembly 3, the base 1 is supported by the combination of the first support rod 301 and the second support rod 302. At the same time, the first support rod 301 and the second support rod 302 that can be adjusted movably are convenient for storage. The third support rod 303 and the first sliding block 304 provided inside the first support rod 301 make the first support rod 301 stable after being unfolded. At the same time, always centered on the base 1, by setting that the first sliding block 304 and the sliding sleeve 305 can be rotatably connected, it is convenient for the first support rod 301 to close together when being stored.

[0041] As Figures 4 to 6 shown, the fixed sleeve 401 is movably connected with the second support rod 302. The one-way tooth plate 402 and the one-way teeth 306 are engaged with each other. A pair of springs 403 are fixedly connected to the side of the one-way tooth plate 402 away from the one-way teeth 306, and one end of the springs 403 is fixedly connected to the fixed sleeve 401.

[0042] Adopt the above scheme: By setting the fixed sleeve 401, the fixed sleeve 401 is slidably connected with the first support rod 301 through the straight groove on the side of the first support rod 301, so that the fixed sleeve 401 can limit the second support rod 302 to keep the second support rod 302 stable. The setting of the one-way tooth plate 402 and the straight tooth plate 406 can conveniently adjust the second support rod 302 over a large distance. The setting of the springs 403 can make the one-way tooth plate 402 keep in contact with the one-way teeth 306. At the same time, the tooth directions of the one-way tooth plate 402 and the one-way teeth 306 are opposite, so that when the one-way tooth plate 402 and the one-way teeth 306 are engaged, the fixed sleeve 401 can only slide unidirectionally along the first support rod 301.

[0043] As Figures 4 to 6As shown, a locking rod 404 is slidably connected inside the fixing sleeve 401, L-shaped limiting grooves are opened on both sides of the fixing sleeve 401, the locking rod 404 is located inside the limiting grooves, a vertical groove is opened in the middle of the one-way tooth plate 402, and the locking rod 404 is slidably connected to the vertical groove.

[0044] The above scheme is adopted: the setting of the locking rod 404 can facilitate the disconnection between the one-way tooth plate 402 and the one-way tooth 306, so that the fixing sleeve 401 can slide freely along the support rod 301, and the limiting groove opened on the outer side of the fixing sleeve 401 allows the locking rod 404 to slide to the bending position. Under the push of the spring 403, the locking rod 404 is squeezed by the one-way tooth plate 402, so that the locking rod 404 is fixed, and the one-way tooth plate 402 is limited by the locking rod 404, so that the one-way tooth plate 402 is released from the one-way tooth 306, and the straight groove opened in the middle of the one-way tooth plate 402 allows the locking rod 404 to move up and down.

[0045] like Figures 4 to 6 As shown, the adjustment gear 405 and the spur plate 406 are distributed on both sides of the support rod 302, the adjustment gear 405 is meshed with the spur groove 409, one end of the adjustment gear 405 penetrates the fixed sleeve 401 and is installed with a knob, one side of the spur plate 406 is clamped with the spur groove 409, and at the same time, a pair of tension springs 407 are fixedly connected to the side away from the spur groove 409;

[0046] An arc groove is provided in the middle of the straight tooth plate 406, and a limit flap 408 is abutted inside the arc groove. The limit flap 408 is hinged to the fixed sleeve 401, and one end of the limit flap 408 penetrates the fixed sleeve 401 and extends to the outside of the fixed sleeve 401. A limit protrusion is provided at the bottom of the limit flap 408 to abut against the limit flap 408, so that the limit flap 408 can only rotate within 90 degrees to a horizontal or vertical state.

[0047] The above scheme is adopted: by setting an adjustment gear 405 and a spur plate 406, the adjustment gear 405 and the spur plate 406 are connected with the spur tooth groove 409, so that the support rod 2 302 can be fixed inside the fixed sleeve 401, and the setting of the adjustment gear 405 can facilitate the adjustment of the support rod 2 302 for a small distance, and by setting the spur plate 406, the spur plate 406 is squeezed by the limiting flap 408 so that it is clamped inside the spur tooth groove 409, so as to fix the support rod 2 302, and the setting of the tension spring 1 407 is used to pull the spur plate 406 and the spur tooth groove 409 to disconnect when the limiting flap 408 does not interfere with the spur plate 406, so that the adjustment gear 405 can drive the support rod 2 302 to slide along the support rod 1 301.

[0048] like Figure 2 and Figure 8As shown, a locking assembly 5 is provided inside the base 1; the locking assembly 5 includes a pair of card blocks 501 and a sliding extrusion plate 503, the pair of card blocks 501 are both rotatably connected inside the base 1, a spring 502 is fixedly connected to one side of the card block 501, the sliding extrusion plate 503 is slidably connected to the base 1, and one end of the card block 501 located inside the base 1 is sleeved with a tension spring 2 504; the card blocks 501 are distributed on both sides of the sliding extrusion plate 503 in a mirror-image manner, the card blocks 501 are in conflict with the sliding extrusion plate 503, and a pair of conflicting plates are provided in the middle of the sliding extrusion plate 503, and the sliding extrusion plate 503 can be squeezed by the conflicting plates to squeeze the card block 501 to make it flip over.

[0049] The above scheme is adopted: by setting the card block 501, when the card block 501 is engaged with the sliding block 307, the support rod 1 301 can be triangularly distributed on the lower side of the base 1, and a pair of support rods 1 301 are fixed. The sliding extrusion plate 503 set inside the base 1 can squeeze the card block 501 to flip it, so that the card block 501 releases the fixation of the sliding block 2 307, so that the sliding block 2 307 can slide along the base 1 until the support rod 1 301 conflicts with each other, so that the support rod 1 301 can be gathered on one side, and at this time, the support rod 1 301 can be tied and fixed by an external fixing belt, and then it can be conveniently carried by hand through the positioning rod 2.

[0050] like Figure 2 , Figure 3 and Figure 8 As shown, the sliding block 2 307 is provided with two mirror-imaged sliding blocks 307 on the lower side of the base 1, and the support rod 1 301 located in the middle of the pair of sliding blocks 307 is directly connected to the base 1 for rotation, and a buckle is provided on the side of the pair of sliding blocks 307 facing the clamping block 501, and a surveying instrument body 6 is installed on the top of the base 1. After the clamping block 501 is released from the clamping connection with the sliding block 2 307, the sliding block 2 307 can drive the support rod 1 301 to move along the base 1 until it conflicts with the fixed support rod 1 301, so that the support rod 1 301 moves to the same side of the base 1.

[0051] The above scheme is adopted: by setting the sliding block 2 307, the support rod 1 301 can be movably adjusted, and the support rod 1 301 can be conveniently unfolded and folded by sliding the sliding block 2 307, which can be convenient for fixing and use. A support rod 1 301 is directly connected to the base 1 for rotation, and the position of the rotation merging can be controlled to prevent the sliding block 2 307 from sliding randomly at the bottom of the base 1.

[0052] Working principle and usage process of the present invention: When in use, untie the fixing strap outside the first support rod 301, then move the first support rod 301 to both sides to engage the second sliding block 307 with the clamping block 501, so that the first support rod 301 is unfolded. Then, first push the fixing sleeve 401 downward, and drive the second support rod 302 to move downward by the fixing sleeve 401, so that the one-way tooth plate 402 is engaged with the one-way tooth 306, making the first support rod 301 and the second support rod 302 combined into a suitable length. Then, align the positioning rod 2 with the surveying and mapping point position, then unfold the first support rod 301 and use the second support rod 302 to pierce into the ground. After that, the base 1 can be leveled. Flip the limiting flap 408 to the vertical state to release the fixation of the corresponding second support rod 302. Then, rotate the adjustment gear 405 to finely adjust the distance of the first support rod 301. Finally, reset the limiting flap 408 to complete the placement of the base 1;

[0053] When storing, first move the clamping rod 404 to drive the one-way tooth plate 402 to disengage from the one-way tooth 306, then the second support rod 302 can be retracted. After that, reset the clamping rod 404, and then pull the sliding extrusion plate 503 from the side to make the sliding extrusion plate 503 squeeze the clamping block 501 to flip, so that the clamping block 501 disengages from the second sliding block 307. Then, fold the first support rod 301 and fix it with an external fixing strap. Then, the entire bracket can be carried by hand holding the positioning rod 2.
