Unless otherwise clearly specified and limited, the terms "setting", "installation", "connection", etc. should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0026] like Figure 1 and Figure 7 As shown, a construction project cost on-site surveying and mapping device includes a fixed plate 4, the top of the fixed plate 4 is rotatably connected to a total station 1, the bottom of the fixed plate 4 is fixedly connected to multiple sets of rotating seats 402, the rotating seats 402 are rotatably connected to legs 2, the bottom of the legs 2 is fixedly installed with supporting feet 3, the supporting feet 3 are inserted into the ground, and the supporting feet 3 can make the surveying and mapping device more stable on muddy ground, the fixed plate 4 includes a plate body 401, the bottom of the plate body 401 is fixedly connected to a rotating base 403, and the rotating base 40 The inner wall of the rotating slide bar 3 is rotatably connected with a rotating slide bar 5, the surface of the rotating slide bar 5 is slidably connected with a supporting slide seat 6, the bottom of the rotating slide bar 5 is fixedly connected with a rotating handle 7, the side of the supporting slide seat 6 is rotatably connected with a telescopic rod 1 8, the inner wall of the telescopic rod 1 8 is slidably connected with a telescopic rod 2 11, the surface of the telescopic rod 1 8 is fixedly connected with a spiral locking sleeve 9, the surface of the spiral locking sleeve 9 is threadedly connected with a tightening handle 10, the inner side of the upper part of the leg 2 is fixedly connected with a rotating seat 1 201, and the rotating seat 1 201 is rotatably connected to one end of the telescopic rod 2 11. After taking the surveying and mapping instrument to the location to be measured, turn the handle 7 to the left to adjust the contact position of the rotating slide bar 5 and the supporting slide seat 6, open the leg 2 to a certain angle, and the supporting slide seat 6 rises along the rotating slide bar 5. The three groups of legs 2 are opened to the same angle, and the handle 7 is turned to the right to fix the position of the supporting slide seat 6 on the rotating slide bar 5. The angle of the leg 2 is fixed. When the surveying and mapping instrument is set up on the inclined plane, loosen the tightening handle 10 corresponding to the leg 2 on the high side, and pull the telescopic rod 2 11 out of the telescopic rod 1 8, thereby further expanding the opening angle of this leg 2, so as to readjust the surveying and mapping instrument to a horizontal state, thereby ensuring the stability of the surveying and mapping instrument when it is set up on the inclined plane.

[0027] like Figure 2 As shown, the rotating slide bar 5 includes a slide bar 502, a rotating disk 501 is fixedly connected to the top of the slide bar 502, the rotating disk 501 is rotatably connected to the rotating base 403, and a rubber locking strip 503 is fixedly installed on the surface of the slide bar 502. The rotating slide bar 5 and the supporting slide seat 6 together form a locking mechanism.

[0028] like Figure 3 , Figure 4 and Figure 5As shown, the support slide 6 includes a support seat 601, and a swivel seat 3 602 is fixedly connected to the side of the support seat 601. The swivel seat 3 602 is rotatably connected to the telescopic rod 1 8. The support slide 6 moves up and down on the surface of the rotating slide bar 5, driving the legs 2 to open at the same time. A through hole 604 is opened in the center of the support seat 601, and a limit block 603 is fixedly connected to the through hole 604. The inner wall of the limit block 603 is slidably connected to the slide bar 502. The limit block 603 ensures that the support slide 6 slides smoothly on the surface of the slide bar 502. At the same time, the contact between the limit block 603 and the rubber locking strip 503 limits the rotation angle of the rotating slide bar 5 relative to the support slide 6, so that the rotating slide bar 5 only needs to rotate a smaller range in the support slide 6 to be adjusted to a locked state or a sliding state; the locking and sliding states of the support slide 6 on the rotating slide bar 5 are changed The rubber locking strip 503 is connected to the locking block 607 by the rubber locking strip 503, and the friction between the locking block 607 and the rubber locking strip 503 is used to lock the support slide 6 on the rotating slide 5. The rubber locking strip 503 is separated from the locking block 607 by rotating the rotating slide 5 in the opposite direction, and the friction between the locking block 607 and the rubber locking strip 503 disappears, so that the support slide 6 resumes sliding on the surface of the rotating slide 5. The support seat 601 is fixedly connected with the installation box 605 inside, and the installation box 605 is fixedly connected with the installation cylinder 606 at the bottom, and the side wall of the installation box 605 is slidably connected with the locking block 607. The bottom of the locking block 607 is fixedly connected with the guide rod 609, and the inner wall of the installation cylinder 606 is movably contacted with a spring 608, and the inner side of the spring 608 is movably contacted with the guide rod 609.

[0029] like Figure 6As shown, the locking block 607 includes a sliding surface 607A, a transition surface 607B is fixedly provided on one side of the sliding surface 607A, a locking surface 607C is fixedly provided on the other side of the transition surface 607B, and a horizontal convex strip is fixedly provided on the locking surface 607C, and the horizontal convex strip cooperates with the rubber locking strip 503. By rotating the rotary handle 7, the rubber locking strip 503 gradually contacts the locking surface 607C, the spring 608 is compressed, the locking block 607 is retracted into the installation box 605, and the extrusion force between the locking surface 607C and the rubber locking strip 503 increases. Due to the existence of the horizontal convex strip, the rubber locking strip 503 and the locking surface 607C are allowed to rotate horizontally, allowing the rubber locking strip 503 to quickly cut into and fit the locking surface 607C, but preventing the rubber locking strip 503 from moving vertically up and down relative to the locking surface 607C. At this time, the locking block 607 and the rubber locking strip 503 are in a state of being locked. The friction between them is extremely large, the support slide 6 cannot move on the rotating slide bar 5, the opening angle of the leg 2 is fixed, and the stability of the surveying and mapping instrument is guaranteed. The rotating handle 7 is rotated in the opposite direction, so that the rubber lock strip 503 contacts the locking surface 607C, the transition surface 607B, and finally the sliding surface 607A in turn. At this time, the spring 608 is not compressed and the surface of the sliding surface 607A is smooth. The friction between the sliding surface 607A and the rubber lock strip 503 is extremely low, the support slide 6 can slide freely on the rotating slide bar 5, and the angle of the leg 2 can continue to be modified.

[0030] like Figure 8 As shown, the spiral lock sleeve 9 includes a spiral cylinder 901, the inner wall of the spiral cylinder 901 is fixedly connected to the surface of the telescopic rod 18, the top of the spiral cylinder 901 is fixedly connected to a tensioning cylinder 902, and the inner wall of the tensioning cylinder 902 is in active contact with the surface of the telescopic rod 211. The tightening handle 10 includes a spiral sleeve 1001, the spiral sleeve 1001 is threadedly connected to the spiral cylinder 901, the top of the spiral sleeve 1001 is fixedly connected to a compression sleeve 1002, the inner wall of the compression sleeve 1002 is in active contact with the surface of the tensioning cylinder 902, and the surface of the tightening handle 10 is fixedly provided with anti-slip grooves 1003. The telescopic rod 1 8, the spiral locking sleeve 9, the tightening handle 10 and the telescopic rod 2 11 together constitute a telescopic mechanism. By rotating the tightening handle 10, the clamping sleeve 1002 is gradually separated from the tensioning tube 902, the opening of the tensioning tube 902 is gradually expanded, and the friction between the tensioning tube 902 and the telescopic rod 2 11 is gradually reduced. The length of the telescopic rod 2 11 extending from the telescopic rod 1 8 is adjusted, and the opening angle of the leg 2 in this direction is adjusted. After adjusting to a suitable opening angle, the tightening handle 10 is rotated in the opposite direction to make the clamping sleeve 1002 gradually squeeze the tensioning tube 902, the opening diameter of the tensioning tube 902 is gradually reduced, and the friction between the tensioning tube 902 and the telescopic rod 2 11 is gradually increased. The length of the telescopic rod 2 11 extending from the telescopic rod 1 8 is fixed, and the opening angle of the leg 2 in this direction is fixed.

[0031] The utility model realizes locking and movement of the support slide 6 on the rotating slide rod 5 by providing a rubber locking strip 503 and a locking block 607; and realizes adjustment of the opening angle of each individual support leg 2 by providing a spiral locking sleeve 9 and a tightening handle 10, so that the surveying and mapping instrument is more stable when set up on an inclined ground.
