When in use, the bracket and the surveying device 3 are carried to the location where surveying is required, the bracket is supported on the ground, and then the surveying device 3 is mounted on the bracket, and surveying can be performed. In order to ensure that the bracket is more convenient to operate and more accurately adjusted, the bracket in this embodiment includes a mounting plate 1 for mounting the surveying device 3, at least three legs rotatably connected to the mounting plate 1, and at least three legs are evenly arranged around the circular mounting plate 1 to ensure stable support. In this embodiment, three legs are arranged around the circular mounting plate 1. In specific applications, four legs or more legs can also be evenly arranged around the mounting plate 1, but it is preferred to arrange three legs in this embodiment. The mounting plate 1 can also be arranged in a square shape, in which case four legs are arranged, and one leg is connected to each side of the square mounting plate 1.

[0028] Specifically, Figure 2 As shown, in this embodiment, three rotating shaft seats 6 are evenly connected at the bottom of the mounting plate 1 through the second bolt 24, a leg connecting shaft 7 is provided on the rotating shaft seat 6, a through hole 41 is provided on the top of the leg, and the leg connecting shaft 7 can move through the through hole 41 to achieve a rotatable connection with the leg.

[0029] The portable geographic information rapid surveying device of this embodiment also includes a push-pull mechanism connected to the bottom of the mounting plate 1, and the push-pull mechanism is used to realize the expansion and contraction of the legs. Specifically, in this embodiment, the push-pull mechanism includes a main shaft rod 9 connected to the bottom of the mounting plate 1, and the main shaft rod 9 is provided with a push ring 12 that can slide along the main shaft rod 9; the push ring 12 is rotatably provided with a plurality of struts 14, and the other end of each strut 14 can be rotatably connected to one of the legs. In this embodiment, as Figure 1As shown, when the push ring 12 is pushed upward along the main shaft 9, the push ring 12 moves upward along the main shaft 9. At this time, the legs are unfolded by the thrust of the support rod 14 to ensure the overall stability of the bracket; when the push ring 12 is pushed downward along the main shaft 9, the push ring 12 moves downward along the main shaft 9. At this time, the legs are retracted by the pulling force of the support rod 14, which is convenient for carrying. By adjusting the distance that the push ring 12 is pushed upward, the unfolding angle of the legs can be adjusted, thereby adjusting the height of the surveying and mapping equipment 3.

[0030] In this embodiment, in order to prevent the push ring 12 from sliding down along the main shaft 9 during use, a locking button 19 is rotatably provided on one side of the push ring 12, and the locking button 19 is used to lock the push ring 12 to prevent the push ring 12 from sliding down. Specifically, the locking button 19 is rotatably connected to a locking column 21, and the main shaft 9 is provided with a plurality of locking holes 10 for the locking column 21 to be movably inserted in sequence along the axial direction. When the push ring 12 is pushed to a desired height, the locking column 21 is inserted into the locking hole 10 at the corresponding height position to prevent the push ring 12 from sliding down along the main shaft 9.

[0031] Specifically, in this embodiment, combined with Figure 3 , Figure 4 As shown, the locking button 19 is a rectangular button with protruding pressing portions 40 at both ends.

Figure 4 As shown in the figure, a baffle 17 is provided at the upper end of the locking button mounting hole 38, and the baffle 17 corresponds to the pressing portion 40 at the upper end of the locking button 19. A first elastic member 20 is provided between the baffle 17 and the pressing portion 40 at the upper end, and the pressing portion 40 at the lower end is rotatably connected to the locking column 21. For example, a pivot (not shown in the figure) can be provided on the inner side of the locking button 19, and then the locking column 21 can be rotatably provided on the pivot, so as to realize the rotational connection between the locking column 21 and the locking button 19. When it is necessary to move the push ring 12, the user presses the pressing portion 40 at the upper end of the locking button 19 by hand, the first elastic member 20 is compressed, the locking button 19 rotates in the locking button mounting hole 38, and the pressing portion 40 at the lower end rotates outward, driving the locking column 21 to disengage from the locking hole 10, and then moves the push ring 12 to the desired position, releases the pressing portion 40 at the upper end, and the first elastic member 20 recovers, pushing the locking button 19 to rotate, and the pressing portion 40 at the lower end rotates inward, pushing the locking column 21 into the locking hole 10, locking the push ring 12 to prevent it from sliding along the main shaft rod 9 again.

[0032] In this embodiment, in order to realize the rotation of the locking button 19, a rotating shaft 39 is provided on both sides of the middle position of the locking button 19, and then, a rotating shaft hole (not shown in the figure) for the rotating shaft 39 to be rotatably inserted is provided on both sides of the middle position of the locking button mounting hole 38.

[0033] In this embodiment, in order to realize the expansion or contraction of the legs, a plurality of first rotating joints 13 are evenly fixedly connected to the radial end surface of the push ring 12, and the number of the first rotating joints 13 is the same as the number of the legs. The other end of each of the first rotating joints 13 is pivotally connected to one end of a strut 14; the other end of the strut 14 is pivotally connected to a second rotating joint 16 through a pivot 15, and the second rotating joint 16 is fixedly connected to the legs. Specifically, when the push ring 12 is pushed upward along the main shaft 9, the first rotating joint 13 moves upward accordingly, and the strut 14 also moves upward and rotates at the same time, and the legs are pushed to expand outward through the second rotating joint 16.
