[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0023] Example

[0024] Figures 1-4 What is shown is a schematic diagram of the overall structure of a specific embodiment of the utility model. Figures 1-4 A portable surveying and mapping bracket includes a supporting mechanism and a telescopic mechanism.

[0025] The supporting mechanism includes a supporting plate 1, a fixed block 2, a rotating rod 3, and a clamping frame 10. The fixed block 2 is installed at the lower end of the supporting plate 1, the rotating rod 3 is installed between the two fixed blocks 2, and the rotating rod 3 is installed on one side of the two fixed blocks 2.

[0026] The telescopic mechanism includes a support tube 4, a middle adjusting bolt 5, a limiting ring 6, and a bottom adjusting bolt 7. The middle adjusting bolt 5 is threadedly connected to the middle of the support tube 4, and the bottom adjusting bolt 7 is threadedly connected to the middle of the middle adjusting bolt 5. The limiting ring 6 is installed at the lower end of the middle adjusting bolt 5, and the bottom adjusting bolt 7 is plugged into the limiting ring 6.

[0027] Among them, one end of the support tube 4 away from the middle adjustment bolt 5 is plugged into the rotating rod 3, and the clamping frame 10 is clamped and connected to the support tube 4.

[0028] When the device is in use, first adjust the use position of the support tube 4 under the rotation support of the fixing block 2 and the rotating rod 3, then rotate the middle adjusting bolt 5 to extend its length, and then extend the bottom adjusting bolt 7 to adjust the overall height of the support, and then adjust the support parts below in turn to adjust the support plate 1 to a horizontal level to ensure its accuracy during use. At the same time, since the connection method of the support tube 4 and the middle adjusting bolt 5, and the middle adjusting bolt 5 and the bottom adjusting bolt 7 are set to be threaded, it can play a limiting effect while adjusting the support height, so that it can be fixed and supported at the same time as the height is adjusted, and it is convenient to store it, thereby improving its stability and firmness when supporting use, improving its convenience and rationality when storing and moving, reducing its occupied space, and facilitating its movement and carrying. Adaptively, under the clamping of the clamping frame 10 to the support tube 4, the stored support tube 4 can be limited and placed, further improving the stability and reliability of the placement of the device after storage.

[0029] Figure 2 and Figure 3 In the figure, the telescopic mechanism also includes a support block 8, a placement block 9, and an anti-slip strip 11. The placement block 9 is installed at the lower end of the support block 8, and at least two support blocks 8 are installed on one support block 8. The anti-slip strip 11 is installed at the lower end of the support block 8.

[0030] A rotating rod 3 is installed between the two supporting blocks 8 , and the rotating rod 3 is plugged into the lower half of the bottom adjusting bolt 7 .

[0031] There are a plurality of anti-slip strips 11 , and the anti-slip strips 11 are distributed parallel to the rotation direction of the placement block 9 .

[0032] Under the connection of the support block 8, the rotating rod 3 and the bottom adjustment bolt 7, the support angle of the placement block 9 can be adjusted in time so that the anti-slip strip 11 at its lower end can fully contact the support surface, and under the anti-slip support of the anti-slip strip 11, the stability and reliability of the support component when extending the support are guaranteed, and its stability when supporting is used is guaranteed.

[0033] Figure 3 In the embodiment, every two fixing blocks 2 form a group for rotation support, and there are at least three groups of fixing blocks 2, and at least three supporting tubes 4.

[0034] With the rotational support of the three support cylinders 4 by the three groups of fixed blocks 2, the angle stability of each support cylinder 4 is guaranteed when it moves, and when the three support cylinders 4 and the support plate 1 are used for support, multiple triangular support structures can be formed, further providing stability when the device is supported.

[0035] Figure 4 There are at least three clamping frames 10, and the clamping frames 10 are used to accommodate the limit of the rear telescopic mechanism.

[0036] The three clamping frames 10 limit and clamp the three support tubes 4 respectively, thereby improving the fastening stability of the device when in use, ensuring the convenience of storing and moving the device, and further saving the space actually occupied by the device.

[0037] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
