[0021] Hereinafter, an embodiment of a fixing clamp for a hand-held surveying instrument attachment bracket of the present invention will be described with reference to the accompanying drawings.
[0022] Figure 1-4A hand-held surveying instrument attachment bracket fixing clamp of an embodiment of the utility model is shown, comprising a lower bracket 1: a slidable upper bracket 2 is arranged on the back surface of the lower bracket 1, the inner cavities of the lower bracket 1 and the upper bracket 2 are both bonded with soft pads 16, the soft pads 16 are foam pads, a rotating rod 3 is fixedly connected to the rear side of the lower bracket 1, the top and bottom of the back surface of the lower bracket 1 are both fixedly connected to fixed blocks 4, the bottom of the back surface of the upper bracket 2 is fixedly connected to a threaded sleeve 5, the inner cavity of the threaded sleeve 5 is threadedly connected to a threaded rod 6, the top and bottom of the surface of the threaded rod 6 are rotatably connected to the two fixed blocks 4 respectively, through the fixed blocks 4, The threaded sleeve 5 and the threaded rod 6 are used in combination to adjust the use height of the upper bracket 2, so that the upper bracket 2 can cooperate with the lower bracket 1 to clamp and fix the thin-film surveying instrument 20, so that the thin-film surveying instrument 20 can be stably placed in the inner cavity of the lower bracket 1, and at the same time, the lower bracket 1 and the upper bracket 2 can be adapted to install thin-film surveying instruments 20 of different sizes. The right side of the rotating rod 3 is fixedly connected with a rotating handle 19, and the left side of the rotating rod 3 is provided with a fixing sleeve 7. The two sides of the top of the back surface of the lower bracket 1 are fixedly connected with the limit pins 17, and the two sides of the back surface of the fixing sleeve 7 are provided with a space suitable for the limit pins 17. The left end of the rotating rod 3 is fixedly connected with a rotating disk 8, and the rotating disk 8 is rotatably connected to the inner cavity of the fixed sleeve 7. The top and bottom of the fixed sleeve 7 are fixedly connected with a fixed tube 9 connected to the fixed sleeve 7. The inner cavity of the fixed tube 9 is provided with a card ball 10. The surface of the rotating disk 8 is annularly provided with an arc-shaped card groove 11 adapted to the card ball 10. The surface of the card ball 10 is welded with a spring 12. The end of the spring 12 away from the card ball 10 is welded to the fixed tube 9. The left side of the fixed sleeve 7 is fixedly connected with a first clamp 13, and the left side of the first clamp 13 is provided with a second clamp 14. The first clamp 13 and the second clamp 14 are provided. The two clamps 14 are both sleeved on the surface of the RTK host bracket, and bolts 15 are penetrated at the front and rear ends of the left side of the second clamp 14. The first clamp 13 and the second clamp 14 are tightly clamped on the surface of the RTK host bracket by the bolts 15. Through the coordinated use of the first clamp 13, the second clamp 14 and the bolts 15, the fixing sleeve 7 can be stably installed on the surface of the RTK host bracket, so that the rotating rod 3, the lower bracket 1 and the upper bracket 2 can drive the hand-held surveying instrument 20 to be stably installed on the surface of the RTK host bracket, and the inner cavities of the lower bracket 1 and the upper bracket 2 clamp the hand-held surveying instrument 20.
[0023] Working principle: When the utility model is used, the user first sets the first clamp 13 and the second clamp 14 on the surface of the bracket, and tightens and fixes them by bolts 15, then prevents the hand-held surveyor 20 from being started inside the lower bracket 1, and then rotates the threaded rod 6. The threaded rod 6 pushes the threaded sleeve 5 through the thread on its surface during the rotation process, so that the upper bracket 2 slides downward, so that the upper bracket 2 is pressed on the top of the hand-held surveyor 20, so that the hand-held surveyor 20 can be clamped and fixed. When in use, the user faces the hand-held surveyor 20 and rotates the handle 19. The handle 19 drives the rotating rod 3 during the rotation process. The rotating rod 3 rotates, and the rotating rod 3 drives the orientation angle of the thin-film surveying device 20 to be adjusted through the cooperation of the lower bracket 1 and the upper bracket 2 during the rotation, so that the user can check and operate the thin-film surveying device 20. During the rotation of the rotating rod 3, the turntable 8 rotates in the inner cavity of the fixed sleeve 7. During the rotation, the turntable 8 moves the card ball 10 through the arc-shaped card groove 11. Under the elastic force of the spring 12, the card ball 10 actively engages with the inner cavity of different arc-shaped card grooves 11 until the rotating rod 3 stops rotating. The card ball 10 engages in the inner cavity of the current arc-shaped card groove 11, and the orientation angle of the thin-film surveying device 20 is positioned.
[0024] In summary: the hand-held surveyor 20 is clamped and fixed by the bracket fixing clamp attached to the lower bracket 1, the upper bracket 2 and the threaded rod 6. At the same time, the rotating rod 3, the turntable 8 and the fixing sleeve 7 are used in cooperation to adjust the orientation angle of the hand-held surveyor 20. Finally, with the cooperation of the second clamp 14 and the bolt 15, the hand-held surveyor 20 can be attached and installed on the surface of the RTK host bracket, so as to achieve the purpose of easy adjustment of the orientation angle, simple and convenient installation and wide range of adaptability.
