[0002] As is well known, the total station support is a key piece of equipment for supporting and fixing the total station in surveying work, and its stability and accuracy directly affect the reliability of the measurement results. It is mainly divided into: tripods, triangular bases, magnetic supports, and vehicle-mounted supports, etc.

[0003] A utility model patent with patent authorization announcement number CN220770726U discloses an engineering surveying total station bracket, including a connecting plate. A set of positioning rods is fixedly connected to the bottom surface of the connecting plate. A positioning cylinder is sleeved on the outer surface of each positioning rod. A fixing rod is fixedly connected to the outer surface of each positioning cylinder. A rolling bearing is fixedly embedded in the bottom surface of the connecting plate. A threaded cylinder is fixedly connected to the inner ring of the rolling bearing.

[0004] However, existing total station supports also have certain shortcomings. Most existing total station supports simply use a combination of components such as elastic damping and deflection shafts to limit the deflection of the support. Due to factors such as vibration and impact, the support is prone to deflection, making it inconvenient to carry and use later. Utility Model Content

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A foldable and portable total station support includes a support base 1. Three connecting seats 2 arranged in a circular array are fixedly connected to the side of the support base 1. A support shaft 3 is rotatably connected to the inner wall of each connecting seat 2. A support column 4 is fixedly sleeved on the outer side of the support shaft 3. An clearance hole 5 is opened at the lower end of the support column 4. A threaded hole 6 is opened on the inner wall of the support column 4. The threaded hole 6 communicates with the clearance hole 5. A screw rod 7 is threadedly connected to the inner wall of the threaded hole 6. The screw rod 7 is movably connected to the clearance hole 5. A connecting block 8 is fixedly connected to the lower end of the screw rod 7. The connecting block 8 is movably connected to the clearance hole 5. A pointed cone 10 is fixedly connected to the lower end of the connecting block 8.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4Multiple rubber blocks 9 are fixedly connected to the surface of the connecting block 8. The multiple rubber blocks 9 are evenly distributed on the connecting block 8. The setting of the rubber blocks 9 makes it easy to push the connecting block 8 to rotate. Multiple friction grooves 11 are opened on the surface of the cone 10. The multiple friction grooves 11 are evenly distributed on the cone 10. The setting of the friction grooves 11 can improve the friction effect of the surface of the cone 10.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A folding mechanism 12 is provided on both the support shaft 3 and the connecting seat 2. The folding mechanism 12 includes an insertion hole 120. The end surface of the support shaft 3 is provided with an insertion hole 120. A guide rod 121 is fixedly connected to the end face of the connecting seat 2 away from the support seat 1. A baffle 122 is fixedly connected to the other end of the guide rod 121. A movable piece 123 is slidably sleeved on the outside of the guide rod 121. An insertion rod 124 is fixedly connected to the end face of the movable piece 123 near the support shaft 3. The insertion rod 124 is slidably connected to the insertion hole 120. A spring 125 is provided on the outside of the guide rod 121. Under the action of the insertion hole 120, the insertion rod 124 and other structures, the support shaft 3 can be inserted and used, so that the support shaft 3 drives the support column 4 to be stable.

[0026] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 Multiple insertion holes 120 are provided, and the multiple insertion holes 120 are arranged in a ring array on the end of the support shaft 3. The insertion holes 120 facilitate the insertion of the insertion rod 124. Multiple semi-circular grooves are opened on the surface of the movable piece 123. The multiple semi-circular grooves are evenly distributed on the movable piece 123. The semi-circular grooves facilitate the movement of the movable piece 123. One end of the spring 125 is welded to the baffle 122, and the other end of the spring 125 is welded to the movable piece 123. The spring 125 can be used to tighten the movable piece 123.

[0027] The specific implementation process of this utility model is as follows: In use, by pushing the rubber block 9 to rotate, the connecting block 8 is driven to rotate, which in turn drives the screw 7 to rotate. Under the threaded connection, the screw 7 can rotate and move upward along the inner wall of the threaded hole 6, and drive the connecting block 8 to rotate and move upward, which in turn drives the cone 10 to rotate and move upward. The exposed lengths of the connecting block 8 and the cone 10 are adaptively adjusted to facilitate subsequent carrying and use.

[0028] By pulling the movable piece 123 away from the connecting seat 2, the movable piece 123 slides along the surface of the guide rod 121. Under the action of the baffle 122, the spring 125 deforms and drives the insertion rod 124 to move, causing the insertion rod 124 to disengage from the insertion hole 120. Then, the support column 4 is pushed to deflect, thereby driving the support shaft 3 to rotate. The support column 4 is folded for use, and the movable piece 123 is released to allow the spring 125 to return to its original deformation, so that the movable piece 123 drives the insertion rod 124 to insert into the next insertion hole 120. The support shaft 3 is limited, so that the support shaft 3 drives the support column 4 to be stable, avoiding the deflection problem caused by the vibration and impact of the support column 4.
