[0002] During the use of a total station gyroscope, the stability and ease of adjustment of the bracket directly impact measurement accuracy. Existing brackets often suffer from issues such as cumbersome support angle adjustment, asynchronous extension and retraction of multiple support legs, and low overall adjustment efficiency. Traditional brackets require manual adjustment of the support leg angle and extension length, a complex operation that makes it difficult to ensure consistency between the legs. This results in poor overall bracket stability, especially in environments with complex terrain. Adjustment is time-consuming, impacting measurement efficiency. Utility Model Content

[0003] The technical problem to be solved by the utility model is that the support angle and telescopic adjustment of the existing bracket are not synchronized, the operation is cumbersome, and the stability is insufficient. The utility model realizes efficient synchronous adjustment of the gyroscope bracket of the total station, and improves the support stability and the convenience of operation.

[0010] As an improvement, the main support arm is provided with a connection groove 1 for sliding connection with the sliding column on the middle support arm, and a connection groove 2 for sliding connection with the sliding column on the inner support arm is reserved. The middle support arm is provided with a connection groove 3 for sliding connection with the sliding column on the inner support arm, and the connection groove 3 is connected with the connection groove 2.

[0011] The advantages of this utility model compared with the prior art are:

Rotating the rotating handle 6 drives the threaded rotating rod 54 to rotate, and the threaded rotating rod 54 drives the toothed tube 52 to rise and fall along the connecting block 51, and the toothed tube 52 drives the transmission connection tube 4 to rise and fall through the transmission gear 53, and the transmission connection tube 4 drives the main support arm 3 to rotate synchronously by engaging with the transmission teeth 31, thereby realizing synchronous adjustment of the support angle.

[0028] A central threaded barrel 7 is fixed at the center of the bottom end of the fixed connecting plate 1, and the external thread of the central threaded barrel 7 is connected to a swivel adjustment mechanism 8. The swivel adjustment mechanism 8 includes a swivel 81 which is sleeved on the outside of the central threaded barrel 7. The swivel 81 is threadedly matched with the central threaded barrel 7. The middle part of the swivel 81 is rotatably connected to a built-in fixed ring 82 through a T-shaped slot 812. A number of connecting ear plates 83 are fixed on the built-in fixed ring 82. The upper and lower layers of connecting ear plates 83 correspond one-to-one to the main support arm 3 and the central support arm 91. A friction tooth pattern 811 is provided on the swivel 81 to facilitate the rotation operation.

[0029] Please see the attached Figure 2 , Attachment Figure 5 and attached Figure 8 As shown, a multi-stage telescopic leg mechanism 9 is provided in the main support arm 3, and the multi-stage telescopic leg mechanism 9 includes a central support arm 91 which is slidably sleeved in the main support arm 3, an inner support arm 92 which is slidably sleeved in the central support arm 91, and a fixed support foot 93 is provided at the bottom end of the inner support arm 92; a baffle 1 94 is provided on the top of the central support arm 91 and the inner support arm 92, and a baffle 2 95 is provided at the bottom end of the main support arm 3 and the central support arm 91, and baffle 1 94 cooperates with baffle 2 95 to prevent excessive telescopic separation; a sliding column 96 is provided on the side of the central support arm 91 and the inner support arm 92 close to the central threaded tube 7, and a hinge seat 97 is connected to the sliding column 96, and a connecting arm 98 is connected between the hinge seat 97 and the connecting ear plate 83.

[0030] The main support arm 3 is provided with a connecting groove 1 32 and a connecting groove 2 33, for sliding the slide post 96 of the middle support arm 91 and the inner support arm 92 respectively. The middle support arm 91 is provided with a connecting groove 3 911, which is connected with the connecting groove 2 33 to allow the slide post 96 of the inner support arm 92 to slide. When the swivel 81 is rotated, the swivel 81 rises and falls along the middle threaded cylinder 7. Since the connecting ear plate 83 fixed on the outer wall of the built-in fixed ring 82 is connected to the hinge seat 97 through the connecting arm 98, the hinge seat 97 is fixed to the middle by the sliding post 96. On the support arm 91 and the inner support arm 92, so when the swivel 81 rotates and moves up and down, under the rotational connection between the T-shaped slide groove 812 and the built-in fixed ring 82, the swivel 81 moves up and down, driving the built-in fixed ring 82 to move up and down, and the built-in fixed ring 82 will not rotate. When the built-in fixed ring 82 moves up and down, it pulls the hinge seat 97 through the connecting ear plate 83 and the connecting arm 98, causing the slide column 96 to slide along the connecting groove, driving the middle support arm 91 and the inner support arm 92 to extend and retract synchronously, thereby realizing multi-stage support leg length adjustment.

[0032] To fine-tune the height, individually rotate the corresponding swivel 81 (the multiple swivel adjustment mechanisms 8 can be operated independently), which in turn drives the individual multi-stage telescopic leg mechanisms 9 to extend and retract via the connecting lugs 83, ensuring horizontal stability. After use, reverse the swivel 81 to retract the multi-stage telescopic leg mechanisms 9, and reverse the handle 6 to fold the main support arms 3 for easy storage and portability.
