[0028] Please see Figure 1-4 This utility model provides a folding surveying instrument mounting bracket, comprising:

[0029] Mounting base 1;

[0030] The main support arm 2 has three main support arms 2, which are arranged around the side wall of the mounting base 1. The main support arm 2 has a receiving groove 21, and a rotating shaft 22 is rotatably provided between the two side walls of the receiving groove 21.

[0031] A secondary support arm 3 is fixedly sleeved on the rotating shaft 22;

[0032] Support leg 4 is slidably disposed inside the auxiliary support arm 3;

[0033] Locking mechanism 5 is installed on the main support arm 2 and is used to lock the position of the auxiliary support arm 3.

[0034] With the above structure, after use, the auxiliary support arm 3 can be easily folded into the receiving slot 21 of the main support arm 2. The volume of the folded bracket is greatly reduced, significantly improving the portability of the bracket and making it easier and more efficient for staff to carry surveying equipment to different work locations.

[0035] The locking mechanism 5 includes two receiving shells 51, both of which are fixedly mounted on the outer wall of one side of the main support arm 2. A wedge-shaped limiting block 52 is slidably provided inside the receiving shell 51. A pull rod 53 is fixedly connected to one side wall of the wedge-shaped limiting block 52. The other end of the pull rod 53 extends to the outside of the receiving shell 51. A spring 54 is provided between one side wall of the wedge-shaped limiting block 52 and one side inner wall of the receiving shell 51.

[0036] By setting up the above structure, the position of the secondary support arm 3 can be locked in different states. When the secondary support arm 3 is in the folded state, the locking mechanism 5 can prevent it from being accidentally unfolded. When in use, the locking mechanism 5 can ensure that the secondary support arm 3 is stably supported, thereby enhancing the structural strength and stability of the entire bracket.

[0037] The auxiliary support arm 3 has a first limiting groove 31 and a second limiting groove 32 adapted to the wedge-shaped limiting block 52 on one side wall.

[0038] The auxiliary support arm 3 is equipped with a locking bolt 33 for locking the position of the support leg 4. After adjusting the support leg 4 to make the bracket horizontal, rotating the locking bolt 33 can press the support leg 4 inside the auxiliary support arm 3, thereby fixing the support leg 4 and preventing it from sliding.

[0039] One end of the support leg 4 is fixedly connected to a ground nail 41. After the ground nail 41 is inserted into the ground, it can improve the stability of the support.

[0040] One end of the support leg 4 is fixed with a foot pedal 42, which makes it easy to press the ground nail 41 into the ground by stepping on the foot pedal 42.

[0041] One of the main support arms 2 has a Velcro strap 6 on one side of its outer wall, which can tie the three main support arms 2 together to prevent the main support arms 2 from unfolding.

[0042] It should be noted that this utility model is a folding surveying instrument mounting bracket. In use, the Velcro strap 6 is untied, and then the pull rod 53 located inside the upper receiving shell 51 is pulled. The pull rod 53 will pull the wedge-shaped limiting block 52 into the receiving shell 51, causing the wedge-shaped limiting block 52 to disengage from the second limiting groove 32 of the secondary support arm 3. Then, the secondary support arm 3 can be rotated to unfold it. During unfolding, the secondary support arm 3 will press against the lower wedge-shaped limiting block 52. The inclined surface of the wedge-shaped limiting block 52 will be compressed by the secondary support arm 3, causing the wedge-shaped limiting block 52 to retract into the receiving shell 51 and compress the spring 54, making room for the secondary support arm 3. When the secondary support arm 3 is fully unfolded, the first limiting groove 31 aligns with the receiving shell 51, so that the wedge-shaped limiting block 52 is no longer compressed. Then, the wedge-shaped limiting block 52 will be pushed into the first limiting groove 32 by the spring 54. Lock the secondary support arm 3 in the slot 31. Unfold the remaining secondary support arms 3 in the same way. Then, install the surveying instrument on the mounting base 1 and use a level to check if it is level. If it is not level, loosen the locking bolt 33 so that the support leg 4 can slide to adjust the level. After adjustment, tighten the locking bolt 33 to lock the position of the support leg 4. After use, pull the pull rod 53 in the lower housing 51 to disengage the wedge-shaped limit block 52 from the first limit slot 31. Then, fold the secondary support arm 3 into the housing slot 21 of the main support arm 2. The wedge-shaped limit block 52 above locks the secondary support arm 3 to prevent it from unfolding. Fold the remaining secondary support arms 3 into the corresponding housing slot 21 of the main support arm 2 in the same way to greatly reduce the volume of the bracket. Then, use Velcro straps 6 to tie the three main support arms 2 together.
