[0002] The support rod is used to support the measuring instrument in mine surveying work to ensure that it remains stable and accurate during the measurement process.

[0003] When using a bracket rod body to support the surveying instrument during mine surveying work, the mounting slot on the surveying instrument is usually screwed onto the threaded block on the bracket rod body, and then the bracket rod body is stretched out to support and fix it. When the surveying instrument is hit by external force during surveying, it may cause the surveying instrument to shake and rotate, causing the mounting slot and the threaded block to slip and fall off, affecting subsequent use. Utility Model Content

[0013] Preferably, a plurality of anti-sliding blocks are fixedly connected to one side of the limiting rod, and the plurality of anti-sliding blocks are made of rubber material.

[0014] The effect achieved by the above components is: by providing the anti-sliding block, the contact friction force on one side of the limit rod can be increased, making it more firm and stable when the surveying and mapping instrument is limited and fixed.

By setting the magnet block 26, after the iron rod 25 is inserted into the first clamping hole 23 and the second clamping hole 24 to a certain position, one side will be adsorbed and fixed by the magnet block 26, so that it is clamped more firmly and not easy to slide out. A connecting rope 27 is fixedly connected to one end of the iron rod 25, and one end of the connecting rope 27 is fixedly connected to one side of the slide slot rod 21. By setting the connecting rope 27, the iron rod 25 can be limited and fixed on one side of the slide slot rod 21, so that it is not easy to be lost after being pulled out of the first clamping hole 23 and the second clamping hole 24.
