Working principle: When in use, the user can move the outer foot rod to expand the support and place the bracket, and then can observe the horizontal observation of the bracket placement through the provided bubble level, and can measure the length of the foot rod according to the inclination of the bubble level in different directions. When adjusting the foot rod, the rotation of the fine-tuning disk can be unlocked by rotating the locking screw, and then the fine-tuning disk can be rotated to make the fine-tuning disk drive the screw to rotate. At this time, since the outer foot rod is not connected to the screw, While the inner leg rod is threadedly connected to the screw rod, the inner leg rod can only be raised and lowered but cannot be rotated, while the screw rod itself can only be rotated but not raised and lowered, resulting in the inner leg rod that is threadedly connected to the screw rod when the screw rod rotates. The lifting movement of the foot rod, and because the thread is continuous, the lifting and lowering of the inner foot rod can accurately stay at the relative height position with the rotation of the screw, so that the user can perform more fine adjustment of the horizontal placement of the bracket, and after the user adjusts After that, you can rotate the locking screw to make the locking screw press against the elastic ring to lock the rotation of the fine-tuning disk, so as to better prevent the random rotation of the fine-tuning disk after adjustment, ensure the accurate and stable placement of the bracket, and enable the subsequent assembly of the surveying and mapping instrument. After that, the surveying and mapping accuracy of the surveying and mapping equipment can be better improved, and when the equipment needs to be placed on a smooth surface, the user can pull the rough support sleeve so that the rough support sleeve will push the movable clamp inward and be pulled out conveniently. The equipment is directly supported by the bottom of the inner foot rod, and the bottom of the inner foot rod is provided with a rotatable anti-skid assembly plate, and the anti-skid assembly plate is covered with a non-slip pad with a suction groove, so that the equipment can be stabilized by the anti-skid pad and suction groove The assembly of the device is used on a smooth surface, and can be restored by directly inserting it back into the rough support sleeve after use, avoiding the inconvenience of carrying and assembling the anti-skid pad, which is convenient for the placement and use of the device on different grounds.
