The measuring rod body is arranged in the middle of the bottom of the supporting device, and the clamping device is arranged on the top of the supporting device. When the technical solution is in use, the supporting device can stably support it on the ground after the supporting device is unfolded, and the clamping device can clamp related measuring instruments, which facilitates measurement and improves efficiency. With respect to the above technical solution, although the solution can clamp the measuring instrument, it is impossible to mark the aiming point after aiming, and it is impossible to quickly find the marked point in the later stage, which is inconvenient when used.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] See also Figures 1 to 8 The utility model provides a technical solution: a measuring rod for engineering surveying and mapping, comprising a measuring rod body, the measuring rod body comprising a movable tube 1 and a fixed rod 15, a support rod 3 is movably installed inside the movable tube 1, and a pigment layer is smeared and fixed on the surface of the support rod 3 and the movable tube 1, a fixing column 2 is fixed at the bottom of the movable tube 1, a fixing hole 4 is opened at the top of the movable tube 1, one end of the fixing column 2 is movably installed inside the fixing hole 4, a fixing groove 8 is opened on the support rod 3, a movable plate 9 is movably installed inside the fixing groove 8, a limiting column 11 is welded on the inner wall of the movable tube 1, a limiting groove 10 is opened on one side of the fixing groove 8, the limiting column 11 is movably installed inside the limiting groove 10, and a cutting 7 is welded at the bottom of the support rod 3, and the cutting 7 facilitates the support rod 3 to be inserted into the ground for limiting fixation.

[0025] In this embodiment, a groove 12 is formed on the inner wall of the fixing groove 8, and a supporting mechanism 13 is fixed inside the groove 12. The supporting mechanism 13 is a supporting spring, which provides supporting force for the movable column 14. A movable column 14 is fixed to one end of the supporting mechanism 13, and one end of the movable column 14 is connected to the movable plate 9. An opening 5 is formed on the top of the supporting rod 3, and an extrusion plate 6 is movably installed inside the opening 5. A connecting column 16 is welded to one end of the fixing rod 15, and a fixing plate 18 is welded to one end of the connecting column 16. The fixing plate 18 is movably installed inside the opening 5. A clamping column 19 is welded on the fixing plate 18. A clamping hole 17 is formed on the inner wall of the opening 5, and one end of the clamping column 19 is movably installed inside the clamping hole 17. The extrusion plate 6 is installed inside the opening 5 through a reset mechanism 20, and the reset mechanism 20 is a spring. The spring pushes the extrusion plate 6 to move upward, thereby squeezing the fixed plate 18 upward through the extrusion plate 6.

[0026] When the device is in use, the support rod 3 is first inserted into the ground through the insertion 7 for limit fixing, and the measurement and aiming are carried out by cooperating with the support rod 3 and the movable tube 1 through the measuring instrument. After the measurement and aiming, the movable tube 1 is rotated on the support rod 3, and the movable tube 1 is rotated to separate the limit column 11 from the inside of the limit groove 10. After separation, the movable tube 1 is pushed downward as a whole, and the bottom movable tube 1 is pushed to be inserted into the ground through the fixed column 2. The fixed column 2 provides a support and fixing point for the movable tube 1. When the bottom movable tube 1 is fixed on the ground, the remaining movable tube 1 is rotated again to make the limit column 11 enter the internal limit of the limit groove 10. When limiting, the limit column 11 is supported and limited by the movable plate 9. A plurality of movable tubes 1 are inserted into the measuring points, which is convenient for locating and searching the measuring points later. When the measuring height of the support rod 3 needs to be extended, the connecting column 16 on the fixing rod 15 pushes the fixing plate 18 to be installed inside the opening 5. The fixing plate 18 moves downward to squeeze the squeezing plate 6. The squeezing plate 6 shrinks to the bottom of the opening 5. The fixing rod 15 drives the fixing plate 18 to rotate. After the rotation, the clamping column 19 enters the bottom of the clamping hole 17. Then the fixing rod 15 is released, the squeezing plate 6 restores the supporting force, and the squeezing plate 6 is pushed by the reset mechanism 20. The squeezing plate 6 pushes the fixing plate 18 to move downward as a whole. When it moves upward, the clamping column 19 enters the inside of the clamping hole 17 to limit and fix the fixing rod 15.
