Problems solved by technology
[0002] At present, there is a tower ruler vertical fixing device, which has high verticality and small measurement error during measurement, but in practical applications, the measurement speed is slow, the occupation time is long, and the measurer is not easy to accept. Therefore, people often use hand-held tower rulers for measurement, and the measurement speed is fast. , Short time occupation, and the effect of rushing to the construction period is remarkable, but it is difficult to avoid large measurement errors by visually controlling the verticality of the tower ruler, and it is not suitable for occasions that require high measurement accuracy.

Embodiment Construction
[0011] The invention is attached figure 1 , 2 As shown in 3, the equipment is composed of clip frame 1, clip 2, tension spring 3 and end rod 4. Clip 2 is connected to clip frame 1. One end of tension spring 3 is connected to clip 3 and the other end is connected to clip frame 1, the end rod 4 is connected to the upper end of the clip 2 (such as Figure 4 Shown). In order to improve the lateral verticality of the tower ruler 5 when measuring, two coaxial lines and end rods 4 perpendicular to the side of the tower ruler 5 are arranged at the upper end of the clamp 2. Point 6 is smaller (e.g. Figure 4 , 5 ) In order to increase the verticality of the tower 5 in the positive direction and reduce the leveling error.
[0012] The method of use of the present invention: pinch the upper end of the clamp 2 with the female finger and index finger, clamp the middle of the upper side of the center of gravity of the tower ruler 5, hold the end rod 4 with two fingers to keep it as horizontal ...

A sliding staff clamp capable of improving sliding staff perpendicularity and reducing measurement height difference errors comprises a clamp frame, a clamp, a tension spring and an end rod, wherein the clamp is connected with the clamp frame, one end of the tension spring is connected with the clamp, the other end of the tension spring is connected with the clamp frame, and the end rod is connected with the upper end of the clamp. The sliding staff clamp provided by the invention is simple in structure, convenient in operation, less in investment, distinct in effect, strong in practicabilityand low in cost, and is a practical item with high value of popularization.
Description
Technical field [0001] The invention relates to a tower ruler clamp for improving the verticality of the tower ruler and reducing the error of the measurement height difference, in particular to a tower ruler equipment that uses the tower ruler to measure the height difference to reduce the error for construction projects. Background technique [0002] At present, there is a tower ruler vertical fixing device, which has high verticality during measurement and small measurement error. However, in practical applications, the measurement speed is slow, the occupation time is long, and the surveyor is not easy to accept. Therefore, people often use the tower ruler to measure, and the measurement speed is fast , The occupation time is short, and the effect of rushing to the construction period is obvious. However, it is difficult to avoid large measurement errors by visually controlling the verticality of the tower ruler, and it is not suitable for occasions that require high measureme...
