Technical Field

[0001] The utility model belongs to the technical field of measuring tools, and in particular relates to a multifunctional measuring device. Background Art

[0002] Engineering surveying instruments are a type of surveying instrument that is required for various types of orientation, distance, angle, height, mapping, and photogrammetry work during the planning, design, construction, and management stages of engineering construction.

[0003] Through patent search, it was found that a coincidence measuring instrument for the center of the power tower foundation pile and the center of the anchor bolt with publication number CN110243266A includes a base, at least two positioning rods are fixedly connected to the bottom end of the base, and the positioning rods are provided with a fine-tuning bolt body perpendicular to the positioning rods at the end away from the base. A measuring module capable of multi-directional ranging is provided on the base, and the extension direction of the measuring module is parallel to the top surface of the base. The coincidence measuring instrument uses a leveling module arranged at the bottom end of the base and a measuring module axially mounted on the top end of the base. The leveling module can be operated to arbitrarily adjust the measuring direction of the measuring module while keeping the base in a horizontal state. It has high flexibility, greatly improves the measurement efficiency, and can be completed by a single person.

The springs 102 are fixedly connected with ball seats 15 on the side close to the clamping balls 103. The clamping balls 103 are rotatably connected in the ball seats 15. The design of the ball seats 15 makes the clamping balls 103 rotate, which is conducive to reducing the friction between the clamping balls 103 and the side openings 8.
