The invention discloses a fixing-strengthened three-claw foundation bed used for various optical plummets. The fixing-strengthened three-claw foundation bed comprises a foundation bed body, wherein three claw holes are formed in a circular disk in the middle of the foundation bed body, and used for insertion of the optical plummets so as to be in butt joint; a first slide rail is arranged on the bottom of each claw hole; the claw holes can slide on the first slide rail to be used for regulating the positions of the three claw holes; more than two second slide rails (excluding the three first slide rails) are further arranged in the circular disk in the middle of the foundation bed body, optical plummet fixing devices are arranged on the slide rails, can slide on the second slide rails and can be used for regulating the positions of the optical plummet fixing devices. The fixing-strengthened three-claw foundation bed disclosed by the invention has the advantages that the foundation bed is applicable to various models of optical plummets by regulating positions of the claw holes, so that using efficiency is greatly improved; the movable and telescopic optical plummet fixing devices can be arranged for fixing the various models of optical plummets.
Description
technical field [0001] The invention relates to the field of three-claw bases, in particular to a widely-used three-claw base suitable for various types of optical plummets with enhanced fixation. Background technique [0002] The three-claw base is widely used in various surveying instruments, theodolites, total stations, levels, etc., and is used to insert the optical plummet on it, so as to connect and fix the optical plummet. The existing optical plummet usually has The triangular pin is connected to the claw hole in the three-claw base for docking and fixing through the triangular pin. The existing three-claw bases are usually fixed in type, each three-claw base is only suitable for a corresponding type of optical plummet, and the scope of use is limited, thus reducing the efficiency of use; at the same time, the optical plummet and The connection of the three-claw base is only through plug-in connection, the connection is not firm enough, and it is easy to loosen and ...
