In order to realize the above purpose, the utility model discloses a technical scheme be: a precise level comprises a level body, wherein an objective lens and an eyepiece are fixedly mounted on two sides of the level body respectively, the objective lens and the eyepiece lens are connected with the objective lens and the eyepiece lens respectively, the objective lens is matched with the objective lens, the objective lens and the eyepiece lens form a focusing screw and a focusing screw, a bubble observation mirror arranged on a shell is mounted on one side of the eyepiece lens, a level pipe arranged in the shell is mounted between the eyepiece lens and the objective lens, a cover plate provided with a through hole is fixedly mounted at the center of the top end of the eyepiece lens, the through hole in the cover plate and a sight bead at the top end of the objective lens are on the same axis and are positioned in the same plane, a correcting screw is connected to one side of the outer wall of the level body through a circular level, a triangular bottom plate is mounted at the bottom end of the level body, the triangular bottom plate is connected, joint portion inner wall is equipped with anticreep groove, joint portion one end is close to the mounting hole that connects on the roof and be the triangle setting, and the mounting hole corresponds with the screw hole aperture on the roof and is connected and realize locking fixedly through foot spiral.
Furthermore, a horizontal micro-motion spiral and a micro-inclination spiral which are positioned between the objective lens and the eyepiece are arranged on one side of the outer wall of the level body.
Furthermore, a horizontal brake screw arranged on the shell is arranged on the horizontal micro-motion screw.
Furthermore, a shaft seat is fixedly arranged on the foot spiral close to the shell.
Furthermore, a reinforcing surface connected with an external top plate is fixedly installed at the center of the bottom end of the triangular bottom plate.
The technical effects of the utility model reside in that: the sight on the objective and the cover plate with the through hole on the eyepiece are positioned on the same axis, which can effectively align the front and the rear reference objects in the horizontal direction, meanwhile, the arrangement of the bubble observation mirror on the eyepiece can see whether the level bubble is centered or offset, when the position of the level tube in the shell deviates, the leveling can be performed by the correcting screw on the circular level, when the triangular bottom plate on the device is fixedly installed with the external tripod, the triangular bottom plate is firstly clamped and fixed through the anti-drop groove on the clamping part, and then is screwed and fixed through the mounting hole and the foot screw on the external threaded hole, and the height of the device can be adjusted, so that the practicability of the device is greatly improved, the measuring precision is high, carry out the level of referring to the thing through the sight component and aim at, connect stably, the installation of being convenient for is dismantled, adjusts conveniently, and is functional strong.
