Description

Technical Field

[0001] This utility model relates to an eccentric instrument, specifically an eccentric instrument with good fixing effect, and belongs to the field of eccentric instrument technology. Background Technology

[0002] An eccentricity meter is an instrument widely used in the processing of optical components and optical assembly. It can be used to measure the different axialities of the optical axis and outer circle of a spherical lens for easy calibration. During measurement, the observation head must first be adjusted to a specific position so that the spherical center image of the lens under test can be observed through the eyepiece.

[0003] Chinese patent application publication number CN213422588U discloses an eccentricity device with good fixation effect. This eccentricity device changes the horizontal position of the detection device by pushing a moving block, and rotates a crossbar support by tightening a locking bolt. The crossbar support transmits power to the detection device, thereby changing the vertical position of the detection device. It is simple to operate and easy to use.

[0004] Although the solutions in the aforementioned patents can change the vertical position of the detection device, the eccentricity in the aforementioned patents is not convenient for adjusting the working distance of the positioning device according to the working environment. The positioning device of most eccentricities is fixed, which can easily cause the center of gravity of the eccentricity to be unstable and affect the use effect of the eccentricity. Therefore, an eccentricity with good fixing effect is proposed here. Utility Model Content
