Technical Field

[0001] The utility model relates to the field of optical lens processing, in particular to a fixing fixture used for optical lens processing. Background Art

[0002] Optical lenses are widely used in life, such as glasses, cameras, medical equipment, etc. Optical lenses are lenses made of optical glass. They have specific requirements for optical properties such as refractive index, dispersion, transmittance, spectral transmittance and light absorption, and glass with uniform optical properties. Qualified glass blocks are heated and forged to make optical lens blanks. The optical lens blanks are subsequently processed to finally make optical lenses. During the processing, the optical lens blanks need to be limited by clamps.

[0003] When traditional clamps are used to fix lenses, the positions of the calipers on both sides are usually adjusted to fix the lenses. However, since most optical lenses are elliptical, the contact area between the calipers on both sides and the edges of the lenses is small, resulting in poor firmness in the fixation of the lenses, and even the inability to clamp the optical lenses, which is inconvenient to use. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content

[0007] Preferably, an angle ruler is installed on the surface of the rectangular frame, the angle ruler corresponds to one of the connecting columns, and the center of the angle ruler and the center of one of the gears are on the same vertical horizontal line.

[0008] Preferably, a connecting rod is fixedly connected to the connecting column, a pointer is installed on the top of the connecting rod, and the pointer is placed above the angle ruler.
