[0002] Generally, after the semi-finished VR lens is formed by the injection molding process and taken out, considering that the lens is formed into an injection-molded part by the insert injection molding method, a shearing machine device is generally used to shear and separate the lens body and the blank handle that make up the injection-molded lens. At the same time, most of the existing shearing machines use two cutter members that move up and down to quickly cut off the positioned blank handle so that it can be quickly separated from the lens.

[0003] An injection-molded lens shearing machine with adjustable shearing length, with the publication number of CN220972551U, includes a shearing vertical frame. The upper part inside the shearing vertical frame is slidably connected with a movable support plate. The front end of the bottom of the movable support plate is provided with a front clamping seat. The rear end of the bottom of the movable support plate is fixedly connected with a rear clamping seat. One ends of the rear clamping seat and the front clamping seat close to the middle of the movable support plate are respectively fixedly connected with a steering support.

[0004] In the above solution, although there are many benefits, there are also the following defects: when adjusting the distance between the two cutter bodies according to the radius of the placed lens, people need to concentrate on the operation. After a long time, the staff will be fatigued, resulting in a certain difference between the adjusted distance and the lens distance, and there will be a situation where there is blank residue after shearing, and it needs to be sheared again. The use effect is not very good, reducing the practicability of the device. Summary of the Invention
