The optical axis lock head is a new type of material roll fixing device that uses self-locking technology to replace traditional screw fastening methods. It enables quick locking and release through an internal self-locking mechanism, significantly improving loading and unloading efficiency.The lock head can be easily pulled out by simply pressing the handle with one hand and gently pulling it backward, making the operation convenient and efficient.

Specific operation steps are as follows:

1.Hold between points A and B, press your fingernail against component A, and apply force to component B.

2.Pull components A and B apart a certain distance until you feel movement, indicating that the parts are loosened. This state is the unlocked position.

3.Maintain the gap between points A and B to keep the components in the unlocked state, then pull the entire assembly outward from the optical axis.

The installation method involves first ensuring the entire assembly is in the unlocked state, then pushing it inward to the specified position, and finally releasing points A and B to lock it in place.
