The laser depth marker is described in the following sections:
trigger switch 4: when the hydraulic press presses the probe rod fork, the hydraulic press is closed, and when the hydraulic press leaves, the hydraulic press is closed. The distance measurement collection process of the marker is triggered when the switch is closed, and the distance measurement collection is stopped when the switch is opened.
