By rotating the lifting rod, the connecting rod causes the locking rod to disengage from the locking hook; then, by moving the movable pin and causing the locking block to disengage from the slot, the insert plate can be separated from the locking frame. At this time, the side plate is disengaged and rotates outward. When the side plate rotates to contact the ground, it becomes a sloping step, which makes it easier for workers to leave the workbench along the side plate, avoiding direct height differences that could cause workers to twist their ankles, thus increasing safety.
