Why can't ps take pictures with one hand when it is turned on?

When PS is turned on, there is only one hand to grasp the picture, so it cannot be operated for the following reasons:

The last time I used Photoshop, I didn't turn off the gripper, but the function of the gripper is to move the canvas, that is, when I need to see the picture beyond my visual range after magnifying it with a magnifying glass, I use the gripper to move the canvas.

Solution:

Use the shortcut key v to return to the initial tool, or click the move tool to continue to the next step.
