After the initial clamping, push the operating handle to make the positioning groove approach the positioning column, and then continue to rotate The handle is operated to make the second buffer spring elastically deform. At this time, the corresponding positioning groove is sleeved on the positioning column to complete the fixing of the operation handle. Then start the walking chassis through the control unit, and move to the destination by itself with the cooperation of the lidar sensor and the navigation map built into the control unit. When forward or backward is obstructed, the arc-shaped anti-collision buffer shrapnel will buffer to avoid damage to the device.
