[0028] When the device is needed to detect a certain door, the device is first adjusted according to the height of the door handle position so that the gripping mechanism can better grip the door handle. The height is adjusted first, and the operation display counting controller 8 controls the first motor 9 to start, so that the bevel gear set 10 transmits the action of the first motor 9 to the screw 11, so that the screw 11 rotates. The rotation of the screw 11 will drive the moving block 14 to move vertically on the outer surface of the screw 11 with the moving plate. When the height is adjusted to the appropriate level, the first motor 9 is controlled to stop working. At this time, the vertical position of the guide plate 6 has been determined.

[0032] When the guide plate 6 is positioned, the sliding sleeve 7 is used to slide the gripping mechanism on the guide plate 6. After finding a suitable gripping position, the pull rod 29 is pulled to allow the long arc plate 28 to slide along the inner surfaces of the three short arc plates 27.
