• the first inner cylindrical column and the outer cylindrical column are relatively fixed;
• the second inner cylindrical column vertically and telescopically slides with respect to the first inner cylindrical column;
• the spring provides an elastic force for the second inner cylindrical column to slide obliquely upwards;
• the second inner cylindrical column is provided with a sliding groove;
• the first inner cylindrical column and the second inner cylindrical column are connected with a pull rod arranged therebetween;
• a hook portion on a top of the pull rod is able to slide in the sliding groove;
• the sliding groove has a first positioning point and a second positioning point;
• the first positioning point is located below the second positioning point;
• the sliding groove comprises a first track and a second track connecting the first positioning point and the second positioning point;
• the first track and the second track are both unidirectional tracks;
• the hook portion is able to move from the first positioning point to the second positioning point through the first track;
• the hook portion is able to move from the second positioning point to the first positioning point through the second track;
• a middle of the cover is provided with a cable clip for clamping the cable;
• and the plug connector is able to pass through the first inner cylindrical column and the second inner cylindrical column;
• an outer periphery of the cover is provided with a sealing ring;
• the cover is detachably arranged above the second inner cylindrical column;
• when the hook portion is at the second positioning point, the sealing ring abuts against and seals an inner surface of the outer cylindrical column;
• and when the hook portion is at the first positioning point, an abutting and sealing state between the sealing ring and the inner surface of the outer cylindrical column is released.
