[0081] Three, the spring seat 32, spring 29, positioning ring body 6 are assembled together as a small component, when the spring 29 is installed on the spring seat 32, the positioning ring body 6 is installed on the spring seat 32 through the cooperation of the inner limiting bump 35 and the axial limiting sliding hole 36, at this time the positioning ring body 6 is outwardly bounced due to the rebound force, and the inner limiting bump 35 and the axial limiting sliding hole 36 between the spring seat 32 and the positioning ring body 6 can be buckled, so that the positioning ring body 6 in the small component is always subjected to the spring action;

[0082] Four, the spring seat 32 on the small component is inserted into the positioner movable slot 27 for installation, the axial insertion slot 34 on the spring seat 32 and the convex rib 33 on the bottom surface of the positioner movable slot 27 are positioned, and one end of the positioning ring body 6 is inserted into the positioner movable slot 27 through the cooperation of the outer limiting bump 28 and the axial limiting sliding groove 37 (the positioning ring body 6 can slide axially in the positioner movable slot 27 and cannot rotate relative to the positioner movable slot 27);

[0083] Five, the rotating guide seat 9 is fixedly installed and positioned with the handle outer shell 3 through the screw two 22, and the other end of the positioning ring body 6 is located in the guide groove 10 on the rotating guide seat 9, the ring teeth one 30 on the positioning ring body 6 are pressed on the ring teeth two 31 on the bottom surface of the guide groove 10 under the elastic force of the spring 29, and the ring teeth one 30 and the ring teeth two 31 are positioned and locked through the meshing therebetween;

[0084] Six, the handle right shell 15 is covered on the handle left shell 14 for buckling and fixing.

[0085] The principle of the real-time hovering and full-angle rotation use of the second technical scheme of the utility model:

[0086] When the handle outer shell 3 rotates relative to the main body outer shell 1, the rotating guide seat 9 also rotates relative to the rotating base 5, at this time, as long as the applied rotating torque is greater than the static locking force, the meshed tooth positions between the ring teeth one 30 and the ring teeth two 31 enter the next position, thereby completing the 360° full-angle rotation and real-time hovering and stopping use.

[0087] The annular boss 17 and the limiting rib 18 between the rotating base 5 and the handle shell protruding ring mouth 4 form the first layer of rotating guide (the rotating gap is 0.1mm on one side), and the wire routing pipe 23 on the rotating base 5 and the wire routing pipe through hole 24 on the rotating guide seat 9 form the second layer of rotating guide (the rotating gap is 0.1mm on one side), and the two layers of guide structures guarantee that the handle outer shell 3 and the main body outer shell 1 slide evenly without jamming when rotating.

[0088] The two wire harness limiting columns 25 position the wire harness coming out of the wire routing hole, and the wire harness is fixed through the wire pressing plate 26, so that the wire harness inside the handle outer shell 3 can remain stationary when the whole machine is in rotation use.
