The end of the positioning bolt 45 is pressed on the anti-slip pattern to fix the angle of the protective cover 44. A power-assisting rod is fixed on the positioning bolt 45 to help rotate. The protective cover 44 is a three-quarter tube, which concentrates and protects the cables and changes the angle and position of the cables. A groove for the tensioning spring 46 to pass through is provided in the middle of the upper side of the rear plug 4 to form a stable opening and closing state.

[0037] The working principle of the present invention is: when in use, the fixing sleeve 47 is put on the cable, and after the cable passes through the outlet, it is connected to the front plug 3 through the terminal 31, and the rear plug 4 is clamped to the front plug 3, and the connection is fixed by a nut, and then the screw 23 is rotated to connect the drive rod with the connecting column 22, and the sealing ring 32 is sealed, and finally the fixing sleeve 47 is tightened by the thread to complete the connection between the cable and the plug 2.

[0038] When it is necessary to connect to the aviation plug socket 1, pick up the plug 2, lift it up diagonally to the rear, pinch the pressure pieces 33 on both sides with two fingers, and after pressing, the connecting rod 34 is pressed forward by the pressure piece 33, and the strong spring 35 is compressed, and the lower side of the plug 2 slides into the lower clamping strip 15, and then rotates to a vertical state, and the plug 2 is inserted between the inner ring 12 and the outer ring 11 of the aviation plug socket 1, and the two fingers are released. The pressure piece 33 is bounced up by the strong spring 35, and then drives the connecting rod 34 to move backward, and then compresses the oblique plug 1 36 to rotate, and then drives the oblique plug 2 37 to insert into the front plug 3, completing the initial fixation.

[0039] Then rotate the pry bar 43, which in turn drives the power gear 42 to rotate, and the power gear 42 drives the driving wheel 41 to rotate, which in turn drives the driving rod to move forward, drives the connecting column 22 to move forward, drives the upper clamping strip 21 to tilt up, and the upper clamping strip 21 is inserted into the upper clamping groove 14 to complete the overall fixation. The tensioning spring 46 is contracted to the shortest and is still in a stretched state. When the angle of the cable needs to be adjusted, the cable is inserted into the fixing sleeve 47. After the front and rear directions are adjusted, the positioning bolt 45 is rotated to determine the angle of the fixing sleeve 47 to complete the overall installation. Finally, the position of the screw 23 needs to be adjusted. Turn the plug 2 clockwise to determine whether there is any shaking. If it is not tight, turn the screw 23 to tighten it.

[0040] When disassembly is required, the cable is separated from the fixing sleeve 47, the pry bar 43 can be rotated, the tension spring 46 is stretched, the upper clamping strip 21 releases the aviation plug socket 1, and two fingers are pressed on the pressing piece 33 to drive the connecting rod 34 to move, quickly unlocking the plug 2, which is convenient for operation. When installing, just operate counterclockwise, which is simple and quick.
