The B end component 8 comprises a link plug riveting base three 801, a link plug riveting base four 802, a BL end link plug riveting base 803, and a B end link plug riveting base 804. The six terminal pins in the prior art are improved into eight terminal pins, which can achieve eight rows of power supply modes and further effectively meet the demand of multiple power supply positions on the electrical appliance.

[0025] The reset component 6 comprises a spring 601, a bullet head 602, and a reset protrusion 603. The reset protrusion 603 is fixedly sleeved on the operation shaft 5. One end of the spring 601 is fixedly connected with the inner wall of the A base link shell 2 or the B base link shell 3, and the other end is fixedly connected with the bullet head 602. The round head of the bullet head 602 abuts against the reset protrusion 603. The rotating shaft 4 drives the operation shaft 5 to rotate, thereby driving the reset protrusion 603 to rotate. When the bullet head 602 abuts against the reset protrusion 603, the reset protrusion 603 is in a protruding state. At this time, the bullet head 602 can push the reset protrusion 603 under the elastic force of the spring 601, so that the reset protrusion 603 drives the operation shaft 5 to rotate until the initial position is reached, thereby achieving the reset function.

[0026] The A end component 7 further comprises a switching spring one 705 and a switching spring two 706. The switching spring one 705 and the switching spring two 706 are clamped into the A base link shell 2. One end of the switching spring one 705 is clamped on the protrusion of the link plug riveting base one 701, and one end of the switching spring two 706 is clamped on the protrusion of the link plug riveting base two 702.

The switching spring one 705 and the switching spring two 706 are always connected with the link plug riveting base one 701 and the link plug riveting base two 702, respectively. The operation shaft 5 is rotated to push the switching spring one 705 or the switching spring two 706, so that the switching spring one 705 or the switching spring two 706 is deformed, thereby making the movable contact one 707 on the switching spring one 705 or the switching spring two 706 contact with the static contact riveting end one 708, and realizing the connection of the corresponding position.

[0027] The B end part 8 further comprises a switching elastic sheet three 805 and a switching elastic sheet four 806, which are clamped into the B base link shell 3. One end of the switching elastic sheet three 805 is clamped on the protrusion of the link plug-in riveting base three 801, and one end of the switching elastic sheet four 806 is clamped on the protrusion of the link plug-in riveting base four 802. The other end of the switching elastic sheet three 805 and the switching elastic sheet four 806 is fixedly installed with a movable contact two 807. The BL end link plug-in riveting base 803 and the B end link plug-in riveting base 804 are fixedly installed with a static contact riveting end two 808. The switching elastic sheet three 805 or the switching elastic sheet four 806 is rotated and pushed by the operation shaft 5, so that the switching elastic sheet three 805 or the switching elastic sheet four 806 is deformed, and then the movable contact two 807 on the switching elastic sheet three 805 or the switching elastic sheet four 806 is in contact with the static contact riveting end two 808, realizing the communication of the corresponding gear;

The lower concave part between the two groups of reset protrusions 603 is a clamping groove. The clamping groove is arranged so that when rotated to a non-reset gear, the bullet head 602 can be clamped (at this time, the force of the bullet head 602 acting on the reset protrusion 603 cannot push the reset protrusion 603 to rotate), thereby avoiding automatic jumping back to the initial gear during normal use.

[0030] A base link shell 2 and B base link shell 3 are provided with an integral separating plate 9, the inner wall of A base link shell 2, B base link shell 3 is provided with a through hole 10, the inner wall of A base link shell 2, B base link shell 3 is provided with a positioning groove 11, the outer wall of A base link shell 2, B base link shell 3 is provided with an integral inclined clamping plate 12, the separating plate 9 is used for separating the switching spring 1 705 and the switching spring 2 706, and the switching spring 3 805 and the switching spring 4 806, the through hole 10 ensures that the link plug riveting base 1 701, the link plug riveting base 2 702, the AL end link plug riveting base 703, the A end link plug riveting base 704, the link plug riveting base 3 801, the link plug riveting base 4 802, the BL end link plug riveting base 803, the B end link plug riveting base 804 can be extended from A base link shell 2 and B base link shell 3, the positioning groove 11 is used for the position of the static contact riveting end 1 708 and the static contact riveting end 2 808, and the inclined clamping plate 12 is used for clamping A base link shell 2 and B base link shell 3 to the shell 1.

[0031] Working principle: in use, by rotating the rotating shaft 4 drives the operating shaft 5 to rotate, the operating shaft 5 rotates and the top driving protrusion 501 on the operating shaft 5 pushes the switching spring 1 705, the switching spring 2 706, the switching spring 3 805 and the switching spring 4 806, so that the switching spring 1 705 or the switching spring 2 706 is deformed, and then the movable contact 1 707 on the switching spring 1 705 or the switching spring 2 706 is in contact with the static contact riveting end 1 708, and the switching spring 3 805 or the switching spring 4 806 is deformed, and then the movable contact 2 807 on the switching spring 3 805 or the switching spring 4 806 is in contact with the static contact riveting end 2 808, so as to realize the switching of the gear, and when the operating shaft 5 rotates, the reset protrusion 603 can be driven to rotate, when rotating to the reset gear, at this time the bullet head 602 is abutted against the reset protrusion 603, and the bullet head 602 can drive the reset protrusion 603 under the action of the spring 601, so that the reset protrusion 603 drives the operating shaft 5 to rotate until the initial gear is rotated, and the reset function is realized.
