The side panels 3 on both sides of the positioning frame 1 limit the connecting shaft 6 and the main shaft 17 respectively, so that the connecting shaft 6 and the main shaft 17 are more stable to use. The limit lock sleeve 4 installed on the outside of the connecting shaft 6 limits the output wheel 5, and the use position of the output wheel 5 is controlled by the limit lock sleeve 4. The connecting shaft 6 is limited by the first limit seat 2 and the side panel 3 to ensure the overall rotation of the connecting shaft 6. The output wheel 5 is protected by the limit lock sleeve 4 to change the matching relationship between the fixed plug 21 and the rotating plug 13.

[0030] Furthermore, a limiting groove 7 is provided on the left side of the outer arc surface of the connecting shaft 6, and a slot 8 connecting shaft is provided on the left side of the limiting groove 7 on the outer arc surface of the connecting shaft 6.
