Detailed Description

The following further illustrates embodiments of the invention:

as shown in fig. 1 to 9, the invention discloses a drive conversion structure, which comprises a secondary input gear 1, a clutch transmission gear 2, a lock tongue pushing gear 3, a clutch input gear 4, a clutch dial wheel 5 and a transmission gear 7, wherein the lock tongue pushing gear is meshed with the clutch transmission gear, the transmission gear 7 is meshed with the clutch input gear 4, and the clutch dial wheel 5 is sleeved inside the clutch input gear 4;

the clutch dial wheel 5 can be linked with the clutch input gear 4 and the clutch transmission gear 2, so that the transmission gear 7 drives the clutch input gear 4 to rotate and drives the clutch transmission gear 2 to rotate, and the lock tongue is driven to push the gear 3 to rotate;

or, after the clutch dial wheel 5 rotates by a certain angle, the clutch dial wheel 5 is linked with the clutch transmission gear 2, the clutch input gear 4 is disconnected from the clutch dial wheel 5, the secondary input gear 1 drives the clutch dial wheel 5 to rotate, and the clutch dial wheel drives 5 to drive the clutch transmission gear 2 to rotate, so that the lock tongue is driven to drive the gear 3 to rotate.

When the clutch thumb wheel is linked with the clutch input gear, the clutch bead is arranged between the top bead surface A and the bead concave surface E and is positioned in the ball groove C. When the clutch dial wheel and the clutch input gear are disconnected in linkage, the clutch ball is arranged inside the concave surface A.

The invention is characterized in that an input gear 1, a clutch transmission gear 2, a bolt pushing gear 3, a clutch input gear 4, a clutch dial wheel 5 and a transmission gear 7 are fixed on a driving component lower cover 6, and a plurality of positioning shafts 10 are arranged on the driving component lower cover

As shown in fig. 1, the secondary input gear 1 includes an annular sliding groove 11, and a boss 12 is disposed inside the annular sliding groove and extends upward toward the annular sliding groove.

As shown in FIG. 2, the clutch transmission gear 2 comprises two ball grooves C21, a groove surface B22 and a torsion spring clamping point B23, and the ball grooves C21 are arranged symmetrically left and right.

As shown in fig. 3, a ball concave surface E41 is provided inside the clutch input gear 4, and the ball concave surface E is formed by recessing a main body portion of the clutch input gear inwards. The bead concave surface E41 is arc-shaped, and the bead concave surface E is provided with a bottom support which can support the clutch bead, and the clutch bead can be attached to the bead concave surface E.
