The driven gear 11 and the linkage gear 19 of each gear set are rotatably installed in the rear housing 3 in a single degree of freedom, respectively, and the non-circular connecting shaft 1 can be selectively inserted into the non-circular hole 18 of the driven gear 11 and the linkage gear 19 of one of the gear sets through a through hole at the top of the rear housing 3.
By adopting the above technical scheme, if the noncircular connecting shaft 1 is inserted into the noncircular holes 19 of the driven gear 11 and the linkage gear 19 on the right side, when the push rod 2 slides backward, only the linkage gear 19 on the right side rotates counterclockwise with the driven gear 11 on the right side, so that the swing arm 22 swings backward to pull the door inner handle in the backward direction, the driven gear 11 on the left side and the linkage gear 19 on the left side slide, and the linkage gear 19 on the left side does not rotate with the driven gear 11 on the left side. On the contrary, when the noncircular connecting shaft 1 is inserted into the noncircular holes 19 of the left driven gear 11 and the interlocking gear 19, only the left interlocking gear 19 rotates counterclockwise with the left driven gear 11 when the push rod 2 slides backward, so that the swing arm 22 swings forward to pull the door inner handle in the forward direction, the right driven gear 11 and the right interlocking gear 19 slip, and the right interlocking gear 19 does not rotate with the right driven gear 11.
In a further preferred embodiment, as shown in fig. 1, the front housing 10 and the rear housing 3 are each provided with a connecting lug 25 for the fixed attachment to a vehicle door 26. When the automobile door inner decorative plate is installed, holes can be drilled in the automobile door inner decorative plate in advance, and then screws penetrate through the connecting lugs 25 to fix the front shell 10 and the rear shell 3 on the inner side of the automobile door 26, so that the installation is convenient; in order to adapt to the curved surface structure of the vehicle door inner decorative plate, a supporting sleeve with proper length can be sleeved on the part of the screw penetrating through the connecting lug 25, so that the stability of the fixed installation of the front shell 10 and the rear shell 3 is ensured.
