The driven gear 11 and the linkage gear 19 of each gear set are respectively rotatably arranged in the rear shell 3 in a single degree of freedom, 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 gear set through a through hole in the top of the rear shell 3.
With the above technical solution, if the non-circular connecting shaft 1 is inserted into the non-circular holes 19 of the right driven gear 11 and the linkage gear 19, when the push rod 2 slides backwards, only the right linkage gear 19 rotates counterclockwise with the right driven gear 11, so that the swing arm 22 swings backwards to pull the door inner handle backwards, the left driven gear 11 and the left linkage gear 19 slip, and the left linkage gear 19 does not rotate with the left driven gear 11. On the contrary, when the non-circular connecting shaft 1 is inserted into the non-circular holes 19 of the left driven gear 11 and the interlocking gear 19, when the push rod 2 slides backward, only the left interlocking gear 19 rotates clockwise and counterclockwise with the left driven gear 11, so that the swing arm 22 swings forward to open the door inner handle in the forward direction, the right driven gear 11 and the right interlocking gear 19 slide, and the right interlocking gear 19 does not rotate with the right driven gear 11.
In another preferred embodiment, as shown in fig. 1, the front case 10 and the rear case 3 are respectively provided with engaging lugs 25 for fixedly mounting with a vehicle door 26. During installation, holes can be drilled in the vehicle door trim panel 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 vehicle door 26, so that the installation is convenient; moreover, in order to adapt to the curved surface structure of the door trim panel, a support sleeve with a proper length can be sleeved on the part of the screw passing 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.
