[0121] During the assembly process, the conveying component 8 is used to drive the jig 11 to each component in accordance with the assembly sequence; after the lever 31 pulls the locking tongue 101 to rotate it, during the process of the conveying component 8 driving the jig 11 to move, the action rod 32 will contact the inclined surface 130 of the reset plate 13. Since the inclined surface 130 extends in the direction close to the slotted side wall 109 along the conveying direction of the conveying component 8, during the movement of the jig 11, the action rod 32 will move along with the jig 11 while moving toward the slotted side wall 109, and the lever 31 will be reset accordingly, with a simple structure and low cost.

[0122] like Figure 6 and Figure 7 See also Fig.14 and Fig.15 The action rod 32 includes a support rod 320 and a first bearing 321; one end of the support rod 320 is fixedly connected to the push-pull rod 30, and the other end is fixedly penetrated by the first bearing 321; the rotation plane of the first bearing 321 is horizontal; in the process of resetting the lever 31, the first bearing 321 contacts the inclined surface 130 of the reset plate 13, and under the action of the reset plate 13, the support rod 320 is driven to reset the lever 31.
