With the tab 11 in the second abutting state with the tab mount 13, the second tab portion 112 abuts against a face of the mount plate 131 away from the lock pin 21.
The tab mount 13 has an X-direction, a Y-direction and a Z-direction perpendicular to each other. The axial direction of the lock pin 21 is parallel to the Z direction, the length of the second tab portion 112 in the X direction is smaller than the length of the first tab portion 111 in the X direction, the second tab portion 112 can protrude into the mounting hole 1311, and the first tab portion 111 cannot protrude into the mounting hole 1311. The second tab portion 112 extends into the mounting hole 1311, and the first tab portion 111 abuts against the mounting plate 131 of the tab mounting bracket 13 outside the mounting hole 1311, which is the first abutting state.
The mounting hole 1311 may have a complex shape in which a circle and a rectangle intersect.
Wherein the diameter of the circle is larger than the width of the rectangle in the Y direction, and the diameter of the circle is smaller than the length of the rectangle in the X direction. In one embodiment of the application, the mounting hole has a compound shape in which the center of the circle coincides with the intersection of the diagonals of the rectangle. That is, the circle may be located at the center of the rectangle. Referring to fig. 2, the second collar part 112 and the connecting member 12 may be bolted together. The circular holes are convenient for the bolts to pass through, and the rectangular holes on the outer sides of the circular holes are only used for the second ring-pulling part 112 to pass through, so that the size of the rectangular holes in the Y direction can be smaller. Of course, the application is not limited to a specific shape of the mounting hole 1311.
In one embodiment of the present application, the tab mounting bracket 13 may be of a U-shaped configuration, with the mounting plate 131 being one arm of the U-shaped configuration. The U-shaped bottom of the tab mount 13 may have tab mount mounting holes for mounting the tab mount 13 to the door body.
