The specific meanings of the above terms in the present invention can be understood in a specific case to those of ordinary skill in the art.

In the present invention, unless otherwise expressly stated or limited, "above" or "below" a first feature means that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact with each other via another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. "beneath," "under" and "beneath" a first feature includes the first feature being directly beneath and obliquely beneath the second feature, or simply indicating that the first feature is at a lesser elevation than the second feature.

In the description of the present embodiment, the terms "upper", "lower", "left", "right", and the like are used based on the orientations and positional relationships shown in the drawings only for convenience of description and simplification of operation, and do not indicate or imply that the referred device or element must have a specific orientation, be configured and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used only for descriptive purposes and are not intended to have a special meaning.

As shown in fig. 1, a seat back angle adjustment mechanism, including adjustment handle 1, first pin 2, slip handle 3, fixed plate 5, spring 7, second pin 8, wherein the bottom swing joint of adjustment handle 1 is in the below of fixed plate 5, and the below of adjustment handle 1 passes through spring 7 and connects on fixed plate 5, the top of adjustment handle 1 is fixed with first pin 2, slip handle 3 connects the top at fixed plate 5 through pivot 4, and be located the place ahead of adjustment handle 1, and first pin 2 cooperation is connected in the corner of slip handle 3, fixed plate 5 left side top is fixed with and is used for carrying out spacing second pin 8 to adjustment handle 1 top.

The use process of the utility model is as follows:
