The fixed end 6 is provided with seals at two ends of the T-shaped groove to prevent the sliding end 5 from sliding out of the T-shaped groove.

An angle adjusting mechanism is arranged at the rotary joint of the backrest 3 and the chair back 1. The angle adjusting mechanism comprises a worm gear 42, and the worm gear 42 is fixedly connected with a rotating shaft of the chair back 1. The meshing is connected with worm 43 on the worm wheel 42, the one end of worm 43 is provided with driven conical gear 44, the meshing is connected with initiative conical gear 45 on the driven conical gear 44, initiative conical gear 45 and driven conical gear 44 are 90 degrees contained angles and initiative conical gear 45 is on a parallel with the symmetry axis of worm wheel 42. The driving bevel gear 45 is connected with an adjusting wheel 41, and a plurality of circular arc teeth are arranged on the side surface of the adjusting wheel 41, so that the adjusting wheel 41 can be rotated manually. The unidirectional transmission of the worm gear and the worm can ensure that the angle of the seat cannot change automatically under the condition of stress, thereby increasing the reliability; the worm 43 is connected with a bevel gear pair, so that the adjusting wheel 41 is positioned at a place where the seat can naturally reach on the side surface of the seat and is parallel to the rotating shaft of the seat back 1, and the seat can be adjusted more conveniently. The structure of the angle adjustment mechanism is shown in fig. 6 and 7.

When the safety seat is not used, the seat back 1 is fixedly connected with the rear row of the automobile through the snap fasteners at the back of the seat back; after the seat cushion 2 and the seat back 1 are adjusted in place, the backrest 3 is fixedly connected with the rear row of the automobile through snap fasteners at the back of the backrest, so that the safety seat can be firmly fixed with the automobile after being adjusted in place. More specifically, the back parts of the chair back 1 and the backrest 3 are provided with male buckles of snap fasteners, cylindrical protrusions are arranged on the male buckles, and arc-shaped protruding parts are arranged at the outer ends of the cylindrical protrusions; the automobile is characterized in that a female buckle of a snap fastener is arranged at the corresponding position of the automobile, a hole is formed in the female buckle, and two parallel metal springs are arranged in the hole and used for clamping a protruding part of a male buckle. When not using or expand to target in place the back, the box is fixed to the vertical insertion of pin thread, and the power that car seat received is the horizontal direction power for the majority, can not make pin thread and box mutual separation.

Following the utility model discloses a theory of operation carries out simple explanation: when the safety seat is not used, the cushion 2 and the chair back 1 are folded together to be used as a chair cushion 7 of the automobile seat; when the safety seat is used, the seat cushion 2 is unfolded anticlockwise and leans on the backrest 3, the chair back 1 is lifted upwards to separate a male buckle at the back of the seat cushion from a female buckle at the rear row of the automobile, the chair back 1 of the safety seat, the seat cushion 2 and the backrest 3 of the automobile seat move towards the head of the automobile and rotate anticlockwise, and the male buckle on the backrest 3 is inserted into the female buckle of the seat cushion 7 to be fixed after the chair back 1 and the seat cushion 2 move in place and rotate in the right direction.
