insert 42 which are connected with the strap and the fixing belt
end. Two fixing belts 3 are arranged at the positions, close to the
top, of the back side of the backrest 101, the strap 2 penetrates
through the two fixing belts, the junction of the initial end of
the strap 2 and the chair frame 1 is spaced away from the junction
of the final end of the strap 2 and the chair frame 1 by a certain
distance, and the distance is generally larger than the hand width
so that the chair can be lifted upwards conveniently. As is shown
in FIG. 3, the strap 2 is matched with the fixing belts 3 to form a
double-shoulder carrying structure; as is shown in FIG. 4, the
strap 2 is matched with the fixing belts 3 to form a hand carrying
structure; as is shown in FIG. 5, the strap 2 is matched with the
fixing belts 3 to forth a single-shoulder carrying structure.
[0024] The sitting state mentioned above refers to the backrest 101
being approximately perpendicular to the chair seat 102 in
position, and the lying state refers to the backrest 101 being
approximately horizontal to the chair seat 102 in position.
[0025] As is shown in FIG. 1 and FIG. 2, a buckle belt is arranged
on the reverse side of the chair seat 102 and connected with an
insertion base, a buckle belt is arranged on the back side of the
backrest 101 and connected with an insertion head, and the
