[0008] A chest adjustment structure of a sitting posture corrector, comprising:

[0009] Top chest piece;

[0010] A fixing member, the fixing member being fixed to one end of the top chest member;

[0011] Two abutting members, both of which are slidably mounted on one end of the fixing member and are symmetrically arranged on both sides;

[0012] The adjusting component is provided with a mounting groove on the top chest piece, and the adjusting component is installed in the mounting groove. The adjusting component comprises:

[0013] A right linkage member, wherein the right linkage member is slidably mounted in the mounting groove;

[0014] A left linkage member, wherein the left linkage member is slidably mounted on the right linkage member;

[0015] A gear, a mounting post is fixed to the inner wall of the mounting groove, a circular hole is opened on the gear for the mounting post to pass through, the gear is located between the left linkage member and the right linkage member, and the inner sides of the left linkage member and the right linkage member are provided with a plurality of linkage teeth distributed at equal intervals, and the plurality of linkage teeth are meshed with the gear;
