[0058] The elastic structure 17 is two, and the two elastic structures 17 are rotationally symmetrical along the central axis of the unlocking square column 16.

[0059] In fact, only one elastic structure 17 can be used according to actual conditions, and in fact, only one elastic structure 17 can be used according to actual conditions in the embodiment, and the elastic structure 17 is provided with two, and the elastic structure 17 is rotationally symmetrical along the central axis of the unlocking square column 16, so that the axial offset force borne by the top pressing block 15 can be balanced, and the practicability is high.

[0060] The guide plate 18 is fixedly installed with the steel bowl 11, and the steel bowl 11 forms a cladding to the edge of the large-toothed plate 12;

[0061] The guide plate 18 is rotatably installed with the large-toothed plate 12 through the steel bowl 11;

[0062] The yield strength of steel cup 11 is ≥460MPa.

[0063] In fact, the yield strength of the steel cup 11 can be set to other parameters according to the actual situation. In this embodiment, by limiting the yield strength of the steel cup 11 to ≥460MPa, the problem of the steel cup 11 being slightly deformed due to the force of the angle adjuster when the seat is under load can be avoided, which would cause abnormal noise due to friction between the steel cup 11 and the large tooth plate 12 during the movement of the large tooth plate 12. This method is highly practical.
