[0029] In one or more embodiments of the present invention, a limiting hole is provided on the second fixing seat 6 , and a limiting protrusion is provided on the inner side of the unlocking arm 8 . The limiting protrusion is located in the limiting hole, thereby limiting the rotation angle of the unlocking arm 8 .

[0030] In this embodiment, the limiting hole is fan-shaped to accommodate the rotation of the unlocking arm 8 .

[0031] In one or more embodiments of the present invention, a wave washer is sleeved on the rotating shaft 7 .

[0032] In this embodiment, the provision of the corrugated washer eliminates the movement clearance of the unlocking arm 8 and prevents it from shaking.

[0033] In one or more embodiments of the present invention, a first protrusion 31 and a second protrusion 32 are formed on the inner side of the sliding bracket 3, and a first groove and a second groove are formed between the first protrusion 31, the second protrusion 32 and the inner side of the first fixed seat 2. The openings of the first groove and the second groove are in opposite directions. An elastic shaft 11 is provided in the first groove and the second groove, and the other end of the elastic shaft 11 is fixed to the unlocking tooth piece 5.

[0034] In this embodiment, one side of the unlocking tooth piece 5 is folded outward to form a side plate, which is located on the upper side of the locking plate 51, and the folding directions of the two are opposite. A card hole is provided on the side plate, and the other end of the elastic shaft 11 is clamped in the card hole. Through the elastic force of the elastic shaft 11, after the manpower is withdrawn, the corresponding fixed tooth piece 21 is engaged with the locking hole 52 through its elastic force, so that the sliding bracket 3 is fixed in the adjusted position.

[0035] Working principle of this utility model:

[0036] A foot unlocking assembly is added to the unlocking handle 4, and the foot applies a downward force to the foot unlocking assembly, and the force is transmitted to the unlocking handle 4, so that the unlocking handle 4 is driven upward, so that the fixed point between the sliding bracket 3 and the first fixed seat 2 is separated, so that the sliding bracket 3 can move along the length direction of the first fixed seat 2, so as to achieve the purpose of unlocking. After unlocking, the front and rear positions of the sliding bracket 3 are adjusted by manpower. After the manpower is withdrawn, the elastic force of the elastic shaft 11 makes the corresponding fixed tooth piece 21 engage with the lock hole 52, so that the sliding bracket 3 is fixed in the adjusted position, thereby completing the adjustment of the front and rear positions of the seat.
