The top post 403 on the second pressing key 401 passes through the travel hole 406. The length of the travel hole 406 is the distance the sliding seat 42 slides back and forth. When the chair tilts backward at a large angle, the extended length of the sliding seat 42 can be stretched to allow the balance block 43 to abut against the seat back, creating a balanced support effect. When the user needs to adjust the length of the sliding seat 42, simply press the second press button 401. The fourth elastic body 402 is compressed and deformed, and the second tooth 404 on the second press button 401 disengages from the third tooth 405 on the inner wall of the fixed seat 41, thus unlocking the chair. The user can then push or pull the sliding seat 42 back and forth, causing the balance block 43 at the front end of the sliding seat 42 to contact the seat back. The side of the balance block 43 that contacts the seat back is covered with flexible silicone or fabric to prevent scratching the leather or plastic of the seat back. Releasing the second press button 401 resets the fourth elastic body 402.The second tooth 404 on the second pressing key 401 engages again with the corresponding third tooth 405, creating a locking effect on the sliding seat 42. The balance block 43 is rotatably connected to the front end of the sliding seat 42 via a damping rotating shaft or universal ball assembly. By adjusting the tilt angle of the balance block 43, it can better conform to the seat back. In this way, by using the balance block 43 that is telescopically connected to the sliding seat 42, a balancing effect can be formed on the support frame assembly 4 to prevent the support frame assembly 4 from swaying forward when braking.
