when the operating component is converted from the withdrawing state to the applying state of the acting force (F), the acting force (F) presses the locking claw (4) downwards through the control handle (3) to overcome the spring force of the return spring (6) to drive the control handle (3) to move downwards, the locking claw supporting boss (4-2) is kept supported on the lower edge (5a1) of the locking claw bracket supporting hole (5a), and the control handle (3) drives the locking claw (4) to rotate downwards around the lower edge (5a1) of the locking claw bracket supporting hole (5a) until the locking claw tooth (4-1) is disengaged from the locking groove (1a) of the lower sliding rail (1) to enable the automobile seat sliding rail mechanism to enter an unlocking state;
when the operating component is changed from application to cancellation of the acting force (F), under the spring force of the return spring (6), the locking claw supporting boss (4-2) is kept supported on the lower edge (5a1) of the locking claw support supporting hole (5a), the locking claw (4) is driven to rotate upwards around the lower edge (5a1) of the locking claw support supporting hole (5a) until the locking claw tooth (4-1) is clamped in the locking groove (1a) of the lower sliding rail (1), and the locking claw (4) drives the control handle (3) to reset upwards, so that the automobile seat sliding rail mechanism enters a locking state.
2. The automotive seat track mechanism according to claim 1, characterized in that: the top surface of the locking claw (4) is provided with a guide slot (4a) and a limiting claw (4-3); the lock claw bracket (5) is also provided with a guide bolt (5-1) and a limiting piece (5-2);
the guide plug (5-1) is inserted into the guide slot (4a) such that: when the locking claw (4) rotates downwards or upwards around the lower edge (5a1) of the locking claw bracket bearing hole (5a), the locking claw (4) rotates along the guide bolt (5-1);
the limiting claw (4-3) extends into a limiting hole (5-2a) of the limiting part (5-2) so that: when the automobile seat slide rail mechanism is in an unlocked state, the limiting piece (5-2) limits the limiting claw (4-3) to move downwards, so that the locking claw (4) is limited to stop rotating downwards around the lower edge (5a1) of the locking claw support bearing hole (5 a);
when the automobile seat slide rail mechanism is in a locked state, the lower part (3-2) of the control handle (3) abuts against the inner side wall of the top surface of the upper slide rail (2) so as to limit the locking claw (4) from stopping rotating upwards around the lower edge (5a1) of the locking claw support bearing hole (5 a).
3. The automobile seat slide rail mechanism according to claim 2, wherein: the reset spring (6) and the locking claw (4) and the locking claw bracket (5) are connected in the following way:
the reset spring (6) is a torsion spring formed by sequentially connecting a first hook part (6-1), a straight line part (6-2), a bent part (6-3) and a second hook part (6-4);

the first hook part (6-1) is hung on the hook (5-3), the straight line section (6-2) is supported on the reset spring supporting part (5-4), and the second hook part (6-4) is clamped in the reset spring mounting groove (4 b).
4. The automobile seat slide rail mechanism according to claim 3, wherein: the locking claw support (5) is further provided with an assembly groove (5b) which protrudes downward from the lower edge (5a1) of the locking claw support hole (5 a).
5. The automotive seat track mechanism according to claim 4, characterized in that: the locking claw (4) is provided with two locking claw supporting bosses (4-2) and two guide slots (4 a); the locking claw support (5) is provided with two locking claw support supporting holes (5a), two assembling grooves (5b) and two guide bolts (5-1).
6. The automobile seat slide rail mechanism according to any one of claims 1 to 5, wherein: the locking claw bracket (5) is also provided with a guide plate (5-5); a limiting boss (3-3) is arranged on one side surface of the lower part (3-2) of the control handle; in the process of mutually switching the locking state and the unlocking state of the automobile seat slide rail mechanism, the limiting boss (3-3) is kept in contact with the inner wall of the side face of the upper slide rail (2), and the other side face of the lower part (3-2) of the control handle is kept in contact with the guide plate (5-5).
7. The automobile seat slide rail mechanism according to any one of claims 1 to 5, wherein: the locking claw support (5) is riveted and fixed on the top surface of the upper sliding rail (2) through a rivet (7).
8. The automobile seat slide rail mechanism according to any one of claims 1 to 5, wherein: the operating assembly is positioned outside the upper sliding rail (2) and is provided with a swing arm (8), a rotating pin (9) and an operating assembly bracket (10); the operation assembly support (10) is fixedly connected with the upper sliding rail (2), and the middle part of the swing arm (8) is rotatably connected with the operation assembly support (10) through the rotating pin (9), so that: one of the ends of the swing arm (8) is seated on the lever upper part (3-1) of the lever (3) to apply the downward force (F) to the lever upper part (3-1) of the lever (3) through the end of the swing arm (8).
9. The automotive seat track mechanism according to claim 8, characterized in that: the operating assembly is also provided with a sound-deadening pad (12); the sound-absorbing pad (12) is fixed to the operating assembly support (10), and the sound-absorbing pad (12) is located above the swing arm (8) in such a way that: when the operating assembly is deactivated by the force (F), the swing arm (8) bears against the sound-damping pad (12).
10. The automotive seat track mechanism according to claim 8, characterized in that: the operating component support (10) is fixed on the top surface of the upper sliding rail (2) in a welding mode.
