The lock tongue 3 is pivoted to the seat body 1, one end of the lock tongue 3 abuts against the pressing portion 21, and the second elastic reset member 5 is arranged between the lock tongue 3 and the seat body 1, so that the lock tongue 3 can be rotationally moved. Therefore, when the pressing switch 2 is pressed to release the lock tongue 3, the lock tongue 3 can be rotated and unlocked under the elastic force of the second elastic reset member 5. When the pressing force is removed, the pressing switch 2 is restored under the restoring force of the first elastic reset member 4, so that the pressing portion 21 abuts against the lock tongue 3 again, and the lock tongue 3 is locked. Therefore, the entire security lock only needs to be unlocked by pressing the pressing switch 2, and is locked after the hand is released. The unlocking and locking are realized by using the pressing switch 2, the first elastic reset member 4, the lock tongue 3 and the second elastic reset member 5, the structure is very simple, and the operation is very convenient.
[0029] The structure of the lock cylinder 8 involved in the pressing type automobile engine cover security lock 100 is well known to those skilled in the art, and will not be described in detail here.
