When the push rod 41 moves to the fourth position, the push rod 41 can drive the key cylinder 21 to move to the second position, and the lock cylinder 21 releases the lock of the lead seal cord 3.

Wherein, the lead sealing rope 3 can adopt a steel wire rope or a plastic rope. The fixed end of the lead sealing rope 3 can be fixed on the shell 1 through a rope pressing head. The free end of the lead sealing rope 3 can penetrate through one end of the lock hole and then penetrate out of the other end of the lock hole. Optionally, a lock hole extends through the housing 1 and the lock head 2.

In use, the lead seal strand 3 is passed around the article to be protected or locked and cannot physically be removed from a portion of the lead seal strand, such as a hole or closed loop. And then the free end of the lead sealing rope 3 is inserted into the lock hole along the first direction, and the lock cylinder 21 is positioned at the first position, so that lead sealing is completed. When the lead sealing needs to be released, the lock cylinder 21 is moved to the second position by pushing the push rod 41, so that the lock cylinder 21 is unlocked from the lead sealing rope 3, and then the lead sealing rope 3 is drawn out of the lock hole.

The second position may be any position at which the lock cylinder 21 can unlock the lead seal cord 3. The fourth position may be any position that can urge the lock cylinder 21 to move to the second position.

The lock cylinder 21 comprises a core body, a retainer and a plurality of locking steel balls 211, wherein the plurality of locking steel balls 211 are arranged on the core body through the retainer to form the integral lock cylinder 21. The taper surface 221 tapers in the second direction. Optionally, three locking balls 211 are disposed around the axis of the lock cylinder 21.

For the sake of clarity, the lead sealing strip according to the embodiment of the present invention defines the direction in which the lead sealing rope 3 penetrates into the lock hole as the first direction, and the direction in which the lead sealing rope 3 is drawn out of the lock hole as the second direction. I.e. the first direction and the second direction are opposite directions in the direction of extension of the locking hole. The push rod 41 is movable in the second direction to a third position or in the first direction to a fourth position. Alternatively, a lock hole penetrates the push rod 41.
