[0053] It should be noted that the locking block 103f penetrates through the clamping block through hole 103i, and the clamping block 103b plays a limiting role. The initial state of the locking block 103f connected with the limiting spring 103e is that the locking block 103f blocks the buckle groove 101c-2.

[0054] In use, the fastener can be understood whether it is buckled or not according to the alarm sound. When the card 103a needs to be embedded into the shell assembly 101, first, the push block 103g is pulled to move along the moving groove 101c-1, and the locking block 103f moves towards the limiting groove 103d, when the locking block 103f reaches the limiting groove 103d, the locking block 103f just does not block the buckle groove 101c-2, at this time, the card 103a can be embedded into the shell assembly 101 along the buckle groove 101c-2, after the card 103a is embedded into the shell assembly 101, the push block 103g is released, and the locking block 103f returns to the initial state under the action of the limiting spring 103e, just blocking the buckle groove 101c-2 to limit the freedom of the card 103a. At the same time, the partition plate 103h fixedly connected with the locking block 103f separates the card 103a from the buzzer 102b to form two independent spaces, after the card 103a is embedded into the shell assembly 101, the buckle elastic tab 102d is pressed, the buckle micro switch 102c is pressed, at the beginning, the buckle micro switch 102c is in the normally closed contact, and forms a path with the buzzer 102b and the battery pack 102a, the buzzer 102b emits an alarm sound, when the buckle micro switch 102c is pressed, the normally closed contact will be converted into a normally open contact, the alarm sound stops, if the buckle is not buckled, the alarm sound will sound again, reminding the staff to buckle the buckle, which well protects the safety of the staff.

[0055] In summary, the safety belt has the beneficial effects that the card 103a can be embedded into the shell assembly 101 by pressing the push block 103g to buckle the buckle, and when the card 103a is embedded in the shell assembly 101 and buckled, the buckle elastic tab 102d is pressed to convert the contact of the buckle micro switch 102c from normally closed to normally open, so that the buzzer 102b stops the alarm sound, and when the buckle is not buckled, the alarm sound will sound again to remind the staff.
