In a first aspect, referring to FIGS. 1 to 13 , an embodiment of the present disclosure provides a throat cuff, including a strip-shaped cuff 1 .

The band 1 includes a connecting segment 11 and a locking segment 12 arranged along the length direction 91 of the band 1 (see FIG. 3 ).

The connecting section 11 is fixedly connected to the lock base 3, the lock base 3 is connected to the swing arm 4 that can swing relative to the lock base 3 in the length direction 91, the swing arm 4 is connected to the active pawl 221 that can swing relative to the swing arm 4 in the length direction 91, The end of the active pawl 221 faces the connecting segment 11 . A pawl elastic member 84 is connected between the lock base 3 and the active pawl 221 . The pawl spring 84 is used to apply a force to the active pawl 221 away from the locking segment 12 in the length direction 91 . The strap 1 can be bent so that the locking section 12 overlaps the connecting section 11 . When the locking segment 12 and the connecting segment 11 are stacked, the active pawl 221 can engage with the ratchet tooth 21 to prevent the locking segment 12 from withdrawing.

1 to 6, the lock base 3 is connected to the active pawl 221 through the swing arm 4, and the strap 1 can be bent so that the locking segment 12 extends into the end of the connection segment 11 and the active pawl 221 (towards the connection segment 11). between the ends) (that is, the locking section 12 and the connecting section 11 are superimposed), so that the strap 1 can form a "ring", and at this time, even if the user releases the swing arm, the active pawl 221 can also be locked with the ratchet tooth 21 Together, the locking segment 12 (toward the left in FIG. 4 ) is prevented from exiting the position between the connecting segment 11 and the end of the active pawl 221 , so as to fix the shape of the cuff 1 and realize the “locking” of the throat cuff.

In some embodiments, the active pawl 221 is also exerted by the pawl spring 84 with a force away from the locking segment 12 in the length direction 91, ie, a thrust from right to left in FIG. 4 (and optionally a thrust toward the connecting segment). ), thus referring to FIGS. 7 to 11 , when swinging the swing arm 4, after each time the active pawl 221 is separated from the ratchet tooth 21, the active pawl 221 will move to the most “away” position from the locking segment 12, so that When the swing arm 4 continues to swing, the next ratchet tooth 21 is "hanged" (the two ratchet teeth 21 with the function of calibration are shown in black in Figs. 7 to 11 ) to achieve further "locking".

Although the cuff 1 can be bent to form a "loop", the cuff 1 in a throat cuff product is not always in a "loop" state, such as an "open" (or substantially straight) state.
