Description

Termination Cuffs {The mittens a not release}

The present invention relates to a cuff for preventing the release of the cuff so that it cannot be released except for the designated key in the cuffing of the cuff. More specifically, the cuff of the cuff is lowered to the front of the teeth of the step of engaging the hook. Forming an inclined groove, even if a thin plate or pin is inserted into the gap of the moving ring moving path to which the moving ring is moved, the moving ring moving path can no longer be introduced, thereby preventing unauthorized handcuffs. It relates to a cuff to prevent termination.

In general, various types of handcuffs have been proposed, but the conventional handcuffs are fixed when the criminal gives a strong impact toward the center of the outer shaft by inserting a plurality of fixing pins from the outside to connect the fixing ring and the step piece. It was easily dismantled by detaching the fixing pin from the ring, and was freely rotated by the shaft that inserted the step of the handcuff. Therefore, the offender gave a strong shock from the outside to cut or detach the shaft to separate / disassemble the handcuff. The work was frequently performed, and the handcuffs could be released by manipulating a fine pin such as a hairpin from the outside and manipulating the step of the step.

Therefore, the present applicant has steadily improved such a conventional handcuff structure through the Korean Utility Model Publication Nos. 1993-204, 1993-2996, and 1996-3984, and especially when using handcuffs on a human wrist. It has been proposed with respect to the problem that occurs and the handcuff structure that can be prevented from being terminated by the pin.

The present invention is a further improvement of the above-mentioned problems and also the techniques proposed by the present applicant. The present invention allows the teeth to appear on the moving ring movement path in the body of the handcuff so that they can be maintained and moved with the teeth of the moving ring. Even though the step piece is elastically moved by the latch part of the moving ring by forming a downward inclined groove in the step piece, the thin plate or the pin is no longer moved by the downward slope groove between the tooth of the step piece and the ratchet part of the moving ring. It is intended to provide a cuff for preventing the second and third crimes by preventing the moving passage from being moved between the ratchet portion of the moving ring and the teeth of the walking piece due to the introduction of the forced release member. .

The present invention forms a semi-circular arc and has a movable ring having a ratchet portion formed with a plurality of teeth on one side; In addition, a pair of fixed rings formed in the shape of a semi-circular arc and connected to the other side of the moving ring by a rotation shaft, one side of which is rotatably coupled, and a rectangular body formed on the other side; In the handcuff consisting of a diaphragm, a step piece, a leaf spring and a mechanism frame, which constitutes a moving path through which the moving ring can move in the body of the pair of fixed rings, thereby allowing the moving ring to be caught and released. It is characterized in that the downward slope groove is formed in front of the tooth.
