[0010] Compared with the prior art, the advantages of the utility model are as follows: through its structural design, the person being interrogated can lean his back against the chair back after sitting on the chair seat, and then the table frame can be closed by the hinge, so that the foot fixing ring on the table frame fixes the legs of the person being interrogated to the chair seat, and the table frame can be connected to the armrest seat with a lock to start fixing the hands of the person being interrogated. When fixing the hands of the person being interrogated, the rotating shaft on the armrest seat is rotated, and the rotation of the rotating shaft drives the rope collection roller to rotate, and the rotation of the rope collection roller drives two steel wire ropes to be wound around the rope collection roller. In the process of the steel wire rope winding around the rope collection roller, the steel wire rope connected to the tension spring drives the tension spring to move, and the movement of the tension spring drives the ratchet block to move toward the inside of the positioning base, so that the ratchet block and the ratchet bar are no longer engaged, and at the same time, the steel wire rope connected to the half-moon ring can drive the half-moon ring to rotate and open. When the half-moon ring is not fully opened and the ratchet block slides to the end, the steel wire rope connected to the tension spring will continue to pull the tension spring, and the force generated by the tension spring tightening the steel wire rope will be absorbed to keep the half-moon ring fully opened. After the half-moon ring is fully opened, the hands of the person being interrogated can be placed on the positioning base. When the hands of the person being interrogated are placed, the rotating shaft is released, the torsion spring drives the half-moon ring to reset, and the supporting spring drives the ratchet block to reset. At this time, the ratchet bar and the ratchet block engage with each other to fix the hands of the person being interrogated by the half-moon ring. In the above manner, when the person being interrogated needs to sign or press fingerprints, the detention police only needs to stand behind the person being interrogated and rotate the rotating shaft to complete the release of the person being interrogated's hands, avoiding the danger of close contact with the suspect in order to unlock the handcuffs, thereby protecting the personal safety of the detention police.

[0023] Through the personnel in this field, all the electrical components in this case are connected to their corresponding power supplies through wires, and a suitable controller should be selected according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection between the electrical components is completed in the order of working in sequence. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and no longer explains the electrical control.
[0024] In this embodiment, after the interrogated person sits on the chair seat 1, he / she leans his / her back against the chair back 2, and the cushion 16 on the chair seat 1 reduces the pressure damage caused by the hard material to the interrogated person, and then the table frame 14 is closed by the hinge, so that the foot fixing ring 15 on the table frame 14 fixes the interrogated person's legs to the chair seat 1, and the table frame 14 is connected to the armrest seat 3 with a lock to start fixing the interrogated person's hands. When fixing the interrogated person's hands, the rotating shaft 4 on the armrest seat 3 is rotated, and the rotation of the rotating shaft 4 drives the rope collection roller 5 to rotate, and the rope is collected. The roller 5 rotates to drive the two steel wire ropes 6 to wind around the rope-collecting roller 5. The multiple rollers 19 in the armrest seat 3 can prevent the steel wire rope 6 from rubbing against the armrest seat 3, thereby extending the service life of the steel wire rope 6. In the process of the steel wire rope 6 winding around the rope-collecting roller 5, the steel wire rope 6 connected to the tension spring 10 drives the tension spring 10 to move, and the movement of the tension spring 10 drives the ratchet block 11 to move toward the inside of the positioning base 9, so that the ratchet block 11 and the ratchet bar 8 are no longer engaged. At the same time, the steel wire rope 6 connected to the half-moon ring 7 can drive the half-moon ring 7 to rotate and open. When the half-moon ring 7 is fully opened and the ratchet block 11 slides to the end, the wire rope 6 connected to the tension spring 10 will then pull the tension spring 10, and the tension spring 10 will absorb the force generated by the tightening of the wire rope 6 to keep the half-moon ring 7 fully opened. After the half-moon ring 7 is fully opened, the hand of the interrogated person can be placed on the positioning base 3. When the hand of the interrogated person is placed, the rotating shaft 4 is released, the torsion spring 21 drives the half-moon ring 7 to return to its original position, and the support spring 12 drives the ratchet block 11 to return to its original position. At this time, the ratchet bar 8 and the ratchet block 11 are engaged with each other so that the half-moon ring 7 fixes the hand of the interrogated person. During the interrogation process, the buffer spring 17 and the head cushion 18 on the chair back 2 can prevent the interrogated person from getting emotional and hurting himself. In the above manner, when the interrogated person needs to sign or fingerprint, the custody police only needs to stand behind the interrogated person and rotate the rotating shaft 4 to free the hands of the interrogated person, thus avoiding the danger of close contact with the criminal suspect in order to unlock the handcuffs, protecting the personal safety of the custody police, and the touch display screen 20 on the table frame 14 can enable the interrogated person to sign and collect fingerprints.
