When the second binding belt 4 descends to the ankle of the patient, the second threaded rod 39 stops rotating to stop rotating the fourth rotating shaft 14, and the first bevel gear 40 rotates to drive the second bevel gear 13 to reciprocate on the fourth rotating shaft 14 under the action of elastic potential energy of the spring 42, so that the injury to the ankle of the patient caused by the fact that the arm of the patient is not fixed after the leg of the patient is fixed can be effectively avoided, and the second binding belt 4 descends continuously.

After the patient is treated, the leg is taken out from the second binding belt 4, the first bevel gear 40 and the second bevel gear 13 are meshed again under the action of elastic potential energy of the spring 42, and the second binding belt 4 can be reset by reversing the driving motor 30.

It should be noted that, as shown in fig. 1, the initial positions of the moving frame 5 and the first restraint strap 6 are lower, and the initial position of the second restraint strap 4 is higher, i.e. after the patient sits on the seat 1 with a shorter or higher height, after the two arms respectively pass through the first restraint strap 6 and the legs respectively pass through the second restraint strap 4, the first restraint strap 6 and the second restraint strap 4 can be adjusted to a proper position for adapting to the height of the patient along with the opening of the driving motor 30.

Working principle: when the psychiatric adjustable constraint chair is used, a patient sits on the chair seat 1, the back of the patient naturally leans against the chair back 10, two arms of the patient respectively pass through the two constraint belts I6, and then the legs of the patient respectively pass through the two constraint belts II 4.

Then, the driving motor 30 is started to drive the first rotating shaft 31 to start rotating, and the first rotating shaft 31 drives the first two threaded rods 28 to start rotating so as to drive the first moving block 38 and the second moving block 25 to move towards the direction approaching to each other, and the telescopic frame 20 hinged above the first moving block 38 and the second moving block 25 starts to shrink upwards, so that the moving frame 5 and the first binding belt 6 synchronously move upwards.

Along with the rotation of the first threaded rod 28, the third moving block 24 is driven to move leftwards, so that the first binding belt 6 moves towards the direction close to the outer side of the seat 1 while moving upwards, and the device can be suitable for fixing arms of patients with different heights.

After the driving motor 30 is started, the rotation of the first rotating shaft 31 also drives the first gear 34 to start rotating, and drives the second gear 36 to reversely rotate, so that the two rack rows 35 move upwards to drive the chair back 10 fixedly connected with the rack rows to synchronously move upwards, and the upward movement of the chair back 10 can ensure that patients with different heights can lean against the central position of the chair back 10 on one hand, so that the comfort level of the patients is enhanced, and on the other hand, the back of the patients can be massaged under the action of the arc-shaped protrusions 9 on the surface of the chair back 10, so that the tension feeling of the mental patients is reduced, and the follow-up treatment of the patients is facilitated.

Under the action of the belt pulley transmission mechanism II 33, the rotation of the rotation shaft I31 drives the rotation shaft III 12 to synchronously rotate, and under the action of the bevel gear transmission mechanism I13 and the bevel gear transmission mechanism 29, the threaded rod II 39 is driven to start rotating, and the threaded rod II 39 rotates to drive the moving block IV to move downwards, so that the binding belt II 4 moves downwards, and the binding belt II 4 can be adapted to fix the legs of patients with different heights.

To sum up, after the driving motor 30 is started, the first binding belt 6, the second binding belt 4 and the chair back 10 can be adjusted to the proper positions for adapting to the height of the patient according to the height of the patient, so as to fix the patients with different heights.
