[0043] Specifically, in this embodiment, the operating table 151 is installed after the two single-sided frames 11 are unfolded. Through the setting of the operating table 151, the restraint structure 15 not only has the function of restricting the patient's movements, but can also be used by the patient in daily manual rehabilitation training, eating and other scenarios, which is beneficial to the rehabilitation of patients with mental illness; the card slot 152 cooperates with the armrest 114 so that the restraint structure 15 slides on the armrest 114. When sliding to the appropriate position, the restraint structure 15 can maintain a suitable distance from the patient; through the cooperation of the locking rod 154, the first locking hole 153 and the second locking hole 1141, the disassembly and locking of the restraint structure 15 can be achieved.

[0044] In other embodiments, the operating table 151 can also be designed to be folded from the middle to cooperate with the expansion or folding of the two hip support blocks 131 and the two back support blocks 141; and, the two sides of the operating table 151 can be rotatably connected to the two armrests 114 or the two single-sided frames 11 through two connecting arms, so that the operating table 151 can be rotated around the armrests 114 or the single-sided frames 11 through the connecting arms; under this setting, when the present invention is not in use, the operating table 151 can be transferred to the back of the back support structure 14 through the connecting arms for folding and storage. When the present invention is expanded and used, the user can first sit on the hip support structure 13, and then the operating table 151 can be rotated from the top of the user's head to the front of the user through the connecting arms, thereby achieving the purpose of quick restraint.

[0045] In addition, a matching buckle structure can be provided between the operating table 151 and the hip support structure 13, and the buckle structure is located between the legs of the user when buckled; after the operating table 151 reaches the restraining position, the aforementioned buckle structure can be used to increase the restraining effect of the present invention and reinforce the operating table 151 to prevent the user from lifting the operating table 151.

[0046] Please continue reading Figure 6-8 , wherein the single-sided frame 11 also includes a reinforcement rod 115 arranged between two ground support rods 112, and a suction cup bracket 116; the suction cup bracket 116 is arranged on the reinforcement rod 115 and / or the ground support rod 112 on one side close to the back support rod 113.

[0047] Specifically, the structural strength of the single-sided frame 11 can be increased through the design of the reinforcement rod 115, and the suction cup bracket 116 can be provided with an installation carrier for the suction cup mechanism 2; in addition, as needed, the suction cup bracket 116 can be set on the reinforcement rod 115, the ground support rod 112 close to the side of the back support rod 113, or the suction cup bracket 116 can be set on both.

[0048] Please read further Figure 6-8 , wherein the suction cup mechanism 2 includes a suction cup shell 22 arranged on one side of the suction cup bracket 116 and used to accommodate the suction cup 21; the suction cup mechanism 2 also includes an adjusting portion 23 that cooperates with the suction cup bracket 116 through a threaded structure; the adjusting portion 23 is used to push the suction cup 21 out of the suction cup shell 22.

[0049] Specifically, the adjustment part 23 includes an adjustment hand wheel and a screw, and the suction cup bracket 116 includes a threaded hole that cooperates with the aforementioned screw. The user can control the adjustment part 23 to move in the suction cup bracket 116 by turning the adjustment hand wheel; when the screw moves toward the suction cup shell 22, the suction cup 21 can be pushed out of the suction cup shell 22, so that the suction cup 21 is sucked into the ground and / or wall, so as to fix the utility model, making it difficult for the patient to move with the utility model.

[0050] It is worth mentioning that when the suction cup 21 is attracted to the wall, a wall made of ceramic tiles has a better fixing effect.

[0051] Please read further Figure 6-8 The suction cup housing 22 has a cavity 221, a through hole 222 and a reset spring 223 arranged in the cavity 221; the suction cup 21 includes a suction cup body 211, a movable rod 212, a reset disk 213 and a connecting portion 214 arranged in sequence; the connecting portion 214 is connected to the adjusting portion 23; the reset spring 223 is arranged between the reset disk 213 and the bottom wall of the cavity 221.

[0052] Specifically, the connecting portion 214 is connected to the adjusting portion 23, so when the aforementioned screw moves, the adjusting portion 23 can move the suction cup 21 in the suction cup housing 22; through the coordinated design of the reset spring 223, the reset disk 213 and the bottom wall of the cavity 221, the action of the screw pressing down the suction cup 21 is more stable, and when the suction cup 21 needs to be separated from the ground and / or the wall, it can cooperate with the screw to make the disengagement action more convenient.

[0053] The above description is only for the best embodiment of the utility model, but it cannot be understood as a limitation of the claims.
