However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0029] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0030] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs. Example

[0031] like Figures 1 to 5 As shown, it includes a fixed plate 1 and two fixed blocks 2 for fixing and limiting the wrist of psychiatric nursing infusion. Two symmetrical movable grooves 6 are arranged on the top of the fixed plate 1. The inner side walls of the two movable grooves 6 are rotatably connected with threaded rods 3. One end of the threaded rod 3 passes through the side wall of the movable groove 6 and is connected with the rotating shaft of the turntable 4. The turntable 4 is rotatably connected with the side wall of the fixed plate 1. An eccentric column is arranged at one end of the turntable 4. The eccentric column is held tightly by hand to drive the turntable 4 to rotate. The turntable 4 drives the connected threaded rod 3 to rotate through the connected rotating shaft, so that the threaded block threadedly connected with the threaded rod 3 moves inside the movable groove 6. Because a fixed block 2 for easy movement and limiting fixing is welded on the top of the threaded block, the movable fixed block 2 is slidably connected to the top of the fixed plate 1, and then under the drive of the turntable 4, the spacing between the welded fixed block 2 and the movable fixed block 2 is flexibly adjusted according to the length of the patient's arm, which is convenient for operation.
