[0046] The specific solution is as follows: when the staff uses the device, they first move the device to a suitable position. When the medical staff adjusts the height of the device, they first start the servo motor 225 to rotate the rotating shaft 221 fixedly connected to the output end of the servo motor 225, and the rotating rotating shaft 221 drives the second support rod 223 fixedly connected thereto to rotate, and during the rotation process, the second support rod 223 drives the other first support rod 222 to rotate synchronously through the pulley 226 set on the bottom rotating shaft 221, thereby realizing the control of the inclination angle of the adjustment component 22, and then realizing the horizontal height of the Aege loading unit 224, and the shaft 2231 set on the first support rod 222 and the second support rod 223 realizes the limit fixation of the loading plate 2232, so as to ensure that the materials displayed on the loading plate 2232 have good stability, and the first arc on the long board 41 The plate 31 and the second arc plate 32 ensure that the first support rod 222 and the second support rod 223 will not be offset during the rotation process, and when the medical staff adjusts the vertical height of the loading plate 2232, the silk thread inside it can be timely reeled in by the reel 56 to avoid the silk thread from being knotted and entangled inside the device. During the movement of the slide plate 53, the gear 1 541 on the slide bar 54 rotates under the drive of the tooth plate 511, and the rotating gear 1 541 drives the slide bar 54 fixedly connected thereto to rotate, and then drives the reel roller 561 to rotate and reel in through the pulley 2 573. The pressing plate 62 arranged on the side wall of the baffle 6 realizes that when the reel roller 561 reels in the wire, the diameter of the reel roller 561 increases, and the pressing plate 62, pushed by the elastic force of the spring 63, can ensure that the silk thread contracted on the reel roller 561 is in a straight state.
