[0029] Next, specifically describe the specific settings and functions of its adjusting structure 6 and auxiliary structure 7.

[0030] Refer to Figure 2 、 Figure 3 As shown in the figure, in this implementation scheme: The adjusting structure 6 includes two fixing blocks 601. The two fixing blocks 601 are fixedly connected to the support plate 3. A rotating shaft 602 is rotatably connected to the inner wall of the fixing block 601. A positioning plate 603 is fixedly connected to the arc surface of the rotating shaft 602. A fixing plate 606 is fixedly connected to the lower surface of the support plate 3. An adjusting rod 607 is rotatably connected to the side of the fixing plate 606 close to the positioning plate 603. A clamping plate 608 is threadedly connected to the arc surface of the adjusting rod 607. Two sliding rods 609 are fixedly connected to the side of the fixing plate 606 close to the adjusting rod 607. The arc surfaces of the two sliding rods 609 are slidably connected to the clamping plate 608. The two positioning plates 603 are used to further limit the upper arm of the patient, preventing the patient's arm movement from affecting the injection operation. The operation is simple and the practicability is high. Soft pads 604 are fixedly connected to the side of the two positioning plates 603 close to each other. The soft pads 604 are silicone pads. The softness of the surface of the positioning plate 603 is increased through the soft pads 604, improving comfort and reducing the discomfort generated when the positioning plate 603 acts on the patient. A number of anti-slip protrusions 605 are fixedly connected to the end of the rotating shaft 602 close to the clamping plate 608. The anti-slip protrusions 605 are in a sharp cone shape. The friction at one end of the rotating shaft 602 is increased through the anti-slip protrusions 605, making the limiting effect of the clamping plate 608 on the rotating shaft 602 better. Anti-slip pads 610 are fixedly connected to the side of the clamping plate 608 close to the fixing plate 606 at the positions corresponding to the two rotating shafts 602. The anti-slip pads 610 are rubber pads. The friction on the surface of the clamping plate 608 is increased through the anti-slip pads 610, further improving the limiting effect of the clamping plate 608 on the rotating shaft 602.

[0031] Refer to Figure 4As shown in the figure, in this embodiment: The auxiliary structure 7 includes a fixing frame 71, the fixing frame 71 is fixedly connected to the support plate 3, a round rod 72 is rotatably connected to the inner wall of the fixing frame 71, an auxiliary frame 73 is fixedly connected to the arc surface of the round rod 72, a coil spring 74 is sleeved on the arc surface of the round rod 72, and the two ends of the coil spring 74 are respectively fixedly connected to the fixing frame 71 and the auxiliary frame 73. The auxiliary frame 73 is used to clamp and fix the nursing pad laid on the cushion 4 to prevent the nursing pad from shifting. The operation is simple and convenient, and the practicability is high. One side of the auxiliary frame 73 away from the support plate 3 is fixedly connected with an auxiliary block 75, and a plurality of anti-slip lines are arranged on the upper surface of the auxiliary block 75. By operating the auxiliary block 75 to drive the auxiliary frame 73 to rotate, it is convenient for the user to rotate the auxiliary frame 73.

The protective cover 76 is used to shield and protect the coil spring 74 and extend its service life.

[0032] Detailed description of the usage method: By setting the adjusting structure 6, first rotate the adjusting rod 607 on the fixing plate 606. The adjusting rod 607 drives the clamping plate 608 to move away from the rotating shaft 602 along the sliding rod 609 by means of the thread, releasing the limit on the rotating shaft 602. At this time, rotate the two positioning plates 603 in the direction of approaching each other so that the two positioning plates 603 are close to both sides of the patient's arm. During this process, the positioning plate 603 drives the rotating shaft 602 to rotate along the fixing block 601. Then rotate the adjusting rod 607 in the opposite direction. The adjusting rod 607 drives the clamping plate 608 to move towards the rotating shaft 602 by means of the thread until the clamping plate 608 tightly presses against the rotating shaft 602 to fix the angle of the positioning plate 603. Among them, the soft pad 604 is used to increase the softness of the surface of the positioning plate 603, improve the comfort, and reduce the discomfort generated when the positioning plate 603 acts on the patient. The anti-slip protrusion 605 is used to increase the friction at one end of the rotating shaft 602, so that the limiting effect of the clamping plate 608 on the rotating shaft 602 is better. The anti-slip pad 610 is used to increase the friction on the surface of the clamping plate 608, further improving the limiting effect of the clamping plate 608 on the rotating shaft 602.

[0033] By setting the auxiliary structure 7, first rotate the auxiliary frame 73 in the direction away from the cushion 4. The auxiliary frame 73 drives the round rod 72 to rotate along the fixing frame 71. The coil spring 74 always gives the auxiliary frame 73 a torsional force. Then lay the nursing pad on the cushion 4 and release the auxiliary frame 73. The auxiliary frame 73 rotates in the direction of approaching the cushion 4 under the action of the torsional force of the coil spring 74 until the auxiliary frame 73 presses the nursing pad against the cushion 4. Among them, by operating the auxiliary block 75 to drive the auxiliary frame 73 to rotate, it is convenient for the user to rotate the auxiliary frame 73. The protective cover 76 is used to shield and protect the coil spring 74 and extend its service life.
