There are multiple protruding blocks 252, and the position and shape of the protruding blocks 252 are adapted to the groove 144. The protruding block 252 is inserted into the groove 144 to assist in fixing the position of the headrest assembly 2. The positioning rod 253 passes through the outer shell 21 and is inserted into the limiting hole 143 to fix the position of the headrest assembly 2.

[0048] like Figure 5 As shown, a first spring 2521 is provided on the protruding block 252, and the protruding block 252 is connected to the housing 21 via the first spring 2521; the positioning rod 253 includes an insert rod 2531, a positioning pin 2532 and a second spring 2533, the insert rod 2531 is connected to the positioning pin 2532, the insert rod 2531 is inserted into the limiting hole 143, and the second spring 2533 is provided in the positioning pin 2532.

[0049] When the position of the headrest assembly 2 needs to be adjusted, the positioning pin 2532 is moved away from the lifting assembly 14, so that the insertion rod 2531 leaves the limiting hole 143, the second spring 2533 is compressed, and the positioning pin 2532 is moved along the lifting assembly 14 to make the headrest assembly 2 rotate along the lifting assembly 14 with the connecting shaft 12 as the axis. During the movement, the protrusion block 252 squeezes the first spring 2521, so that the protrusion block 252 leaves the groove 144.

[0050] When the position of the headrest assembly 2 needs to be fixed, the positioning pin 2532 is released, and the second spring 2533 is restored from the compressed state to drive the positioning pin 2532 to move in the direction of the limiting hole 143, so that the insertion rod 2531 is inserted into the limiting hole 143, and the first spring 2521 is restored from the compressed state to drive the protrusion block 252 into the groove 144, thereby fixing the position of the headrest assembly 2.

[0051] Example 3

[0052] Another specific embodiment of the utility model is as follows Figure 6-7 As shown, the difference from Example 2 is that a telescopic rod 34 is arranged between the fixed end 31 and the movable end 33, and the telescopic rod 34 passes through the movable end 33 and is connected with the fixed end 31, so that the movable end 33 can move along the telescopic rod 34 and the connecting shaft 12, thereby adjusting the width of the arm placement slot assembly 3 according to the patient's arm circumference.

[0053] like Figure 7 As shown, the telescopic rod 34 includes a handle 341, a pull rod 342 and a fixed rod 343. The fixed rod 343 is connected to the fixed end 31. The pull rod 342 passes through the movable end 33 and is connected to the handle 341. The pull rod 342 is inside the fixed rod 343. The pull rod 342 can move along the fixed rod 343. A positioning button 3421 is provided on the pull rod 342. A plurality of fixing holes 3431 are provided on the fixed rod 343. The positioning button 3421 is inside the fixing hole 3431. The positioning button 3421 cooperates with the fixing hole 3431 to fix the movement of the pull rod 342 inside the fixed rod 341.

[0054] like Figure 8 As shown, the positioning button 3421 is connected to the pull rod 342 through the positioning spring 3422. By moving the handle 341 to drive the pull rod 3422 to move along the fixed rod 343, the distance between the fixed end 31 and the movable end 33 can be changed. When the pull rod 3422 is pulled, the positioning button 3421 is squeezed by the fixed hole 3431 to cause the positioning spring 3422 to contract, and the positioning button 3421 enters the pull rod 342, so that the pull rod can move along the fixed rod 343; when the positioning button 3421 moves to the next fixed hole 3431, the positioning spring 3422 rebounds to cause the positioning button 3421 to enter the fixed hole 3431, thereby fixing the distance between the fixed end 31 and the movable end 33.

[0055] Preferably, straps are provided on the movable end 33 and the fixed end 31 to fix the patient's arm.

[0056] Compared with the prior art, the CT examination headrest of the utility model can adjust the inclination angle of the patient's head by setting the lifting component 14 and the headrest component 2, so as to help the patient maintain the body position required for the examination; the arm placement slot component 3 adjusts the distance between the fixed end 31 and the movable end 33 by setting the telescopic rod 34, so as to meet the arm placement requirements of patients with different arm circumferences; by setting the adjustment component 4, the angles of the two arm placement slot components 3 can be adjusted synchronously, so that patients with diseases such as periarthritis of the shoulder and cervical spondylosis can keep their hands raised above their heads during examination without the assistance of medical staff; by setting the anti-slip strip 13 and the shoulder strap 211, the patient's shoulders and neck can be prevented from sliding down after the angle of the headrest component 2 is adjusted.
