[0021] Example 4 like Figure 11-14As shown, the base 1 includes a slide groove 11 opened on the shell of the base 1 and a left clamp arm assembly 12 and a right clamp arm assembly 13 slidably arranged on the slide groove 11. The slide groove 11 is horizontally opened on the shell of the base 1. The slide groove 11 extends from the left end of the shell of the base 1 to its right end. The slide groove 11 is set as a two-sectioned groove body or a straight groove body with two ends connected; the structure of the left clamp arm assembly 12 and the right clamp arm assembly 13 is the same or non-mirror-image-identical. In this embodiment, the structure of the left clamp arm assembly 12 and the right clamp arm assembly 13 is the same. The left clamp arm assembly 12 includes a shell 300 and a hook 121 rotatably connected to the shell 300. The hook 121 is used to hang garbage bags or other items. The left clamp arm assembly 12, the left clamp arm assembly 12 and the right clamp arm assembly 13 are both equipped with a locking mechanism inside. The locking mechanism is used to lock the left clamp arm assembly 12 and the right clamp arm assembly 13. The structure includes a first tooth pattern 111 arranged on the side wall of the slide groove 11, and the locking mechanism also includes a button body 50 and a second elastic body arranged inside the shell 300. The second elastic body is located below the button body 50, and the two are elastically abutted. The second elastic body is set as a spring or other structure with a certain telescopic rebound. The second elastic body is used for pressing and resetting the button body 50. The button body 50 is provided with a second tooth pattern 501, and the second tooth pattern 501 is meshed with the first tooth pattern 111 on the side wall of the slide groove 11. The button body 50 passes through the corresponding shell 300, and the button body 50 is pressed and connected with the shell 300. When the second tooth pattern 501 on the button body 50 is meshed with the first tooth pattern 111 on the side wall of the slide groove 11, the left clamp arm assembly 12 and the right clamp arm assembly 13 are in a locked state. At this time, the left clamp arm assembly 12 and the right clamp arm assembly 13 cannot be adjusted left and right; In this way, when the user needs to adjust the width between the left clamp arm assembly 12 and the right clamp arm assembly 13, he only needs to press the button body 50, the second elastic body will deform and retract, and the second tooth pattern 501 on the button body 50 will be separated from the first tooth pattern 111 on the side wall of the slide groove 11. At this time, the left clamp arm assembly 12 and the right clamp arm assembly 13 are in an unlocked state.

[0022] Working principle: When in use, adjust the left clamp arm assembly 12 and the right clamp arm assembly 13 to a suitable width, and then clamp them on the two metal connecting rods of the car seat headrest. Then, press the button body 50 on the left clamp arm assembly 12 and the right clamp arm assembly 13. When the locking mechanism is in the unlocked state, the width between the left clamp arm assembly 12 and the right clamp arm assembly 13 is reduced until the left clamp arm assembly 12 and the right clamp arm assembly 13 are firmly clamped on the two metal connecting rods, and the installation of the vehicle-mounted head side pillow is completed; If the user needs to adjust the supporting position of the side pillows 22 on both sides of the human head, the user can press the button column 1001 on the release button 101. At this time, the first elastomer 105 is compressed and deformed, releasing the second teeth 10 on the button 101 and the first teeth 20 on the slide hole 211. At this time, the corresponding side pillows 22 are pushed to a suitable height to achieve the most comfortable state of supporting both sides of the human head, thereby improving the applicability and comfort of the product. Moreover, the user can also rotate the side pillows 22 horizontally to adapt to more different scenarios and user uses.

[0023] In summary, compared with the prior art, the present application provides a sliding hole 211 on the connecting rod 21, and the side pillow 22 is connected to the connecting rod 21 by sliding up and down through a connecting mechanism, so that the user can adjust the height of the side pillow 22 to fit the two sides of the human head more closely, improve the comfort of use, and have stronger applicability. By setting a connecting mechanism, the base 102 on the connecting mechanism is rotatably connected to the fixing seat 104, so that the side pillow 22 fixedly connected to the fixing seat 104 can be rotated in the horizontal direction to adjust the support angle of the side pillow 22, which is very practical. Moreover, by utilizing the damping assembly 103 disposed on the connecting mechanism, the side pillow 22 has a certain damping force when rotating, and the rotation stroke angle of the side pillow 22 can also be locked to prevent the side pillow 22 from rotating at will and affecting the user experience.

[0024] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
